Buying Guide: What to Look For in a Satellite Phone

When I started looking for a satellite phone, I quickly realized it wasn’t as simple as picking a new smartphone. The stakes are higher because you’re buying this device for situations where regular communication fails. My first piece of advice is to forget about fancy screens and apps; here, reliability is king. You need to think about which satellite network you’ll be using. The big players are Iridium, Globalstar, and Inmarsat. Iridium has the most comprehensive global coverage, including polar regions, which is great for truly remote expeditions. Globalstar is often praised for its call clarity in its coverage zones, while Inmarsat is a long-standing leader for maritime and fixed-location use. Your primary operating area will heavily influence this choice.

Next, consider the device’s core functionality. Do you just need to make voice calls and send basic SOS alerts, or do you require data for email and basic web browsing? Most sat phones offer slow data speeds by modern standards—think early 2000s dial-up—but it’s enough for critical messaging. If your needs are more about sending your location and pre-set messages, a satellite messenger like a Garmin inReach or SPOT device might be a more compact and affordable option. However, for real-time, two-way voice conversation, a dedicated sat phone is irreplaceable.

Durability is non-negotiable. I always look for devices with IP ratings (Ingress Protection) that guarantee resistance to dust and water. An IP67 rating, for example, means it can survive being submerged in water for a short time. Military-grade shock resistance (MIL-STD-810) is another good sign that the device can handle being dropped or jostled in a pack. Battery life is another critical factor. Manufacturers often list “standby time,” but you should focus on “talk time.” In a real-world scenario, you might get significantly less than advertised, so I recommend looking for a phone with a long-lasting battery and considering purchasing a spare.

Finally, don’t forget the ongoing costs. A satellite phone is often just the initial investment. You’ll need an active service plan. These can range from prepaid, pay-as-you-go minutes, which are perfect for occasional use, to monthly subscription plans that are more cost-effective if you use the phone regularly. Be sure to research the cost of airtime minutes and data in the regions you plan to visit. Some networks have much higher rates in certain countries. Getting the right device and plan for your specific needs is the most important part of this 10 satellite phone buying guide.

Frequently Asked Questions

How much does a satellite phone and its service actually cost?

This is the first question I had, and the answer has two parts. The handset itself can range from around $500 for a basic, older model to well over $1,500 for a latest-generation device with extra features. The service plans are the recurring cost. Prepaid plans can start as low as $50 for a bundle of minutes that expire in a year. Monthly subscription plans typically range from $30 to $100+ per month, which includes a set number of minutes. Data is almost always billed separately and can be expensive, so it’s crucial to budget for both the hardware and the ongoing service.

Can I use a satellite phone indoors or under a tree canopy?

Almost never. Satellite phones require a direct, unobstructed line of sight to the sky to connect to the satellites. Thick tree cover, buildings, mountains, and even being inside a vehicle can block the signal. For the best performance, you need to be in a large, open area. Some devices have port options for an external antenna, which can be mounted on a vehicle or a building to get a clear view, but the handset itself needs to be outside.

Are satellite phones legal to use anywhere in the world?

Not exactly. While the technology is global, many countries have strict regulations governing the use of satellite phones. Some nations, like India, China, and Nigeria, heavily restrict or outright ban their use without special permits. It is absolutely your responsibility to check the local laws of any country you plan to visit before you take your satellite phone there. Using one illegally can lead to confiscation, heavy fines, or even detention.

How is a satellite phone different from a satellite messenger?

This is a key distinction. A satellite phone, like an Iridium 9575 or an Inmarsat IsatPhone 2, is designed primarily for two-way voice calls, similar to a traditional cell phone. A satellite messenger, like a Garmin inReach or Zoleo, focuses on two-way text messaging, sending SOS signals, and sharing your GPS location. Messengers are typically smaller, lighter, and have much longer battery life, but they don’t allow for real-time voice conversation. Your choice depends on whether you need to talk or if messaging and SOS are sufficient.

Do I need a special number for my satellite phone?

Yes, satellite phones have their own unique international telephone numbers, which are different from standard cell phone numbers. An Iridium phone, for instance, has a number starting with +8816. People calling you from a landline or cell phone will be making an international call, which might be expensive for them. It’s often more practical for you to be the one initiating the calls from the satellite phone to keep costs manageable for your contacts.
