The fact that nature is beautiful can’t be disputed. However, the old saying “every rose has its thorn” contains truth as well. Even relatively tame natural parks can be as deadly as they are awe-inspiring. In fact, according to the National Parks Service, over 140 people died in American national parks in 2014. The main causes of accidental death in parks include drowning, falls, avalanches and exposure to extreme temperatures. Emergencies caused by these kinds of accidents become complicated when communication options are limited.
Satellite messengers provide a low-cost, easy-to-use option for not only summoning help when required, but also staying in touch with loved ones while you’re adventuring. Navigation is another use case for GPS-capable satellite messengers. Some are even equipped with social media features that let you show off your progress to your friends and family. Another benefit of satellite messengers is that they’re usually more rugged, weather resistant and energy efficient compared to standard consumer-grade smartphones.
Here are the best satellite messengers you can buy:
The most user-friendly satellite messenger
Garmin inReach Explorer+
The best thing about the Garmin inReach Explorer+ is that it’s easy to use. Maps are preloaded, so you don’t have to pay extra for a map subscription and wait for them to download. Other features– like the handy weather forecast utility and the Earthmate app— enhance its usability, as well.
- Intuitive interface. The compass screen displays your exact coordinates, which you can automatically post to social media so that your friends and family know where you are at all times.

In a nutshell
Ease of use is the inReach Explorer+’s most distinguishing feature. The menus are intuitive and you’ll be able to flip through them effortlessly as soon as you turn on the phone. All its maps come preloaded, so you don’t have to wait for them to download or pay an additional monthly fee to use them.

Some excursions require you to squeeze every bit of space you can out of your backpack. That’s where Garmin’s InReach Mini comes in. It’s just four inches tall and two inches wide.

In addition to your coordinates, the maps display satellite images of surrounding terrain. The built-in altimeter, barometer and compass sensors add even more data to its maps.
The best low-cost satellite messenger
What the Spot 3 lacks in advanced features it makes up for in ruggedness and affordability. Interestingly, it doesn’t have a screen– but this downside is an advantage when it comes to battery efficiency. It runs on standard AAA batteries and programmable buttons let you do things like send out prewritten text messages, post check-ins, signal for help and more.
- Low price. Affordability is one of the Spot 3’s main selling points.

The Spot 3 doesn’t have any kind of display, but it can send out prewritten text messages and post GPS check-ins to the internet. The rubber-coated exterior makes it tougher than the average satellite messenger. Because it runs on standard AAA batteries, it may be the best option for long trips that take you deep into dangerous off-the-grid locations.
The best smartphone-compatible satellite messenger
The Bivystick lets you turn any standard smartphone into a satellite messenger. It connects you to the Iridium satellite network, which lets you communicate from nearly any part of the planet.

Buying guide for satellite messengers
Different satellite messengers use different satellite networks, and some of them have better worldwide coverage than others. Check which network your device uses before you buy so that you can be sure that it will work in the off-the-grid area where you intend to go.
Battery type and capacity
Most satellite messengers have built-in batteries and you can’t recharge them if you don’t have an adapter and access to wall power. Others run on standard replaceable batteries. If you intend to remain off-the-grid for an extended period of time, the second type is more ideal.
Durability and water resistance
Satellite messenger manufacturers advertise various military and IP (Ingress Protection) ratings. Typical satellite messengers are watertight enough to resist rain, or IP65 compliant. If you need additional protection against complete water immersion, get a satellite messenger that meets the IP66 or IP67 standards.
GPS availability and precision
Just because a satellite messenger can send messages doesn’t necessarily mean that it’s GPS-capable. Moreover, some GPS receivers are more sensitive than others. If you plan on using your messenger for navigation, be sure to get one that has a high quality GPS receiver.
Display size and type
Messengers with large, brightly-lit displays are much easier to read. On the other hand, the bigger the display is, the more battery power it will consume. Some messengers don’t have a display at all. These tend to be more rugged, but they also lack the features found in messengers that have displays.
This feature lets you establish a communication line with an emergency rescue service. You can usually configure the button so that it messages the contact of your choice. Most but not all satellite messengers are equipped with an SOS button, so make sure yours has this feature before you buy if staying safe in the wilderness is your primary need.
Sensor number and type
Navigation-oriented satellite messengers are equipped with sensors that collect various kinds of data. Messengers with altimeters can measure your height, while messengers that have built-in barometers can predict short-term weather changes.
Location tracking lets you not only show off your progress, but also gives your loved ones an easy way to know that you’re safe. Messengers that are equipped with location tracking features can send updates via SMS, email or even social media.
Some messenger manufacturers make you pay extra to download maps or pay a monthly fee for map service, while others provide free preloaded maps. You can get a better idea of how much your messenger will cost you if you find out these details before you make your purchase.
Screenless satellite messengers are the best option if you’re on a budget. You can also use them to back up your other communication devices. They tend to be more rugged and weather-resistant compared to more feature-rich messengers. Expect to pay about $100.
For about $400, you can find satellite messengers that can do things like send out automatic updates. Most messengers in this category are equipped with basic navigation features.
Full-featured satellite messengers that cost $600 or more have advanced navigation features, like full-color satellite maps, for example. They also tend to be more rugged compared to mid-range messengers.
Frequently asked questions
Q: What kind of messages does a satellite messenger send?
A: Since satellite networks can connect to the internet, a wide variety of kinds of messages are possible. You can send out emails, post your latitude and longitude to the internet and even create automatic social media updates. However, low bandwidth is an important limitation to be aware of before you make your purchase. You shouldn’t expect to be able to send or receive videos, for example.
Q: Do you need a subscription to use a satellite messenger?
A: Yes. Plans vary depending on the brand. Most satellite messengers offer monthly and one-year service plan options. Most monthly plans are more expensive. You can usually get some kind of discount by paying for a year or more of service in advance.
Q: What’s the difference between a satellite messenger and a satellite phone?
A: The main difference is voice communication. Satellite messengers are kind of like fancy pagers. You can use some of them for navigation, but direct voice communication is not part of the feature lineup. High-end satellite phones are equipped with all the features you’d find in a messenger, like navigation, SMS, email support, etc.
- One way to conserve your satellite messenger’s battery is by using it only when you have a clear view of the sky. When there’s clouds, it’ll have to work harder to push your messages to and from its satellite network.
- Before you venture out into the wilderness with your satellite messenger, test it out by sending a message to your smartphone. You don’t want to discover there is an issue with your service or some other kind of technical issue after it’s too late to do anything about it.
- Read the fine print and identify all the fees your satellite messenger service will charge. You may find maintenance fees that aren’t advertised in the promotional materials.
