Using a satellite phone can provide you with communication anywhere globally. Using a satellite allows you to keep in touch with friends and family, whether you’re hiking in remote areas, sailing, flying, or just want to be prepared in case of a natural disaster. While cell phones and smartphones provide connections in major cities and towns, they’re dependent on terrestrial towers. In case of a natural disaster, cellphone networks can be overloaded or subject to structural damage. With one of the best satellite phones, your connection is dependent on satellites in space, so after a disaster or even if you’re traveling to the far corners of the Earth, you’ll be able to stay connected. 

Satellite phones can be used for voice calls, text messaging, and even basic emails to keep in touch. They allow for emergency preparedness by issuing SOS distress signals, GPS locations, directions, and emergency weather alerts. Some sat phone packages come with a satellite-based WiFi hub that will allow for your smartphone to work in locations that don’t have cellphone connections. Some satellite phone packages even allow for broadband access to the internet. The best satellite phones on the market keep you safe and connected.

When venturing off the beaten path, communication can mean the difference between smooth sailing and a rough misadventure. We looked at critical reviews and user recommendations, consulted outdoor enthusiasts and experts, and conducted heavy research to find the best satellite phones—because there’s comfort in knowing you can always call home.

What to consider when buying the best satellite phones

While satellite phones won’t replace your smartphone for everyday use, they step in and offer communication solutions for use when cellphone service isn’t possible. Sat phones are designed for international travel—but always check the countries’ policies ahead of time: is access allowed while off-the-grid camping and hiking or for use on boats or on recreational aircraft? The best satellite phones are designed with off-the-grid use in mind and should be rugged, waterproof, and durable. 

While connections are possible in all remote locations, the ability to receive signals can be hindered by buildings, roofs, shelters, or heavy tree coverage. Many manufacturers have solved this issue and offer packages that are designed to include antennas to use on the outside of structures or buildings, vehicles, boats, or even in the cockpit of an airplane. 

Use case

If you want to stay safe and connected when setting out for off-the-grid outdoor adventures, you will need a small, lightweight satellite phone that’s set up to offer all the features you need to stay safe. The best satellite communicator for wilderness adventures will be rugged, waterproof, and allow for easy messaging and an SOS distress call in case of emergency. 

Choosing a satellite communicator made for outdoor adventures means you’ll also have access to useful extra features. Companies like Garmin offer top-of-the-line GPS support, extra maps, topographic information, and safety advice for all types of rough terrain. Better brands offer excellent customer support as well as handy online resources.

Messaging vs. calling

When you travel or go on outside adventures, having a fully loaded SAT phone may not be necessary. Opting for a more basic satellite communication solution also means saving money. You’ve already got a smartphone—what you need is another layer of communication safety outside the cellphone zone. If you want to keep it simple, consider a satellite GPS messenger. These devices allow you to send messages to family and friends, letting them know you are safe, and also have important extra safety features like GPS location and SOS signals.

Text & voice calling bundles

The best satellite phone bundle will not only include a reliable, durable, easy-to-use phone, but it should also offer voice calling, text messaging, and email messaging. The best phones include a reliable large global network with 24/7 technical support. Packages should include all you need to use and get going without any additional purchases.

Helpful features to look for include different power adapters that allow for use in locations throughout the world. The best sat phone bundles also give you flexibility. You should be able to choose between a monthly plan or a prepaid SIM card—if you only use the phone a few months out of the year, you’re not stuck with a large monthly payment. 

International travel

Sat phones are a smart solution when traveling outside your home country. (Be sure to check the policies of the country you’re visiting before bringing one: They’re illegal in some places.) The best satellite phone for international travel is easy to set up and comes with a prepaid SIM card. That gives you the peace of mind that you can use the phone quickly no matter where you are without worrying about cellphone carriers or reception. Look for phones that offer reliable voice and call connectivity, as well as emergency signals. International travel often takes you to places where you can’t be sure what to expect, and a sat phone offers safety and protection, along with the security of knowing that you won’t be unreachable.


If satellite phone cost is a factor, consider a more basic satellite communication device. Fully loaded satellite phones can set you back around $1,000, not to mention the extra cost of SIM cards or monthly service plans. Economical solutions keep communication basic but also require a monthly subscription for service. 

The best budget satellite communicator allows you to text and receive texts, and some even offer apps that allow your phone to access the satellite Wi-Fi network. Always look for added emergency features such as SOS alerts and GPS coordinates.


Q: How much does a satellite phone cost?

Satellite phones and satellite communication devices range in price from $300 to over $1,000. In addition to hardware costs, you need a satellite provider to connect the phone for service and can purchase a monthly or prepaid plan from $100 to $5,000. Depending on your provider, voice calls range from $.0.15 to $2.00 a minute. Satellite calls between different satellite networks can be expensive. Review voice calls, text messaging, and incoming call costs with your selected provider.

Q: Are satellite phones illegal?

Satellite phones are not illegal in the United States, but in some countries, like China and Cuba, they are. It’s important to research and contact the government of any country you may be visiting to check their policies for use. Satellite phones have restricted use in some countries (e.g., Russia, India), and you must get permission to use these devices or risk arrest. Legal restrictions are in place to curtail any possible illegal or terrorist activities that depend on signals that can bypass censorship and wiretapping. 

Q: Can I turn my phone into a satellite phone?

It is possible to use your smartphone as a satellite phone by purchasing a SatSleeve (Satellite Sleeve) and installing the SatSleeve App. The first time you use your SatSleeve, you have to set it up to connect via Bluetooth. Some satellite providers (like Iridium Go!) offer packages that include a satellite phone and a satellite phone hotspot that allows you to connect your smartphone, tablet, or laptop to a satellite-backed WiFi hotspot. 

Q: Do satellite phones run out of batteries?

Yes, but satellite phone batteries can last much longer than a phone battery. Putting your phone in Standby mode can help stretch the amount of time between charges. If you’re really worried about run time, consider bringing a portable charger or extra phone battery to swap out just in case.

Q: Do satellite phones have a monthly fee?

Yes. Some brands also offer prepaid plan, but we recommend a monthly service. Some plans provide you with rollover minutes, uninterrupted service, and even a U.S. phone number. Prepaid plans can be more expensive, offer a limited amount of minutes, and no options for rollover minutes.

Final thoughts on the best satellite phones

The best satellite phones will allow you to roam around the globe and stay connected. With rugged, waterproof designs, these phones can follow you on any adventure by land, sea, or air. Connect with a prepaid SIM card, or with a monthly plan to keep safe and communicate no matter where you are. In case of emergency, sat phones will send SOS signals and GPS coordinates to make sure you return home safe. Compare phones, then get shopping.
