---Advertisement---

While most of us are very familiar with smartphones, satellite phones and messengers are still rather niche. But if, like me, you find yourself outside the comforting embrace of Wi-Fi and cellular coverage, having a device that allows you to remain in contact with civilization isn’t just handy, it can be a lifesaver.

I’ve been tested a whole range of devices, from satellite messengers akin to two-way pagers such as the $200 SpotX, to the Starlink Mini, a $500 portable satellite dish that can give me high speed internet access anywhere on the globe. Read on to see which devices are the best.

What is the best satellite phone right now?

If you’re keen on staying connected no matter where you roam, ZDNET has done extensive research and hands-on testing with some of the best satellite phones and gadgets on the market. My top pick right now is the Starlink Mini, simply because it’s one of the cheapest ways to access the full internet, and everything that offers, when on the go.

Check out my complete list to see how other favorite models from Spot, Garmin, and more compare in terms of features. You’ll find the perfect satellite phone or communicator to suit your habits and budget.

The best satellite phones and communicators of 2025

Why we like it: I’ve tested and used a number of satellite phones and communicators. When it comes to their offerings, the features are incredibly limited, while monthly contracts costs are sky-high. Yes, they’re highly portable, but you’re limited to tracking, SOS and simple messaging.

Enter the Starlink Mini. While the dish will set you back a fair chunk of change, and it’s not something you’re going to fit in your pocket, with it you then get access to high-speed internet across most of the globe.

There’s a lot to like about the Starlink Mini package. You get true internet access, high-speed data transfer, and the ability to use it on the move in a vehicle. The dish is also small, lightweight, and can even be run from a power bank.

Who it’s for: This dish is for those who want high-speed access to the internet from anywhere. Maybe you’re a photographer or videographer who needs to send content to an editor or back up files, or maybe you’re setting up a camp for a group of people who don’t want to be without their social media.

Who should look elsewhere: If you’re looking for something small, lugging a satellite dish — even a rather small one — isn’t going to be for you. You’re best off looking for something more portable.

Why we like it: This is the cheapest satellite messenger that I recommend coming in under $100. The Spot Gen 4 can send an SOS, pre-customized messages, and position updates with the press of a button.

Don’t let the price fool you. This satellite messenger is rated IP68 and MIL-STD 810F, so it’s as tough as they get. It can also send up to 1,250 check-in and custom messages on a single set of four AAA lithium batteries.

A great option for those who want a low-cost, no-frills messenger.

Who it’s for: If you’re needs don’t go much further than messaging and summoning help if things go bad, this is perfect. It’s a cheap option that hikers, backpackers, and even outdoor workers can carry with them to keep in touch and as insurance against things going bad.

Who should look elsewhere: If you need access to the full internet, this is not for you. If you want a device that can operate separate to your smartphone, this also isn’t for you

Why we like it: This mobile satellite router connects to the Iridium satellite constellation. You get enough data bandwidth to check emails, use Twitter, pull up weather forecasts, and limited web browsing. You can connect up to five devices to the Iridium Go! hotspot. What I like about this setup: You unbox it, power it up, let it see the sky, and then it acts like a Wi-Fi router you might have at home.

This is not a cheap kit, and it’s designed for those who truly want to go off-grid. It includes the Iridium Go! base station, an AC travel charger with an international adapter, as well as a solar charger and a desktop charger. Additionally, the unit offers up to 15.5 hours of standby battery life and up to 5.5 hours of talk time. Its various features make it ideal if you’re looking to stay connected while exploring remote areas. Its compact design measures 114mm x 82mm x 32mm and weighs only 305g, making it easy to carry around.

The router offers both satellite calls and satellite SMS, allowing you to communicate with others even in areas without cellular coverage.

Review: Iridium GO! Turn any smartphone into a satellite phone

Who it’s for: This is for those people who need satellite internet access to a number of different devices, but don’t want to carry a Starlink Mini dish about with them. This does have more limitations than Starlink, but the trade-off is greater portability and a self-contained unit that doesn’t need external power.

Who should look elsewhere: If the $899 price tag gives you cause to sit down, this isn’t for you. If you think the hardware is expensive, you’re not ready for the pricey service plans costing between $70 and $180 a month.

Why we like it: With satellite communication now built into the Apple iPhone and Google Pixel, the companies that make messengers need to up their game. Garmin unveiled the inReach Messenger Plus which is one of the first satellite communicators to provide photo and voice messaging capabilities in addition to text messaging, location sharing, and SOS communications.

With the inReach Messenger Plus, you can enhance your outdoor adventures by sending 30-second voice messages, text messages up to 1,600 characters — including emojis. You can also share your route and GPS location, allowing family and friends to track your journey. Additionally, it accesses weather forecasts to stay informed while exploring the great outdoors, making this device an essential companion for adventurers.

As a standalone satellite communicator, the inReach Messenger Plus ensures you’re never out of touch. Even if your smartphone battery dies or gets damaged you can still notify contacts of your status, share your location, and send SOS messages.

The inReach Messenger Plus is rugged and has an IPX7 water-resistant rating, which means it’s built to withstand the elements and survive accidents better than most devices.

Who it’s for: If you want a way to stay in touch when out and about off-grid with photos and voice clips, this is a great option. It also offers the usual route tracking, messaging, and SOS features.

Who should look elsewhere: Those looking for full internet access need to look at something like the Starlink Mini or the Iridium Go! Also, if photo and voice isn’t important, there are cheaper options.

Garmin inReach Messenger Plus tech specs: Dimensions: 78mm x 64mm x 23mm | Weight: 117.2g | Services: Satellite messaging, location tracking, SOS, and photo/voice message service | Battery life: Up to 25 days of battery life in 10-minute tracking mode | IP Rating: IP7X | Price: $500

Why we like it: Spot is another company that offers satellite trackers and messengers. There’s the , a two-way device that looks a lot like an old Blackberry; the , which lets you send check-in and SOS messages; and the , which allows tracking things like cars and suitcases.

Spot X features a physical keyboard that is easy to use, especially if you prefer tactile buttons to touchscreens. The device is durable, too, meeting MIL-STD-810G standards for shock resistance and boasting an ingress protection rating of IP67. At 166mm x 38mm x 24mm and weighing 198g, the device is fairly portable and can last up to 240 hours. I hang mine from the chest strap of my backpack, so it has the best view of the sky.

One of the Spot X’s most impressive features is its SOS button, which you can use in an emergency situation. This is a particularly useful feature if you engage in outdoor activities and can find yourself without cellular coverage. I’m planning 10-day hike in northern Spain later this year, and it’s this is the messenger I’ve chosen to take with me.

Also: I held the world’s thinnest foldable phone, and it made my Samsung Galaxy Z Fold 6 look outdated

Who it’s for: Whereas most messenger units rely on a smartphone connection or a poor on-screen keyboard for test entry, this one is the perfect satellite messenger for those who want a self-contained unit with a decent physical keyboard.

Who should look elsewhere: There are smaller satellite messengers out there, so if you’re a thru-hiker or you’re someone where weight is an issue, this might not be the best choice for you.

Why we like it: One of the standout features of the Garmin Mini 2 is the battery life. It offers up to 14 days in 10-minute tracking mode which is perfect for those extended treks when you’re not going to be able to recharge things.

It also has a monochrome display that’s easy to read in all lighting conditions, and it’s waterproof with an IPX7 rating. It has USB-C for easy charging and connectivity with other devices.

It’s a great self-contained unit for those who want to keep in touch when off-grid.

Review: Garmin inReach Mini 2 review

Who it’s for: The Garmin Mini 2 is a popular choice for anyone wanting an affordable, easy to use, yet reliable and robust satellite messenger. I’ve seen these in the hands of hikers, bikers, canoeists, outdoor workers, and more. It’s a great choice for when the smartphone isn’t enough.

Why we like it: The Inmarsat IsatPhone 2.1 is a fully featured satellite phone with near-global coverage and good battery life.

The Inmarsat IsatPhone 2.1 offers the ability to make and receive voice calls, send and get SMS, and track your position with GPS from anywhere on the globe.

It has an IK04 shock resistance rating, and the entire package is IP65 rated for dust- and waterproofing. The built-in lithium-ion battery offers eight hours of talk time and 160 hours on standby.

Who it’s for: It’s good to talk, and this is who this is aimed at — someone who just needs a phone that will work where cellphone coverage is non-existent.

Who should look elsewhere: If you’re someone who rarely uses the phone part of their smartphone, this is not for you. Also, the cost of the hardware and the plans are quite eye watering, so this isn’t something for the casual user.

What are the tariffs in the U.S.?

The recent U.S. tariffs on imports from countries like China, Vietnam, and India aim to boost domestic manufacturing but are likely to drive up prices on consumer electronics. Products like smartphones, laptops, and TVs may become more expensive as companies rethink global supply chains and weigh the cost of shifting production.

Also: Tariff war has tech buyers wondering what’s next. Here’s what we know

Smartphones and satellite phone and satellite messengers are among the most affected by the new U.S. tariffs, with devices imported from China and Vietnam facing steep duties that could raise retail prices by 20% or more. Brands like Apple and Google, which rely heavily on Asian manufacturing, may either pass these costs on to consumers or absorb them at the expense of profit margins.

The tariffs could also lead to delays in product launches or shifts in where and how phones are made, forcing companies to diversify production to countries with more favorable trade conditions.

Right now, it looks like some tech may be exempt from the issued tariffs, but since it’s always changing and developing, we are keeping an eye on it and will update you on the latest.

Also: Tariff exemptions for electronics offer a break for tech – but not for long

When determining which satellite phone is best for you, three factors come into play:

What do you need the satellite phone for? Expeditions? Hiking? Emergency use?
How much are you willing to spend? Prices start at just over $100 and quickly jump into the thousand-dollar range.
The network. Not all satellite networks have global coverage.

For example, if you want an affordable communicator that has global coverage capabilities, the Garmin inReach Mini 2 fits the bill. Want a budget communicator option? The Motorola Defy fits the bill. Meanwhile, if you want a satellite phone that can switch from GSM to satellite easily, the Thuraya XT-LTE is a wise choice.

Note: Prices and availability may vary.

Selecting the right satellite phone depends on your requirements and priorities. It’s essential to prioritize why you need the phone and your own budget. This will help you to select the best phone at the best price, and more importantly, you’ll have a communication tool that works where you are when you need it the most.

Below are the key considerations and how each phone aligns with specific purposes:

Choose this best satellite phone…	If you want…
Starlink Mini	Access to the internet as a whole. Forget about just being able to send messages or access the weather, with a Starlink Mini and a view of the sky, you can get high-speed internet from over 100 countries.
Spot Gen 4	The lowest-cost way to get access to satellite messaging. This handles SOS messaging, check-ins, location data, and pre-configured messages.
Iridium Go!	Global coverage and the ability to create a hotspot for multiple devices. The Iridium Go! is the best choice because it offers satellite calls and SMS, has good battery life, and is MIL-STD 810F certified for durability.
Garmin inReach Messenger Plus	A small, tough messenger that can handle text, voice notes, and photos, and also be an emergency SOS device. this can be used with your smartphone or standalone in an emergency.
Spot X	Something for occasional use or emergency situations. The Spot X is a good choice because it has an SOS feature and is low-cost, but it has limited features and a small physical keyboard.
Garmin inReach Mini 2	Occasional satellite communication and SOS support. The Garmin inReach Mini 2 is ideal because it is affordable, lightweight, and offers a range of features such as two-way messaging, interactive SOS, and TracBack routing.
Inmarsat IsatPhone 2.1	A classic satellite phone with global coverage. The Inmarsat IsatPhone 2.1 offers voice calls, SMS, GPS tracking, and a programmable emergency assistance button. It is, however, big, bulky, and expensive.

Cost: Satellite communication tends to be more expensive than cellular services. The cost of the phone itself, along with the service plans and price per minute for calls, can be significantly higher.
Size and Weight: Satellite phones are generally bulkier and heavier than modern smartphones, which might be a concern if you need to minimize their load.
Data Speeds: While some satellite phones offer data services, the speeds are usually much slower than what you’re accustomed to with 4G or 5G cellular networks. This may affect the usability of internet-dependent applications.
Satellite Visibility: Different satellite systems, such as Iridium, Globalstar, and Inmarsat, offer different types of coverage of the globe, so bear this in mind when you’re choosing a system for your adventures.

When selecting the best satellite phone, I tested some of the devices and took into consideration other devices and various factors, such as price, availability, coverage, and use case. I carefully analyzed each device and weighed the pros and cons before arriving at my conclusions.

Price: The price tag is always a factor, especially for those who are going to use their satellite phone only occasionally.
Coverage: Not all satellite networks offer global coverage, so knowing this in advance is important.
Use case: Are you looking for a traditional satellite phone, or do you want something more specialized, like a satellite hotspot or emergency beacon?
Reviews: What are others saying about these devices? I looked at reviews on Amazon, Reddit, and a bunch of other outlets to get a consensus of the hardware and the satellite service.
Hands-on experience: Over the years, I’ve used a number of these devices, sometimes briefly, sometimes for several weeks or months. This allows me to get a better understanding of the device.

Latest info on satellite phones and messengers in 2025

At the end of July, Starlink suffered a rare issue that knocked tens of thousands of users offline for over two hours. While social media was awash with talk about hacking and solar flares, the real issue behind the downtime was rather prosaic — software failure.

A satellite phone is a mobile device that uses satellites to communicate instead of cell towers. The primary function of a satellite phone is to make and receive calls and SMS messages from virtually anywhere in the world, including remote areas without cell coverage.

These are devices that, like satellite phones, connect to an orbiting constellation of satellites orbiting thousands of miles above the Earth, typically in low Earth orbit (LEO) or geostationary orbit (GEO). These satellites relay signals between the phone and ground-based stations, which then connect the call to the regular phone or data network.

Some are standalone devices that have built-in keyboards, while others rely on a connection to a smartphone for the keyboard and display.

Satellite phones and satellite communicators can range in price from a few hundred to several thousand dollars, depending on the features and capabilities of the device. Service plans also vary in cost depending on the provider and coverage area.

No. Satellite communication units require a clear view of as much of the sky as possible, as they communicate directly with satellites orbiting the Earth.

You can use external antennas and repeaters if you require a more permanent solution for indoor use.

Sort of.

Apple has added a feature called “Emergency SOS via satellite,” which allows you to contact emergency services when you’re in an area without cellular or Wi-Fi coverage.

Apple said that “Emergency SOS via satellite” would be free until about November 2024. After that, Apple plans to start charging for the service, although right now we don’t know the price.

This service is currently available in the U.S., Canada, and most of Western Europe.

Also: iPhone 15 Plus review

Not really. They’re big, bulky, expensive, and the data rates are awful compared to even 3G. Instead, they offer services that regular smartphones cannot match.

If you’re an avid hiker or camper, you know that remote areas don’t have the best cellular service. This is where satellite phones come in handy: they give you access to communication in areas where cellular companies don’t.

It’s less about which is the best and more about what bits of the planet you want coverage on. Every network offers maps and details of coverage. Keep in mind that not all networks offer global coverage.

Check coverage at the time of purchase because it can, and does, change regularly. Doing so ensures you have the right phone and network for where you need it.

Depending on the satellite network, sat phones can provide near-global coverage, even in the most isolated locations. Popular satellite networks include:

Iridium — provides global coverage using a constellation of LEO satellites.
Starlink — provides global coverage using a constellation of LEO satellites.
Inmarsat — uses GEO satellites for wide coverage, excluding polar regions.
Globalstar and Thuraya — regional coverage with partial global access.

Not all do. In fact, coverage varies considerably between the networks.

Starlink

Starlink coverage is available in over 100 countries. Coverage map can be found on the company’s website.

Iridium

Iridium offers global coverage. Live map of satellite locations is available on Iridiumwhere.com.

Globalstar

Globalstar coverage maps can be found on the company’s website.

Inmarsat

Inmarsat has nearly global coverage. Maps can be found on the company’s website.

Satellite phones, like the Thuraya XT-LITE, offer features that you typically find on cellular phones, such as calling and messaging. While the Thuraya XT-LITE does not offer global coverage and both North and South America are not covered, it has a unique ability to toggle between a GSM network and satellite communications. This means that you don’t have to worry about dropped calls in remote locations.

Plus, the phone only requires one SIM card. Additionally, it has a rugged body, making it a durable option for outdoor adventures. Keep in mind that satellite phones still have drawbacks compared to smartphones, such as bulkiness and limited data rates.

Based on my personal experience, satellite phones are highly reliable and serve as a great insurance policy if you’re heading out into remote and uncharted territories. Since they operate on satellite communication, they offer a wide range of coverage that is not available with cellular service, especially in mountainous regions or areas with limited network coverage.

Satellite devices do have some limitations, such as slower communication speeds than smartphones. It’s important to keep this in mind when planning for emergency situations or other time-sensitive communication needs.
