The top satellite phones and gadgets for reliable off-grid communication

Do you want a phone that works anywhere? Get a sat phone. I've played with and looked into the best satellite phones -- ones that offer SOS, GSM network capabilities, and global coverage -- and here are my top picks.

Do you travel frequently and often find yourself "off the grid," or are you someone who enjoys going on adventures but still needs to stay connected? If so, forget about smartphones and consider a satellite phone.

Although referring to it as a "sat phone" may add to the secret agent vibe, these phones are more widely available than you might think, and there are several options to choose from.

Keep in mind that a subscription is required to access a satellite network, and prices vary depending on the network used, the type of service needed, and the length of the subscription. Additionally, note that prices are much higher than those for cellular networks and can reach exorbitant levels

What is the best satellite phone?

It's less a question of which is best for me, and more which is best suited to you. Three factors in particular come into play: What you need it for, the price, and the network. To demonstrate, if you want an affordable phone that has global coverage capabilities, the Garmin inReach Mini 2 fits the bill. Meanwhile, if you want a satellite phone that can switch from GSM to satellite easily, the Thuraya XT-LTE is a wise choice.

Note: Prices and availability may vary.
As you can see, each satellite phone has its own unique features, benefits, and drawbacks. Ultimately, the best satellite phone for you will depend on your specific needs and preferences. When making a decision, consider factors such as price, satellite network, global coverage, features, durability, and battery life.

Which is the right satellite phone for you?

When it comes to selecting a satellite phone, there are various options available in the market. However, selecting the right one depends on your requirements and priorities. It's essential to prioritize why you need the phone and your budget. This will help you to select the best phone at the best price, and more importantly, you'll have a communication tool that works where you are when you need it the most. Below are the key considerations and how each phone aligns with specific purposes:

Choose this best satellite phone...

If you want... 

Iridium Go!

Global coverage and the ability to create a hotspot for multiple devices. The Iridium Go! is the best choice because it offers satellite calls and SMS, has good battery life, and is MIL-STD 810F certified for durability.

Spot X

Something for occasional use or emergency situations. The Spot X is a good choice because it t has an SOS feature and is low-cost. However, it has limited features and a small physical keyboard.

Garmin inReach Mini 2

Occasional satellite communication and SOS support. The Garmin inReach Mini 2 is ideal because it is affordable, lightweight, and offers a range of features such as two-way messaging, interactive SOS, and TracBack routing.

Thuraya XT-LTE

A satellite phone that also acts as a smartphone. The Thuraya XT-LTE is the best option because it has both satellite and GSM capabilities and is rugged, making it ideal for outdoor activities. However, it doesn't offer global coverage and has a limited battery life.

Inmarsat IsatPhone 2.1

A classic satellite phone with global coverage.  The Inmarsat IsatPhone 2.1 offers voice calls, SMS, GPS tracking, and a programmable emergency assistance button. However, it is big, bulky, and expensive.

How did I choose these satellite phones?

When selecting the best satellite phone, I personally tested some of the devices and took into consideration other devices and various factors, such as price, availability, coverage, and use case. I carefully analyzed each device and weighed the pros and cons before arriving at my conclusions.

  • Price: Cost is always a factor, especially for those who are going to use their satellite phone only occasionally.
  • Availability: No point listing something that's not in stock!
  • Coverage: Not all satellite networks offer global coverage, so knowing this in advance is important.
  • Use case: Are you looking for a traditional satellite phone, or do you want something more specialized like a satellite hotspot or emergency beacon?

What is a satellite phone?

A satellite phone is a mobile device that uses satellites to communicate instead of cell towers. It allows users to make calls and send messages from virtually anywhere in the world, including remote areas without cell coverage.

How much do satellite phones cost?

Satellite phones can range in price from a few hundred to several thousand dollars, depending on the features and capabilities of the device. Service plans also vary in cost depending on the provider and coverage area.

Isn't the iPhone 14 a satellite phone?

Well, sort of.

Apple has added a feature called Emergency SOS via Satellite which allows owners to contact emergency services when in an area without cellular or Wi-Fi coverage. 

Review: The iPhone 14 is exactly as good as it needed to be 

Emergency SOS via satellite is free for the next two years. After that Apple plans to start charging for the service, although right now we don't have a price. 

This service is currently available in the US, Canada, and most of Western Europe. 

Can a satellite phone replace a smartphone?

Not really. They're big, bulky, expensive, and the data rates are awful compared to even 3G. However, they do offer services that regular smartphones cannot match.

If you're an avid hiker or camper, you know how remote areas don't have the best cellular service. This is where satellite phones come in handy: they give you access to communication in areas cellular companies don't.

Which satellite network is the best?

It's less about which is best and more about what bits of the planet you want coverage on. Every network offers maps and details of coverage. Keep in mind not all networks offer global coverage. 

And it's advisable to check this at the time of purchase because coverage can (and does) change regularly. Doing this ensures you have the right phone and network for where you're requiring it. 

Can you get a satellite phone that doubles as a regular phone?

Satellite phones, like the Thuraya XT-LITE, offer features that you typically find on cellular phones, such as calling and messaging. While the Thuraya XT-LITE does not offer global coverage and both North and South America are not covered, it has a unique ability to toggle between a GSM network and satellite communications. This means that you won't have to worry about dropped calls in remote locations. Plus, the phone only requires one SIM card. Additionally, it has a rugged body, making it a durable option for outdoor adventures. However, satellite phones still have some drawbacks compared to smartphones, such as bulkiness and limited data rates.

How reliable are SOS devices such as the SPOT X of Garmin inReach?

Based on my personal experience, satellite phones are highly reliable and serve as a great insurance policy for individuals heading out into remote and uncharted territories. Since they operate on satellite communication, they offer a wide range of coverage that is not available with cellular service, especially in mountainous regions or areas with limited network coverage. However, it's important to note that satellite devices do have some limitations, such as slower communication speeds than smartphones. Therefore, it's important to keep this in mind when planning for emergency situations or other time-sensitive communication needs.

Are there alternative satellite phones worth considering?

We chose a variety of worthy options. Here are several others to consider: 

ZOLEO Satellite Communicator is a great alternative satellite phone to consider because it allows two-way global messaging with a compact design.

Garmin Montana 700i is an alternative satellite phone to consider because it combines GPS and GALILEO satellite networks with inReach technology, providing a reliable and versatile communication and navigation tool.

COM IC-SAT100 is a rugged satellite phone alternative that utilizes the Iridium satellite network, making it an excellent choice for those who need reliable communication in harsh environments.
