Buying Guide: What to Look For in a Satellite Phone
When I started looking into satellite phones, I quickly realized it’s not like picking a regular cell phone. The stakes are higher, and the costs are different. My main goal was to understand what I was actually paying for and which device wouldn’t let me down when I needed it most. This guide breaks down the key things I consider: cost, service plans, and the best brands available right now.
First, let’s talk about the biggest factor: the network. You’re not buying just a phone; you’re buying into a satellite constellation. The two main players are Iridium and Inmarsat (now part of the Viasat family). Iridium has a network of 66 cross-linked satellites, which means it offers true global coverage, including poles and oceans. Inmarsat’s geostationary satellites provide strong coverage over most of the world but can have trouble in extreme northern or southern latitudes. Your primary travel or operational areas will dictate which network is best for you.
Next up is the device itself. The initial hardware cost can range from a few hundred to over a thousand dollars. I look at phones like the Iridium 9575 Extreme as a rugged, go-anywhere tool, while something like the IsatPhone 2 is known for its reliability and long battery life. For a more hybrid approach, devices that use the Iridium or Globalstar networks, like some from Garmin or SPOT, offer satellite messaging and SOS features without the full voice capability, which can be a great cost-saving option if you don’t need constant voice communication.
But the phone is only half the story. The service plans are where the ongoing cost comes in. I’ve seen two main types: monthly plans and prepaid airtime. Monthly plans are great if you know you’ll use the phone regularly. They often include a bundle of minutes that expire each month. Prepaid airtime is perfect for occasional users; you buy a block of minutes that are valid for a year or more. I always check the per-minute rate for calls and the cost for SMS messages, as these can vary wildly. Don’t forget to check the coverage maps for your specific plan, as some cheaper plans might not include all regions.
Finally, I think about the physical attributes. Durability is non-negotiable. I look for MIL-STD-810 ratings for shock, dust, and vibration, and IP ratings for water resistance. Battery life is another critical spec—advertised standby time is one thing, but I pay closer attention to the rated talk time. A phone that lasts for 30 hours on standby is useless if it only has 4 hours of talk time for a multi-day trip. By weighing the network, device cost, service plan structure, and physical toughness, you can find the right tool for your needs without overpaying. This 10 satellite phone guide on cost, plans, and best brands available now should set you on the right path.
Frequently Asked Questions
How much does a satellite phone plan actually cost per month?
This is the question I asked most when I started. The cost isn’t straightforward. For a basic Iridium or Inmarsat voice plan, you might find options starting around $30 to $50 per month. However, this usually only includes a very small number of minutes, sometimes just 10-15. If you need more substantial usage, expect to pay between $100 and $200 per month for plans with 100-200 minutes. Prepaid plans are different; you might pay $150 for a 100-minute card that is valid for a full year, which breaks down to a much lower monthly cost if you’re an occasional user. Always read the fine print on minute expiration and overage rates.
Can I use a satellite phone anywhere in the world?
Most major networks offer near-global coverage, but “near-global” is the key term. Iridium is your best bet for true pole-to-pole coverage, including the middle of oceans. Inmarsat’s coverage is excellent over most populated land masses and shipping lanes but has significant gaps in the Arctic and Antarctic. It’s absolutely crucial to check the coverage map for the specific network and plan you’re considering. Also, remember that you need a clear view of the sky. Using a sat phone indoors, under heavy tree cover, or in deep urban canyons is impossible.
Are satellite phones difficult to use?
Modern satellite phones are much more user-friendly than they were a decade ago, but they are not smartphones. The interface is usually simpler, and making a call requires a few more steps. You have to point the antenna toward the satellite (for geostationary systems like Inmarsat) or simply find a clear view of the sky (for Iridium). Dialing includes using the correct international format, like +1 [area code] [number] for the US. There’s also a slight delay in the conversation due to the signal traveling thousands of miles to space and back. It takes a little practice, but it’s not difficult to learn.
What is the difference between a satellite phone and a smartphone with satellite connectivity?
This is a vital distinction. A dedicated satellite phone, like an Iridium or Inmarsat model, is designed solely for satellite networks. It’s a standalone device for reliable voice calls and basic SMS anywhere. A smartphone with satellite features, like certain iPhones or Android devices, uses a different technology. Currently, these are primarily for emergency SOS messaging and short text-based services. They are an incredible safety net, but they are not a replacement for a true sat phone if you need to have a full conversation or conduct regular business from a remote site. This 10 satellite phone guide on cost, plans, and best brands available now focuses on dedicated voice devices.
Do I need a special license to operate a satellite phone?
In most countries, no, you do not need a special license for personal use. The service provider handles the necessary licensing with the satellite operator. However, some countries strictly regulate or even prohibit the import and use of satellite phones. It is your responsibility to check the local laws of any country you plan to visit or operate in. Using a sat phone in a country where it is banned can lead to confiscation of the device, heavy fines, or even legal trouble.
