Buying Guide: How to Choose Your Satellite Phone
When I’m looking at gear for my emergency kit, a satellite phone is one of the most critical and expensive pieces. It’s not a purchase you make on a whim. You need to think about the network it uses, its durability, and how it fits into your specific survival plan. Let’s break down what I consider the most important factors when choosing one of the 10 best satellite phones for survivalists and emergency prep in 2025.
First, you have to look at the satellite network. This is the backbone of your device. The two main players are Iridium and Inmarsat (now part of Viasat). Iridium has a constellation of dozens of satellites that crisscross the poles, offering true global coverage, including the poles and open oceans. This is my go-to for truly remote, off-grid adventures. The other major network is Inmarsat, which uses geostationary satellites. These provide fantastic coverage over most of the inhabited world but can have trouble in deep canyons or very high northern latitudes. Globalstar is another option, but its coverage is more regional. Your choice here dictates where your phone will and won’t work.
Next, consider the device type. Do you want a classic handset or a satellite messenger? A dedicated sat phone, like an Iridium 9575 or an IsatPhone 2, is built like a tank and is designed primarily for voice calls. They are robust and reliable. On the other hand, a satellite messenger or hybrid device, like a ZOLEO or some Garmin inReach models, focuses on text-based SOS and messaging, often pairing with your smartphone. These are lighter, more affordable for many, and perfect for sending “I’m okay” check-ins. For pure, reliable voice communication in a worst-case scenario, a dedicated sat phone is hard to beat.
Battery life is a huge deal. In an emergency, you might need this device to last for days on a single charge while waiting for help. Look at the specs for talk time, but pay even more attention to standby time. A phone that offers 30+ hours of standby can be a lifesaver, literally. Also, check if the battery is removable; having a spare, charged battery in your kit is a simple and effective way to double your operational time.
Finally, think about durability and extra features. Your survival phone isn’t living a cushy life. It needs to be rugged, often meeting military standards for shock, dust, and water resistance (look for an IP rating). Beyond the basics, some phones offer GPS tracking, SOS buttons that connect directly to emergency coordination centers, and data capabilities for slow-but-usable email. Weigh these extras against the core function: reliable communication when all else fails. Your choice should be a balance of network reliability, device toughness, and battery life that fits your specific preparedness scenario.
Frequently Asked Questions
How much does it cost to own and use a satellite phone?
This is the big question. The cost has two parts: the device itself and the service plan. You can buy a sat phone for a few hundred to over a thousand dollars. The ongoing cost is the service plan. Many providers have moved away from expensive monthly contracts and now offer flexible, pay-as-you-go plans. You might pay a small monthly fee to keep the number active and then purchase airtime bundles for minutes and texts as you need them. For preppers, this is ideal because you can keep the phone in your kit without a huge recurring bill, only paying for service when a real disaster strikes or you go on a camping trip. Expect to pay a dollar or more per minute for calls and a similar amount for each SMS message.
Will a satellite phone work everywhere, including inside a building or a forest?
No, and this is a critical limitation to understand. Satellite phones need a clear, unobstructed view of the sky to connect to the orbiting satellites. They will not work inside most buildings, in dense urban areas with tall buildings, or under a thick forest canopy. For the best performance, you need to be in an open area. I always make sure I can see a large portion of the sky before I try to make a call. Thick storm clouds usually aren’t a problem, but solid obstructions like a roof or a mountain ridge will block the signal completely.
What’s the difference between a satellite phone and a device like a Garmin inReach?
This is a key distinction. A traditional satellite phone is primarily for two-way voice calls. You use it much like a cell phone, dialing a number to talk to someone. Devices like the Garmin inReach or ZOLEO are satellite communicators. Their main strength is two-way text messaging and sending an SOS to a dedicated emergency response center. They often pair with a smartphone for a better typing experience. While some newer models offer limited voice capabilities, the experience and reliability are not the same as a dedicated sat phone. For quick check-ins and SOS, a messenger is great. For having a full conversation, a sat phone is the tool for the job.
Do I need a special license or permission to use a satellite phone?
In most countries, no, you do not need a special license for personal use. The phone and its service are regulated by the provider. However, it is your responsibility to check the local laws of the country you are in. Some countries, for political or security reasons, strictly prohibit the use of satellite communication devices without a permit. It is illegal to use them in nations like North Korea, and others like China, India, and Russia have heavy restrictions. Always research the telecommunications laws of your destination before you travel to avoid having your device confiscated or facing legal penalties.
How reliable is the SOS feature on these devices?
The SOS feature on reputable satellite phones and messengers is extremely reliable. When you trigger an SOS, the device sends a signal with your GPS coordinates to a professional emergency response coordination center, such as the GEOS International Emergency Response Coordination Center (IERCC). These centers are staffed 24/7 by trained personnel who will assess your situation and coordinate with the appropriate local search and rescue authorities. It is not a direct line to 911, but rather a globally managed emergency service designed specifically for remote incidents. It’s one of the most valuable features for any survivalist or backcountry traveler.
