Buying a Satellite Phone — What You Need to Know

A satellite phone keeps you connected where mobile networks can't reach. Whether you're heading offshore, trekking through northern Scandinavia, or preparing an emergency kit for your boat, a sat phone is the most reliable way to call and send messages from anywhere on earth.

But which one should you pick? There are three major networks, dozens of handsets, and big differences in coverage, call quality, and price. This guide breaks it all down.

The Three Satellite Networks

Iridium — Global Coverage

Iridium's 66 satellites cover every square meter of the planet, including the poles. If you need guaranteed coverage everywhere, Iridium is the only choice. The Iridium 9575 Extreme is the most popular handheld, and the IridiumGO! exec turns your smartphone into a sat phone with data and SOS.

Thuraya — Best Voice Quality

Thuraya covers Europe, Africa, Asia, and Australia with excellent voice clarity. If you stay within their coverage map, you'll get a phone that feels closer to a regular mobile. Thuraya handsets are often lighter and more affordable than Iridium equivalents.

Inmarsat — Data and Maritime

Inmarsat's geostationary satellites deliver higher data speeds, making them ideal for vessel tracking, email, and weather downloads at sea. The IsatPhone 2 is a solid handheld option for areas within Inmarsat's coverage.

What to Consider Before You Buy

• Coverage area: Will you travel above 70°N? Only Iridium works at the poles.
• Voice vs. data: Need just calls and SMS? A handheld works fine. Need email and charts? Look at the IridiumGO! or a satellite modem.
• SIM and airtime: Prepaid SIMs work great for occasional use. Monthly plans make sense for daily users.
• Battery life: Iridium 9575 lasts about 4 hours of talk time. Consider a backup battery for longer trips.
• Durability: The Iridium 9575 is IP65 rated and MIL-STD 810. Thuraya handsets are more consumer-grade.

Frequently Asked Questions

Do satellite phones work indoors?

Generally no. Satellite phones need a clear view of the sky. You can use an external antenna to improve reception from inside a cabin or wheelhouse.

How much does it cost to call with a satellite phone?

Airtime ranges from about $0.80 to $1.50 per minute depending on the network and plan. Prepaid packages start around $100 for 75 minutes.

Can I use a satellite phone in Sweden and Norway?

Yes. Satellite phones are legal and fully usable across all of Scandinavia. No license required.

What's the difference between a satellite phone and a PLB?

A PLB (Personal Locator Beacon) sends an emergency distress signal but can't make calls or send messages. A satellite phone gives you two-way communication plus the ability to call rescue services directly.
