Is the Iridium 9555 Still King of Sat Phones in 2025? An Off-Grid Showdown
Comprehensive Overview of the Iridium 9555 and Competing Satellite Phones
- Iridium 9555 overview: A rugged handheld satellite phone introduced in 2008, the Iridium 9555 operates on Iridium’s 66-satellite LEO network and offers truly global coverage (pole-to-pole) for voice and text ts2.tech. It remains in production as of 2025 and is trusted for reliable off-grid communication in extreme environments.
- Specs & features: The 9555 has ~4 hours talk / 30 hours standby battery life ts2.tech, weighs 9.4 oz (266 g) and measures ~5.6 × 2.2 × 1.2 in ts2.tech. It features an internal retractable antenna, illuminated 200-character display, and basic SMS/email capability ts2.tech. Notably, it lacks modern extras like GPS navigation or a one-touch SOS button (those are found on Iridium’s more advanced 9575 Extreme model) ts2.tech.
- Pricing & plans: The Iridium 9555 retails around $900–$1,100 USD as of early 2025 ts2.tech. It’s available through specialty retailers and often discounted with service contracts (sometimes even free on multi-year plans) ts2.tech. Iridium airtime is on the pricey side (e.g. ~$1.00/minute on pay-as-you-go), but incoming calls and texts are generally free for the sat phone user gearjunkie.com. Basic monthly plans start around $50–$100 for a small bundle of minutes.
- Competition: Major competitors include Inmarsat’s IsatPhone 2, Thuraya’s XT series, and Globalstar’s GSP-1700. These phones use different satellite networks with varying coverage: Inmarsat covers ~99% of the globe (except polar regions) via three geostationary satellites gearjunkie.com; Thuraya’s two GEO satellites serve ~160 countries across Europe, Africa, Asia, and Australia (no Americas coverage) ts2.tech; Globalstar’s 48 LEO satellites cover most populated areas in North/South America, Europe, and parts of Asia, but leave big gaps in oceans and polar areas ts2.tech ts2.tech.
- 9555 pros and cons: The Iridium 9555’s biggest pros are its 100% global reach and reliable voice quality. Iridium’s low-Earth orbit network means minimal voice delay and clear calls even in remote locales – users report it can feel like a normal cell call with no perceptible lag ts2.tech ts2.tech. It’s also praised for robust construction that survives harsh conditions ts2.tech. Cons: It is more expensive than regional phones, provides only basic features, and its battery life (4 h talk) is shorter than the IsatPhone 2’s beefy 8 h talk time ts2.tech ts2.tech. The 9555 is not waterproof (just “weather-resistant”) and lacks an emergency SOS function gearjunkie.com ts2.tech, so it relies on the user to manually relay GPS coordinates if needed.
- Latest developments (2024–2025): Iridium Communications has finished upgrading its satellite constellation (as of 2019), enhancing call reliability and data services worldwide. In 2023, Iridium partnered with Qualcomm to trial satellite texting on Android phones, but that effort ended as industry trends shifted toward open standards theregister.com. Nonetheless, Iridium’s CEO notes that “the direction of the industry is clear toward increased satellite connectivity in consumer devices” theregister.com, and Iridium is positioning to be a key player. Meanwhile, rival Inmarsat (now part of Viasat) is launching new I-6 and I-8 satellites by 2026 to boost network capacity and even extend coverage closer to the poles gearjunkie.com. Thuraya deployed its next-gen Thuraya-4 NGS satellite in early 2025, aiming to increase bandwidth and regional coverage across EMEA and Central Asia thuraya.com thuraya.com. Additionally, the satellite phone arena faces disruption from mainstream tech: Apple’s iPhone 14/15 can send emergency texts via Globalstar satellites, and SpaceX (Starlink) with T-Mobile is testing direct-to-cell messaging, with plans for satellite voice and data service in the next couple of years gearjunkie.com theregister.com.
Iridium 9555 – A Trusted Global Lifeline
The Iridium 9555 is often regarded as the workhorse of satellite phones – a no-frills device that prioritizes coverage and toughness over fancy features. Launched in late 2008 as a successor to Iridium’s bulky 9505A, the 9555 significantly shrank the form factor (thanks to an internal antenna design) while maintaining Iridium’s hallmark: 100% global coverage ts2.tech. In fact, Iridium remains the only network to offer pole-to-pole coverage, as its 66 satellites orbit the Earth in cross-linked Low Earth Orbits (LEO) ts2.tech. For a user, this means that whether you’re in the middle of the Sahara, on an Antarctic expedition, or sailing at 80° North in the Arctic Ocean, the 9555 can theoretically get a signal anywhere under open sky. Adventure journalist Nick Belcaster attests that in his expeditions “whether in the Amazon Basin or Iceland’s fjords, with enough time, we always get a signal on the Iridium 9555” gearjunkie.com. This reliability in remote areas is a lifesaver – quite literally, as one climber used a 9555 to call a doctor from the Himalayas for a medical emergency gearjunkie.com.
Build and durability: Physically, the Iridium 9555 resembles a classic candy-bar mobile phone (circa early 2000s) but built to military-grade durability. It has a thick, rugged housing with rubberized coating and is designed to handle dust, shocks, and extremes of temperature ts2.tech. While it doesn’t carry an official IP waterproof rating, real-world use shows it tolerates rain and rough handling; just don’t dunk it in water. (For comparison, Iridium’s newer 9575 Extreme model is IP65 rated and MIL-STD-810F rugged ts2.tech, meaning it can withstand water jets and heavy abuse). The 9555’s keypad is weather-resistant and designed to be usable with gloves, and the screen, albeit a small monochrome display, is backlit for night use ts2.tech. The phone weighs about 9.4 ounces – fairly lightweight – and is comfortable to hold. The antenna stows away neatly and flips up when you’re ready to acquire a satellite signal.
Capabilities: As a pure satellite phone, the Iridium 9555’s primary function is two-way voice calls. It also supports SMS messaging (160-character texts) and even short emails (it can send/receive emails by converting them to text format) ts2.tech. Data capabilities are very limited: the 9555 has a mini-USB port for tethering to a laptop, but it only achieves 2.4 kbps raw data speeds – essentially dial-up modem speed ts2.tech. In practical terms, that’s enough to perhaps send a GPS coordinate or a brief text email; don’t expect to browse the web. (Iridium does offer higher-speed data services called Iridium Certus, but those require different terminals.) The 9555 also features an integrated speakerphone for hands-free use, and an internal phonebook for contacts. Notably missing are a GPS receiver and an SOS emergency button – features that some other sat phones include. So while you can call for help on the 9555, it won’t automatically transmit your location. Users who need that functionality might opt for the Iridium Extreme or other devices with GPS. Another absent feature is any kind of cellular or Bluetooth connectivity – the 9555 cannot act as a cell phone or pair with headsets (wired earpiece is the only option for privacy) ts2.tech. It’s very much a standalone, purpose-built satellite handset.
Battery life: The 9555 comes with a rechargeable Li-ion battery rated for up to 4 hours of talk time and ~30 hours standby iridium.com iridium.com. In practice, users often carry a spare battery if they’ll be away from power for long, since 4 hours of cumulative talk can be consumed quickly during an expedition (for instance, a few long check-in calls). Standby time of ~30 hours means if you leave the phone on (waiting for incoming calls), you’ll need to charge or swap battery every day or two. Compared to its competitors, the 9555’s battery life is on the shorter side – for example, the Inmarsat IsatPhone 2 can last up to 160 hours on standby ts2.tech ts2.tech, a major selling point for that device. Iridium prioritized a more compact size for the 9555, at the expense of a smaller battery. As GearJunkie’s testers put it, “the 9555 is convenient because of its robust build and compact size, even at the sacrifice of battery life. With just 4 hours of talk time, a second battery is a must” gearjunkie.com. The phone charges via an AC adapter (and supports 12V car chargers); one advantage is that Iridium batteries endure cold weather reasonably well (operative down to -10 °C) iridium.com, whereas some smartphones might shut off in extreme cold.
Cost of ownership: Buying an Iridium 9555 new will set you back around $1,000 (give or take a hundred). At the time of writing, it’s listed about $1,129 on some sites ts2.tech ts2.tech, though shopping around may find deals closer to $900. If you commit to a service plan, some providers heavily discount the handset – e.g. SatellitePhoneStore was offering the 9555 for $699 with a 2-year airtime contract satellitephonestore.com. Rental is also an option for short-term needs (roughly $50-$100/week from various outfitters). Using the phone requires a service plan or prepaid SIM. Iridium service is typically the priciest of the sat providers, reflecting its global coverage. Common plans might be, for instance, $65/month for 10 minutes included gearjunkie.com, or $150/month for 150 minutes. Prepaid vouchers are popular for Iridium – e.g. 500 minutes valid 12 months for around $700. The good news is that incoming calls and texts are free to the Iridium user (the caller pays a high rate or uses a special access number) gearjunkie.com. This means you can conserve minutes by having family or colleagues call you when possible. Also, unlike cell phones, you’re not charged for incoming minutes on most sat plans. Outgoing SMS from the 9555 count against your plan (or cost about ~$0.50 each if pay-as-you-go). It’s worth noting that Iridium’s prices, while high, have come down over the years – “that’s half the cost of what it was just a few years ago” for entry-level plans, one reviewer notes gearjunkie.com.
Pros of Iridium 9555: Foremost, coverage and reliability. The 9555 can get a signal virtually anywhere on Earth, which is a huge advantage if your travels or operations have no geographic bounds. It doesn’t matter if you’re at the North Pole or deep in the Amazon – as long as you have a clear view of the sky, you can reach the Iridium network ts2.tech ts2.tech. The Iridium network’s cross-linked satellites reduce the chances of a dropped call, since one satellite can hand off to another overhead in real time. Also, LEO satellites mean low latency (voice delay ~0.3 seconds, barely noticeable) and typically strong signal even if you’re moving. Voice quality on Iridium is generally good; while codec compression means it’s not HD voice, it’s clear enough for critical communications. Another pro is the ruggedness of the 9555 – it’s built to take a beating in outdoor environments ts2.tech. Many users have noted their 9555 survived years of use in the field. It’s also relatively compact and easy to carry compared to some competitors (the antenna retracts, making it more pocketable than the older Iridium models) ts2.tech. Finally, Iridium offers accessory compatibility – the 9555 supports external antennas and docking stations. For example, you can connect it to a car or boat antenna for improved reception, or use a data dock to integrate with a laptop or send/receive faxes (if anyone still does that). This flexibility makes it popular in maritime and aviation backups.
Cons of Iridium 9555: The main downsides are cost and feature limitations. It’s one of the most expensive sat phones to buy and operate, which can be overkill if you don’t truly need global coverage. If your adventures are confined to, say, the continental US or Europe, a cheaper regional satellite phone (or even newer satellite messengers) might suffice. The 9555’s omission of an emergency SOS button and GPS is a negative in the safety department ts2.tech ts2.tech. Competitors like the IsatPhone 2 and Thuraya XT-PRO include GPS and one-press SOS functionality – features very useful for lone travelers or remote workers. With the 9555, you’d need a separate GPS device to know your coordinates and verbally relay them in an emergency. Another con is the lack of waterproofing – while durable, the device isn’t officially water-resistant. If you drop it in a river, it’s probably game over. Even heavy rain could potentially get into the battery compartment (some users mitigate this by using a waterproof pouch or case in wet conditions). The shorter battery life is also a drawback if you need multi-day standby power ts2.tech ts2.tech – you’ll be charging it more often or carrying spares, which is less convenient off-grid. Finally, one could argue the user interface is dated: a small monochrome screen and T9 text input is a throwback for anyone used to modern smartphones. It gets the job done for dialing and basic texting, but it’s not a device you’d use for anything beyond essential communication.
Use cases: Who is the Iridium 9555 best for in 2025? It remains a top choice for expedition leaders, extreme adventurers, and maritime users who need an always-working lifeline. For example, mountaineering teams often carry a 9555 for anywhere-on-Earth emergency comms. Ocean sailors, especially those venturing near polar seas or remote oceans, rely on Iridium because competitors might not have coverage in those areas ts2.tech ts2.tech. Disaster response organizations and militaries also like the 9555 as a backup: you can cache a few 9555 handsets in emergency kits, and even years later they should still function (with charged batteries and active SIMs) to coordinate relief efforts. In short, the Iridium 9555 is for users who absolutely require global reach and proven durability over any bells and whistles. As one industry summary put it, the 9555 is a “grab-and-go sat phone that just works for calls and texts” when you need it ts2.tech ts2.tech.
(Note: Iridium’s lineup also includes the Iridium Extreme (9575), which is essentially a souped-up sibling to the 9555. The Extreme has the same core calling/texting ability and global coverage, but adds built-in GPS with an SOS button, a more rugged IP65 housing, and supports some push-to-talk features. It usually costs a few hundred dollars more than the 9555 ts2.tech. If you foresee needing those safety features, you might consider the Extreme. For many users, though, the 9555 hits a sweet spot of slightly lower cost while still leveraging the exact same network.)
Inmarsat IsatPhone 2 – Near-Global Coverage with Best Battery Life
If you don’t need polar coverage, Inmarsat’s IsatPhone 2 is arguably the Iridium 9555’s closest competitor. Launched in 2014 as a second-gen device, the IsatPhone 2 has earned a reputation as the “battery champ” of satellite phones, and a very solid all-around performer for voice and text. It operates on the Inmarsat network, which runs geostationary (GEO) satellites high above the equator. Inmarsat has been a key player in satcom since the 1970s (originally for maritime safety), and its current constellation (as of 2025) includes three operational I-4 satellites and newer I-6 birds coming online, covering virtually the entire globe except the extreme polar caps ts2.tech ts2.tech. Coverage extends roughly between ~82° N and 82° S latitudes – that’s about 99% of the world’s inhabited surface ts2.tech ts2.tech. So unless you are going to the North Pole or Antarctica, an IsatPhone 2 will work in any continent or ocean. One quirk: because the satellites sit above the equator at 35,000 km, you need a relatively clear view southward (if you’re in the Northern Hemisphere) or northward (in the Southern Hemisphere) to connect. The phone’s antenna is a sturdy fold-out boom that you tip up and toward the satellite’s general direction. The benefit of GEO satellites is that once you’re connected, the satellite stays fixed relative to you – there’s no moving satellite handoff to worry about. This means calls on Inmarsat, once established, tend to be very stable (no periodic drop-outs). The downside is the ~1 second voice delay inherent to GEO distance – you’ll notice a slight lag in conversation ts2.tech ts2.tech. Many users get used to it, but it can make you inadvertently talk over the other person until you find a rhythm.
Hardware and design: The IsatPhone 2 is a larger, heavier handset than the Iridium 9555. It measures about 6.7 × 2.1 × 1.1 in and weighs 11.2 oz (318 g) including its massive battery ts2.tech ts2.tech. It has a prominent cylindrical antenna that swivels out from the top. The build is very robust: IP65-rated casing, meaning it’s dust-tight and protected against water jets ts2.tech ts2.tech. You can use it in a rainstorm without worry, and it’s designed to survive drops (Inmarsat advertises it as “a tough phone for a tough world”). The interface includes a transflective color screen (easy to read in sunlight) and a physical keypad. Like Iridium, it operates in extreme temperatures from -20 °C to +55 °C ts2.tech, suitable for desert or arctic use (just outside polar sat range).
Standout feature – Battery life: The killer feature of the IsatPhone 2 is its battery longevity. On a full charge, it boasts up to 8 hours of talk time, and an astounding 160 hours (6–7 days) of standby ts2.tech ts2.tech. This is the longest among all handheld satellite phones. In practice, that means you can leave the phone powered on, waiting for a call or SOS alert, for nearly a week – invaluable if you are in the field expecting someone to reach you, or if you want to keep the phone on to use its GPS tracking. By comparison, Iridium phones need daily charging if left on continuously. This battery life advantage is frequently cited by expedition users who might not have frequent charging opportunities. Reviewers have noted you can “leave it on for days” and still have juice – a major plus for base camps or long road trips ts2.tech ts2.tech.
Features: The IsatPhone 2 is feature-rich relative to the Iridium 9555. It has a built-in GPS receiver, and a one-touch SOS button concealed under a protective cap on the top of the handset ts2.tech ts2.tech. When configured, pressing this SOS button will send your GPS coordinates and distress message to a preset emergency service (often Inmarsat partners with GEOS, an international rescue coordination center) ts2.tech ts2.tech. This gives peace of mind to solo adventurers – you have a direct lifeline for rescue. The phone also supports tracking: you can set it to transmit your GPS coordinates at regular intervals to someone monitoring, which is useful for expeditions or convoys ts2.tech ts2.tech. In terms of communication, the IsatPhone 2 handles voice calls and SMS. It can send small emails (again, typically via an email-to-SMS gateway). Data capability is limited to the same 2.4 kbps narrowband as Iridium – meaning it’s not really for internet use, more for text-based data or weather reports. The device’s menu and interface are straightforward, with a bit more modern look than Iridium’s – the color screen and logical menus make it fairly user-friendly. It even has an alert button that can ring loudly or flash to notify of incoming calls when the antenna is stowed (so you can keep it folded but still not miss a call – a thoughtful feature for power saving) ts2.tech ts2.tech. Starting a call on Inmarsat might take a bit longer to register with the network (the phone often quotes ~45 seconds for registration) ts2.tech, but once connected, it stays locked on.
Performance: Users generally praise the IsatPhone 2’s voice clarity. Because Inmarsat uses high-fidelity voice codecs and a stable connection, calls sound very clear, often indistinguishable from a regular mobile call except for the slight delay ts2.tech ts2.tech. In open areas with a clear view of the sky, dropped calls are rare. However, because the satellites sit on the equator, if you’re at higher latitudes (e.g. Alaska, Patagonia) or in a city with tall buildings to your south, getting a lock can be trickier – the satellite will be low on your horizon. Field reports have noted that in polar-adjacent areas or deep valleys, the IsatPhone sometimes struggled to connect until the user moved to a higher vantage point gearjunkie.com gearjunkie.com. In contrast, Iridium’s constantly moving satellites might sometimes find an angle through terrain gaps. So, terrain and latitude are factors: in wide-open flat terrain, Inmarsat works brilliantly; in a narrow canyon or very high latitude (80°+), Iridium has the edge.
Price & plans: The IsatPhone 2 is generally cheaper than the Iridium 9555. As of 2025, the handset sells for about $750-$900 new ts2.tech ts2.tech. We saw listings around $799 at major retailers. It’s also often bundled free or for ~$0 with certain annual plans (some providers will give you the phone if you prepay a year of service). Speaking of service, Inmarsat airtime tends to be a bit more affordable than Iridium. Prepaid SIMs are common – e.g. 100 units (minutes) for ~$130, etc. Inmarsat’s per-minute voice cost is similar or slightly less than Iridium’s (around $0.80 to $1.00 on many plans), and they offer things like roll-over minutes and regional plans. If you only need coverage within a single ocean region, you can sometimes save cost with an Inmarsat plan targeted to that area. Overall, for a traveler not going to polar regions, the IsatPhone 2 often delivers more value for the money – lower device cost, and enough coverage for 99% of use cases. Analysts note that “Inmarsat service plans often offer good value for regional use” compared to Iridium ts2.tech ts2.tech.
Pros of IsatPhone 2: To summarize the upsides: exceptional battery life, excellent voice quality, dedicated safety features (SOS/GPS) ts2.tech ts2.tech, rugged build (IP65) ts2.tech ts2.tech, and a lower price point. It provides near-global coverage that suffices for the vast majority of travelers – covering all continents and oceans except the poles ts2.tech ts2.tech. The long standby means it’s great for emergency standby – e.g. leaving it in your storm shelter or vehicle glovebox turned on during a trip, confident it will last. The SOS button is a key advantage for lone workers or explorers; you can trigger a rescue without navigating phone menus under duress. Also, the IsatPhone 2 is user-friendly; reviewers often mention its menu and interface are easy to pick up, which is important if a non-techie might need to use it in an emergency.
Cons of IsatPhone 2: The main limitation is no polar coverage – if you are one of the few going above ~80° latitude, this phone won’t work for you ts2.tech. Another con is the need for a clear view toward the satellite: in environments like mountains or high latitudes, the Inmarsat satellite sits low on the horizon which can make connecting harder ts2.tech ts2.tech. You might need to find a clearing or ridge with view of the equator. The ~1 second voice delay can be a slight nuisance for conversational flow ts2.tech ts2.tech (though Globalstar and Iridium have virtually no delay). For data, it shares the same slow 2.4 kbps limit – fine for texts/email, not for any modern internet use ts2.tech. Physically, the IsatPhone 2 is bulkier – it’s a bigger device to carry, and you have to deploy the antenna each time (which is easy, but it does double the length of the unit when open) ts2.tech. Finally, while rugged, it’s not completely waterproof; IP65 means it can handle rain but not submersion. Overall, these cons are fairly minor for most users, but they underscore that the IsatPhone 2 is optimized for certain scenarios (stationary or slow-moving use in open areas, outside extreme latitudes).
Use cases: The IsatPhone 2 shines for users like sailors, overland adventurers, and remote fieldworkers who want a reliable sat phone but don’t plan on venturing into polar regions. It’s very popular in the maritime community – for instance, a sailor in mid-ocean (below 70°N/S) can use an IsatPhone to call home or download a weather forecast, enjoying long battery life and stable connections. Many sailing yachts carry one for emergency backup, as it can stay on to receive an incoming distress call or coordination message (something an Iridium might struggle to do for days on end without recharging). Humanitarian NGOs and disaster response teams often deploy IsatPhone 2 units because they are cost-effective and robust for places like sub-Saharan Africa or Asia where they work reliably ts2.tech. In those scenarios, the free incoming call feature (like Iridium, callers can reach you without costing your minutes) and long standby are very helpful. Even for casual travelers or expeditions, if your journey is, say, a trek to Everest Base Camp or a Sahara crossing – the IsatPhone 2 is a great companion: you get confidence of connectivity, an SOS option, and you likely won’t need to charge it the entire trip.
In summary, the Inmarsat IsatPhone 2 is a formidable alternative to the Iridium 9555. It doesn’t have global polar reach, but it makes up for that with superb battery life and a bit lower costs, which can be a deciding factor for many. As one tester put it, “when it comes to getting into a quality satellite phone without busting the bank on the entire expedition, the IsatPhone 2 is our choice.” gearjunkie.com gearjunkie.com
Thuraya Satellite Phones – Regional Solutions with High-Tech Features
For those who travel primarily in Europe, Africa, the Middle East, or Asia, Thuraya offers a range of satellite phones that can be an attractive option. Thuraya’s network consists of two geostationary satellites (positioned to cover EMEA and large parts of Asia/Australia), and it focuses on those regions with regional service. Thuraya phones will not work in North or South America – they have no satellite coverage over the Western Hemisphere ts2.tech ts2.tech. But within its coverage footprint (approximately 160 countries), Thuraya provides reliable communications and often at a lower cost per minute than Iridium or Inmarsat ts2.tech ts2.tech. In fact, GearJunkie’s experts note that if your travel is only in Thuraya’s region, it can be a great option, precisely because you’re not paying for global capabilities you don’t need gearjunkie.com.
Thuraya currently markets a few different handsets to cater to various user needs. We’ll highlight three: the Thuraya XT-LITE (budget-friendly basic phone), the Thuraya XT-PRO (rugged professional-grade phone), and the Thuraya X5-Touch (a satellite smartphone). All three share the same core network coverage and voice/SMS capability – the differences are in features, durability, and price.
Thuraya XT-LITE – Budget Basics
The XT-LITE is Thuraya’s entry-level sat phone, designed to be no-frills and affordable. It’s actually one of the cheapest satellite phones on the market, with a typical price around $600–$800 new ts2.tech ts2.tech. For that price, it delivers dependable voice calling and texting across the Thuraya network. The XT-LITE’s appeal is in its simplicity and battery life: it manages about 6 hours of talk time and 80 hours standby on a charge ts2.tech ts2.tech – not as long as the IsatPhone 2, but still very good, especially given its small size. Indeed, the XT-LITE is lightweight and compact: ~5.0 × 2.1 × 1.1 in and just 186 g (6.5 oz) ts2.tech ts2.tech, making it one of the lightest sat phones available. It has an internal omnidirectional antenna design that allows for “walk-and-talk” use, meaning you don’t have to meticulously point it at the satellite while moving ts2.tech ts2.tech.
The trade-off for the low cost is that the XT-LITE is basic in features: it does not have GPS, no SOS button, no email or data capabilities beyond SMS ts2.tech ts2.tech. It’s essentially a satellite flip-phone (though the antenna, not the body, is what flips out). This is fine for users who only need the occasional call or text in remote areas. It’s also reasonably rugged for its class – there’s no official IP rating published, but it’s built to handle outdoor use, splashes, dust, and some drops ts2.tech ts2.tech. Just don’t expect it to be as indestructible as a high-end model; think of it as durable enough for camping or fieldwork, but perhaps not full military spec. One neat feature: the XT-LITE will ring/notify incoming calls even if the antenna is stowed, as long as the phone is on and has some signal ts2.tech ts2.tech. This means you can keep it packed away but not miss calls – a convenience that many sat phones lack (usually antenna must be out to receive). Thuraya’s calling rates are relatively low, often costing a fraction of Iridium’s per minute. That, combined with the device price, makes the XT-LITE + a Thuraya plan an extremely budget-friendly satellite phone solution ts2.tech ts2.tech for those in its coverage area.
Pros (XT-LITE): Affordability is number one – it’s one of the least expensive ways to get a satellite phone ts2.tech ts2.tech. Not only is the device cheap, but the airtime plans are known to be cheaper (e.g. you can get per-minute costs well under $1, especially within certain regions) ts2.tech ts2.tech. The XT-LITE also offers good battery life (6h talk is plenty for normal use, and 80h standby means you can leave it on for several days) ts2.tech ts2.tech. It’s light and pocketable, which travelers appreciate – at 186 g you’ll hardly notice it in your pack ts2.tech. The interface is simple and user-friendly, closer to an old Nokia phone – easy for anyone to pick up. And the omni-directional antenna design gives some leeway in maintaining a connection while you’re on the move ts2.tech ts2.tech (you still need line-of-sight generally, but you won’t drop the call if you shuffle around a bit). For those operating purely in Thuraya’s region, it provides all the essential sat phone needs without the premium cost of a global phone.
Cons (XT-LITE): The obvious con is limited coverage – if you take this phone outside of the EMEA/Asia/Aus footprint, it’s a paperweight ts2.tech ts2.tech. So it’s not suitable for round-the-world travel or transoceanic adventures beyond its zone. It also lacks any SOS or GPS function – a downside for emergency preparedness ts2.tech ts2.tech. You’d need to know your location some other way if calling for rescue. It’s also not highly ruggedized; while fine in a drizzle, it’s not waterproof or MIL-spec ts2.tech ts2.tech. Heavy rain or submersion could damage it. Data capability is nearly nonexistent – Thuraya does have a GmPRS data service up to ~60 kbps on some devices, but the XT-LITE isn’t really meant for data use (at most, it might send a very slow GmPRS connection with a laptop, but that’s not advertised strongly). So it’s voice/SMS only, essentially ts2.tech. And like Inmarsat, Thuraya uses GEO satellites, so you need to orient toward the satellite’s direction; if you’re at the edge of coverage (say, far East Asia or South Africa), the satellite will be low on your horizon which can affect signal ts2.tech ts2.tech. Urban environments can block Thuraya signals if tall structures are in the way. Basically, you need open sky more or less, similar to other sat phones (perhaps a bit more directional sensitivity needed than Iridium’s network).
Who should consider the XT-LITE? It’s ideal for cost-conscious users in Thuraya’s regions. Examples: an NGO worker in rural Africa who needs a phone for weekly check-ins, a trekker in the Himalayas who wants an emergency calling option, or even a small business that operates in the Middle East oilfields and needs staff to have backup comms. It’s also popular as an emergency phone for residents of remote areas (e.g. someone in a village in North Africa without reliable cellular might keep a Thuraya for backup). Because it’s inexpensive, people who wouldn’t splurge on a sat phone might choose this model “just in case.” If your travels will never take you to the Americas, the XT-LITE can save you a lot of money while still keeping you connected off-grid.
Thuraya XT-PRO – Rugged and Feature-Rich
Moving up the ladder, the Thuraya XT-PRO is the premium handheld in Thuraya’s lineup (aside from the smartphone). It’s designed for professional users who need extra durability and features. Physically, the XT-PRO is a bit larger than the XT-LITE, with a high-capacity battery that gives up to 9 hours talk and 100 hours standby ts2.tech ts2.tech – one of the best in class, rivaling the IsatPhone 2’s longevity. Thuraya actually boasted that the XT-PRO had the longest talk time of any satellite phone at the time of its launch ts2.tech ts2.tech. The phone weighs ~222 g (7.8 oz) ts2.tech ts2.tech, and its form factor is still quite hand-friendly (around 5.4″ tall). Importantly, it’s tougher: built to IP55 standards for dust and water resistance, with a Gorilla Glass display for scratch protection and sunlight readability ts2.tech ts2.tech. It can handle rain and dusty conditions, although IP55 is not fully waterproof (it can handle jets of water but not submersion).
Feature-wise, the XT-PRO adds GPS (and GLONASS, BeiDou) capability – it can access multiple navigation satellite systems, giving highly accurate position data ts2.tech ts2.tech. Users can view their coordinates on-screen and even send their location via SMS easily. There’s also a programmable SOS button on the device (in line with other high-end sat phones) that you can configure to call or text a predefined emergency contact ts2.tech ts2.tech. This is an important safety addition over the XT-LITE. The XT-PRO supports Thuraya’s GmPRS data service, meaning you can hook it to a laptop and get roughly ~60 kbps down / 15 kbps up for data ts2.tech. That’s still very slow by any modern standard, but notably faster than Iridium’s 2.4 kbps – enough to send emails or small files more comfortably. The device can also do basic tracking and waypoint sending like the IsatPhone (though it may require use of the phone’s menus to send periodic location SMS). There was also a variant called XT-PRO DUAL which includes a GSM SIM slot, allowing it to act as a normal cell phone when in range of terrestrial networks, then switch to satellite when off-grid ts2.tech ts2.tech. The standard XT-PRO doesn’t have cell capability, but is otherwise similar. In any case, the presence of a dual-mode option underscores Thuraya’s attempt to integrate with regular phone usage.
Pros (XT-PRO): The battery life stands out – 9 hours talk is excellent for power users who may be on long calls or unable to charge frequently ts2.tech ts2.tech. The navigation features (GPS/GLONASS/BeiDou) are a big plus for anyone who needs precise location or wants to use the phone for basic navigation tasks ts2.tech ts2.tech. It basically removes the need to carry a separate handheld GPS in many cases. The rugged build (Gorilla Glass and IP55) means it can handle rough expeditions and outdoor worksites ts2.tech ts2.tech. Having an SOS button brings peace of mind in emergencies – it’s a vital feature for lone field workers or explorers ts2.tech ts2.tech. The data capability, while limited, is still better than nothing – if you need to send a batch of emails or weather updates, the 60 kbps link can do it much faster than a 2.4 kbps Iridium link ts2.tech ts2.tech. Also, the XT-PRO’s screen and interface are improved over the LITE – the Gorilla Glass, anti-glare screen is easier to read in bright sun (deserts, high seas) ts2.tech ts2.tech. And for those who want it, the DUAL version’s ability to have one device for cell and sat is quite convenient – you could carry one phone and use local SIMs when in town, then hop to satellite mode when out in the wild ts2.tech ts2.tech.
Cons (XT-PRO): Despite improvements, it shares coverage limitations with all Thuraya devices – it’s useless outside its regional satellite footprint ts2.tech ts2.tech. So any travel to the Americas or far oceans will require a different solution. The cost is higher – roughly $950 for the XT-PRO, and over $1,300 for the dual-mode version ts2.tech. While still cheaper than an Iridium Extreme, it’s notably pricier than the XT-LITE, so budget users might find it overkill ts2.tech ts2.tech. The XT-PRO is slightly bulkier than the LITE (though still not bad; the extra ~36 g is a small trade for double the battery life) ts2.tech ts2.tech. The user interface, while solid, is still a traditional phone OS – not a smartphone, no touch screen, etc. ts2.tech ts2.tech. So it won’t have modern apps (for that, see X5-Touch). Another consideration: Thuraya’s ecosystem (accessories, support) is a bit limited in the Western Hemisphere since Thuraya isn’t used there. If you’re in Europe/ME, it’s fine, but in the US for instance, finding Thuraya accessories or support requires ordering from abroad. And though Thuraya’s data speed is better than Iridium’s, it’s still very slow relative to any broadband – don’t imagine doing anything beyond text-based internet tasks ts2.tech. It’s for essential data only.
Use cases (XT-PRO): The XT-PRO is aimed at more demanding users in Thuraya’s coverage areas. Think of professionals like geologists, researchers, or journalists operating across Africa/Asia who need a reliable sat phone with navigation aids. It’s also great for adventure travelers who traverse deserts, mountains or sail in regions like the Mediterranean or Indian Ocean – they get the benefit of long battery life and an SOS safety net. For example, an expedition crossing the Sahara might choose XT-PRO so they can get location fixes (using the multi-GNSS) and have hours of talk time for daily check-ins. Maritime users in coverage (like Red Sea or coastal Asia) also enjoy the long battery and water resistance. The XT-PRO basically takes the worry out of battery and the environment – you know it will last and endure. If someone needs a sat phone plus navigation in one, the XT-PRO delivers that combination. It’s also a bit of a status upgrade from the LITE for government or NGO outfits equipping their teams – providing extra assurance with the SOS and toughness.
Thuraya X5-Touch – The Satellite Smartphone
Lastly, Thuraya has a unique device in this space: the Thuraya X5-Touch, billed as “the world’s smartest satellite phone.” Unlike all the others which have proprietary simple OSes, the X5-Touch is an Android-based smartphone that can connect to both cellular and satellite networks ts2.tech ts2.tech. Essentially, it’s a rugged Android phone (running Android 7.1 in its current iteration) with a 5.2-inch touchscreen, dual SIM slots (one for satellite SIM, one for GSM/LTE) ts2.tech ts2.tech. It weighs about 262 g, similar in heft to the IsatPhone but in a more streamlined form factor ts2.tech. The X5-Touch is IP67 and MIL-STD-810G certified – meaning it’s dustproof, can survive 30 minutes under 1m of water, and is shock-proof to military drop test standards ts2.tech. It has a big battery (around 3,800 mAh) yielding up to 11 hours talk and 100 hours standby in satellite mode ts2.tech, which is excellent. The device supports satellite voice and SMS, and on the cellular side it’s like a normal smartphone with 4G/LTE where available. For data, it can do GmPRS satellite data ~60 kbps (like the XT-PRO) and of course much higher speeds on cellular (LTE). Being Android, it can run apps, take photos, use GPS (it has GPS/GLONASS/BeiDou), etc. In essence, the X5-Touch is aimed at users who want one converged device for both everyday and off-grid use.
The X5-Touch is quite pricey – typically around $1,300–$1,700 ts2.tech. That price and its limited regional coverage mean it’s a niche choice. But it’s worth mentioning as part of the 9555’s competitive landscape because it represents a trend toward convergence: bridging sat phones with modern smartphone capabilities. For someone stationed in, say, the Middle East who needs robust connectivity: they could use the X5 on local networks day-to-day and still have always-on satellite standby if they leave coverage or during emergencies.
Pros (X5-Touch): It offers unparalleled flexibility by combining a smartphone and satellite phone ts2.tech ts2.tech. You don’t need to carry two devices. You have access to all Android apps (maps, messaging, etc.) which can be useful offline too. It has the best display and user interface of any satellite phone (since it’s basically a smartphone). Ruggedness is top-notch (IP67 is better than most other sat phones) ts2.tech, so it’s built for harsh environments. The battery life is long considering the large screen. And that dual-SIM capability is unique – you could have your normal number and satellite number active together (the phone will alert you to cellular vs satellite usage). For data, while satellite data is slow, you can do more with an Android device – e.g. compose emails, use lightweight apps, and then send when connected.
Cons (X5-Touch): The cost is very high, making it likely only for organizations or well-heeled users who truly need its feature set. It’s still bound by Thuraya’s coverage limits, so no use in the Americas or polar regions, which is a big drawback for a device that expensive. Some might argue the Android version (7.1 Nougat) is older, and app support might wane – but core functions will still work. The complexity of a smartphone also means more things can potentially go wrong (crashes, etc.) compared to simpler sat phones. Also, the phone is a bit bulkier than non-smart sat phones, and one has to manage the device like a smartphone (charging, updates, etc.). For ultra-rugged expeditions, some prefer the simplicity of a basic sat phone that has nothing else to drain the battery or break. So the X5-Touch occupies a special niche: tech-savvy professionals in Thuraya regions who want the convenience of one rugged device for everything.
In summary, Thuraya’s lineup provides strong options if your operations are within their coverage zones. The XT-LITE gives you connectivity at minimal cost. The XT-PRO adds reliability and safety features on par with Inmarsat/Iridium offerings (except coverage), and the X5-Touch points to the future of sat phones merging with smartphones. The main thing to remember is Thuraya is regional: fantastic if you’re in its part of the world, irrelevant if you’re not. Many experienced travelers actually carry a Thuraya phone and an Iridium or Inmarsat phone on global trips – using Thuraya where available (cheaper rates) and falling back to Iridium elsewhere. For strictly EMEA/Asia users though, Thuraya can be a real money-saver without sacrificing connectivity where it matters.
Globalstar GSP-1700 – Affordable Voice for Select Regions
The last major player to compare is Globalstar. Globalstar’s flagship (and only) handheld is the GSP-1700, a device originally introduced in the late 2000s – around the same era as Iridium 9555 – and still in use today ts2.tech ts2.tech. If Iridium’s claim to fame is global reach, Globalstar’s is call clarity and low cost, albeit with limited coverage. The Globalstar network uses a constellation of LEO satellites (48 satellites) that operate differently from Iridium’s – they have no cross-links and connect via roughly 24 ground stations scattered around the world ts2.tech ts2.tech. In simpler terms, a Globalstar satellite must be in view of both your phone and one of their ground gateways to route your call. This design initially caused some service issues (if no gateway in range, no service), but where there is coverage, it yields very clear voice with minimal delay – often better call quality than other sat phones ts2.tech ts2.tech. In fact, many users comment that talking on a Globalstar feels like a normal cell phone call, with virtually no lag and crisp audio ts2.tech ts2.tech. This is a big plus for conversations where timing and quality matter (e.g. coordinating a response effort).
Coverage: Globalstar’s footprint is essentially regional. They cover most of the continental United States, Canada, Alaska, the Caribbean, and coastal areas of South America; also much of Europe, parts of North Africa, and portions of Asia (like Japan, and recently some expansion in South/Southeast Asia) ts2.tech ts2.tech. However, there are large gaps: virtually no coverage in mid-ocean (once you sail a few hundred miles off coast, you lose it), none in big chunks of Africa and Central Asia, and nothing in high polar regions ts2.tech ts2.tech. They advertise “over 120 countries, covering ~99% of the world’s population” ts2.tech – the caveat being that population centers are covered, but vast uninhabited areas (like open ocean, Antarctica, etc.) are not. So if you stick to populated parts of the Americas, Europe, and certain parts of Asia/Australia, Globalstar can work well. If you wander outside those, you may have zero signal. This inherent limitation makes Globalstar unsuitable for global expeditions, but potentially very suitable for regional adventurers (e.g. North American hikers, hunters, etc.).
Device and features: The GSP-1700 is a small, lightweight phone: about 5.3 × 2.2 × 1.5 inches and only 7.1 oz ts2.tech ts2.tech. It has a stubby fold-out antenna. The design is a bit dated (it even came in multiple colors like a retro cellphone – you could get it in orange, silver, etc.), but it’s quite pocketable. Battery life is roughly 4 hours talk, 36 hours standby ts2.tech ts2.tech – similar talk time to Iridium, but better standby. The phone has a color LCD interface, a contacts list, and supports two-way SMS and even short emails (by sending text to an email gateway) ts2.tech ts2.tech. Notably, it has an integrated GPS receiver, and you can see your coordinates on-screen or send your location in a message ts2.tech ts2.tech. However, unlike newer phones, it does not have a dedicated SOS button. If you need help, you’d dial emergency services or a predefined contact manually. One advantage of Globalstar is that their phones can have a normal telephone number (often a U.S. number), whereas Iridium and Inmarsat use special country codes that can be costly for others to dial. With Globalstar, your sat phone can have, say, a +1 (USA) number – making it easy and cheap for people to call you locally gearjunkie.com gearjunkie.com. This is great because friends/family or colleagues won’t be deterred by high costs or strange dialing procedures – it’s like calling a regular phone for them (the calls route through Globalstar’s terrestrial system).
A big technical note: Because Globalstar satellites don’t hand off seamlessly (no cross-links), there used to be times when no satellite was in view of a gateway, causing call outages. But the second-gen satellites largely solved the early issues – still, if you’re on the fringe of coverage, you might experience times of no service. Also, moving quickly across regions (like flying or fast driving out of one gateway’s footprint to another) can drop calls.
Data: The GSP-1700 can be used as a modem with higher data throughput than Iridium: about 9.6 kbps uncompressed, ~20–28 kbps with compression ts2.tech ts2.tech. This might sound laughable, but in practice, sending a small email that takes 1 minute on Iridium might take only 15 seconds on Globalstar – a noticeable improvement. It’s still not for web browsing beyond perhaps loading a very basic text page, but it’s the fastest of the handheld satellite phones for data ts2.tech ts2.tech.
Cost advantage: The reason many consider Globalstar is the cost. The GSP-1700 handset has often been sold for $500 or less ts2.tech ts2.tech, and at times even given for free during promotions ts2.tech ts2.tech. As of 2025, since the device is older and not directly sold by Globalstar anymore, you typically find it through resellers or as refurbished units in the few-hundred-dollar range ts2.tech. The real kicker is the service plans: Globalstar offers some extremely competitive plans, including unlimited talk options. For example, there have been plans around $150/month for unlimited calls, or $100/month for a very large bucket of minutes gearjunkie.com gearjunkie.com. Per-minute rates can be as low as a few tens of cents if you choose larger packages, significantly undercutting Iridium/Inmarsat costs. This makes Globalstar attractive to users who need to talk a lot on their sat phone – e.g. remote workers checking in daily, or people who live off-grid but within coverage. Additionally, because of the local number feature, callers don’t incur huge fees to reach you, and you can integrate the sat phone into normal calling rotations (some small businesses in rural Alaska, for example, use Globalstar phones as a primary line when out of cellular range, since it’s economically feasible with unlimited plans).
Pros of Globalstar GSP-1700: The stand-out pro is voice quality and low latency. Calls sound very clear and natural – testers often note it’s the closest to a regular phone conversation you can get via satellite ts2.tech ts2.tech. If you hate the typical sat phone delay or tinny sound, Globalstar is refreshing. Affordable hardware and service is another huge plus ts2.tech ts2.tech. For someone on a budget, being able to get a sat phone capability for a few hundred bucks is a big deal. The unlimited plans or cheap minutes mean you can actually use the phone more freely, whereas with Iridium you might think twice because each minute costs $$$. The GSP-1700 is light and compact, easy to stow and carry ts2.tech. It has fastest data of the handhelds (albeit still slow) which helps for quick texts/emails ts2.tech ts2.tech. Also, through the gateway infrastructure, you get that local number convenience ts2.tech ts2.tech – making communications simpler for everyone. Another subtle pro: since the network doesn’t cover the whole globe, it’s inherently focused on populated areas; Globalstar’s marketing points out they cover “99% of the world’s population” ts2.tech. If your adventures keep you within those populated zones, you may rarely notice any difference from a global phone, except in your wallet.
Cons of Globalstar GSP-1700: The glaring con is limited coverage. It only covers about 80% of Earth’s surface (and none of the poles) ts2.tech ts2.tech. If you wander outside the ~120 countries covered, you simply won’t have service. For truly remote expeditions (like deep ocean sailing, polar treks, or crossing central Africa), Globalstar is not viable ts2.tech ts2.tech. Also, because of reliance on ground stations, if one of those gateways has an outage or you’re at the edge of its range, you might drop calls or have no signal despite a satellite overhead ts2.tech ts2.tech. In other words, the network can be a bit more fragile in fringe scenarios (though perfectly fine in core areas). The technology is older – the GSP-1700 is a dated device with no modern amenities (no SOS button, no Bluetooth, uses mini-USB, etc.) ts2.tech ts2.tech. It’s functional, but not fancy. Globalstar hasn’t released a new handheld in many years, which raises questions about future support, but the company has stated it will continue supporting the service for the foreseeable future ts2.tech ts2.tech, especially given their partnership with Apple (they have revenue to maintain their satellites). Another con: no built-in SOS means you must dial emergency numbers manually and convey your GPS verbally or via text – a bit slower in crises ts2.tech. Also, performance can suffer at the edges of coverage; if you’re in a marginal area, you may experience more dropped calls or shorter available talk windows when satellites pass by ts2.tech ts2.tech. Historically, Globalstar had a rough patch around 2007–2010 where their old satellites’ duplex channels failed – they’ve fixed that with new satellites, but it left some wariness among veteran users. Finally, uncertainty about future handset models: if this device eventually isn’t supported or breaks, there’s no “new Globalstar phone” (as of 2025) to upgrade to – you’d likely have to find another GSP-1700 or switch systems.
Use cases: The Globalstar GSP-1700 is excellent for North American outdoors enthusiasts (or similar in covered regions) who want an emergency phone or a way to stay in touch, but don’t need global reach. For example, backcountry hikers in the Rocky Mountains, hunters in remote Canadian forests, or ranchers in areas with no cell coverage have used Globalstar phones because they cover those areas and are affordable. It’s also used in industries like forestry, agriculture, or logistics in rural parts of the US/Canada – where workers can carry a Globalstar phone to check in daily. Because of the low incremental cost, some outfitters or guiding companies equip their guides with Globalstar for routine comms (saving the Iridium for when they go out-of-coverage). Another scenario: coastal sailing or fishing – if you sail within say 200–300 miles of shore in the Atlantic, Globalstar might serve you well with clear calls (but you wouldn’t rely on it for a transoceanic crossing). The local number feature also made Globalstar a choice for some emergency agencies; for instance, a county emergency management might have a few Globalstar phones so that if cell networks go down, they have a backup that can integrate with their phone system cheaply (as long as the crisis is within coverage). In short, Globalstar is the go-to for budget-minded users who operate in covered zones. It’s not for the extreme explorer who might be literally anywhere on the globe. But for those who know their region is supported, it can be a very smart choice.
Latest News & Future Outlook (2025 and beyond)
The satellite phone industry is at an interesting crossroads in 2025. On one hand, devices like the Iridium 9555, IsatPhone 2, Thuraya XT-PRO, and GSP-1700 represent mature, well-tested technology that has remained relatively unchanged for a decade. (Indeed, the 9555 and GSP-1700 are well over 15 years old in design, and even IsatPhone 2 is 11 years old.) They are reliable and have saved countless lives. On the other hand, we’re seeing a surge of new satellite technologies that promise to change how we communicate off-grid – notably, the incorporation of satellite messaging into ordinary smartphones.
In recent news, Iridium Communications completed the deployment of its next-gen satellite constellation (Iridium NEXT) by 2019, which was a $3 billion project to replace all its satellites. This has kept Iridium’s network modern, with improved voice call stability and paving the way for new services (like their higher-speed Certus data service for specialty devices). Iridium also made headlines by partnering with Qualcomm in early 2023 to enable two-way satellite texting on Android smartphones via Snapdragon Satellite theregister.com theregister.com. This would have allowed premium Android phones to send messages over Iridium satellites when out of cell range. However, by late 2024, Qualcomm surprisingly terminated that agreement, citing that phone makers prefer open standards for satcom theregister.com. Iridium’s CEO, Matt Desch, remained optimistic, noting that multiple manufacturers and carriers are still interested in integrating satellite connectivity and that Iridium’s global network positions it well as this develops theregister.com. In effect, Iridium may still end up on smartphones via a different route (perhaps through 3GPP NTN standards). This shows that while Iridium 9555 the device might not change, the Iridium network’s usage might extend to consumer devices in the near future – something to watch.
Meanwhile, Globalstar scored a huge win by partnering with Apple: since the iPhone 14 (2022), Apple devices can connect to Globalstar satellites to send Emergency SOS texts when off-grid. This service is limited (emergency use only, text only, specific presets) but it introduced millions to the idea of a “satellite phone” feature in their pocket. As of 2025, Apple expanded it to allow limited two-way texting for non-emergency use on iPhones gearjunkie.com gearjunkie.com. This is directly using Globalstar’s network, but you wouldn’t know it as a user – it’s all behind the scenes in iOS. The key point: many people are now wondering, if my smartphone can do satellite texting, do I need a dedicated sat phone? The answer often is yes for voice calls and robust use, but maybe not for basic messaging. It’s an evolving dynamic. Globalstar’s satellites have capacity largely dedicated to Apple now, and they’re launching more gateways and satellites with Apple’s funding. However, Apple’s service has the same limitations as Globalstar’s network (no high-latitude coverage, etc.) gearjunkie.com gearjunkie.com. There is also speculation Apple might allow limited voice via satellite in the future, but nothing concrete yet.
Inmarsat, on its part, merged with U.S. operator Viasat in 2022. Inmarsat is not resting – they launched the I-6 F1 satellite in late 2021 and I-6 F2 in 2023, which augment their L-band coverage, and are planning Inmarsat-8 satellites by mid-decade gearjunkie.com. These will likely ensure Inmarsat’s handheld services (like IsatPhone) remain supported well into the 2030s and might bring incremental improvements (maybe slightly better voice capacity or new narrowband services). They also provide new Ka-band payloads for broadband, but that’s separate from handheld voice. A noteworthy tidbit: Inmarsat is also involved in direct-to-device initiatives via a partnership with MediaTek and others, aiming to allow smartphones to use Inmarsat satellites for texting, similar to what Globalstar/Apple have done. So competition in that niche is heating up.
Thuraya (owned by Yahsat from UAE) is executing a refresh too. The Thuraya-4 NGS satellite launched in January 2025 will replace an older bird and expand capabilities (they mention higher data speeds and broader coverage in its regions) thuraya.com thuraya.com. They also have a Thuraya-5 on the roadmap. Thuraya’s focus seems to be on launching 15 new products across various sectors, possibly new terminals or IoT devices thuraya.com thuraya.com. We might see a next-gen Thuraya phone or hotspot device in the coming years that leverages the new satellite’s power. Thuraya’s SatSleeve (which turns your smartphone into a sat phone for calls/SMS via a cradle) was an early step in convergence; it wouldn’t be surprising if they develop a next-gen SatSleeve or a modular approach for smartphones to connect to Thuraya-4.
On the horizon, we have initiatives like SpaceX’s Starlink “Direct to Cell”. SpaceX has announced that its second-gen Starlink satellites can communicate directly with normal phones (they have big antennas for that purpose). In a partnership with T-Mobile, they plan to start a beta of satellite SMS service in 2024, with aims for voice and data later in 2025 gearjunkie.com gearjunkie.com. If Starlink’s plan succeeds, by using standard 5G protocols, any regular phone on participating carriers could eventually make calls or send texts via satellite when out of cell range. That is potentially a game-changer for casual users – you might not need to buy a sat phone at all for basic safety needs a few years from now. However, such services will likely start with limited bandwidth (so maybe texts first, voice later) and will still have constraints (Starlink’s low orbit satellites are not yet as ubiquitous as Iridium’s for truly global coverage, and they need ground stations or laser links to backhaul).
There’s also companies like AST SpaceMobile and Lynk testing direct satellite-cell connections. In 2023, AST SpaceMobile made news by completing the first satellite phone call using an ordinary smartphone (no special chip) to a satellite and down to a ground network theregister.com theregister.com. These technologies are essentially turning satellites into cell towers in the sky. The implication for sat phones: if mainstream phones can do this, the need for dedicated sat handsets could diminish, at least for non-professional use. However, as GearJunkie’s 2025 review concluded, there is still a place for dedicated satellite phones: “when it’s a zero-sum game, bringing a dedicated device… can make a lot of sense” gearjunkie.com gearjunkie.com. The durability, high-gain antennas, and guaranteed access of a real sat phone are critical for extreme scenarios and heavy users.
Upcoming models? As of 2025, there’s no official announcement of an “Iridium 9560” or something – the 9555 and 9575 Extreme remain Iridium’s duo. It’s possible Iridium will develop a new phone to replace the aging 9555 in the coming years, perhaps adding features like those on the Extreme while reducing cost. But Iridium might also pivot to devices like the Iridium GO! exec (a new portable Wi-Fi hotspot launched in 2023 that lets smartphones make calls over Iridium) – essentially shifting the model from “sat phone” to “satellite access point.” The Iridium GO! (original and new “Exec”) are notable: the GO is a little box that pairs with your smartphone to allow calling and texting via an app ts2.tech ts2.tech. The new GO! exec is larger but offers ~22 kbps internet, catering to those wanting data on the go. These show Iridium’s strategy to integrate with consumer electronics rather than just standalone phones.
For consumers planning ahead: If you need a sat phone now, the current models we discussed are battle-proven and will serve you for years. All networks have plans to maintain or upgrade their constellations, so none of these devices are in danger of becoming obsolete overnight. The Iridium network will be operational well beyond 2030; Inmarsat’s new sats ensure L-band coverage into the 2040s gearjunkie.com; Globalstar is flush with investment due to Apple’s deal, ensuring their network’s viability; Thuraya is renewing its fleet. So buying a sat phone in 2025 is still a sound investment for remote communication needs. Keep an eye on the emerging tech for sure – maybe in a few years your iPhone 17 or Android 15 will double as a mini sat phone for basic tasks. But when you absolutely need to make a call from the ends of the Earth, devices like the Iridium 9555 and its peers are the reliable tools that professionals and explorers will continue to carry.
Choosing the Right Satellite Phone – Use Cases
Adventure Travel & Expedition: If you’re a globe-trotting adventurer visiting truly remote corners (including polar regions), the Iridium 9555 (or Extreme) is your best bet for a satellite phone that works literally anywhere. It’s the safety net when you’re climbing Denali or trekking Greenland – you know you can reach rescue or family from any latitude ts2.tech ts2.tech. Expeditions often also value the Iridium Extreme’s SOS feature, but many still carry the simpler 9555 for voice reliability and maybe a separate PLB (personal locator beacon) for SOS. If your adventures are remote but not at the poles (for example, traversing the Gobi Desert, Amazon rainforest, or sailing from Fiji to Hawaii), an Inmarsat IsatPhone 2 will cover you well ts2.tech ts2.tech. Its superb standby battery is great for multi-week basecamps or sailing voyages where charging may be limited. The slight delay is a small trade-off for solid voice quality in open areas. Now, if your expeditions are region-specific – e.g. overlanding across Africa or exploring the Australian Outback – a Thuraya phone could be a convenient choice due to lower costs and sufficient coverage in those Eastern Hemisphere areas ts2.tech ts2.tech. Just remember to rent or borrow a different phone if you ever take a detour to South America because Thuraya won’t work there.
Maritime & Ocean Use: For blue-water sailors, maritime researchers, or fishing fleets, communication is lifeline. If you’re doing ocean crossings or high-latitude sailing, Iridium is essentially the only game in town for handhelds. It’s common for sailboats in round-the-world races or polar cruises to have an Iridium phone (or an Iridium-based terminal) because they can get emergency weather updates and call from anywhere at sea ts2.tech ts2.tech. Inmarsat IsatPhone 2 is also very popular at sea, especially for lower-latitude routes. Many cruising yachties use IsatPhone 2 for its reliability in the tropics and the long battery (it can stay on to receive calls even during a week-long passage). External antennas are often used on boats – Iridium and Inmarsat both have docking kits that let you mount an antenna outside and use the phone indoors like a cabin phone. Thuraya, due to no Atlantic/Pacific satellite coverage, is mostly useful in regional seas (like Mediterranean, Persian Gulf, etc.). For example, a Mediterranean charter yacht company might equip boats with a Thuraya XT-LITE for cheap emergency calling. Globalstar is not ideal for open ocean (no mid-ocean coverage), but near coastlines it can be fine – e.g. if you’re island hopping in the Caribbean or fishing the Gulf of Mexico, Globalstar would still have coverage and give great call quality for check-ins. The key for maritime: decide if you’ll be in the broad ocean or near land/coastal – that will determine if you need Iridium/Inmarsat (global) or could use Globalstar/Thuraya (regional coastal).
Emergency Preparedness & Disaster Response: When infrastructure fails (hurricanes, earthquakes, power blackouts), sat phones become critical. Government agencies and NGOs often maintain a cache of Iridium phones because they know no matter where they deploy (even foreign countries), Iridium will work with minimal setup ts2.tech ts2.tech. For example, after a Caribbean hurricane, responders used Iridium handsets because local cell networks were down and Inmarsat was already saturated – Iridium’s multiple satellites allowed more concurrent calls in some cases. That said, Inmarsat IsatPhone 2 is also a staple for disaster teams – its simpler logistics (no moving satellites) can mean slightly easier use for volunteers, and the incoming call standby battery life means a coordination center can reach field teams anytime. If you’re an individual prepping an emergency kit for, say, your remote home or for a regional disaster, and you live in a not-too-northern area (say ≤ 60° latitude), an IsatPhone 2 gives a lot of standby readiness. But if you’re in Alaska or wanting the absolute assurance of connectivity under any sky, Iridium’s the pick. Globalstar phones play a role for local emergency prep too – e.g. some wildfire-prone communities in California acquired Globalstar phones for key personnel, since those work well in California and are cheaper to use, enabling more frequent testing and use (and indeed, unlimited talk plans mean they can be used like regular phones in an extended outage without huge bills ts2.tech ts2.tech). For a personal/family emergency kit in, say, the midwestern US or Europe, a second-hand Globalstar could be an economical way to have satellite capability to call for help if cell lines are down – as long as you know its coverage limits. In summary, for critical mission-ready comms, Iridium and Inmarsat are the global gold standards, while Thuraya and Globalstar can fill specific regional needs effectively and affordably.
Remote Work (Mining, Oil & Gas, Research Stations): These sectors often have semi-permanent operations in remote areas. Oil & Gas fields in the Middle East, North Africa, or Central Asia commonly use Thuraya or Inmarsat phones for field engineers – Thuraya because it’s local and cheap, Inmarsat for near-global rig coverage. Mining sites in Canada or exploration teams in Siberia might lean on Iridium or Globalstar depending on latitude (Iridium for high north). Scientific research stations – e.g. a rainforest ecology camp in Congo – might use Inmarsat for reliable comms to headquarters, whereas a research vessel in the Arctic will definitely use Iridium. One interesting use case is remote aviation: bush pilots in Canada or Alaska often carry Iridium phones (some even dock them into aircraft comm systems) to file flight plans or call for weather updates. Globalstar had a niche here when their service was strong in the 2000s due to clear voice, but Iridium’s reach has won out for true bush flying where you may go in and out of coverage.
Casual Backpackers & Hikers: Many outdoor enthusiasts nowadays consider a satellite messenger (like Garmin inReach) for routine hiking, which allows texting and SOS. These devices use the Iridium network for global text coverage. For someone who mostly wants to send an “I’m OK” message or have an SOS safety net on weekend hikes, an inReach or similar might be sufficient (and cheaper to buy and run) gearjunkie.com gearjunkie.com. However, a two-way messenger cannot make a voice call. If you value hearing a human voice and the ability to have a real-time conversation (which can be very comforting or crucial in a crisis), a sat phone is still the superior tool. So a casual backpacker in the Rockies, if budget allows, could carry a Globalstar GSP-1700 or an older used Iridium for that “just in case” voice call to SAR or family. But many opt for the lighter text-only devices. It’s about what level of communication you foresee needing. The GearJunkie review highlighted that if all you need is tracking or quick check-ins, a satellite messenger might be your best bet, whereas a phone is for when you need a real conversation or more direct connectivity gearjunkie.com gearjunkie.com.
Journalists & Media in Conflict Zones: Sat phones often appear in news images from war zones or remote conflict areas – e.g. journalists reporting from areas with destroyed networks or where internet can be cut off. In such cases, Iridium and Thuraya have both been used. Thuraya has been popular in Middle East conflicts (like in Syria or Iraq) because it’s regionally available; but there’s a risk – some governments track or jam Thuraya phones (and in some countries sat phones are illegal) gearjunkie.com gearjunkie.com. Iridium, being U.S.-operated, is sometimes restricted in sanctioned countries (e.g. you might not get service in North Korea or Cuba due to U.S. embargo rules) gearjunkie.com. In fact, the Iridium 9555’s cons list includes that global coverage doesn’t include U.S. embargoed countries gearjunkie.com. Journalists thus have to be mindful of legalities. The IsatPhone 2 could be a neutral choice in some areas, given Inmarsat’s global service not tied to U.S. sanctions (though local laws still apply – India famously bans private sat phones). For media use, the ability to send not just voice but data (copy, photos) matters; here a BGAN terminal (Inmarsat’s broadband) is often used instead of a handheld. But for pure voice and coordination, any of these phones could be used depending on region. The main consideration is anonymity and legal status – which is beyond the scope here but crucial for those users.
Recreational Remote Travel: Think overlanding expeditions, long road trips through sparsely populated areas, safaris, etc. If you’re driving across Africa or Asia, Thuraya’s a logical choice because the network is tailored for those regions and costs are lower. If doing the Pan-American highway through South and Central America, Inmarsat or Iridium would be needed since Thuraya won’t work; many choose Inmarsat for that kind of trip because you get broad coverage except maybe near the very high latitudes, and the phone is a bit cheaper. If camping in the Australian Outback – Thuraya again covers that. If off-roading in Mongolia – Thuraya (on the fringe, but it covers a lot of Central Asia) or Iridium for full certainty. Globalstar could be fine for drives across the US or Canada – for example, RV enthusiasts who go off-grid in national parks sometimes keep a Globalstar phone for emergency since it’s affordable and works in most of North America’s visited areas.
In sum, matching a satellite phone to your use case involves balancing geographic coverage needs, budget, and required features. The Iridium 9555 remains the “go anywhere” solution, Inmarsat IsatPhone 2 covers almost all needs with the best stamina, Thuraya serves regional adventurers with cost-effective options, and Globalstar offers a low-cost lifeline for those who roam within its zone. Many seasoned travelers actually carry two systems for redundancy (e.g. an Iridium plus a Globalstar or Thuraya) – but for most, one well-chosen sat phone is sufficient insurance to stay connected when it truly matters.
