Satellite phones are an absolute game-changer for those venturing into remote areas that lay beyond the reach of traditional mobile networks. Unlike standard smartphones that rely on cellular networks made up of physical towers, satellite phones communicate directly with satellites orbiting about 500 miles above Earth, ensuring you stay connected even in the most isolated locations.

Maintaining contact in an area with inadequate cellular coverage is challenging, so a satellite phone can be invaluable. I've used a variety of satellite phones and communicators during off-grid adventures. Sometimes I use them to stay in touch with others, and other times they're a precaution in case of emergencies, allowing me to hit the SOS button and summon help -- a feature I thankfully haven't needed yet.

The best satellite phones and communicators of 2024

Iridium Go!

Best satellite phone and gadget overall

This mobile satellite router connects to the Iridium satellite constellation, and 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 much like a Wi-Fi router that you might have at your office.

This is not a cheap kit, and it's designed for those who truly want to go off-grid. It includes not only the Iridium Go! base station and AC travel charger with an international adapter but also comes with 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 for those looking to stay connected while exploring remote areas. Its compact design measures 114 by 82 by 32 mm and weighs only 305g, making it easy to carry around.

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

When it comes to communication, the router offers both satellite calls and satellite SMS, allowing users to communicate with others even in areas without cellular coverage.

The Iridium Go! operates within a temperature range of 10 to 50 ℃ and meets MIL-STD 810F standards, meaning it can withstand harsh environments and extreme weather conditions. With an IP65 rating, it's also dust-tight and can withstand water jets from any direction.

Reviews and comments are divided -- those who have bought one are over the moon with its capabilities, ease of use, and the power it offers. Other reviewers have lamented the price, but it's worth noting it doesn't cost any more than a premium smartphone.

Spot X

Best stand-alone satellite communicator

Another company that offers satellite trackers and messengers is Spot. There's the , a two-way device that looks a lot like an old Blackberry, the , which allows the user to send check-in and SOS messages, and the , which allows tracking of things like cars and suitcases.

Spot X features a physical keyboard that is easy to use, making it a popular choice for those who prefer tactile buttons over touchscreens. The device is durable, too, meeting MIL-STD-810G standards for shock resistance and boasting an ingress protection rating of IP67. At 166 by 38 by 24 mm and weighing 198g, the device is fairly portable and can last up to 240 hours.

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

However, one of the most impressive features of the Spot X is its SOS button, which can be used to help in an emergency situation. This is a particularly useful feature for those who engage in outdoor activities and may find themselves in areas without cellular coverage.

Reviewers on Amazon and Reddit all say that while the device's interface can be a bit slow -- think cellphone-from-a-decade-ago slow -- the backlit Blackberry-style keyboard and screen are game-changers because it means you don't need to rely on a separate smartphone to be able to text rapidly. Yes, it's bigger than communicators that rely on an on-screen keyboard or your smartphone to act as a keyboard, but it's a self-contained bit of kit.

Garmin actually makes many satellite-enabled devices, from the simple to the .

Read the review: Garmin inReach Mini 2 review

The Mini 2 has a battery life of up to 14 days in 10-minute tracking mode, a monochrome display that's easy to read in all lighting conditions, and is waterproof with an IPX7 rating. It features a USB-C interface for easy charging and connectivity with other devices.

While the Garmin inReach Mini 2 is a versatile and feature-packed device, it does have a few potential downsides to consider. Firstly, it requires an active satellite subscription, which can add to the overall cost of the device. And the device's messaging capabilities are limited to text-based communication.

User reviews show a high level of satisfaction for this satellite communicator, and having used one, I understand. It's a fantastic bit of kit that offers peace of mind.

Inmarsat IsatPhone 2.1

Best satellite phone and gadget for voice calling capabilities

Now we move on to something that looks and acts like a phone. 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, SMS, track your position with GPS from anywhere on the globe. (Well, mostly, satellite coverage at the north and south poles is poor. Outside of those areas, people will get excellent coverage.)

It has an IK04 shock resistance rating, can withstand dirt, dust, and water, and provides enhanced daytime visibility. The built-in lithium-ion battery offers 8 hours of talk time and 160 hours standby, and the entire package is IP65 rated for dust- and water-proofing.

Online reviews echo that it's big and bulky, but it's a reliable satellite handset for those looking for voice, SMS, and tracking. It's tough and built for the outdoors, and despite dropping one on the ground several times, and following that up by dropping it into a lake, I couldn't break the one I tested.

Motorola Defy Satellite Link

Best budget satellite gadget

The new Motorola Defy Satellite Link functions as a satellite hub to pass messages, or an SOS signal, to others from your connected smartphone, whether that be an iPhone or Android. And it's not a huge thing to carry, measuring 82 x 62 x 11.2mm and weighing only 70 grams.

The Motorola Defy is reasonably priced, starting at $106, with low-cost satellite subscription plans that make it a must-have for anyone who travels in an area with no cellular coverage.

Read the review: Give iPhone or Android satellite messaging powers with this handy device

Given the price of the hardware and the low cost subscription plans, it is worthy of being in your vehicle as an emergency messaging device. It is perfect for hikers and outdoor adventurists who travel on shorter trips or who carry along an external battery pack on longer trips.

The reviews across the board highlight how cheap this satellite communicator is compared to the competition.

Thuraya XT-LITE

Best satellite phone and gadget for dual connections (outside of the US)

Is it a satellite phone? Is it a regular GSM phone? The Thuraya XT-LITE is both, all using a single SIM card. And better still, it automatically switches from satellite to GSM without any hassles... so no forgotten calls because you're out of coverage.

The Thuraya XT-LITE has a battery life of up to six hours of talk time and 80 hours of standby time. The phone comes with a travel charger and USB cable. It is easy to use and can be programmed in various languages. Overall, it is a decent, rugged, no-frills sat phone.

Note that the Thuraya satellite network does not offer coverage in the US, so this is a sat phone for when you're in other territories.

So, which is best suited to you?

Three factors in particular 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 spiral into the thousand dollar mark.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.

When it comes to selecting a satellite phone, there are various options available in the market. However, selecting the right one 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...
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.
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. However, it has limited features and a small physical keyboard.
Motorola Defy	A low cost subscription with satellite coverage across the US. Excellent for an emergency device or one for trips shorter than 4 days. A Bluetooth connection and proprietary messaging app are needed, but the pricing opens up satellite messaging to more people.
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.
Thuraya XT-LTE	A satellite phone that also acts as a smartphone. The Thuraya XT-LTE is the best option because it has both satellite and GSM capabilities and is rugged, making it ideal for outdoor activities. However, it doesn't offer global coverage and has a limited battery life.
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. However, it is 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 for those needing 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, Inmarsat, etc -- offer different coverages of the globe, so bear this in mind when when choosing a system for your adventures.

When selecting the best satellite phone, I personally 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: Cost 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 look at reviews on Amazon, Reddit, and a bunch of other outlets to get a consensus on opinion 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.

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, but rather than being focused on voice calls, their focus is sending and receiving SMS and email messages. 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.

External antennas and repeaters can be used where a more permanent solution is needed for indoor use.

Well, sort of.

Apple has added a feature called Emergency SOS via Satellite which allows owners to contact emergency services when in an area without cellular or Wi-Fi coverage.

Emergency SOS via satellite is free for the next two years. After that Apple plans to start charging for the service, although right now we don't have a price.

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

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

If you're an avid hiker or camper, you know how 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 cellular companies don't.

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

And it's advisable to check this at the time of purchase because coverage can (and does) change regularly. Doing this ensures you have the right phone and network for where you're requiring it.

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

Iridium

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 won'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. However, satellite phones still have some 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 for individuals 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.

However, it's important to note that satellite devices do have some limitations, such as slower communication speeds than smartphones. Therefore, it's important to keep this in mind when planning for emergency situations or other time-sensitive communication needs.

While the market isn't necessarily flooded with options for satellite phones and gadgets, there are other products worth considering. Here are a few I recommend:
