Buying Guide: How to Choose Your Satellite Phone
When you need to stay in touch from the most remote corners of the planet, a standard cell phone just won’t cut it. That’s where satellite phones come in. I’ve spent a lot of time figuring out which gear is reliable, and choosing the right one isn’t just about picking the shiniest model. It boils down to a few key factors that will determine whether your device is a lifeline or a paperweight.
First, you need to think about the network. This is the most critical decision. The two main players are Iridium and Inmarsat (now part of the Viasat family). Iridium’s network has a constellation of satellites that crisscross the poles, offering truly global coverage, including the poles and open oceans. If you’re an adventurer heading to extreme latitudes, this is your best bet. Inmarsat’s geostationary satellites provide excellent coverage over most of the Earth, but they can struggle in deep canyons or at the very highest and lowest latitudes. Globalstar is another option, but its coverage is more regional, so check their maps carefully.
Next, consider the device itself. Are you looking for a rugged, pocket-sized handset for voice calls and basic SMS, or do you need a terminal for faster data? For most people, a handheld like an Iridium 9575 Extreme or an IsatPhone 2 is perfect. They are built to survive drops, water, and dust. If you need to connect a laptop or set up a small remote office, you’ll want a terminal like a Viasat BGAN or Iridium Certus device. These offer much faster data speeds for email and web browsing, but they are larger and more expensive.
Don’t forget about the cost structure. Satellite communication is not cheap. You have the upfront cost of the phone or terminal, and then the ongoing service plans. Plans can be prepaid, where you buy minutes in blocks, or monthly subscriptions. Think about your usage pattern. If you only need the phone for emergencies, a prepaid plan with a long expiration is sensible. If you’ll be using it regularly for work, a monthly plan might be more cost-effective. Always factor in the cost of airtime per minute for calls and per megabyte for data—it can add up quickly.
Finally, look at the practical features. Battery life is huge. How long can the phone last on a single charge, especially on standby? A five-day standby time is a good benchmark. Also, check for essential accessories like external antennas for better signal reception in tricky spots, car chargers, and durable cases. Making the right choice in a satellite phone ensures you have the best connectivity anywhere on Earth today, giving you peace of mind when you’re far off the grid.
Frequently Asked Questions
How reliable is satellite phone service in bad weather?
This is a common concern. While satellite signals can be affected by very heavy rain, snow, or thick storm clouds (a phenomenon called rain fade), the service is generally quite robust. The higher frequency Ka- and L-bands used by networks like Iridium and Inmarsat are designed to punch through most weather. In my experience, you might experience a slight degradation in signal quality or a temporary drop during the absolute peak of a severe storm, but for the most part, the connection holds. It’s far more reliable than having no signal at all, which is the alternative in these remote locations.
Can I use a satellite phone inside a building or a car?
Generally, no. Satellite phones need a clear line of sight to the sky to connect to the orbiting satellites. Even a thin roof, a car roof, or dense tree cover can block the signal. To use one inside a building, you would need to be near a window, and even that isn’t a guarantee. For use in a vehicle, you need an external antenna mounted on the roof or hood that is connected to the phone. This is a popular setup for overlanding and remote work trucks. For the best results, I always step outside into an open area to make a call.
Are satellite phones legal to use anywhere in the world?
Not exactly. While satellite phones are legal in most countries, some nations strictly regulate or outright ban their use. Countries like India, China, Russia, and Nigeria have restrictions, often due to security concerns. It is absolutely your responsibility to check the local laws of any country you plan to visit before you bring and use your device. Using a sat phone in a country where it’s prohibited can lead to confiscation of the device, heavy fines, or even more serious legal trouble. A quick check with your service provider or the country’s embassy before you travel can save you a massive headache.
How does the call quality compare to a regular cell phone?
You will notice a difference. Because the signal has to travel thousands of miles to a satellite and back, there is a noticeable delay, or latency, in the conversation. It’s usually about a half-second lag. This means you need to avoid talking over the other person and pause slightly after they finish speaking. The audio quality itself can also be a bit more robotic or compressed compared to a modern cellular VoIP call. However, the technology has improved dramatically, and for a vital call from the middle of nowhere, the quality is more than acceptable.
What happens if I need to make an emergency call?
This is a crucial point. Unlike cell phones, satellite phones do not automatically connect to a local emergency service number like 911. You must dial the international satellite emergency number for the service you are using. For Iridium, it’s +1 480 768 2500. For Inmarsat, it’s +870 776 231 030. I strongly recommend saving these numbers in your phone’s contacts before you head out. It’s also a very good idea to have a backup plan, such as a Personal Locator Beacon (PLB) or a device with an integrated SOS function, like a Garmin inReach, which is specifically designed for emergency distress signaling.
