Ten years ago, we carried very few electronic devices into the mountains. Only on long, remote trips was it common to bring a GPS, and not much more. Today, however, having a satellite communication device has become essential for those of us who venture beyond conventional trails. Although no one plans to press the SOS button, two-way communication has proven to be key to the success and safety of our expeditions.
If you carry a satellite communication device, it is crucial to update your plan and emergency contacts before every trip. That said, it's worth noting that trip planning and self-rescue preparedness are even more important than simply carrying an SOS device. But that's a topic for another blog post.
Today, at the request of the Backcountry Cooperative community, we'll explore some of the best satellite communication options available on the market.
Satellite Communication Device Options
Satellite Emergency Notification Devices (SEND)
SEND devices include brands such as SPOT, Garmin inReach, satellite phones and other satellite messengers. These devices work through paid subscription services, and their features vary:
- Some, like SPOT, offer SOS and limited preset messages.
- Devices like Garmin inReach allow two-way messaging, in addition to the SOS function.
- Satellite phones allow voice calls and text messages.
When an SOS signal is activated, it includes the location and identification of the device. The alert is transmitted to GEOS (an emergency response center), which coordinates the rescue with the nearest resources.
Satellite Network Coverage
There are two main satellite communication networks:
- Globalstar (used by SPOT): limited coverage, especially in Arctic areas.
- Iridium (used by inReach and some satellite phones): full global coverage.
If you're planning an expedition in remote regions, the Iridium network is the best option.
Comparison: SPOT vs. inReach
The main difference between the two devices is that SPOT uses Globalstar and inReach uses Iridium. In addition, inReach has a much more user-friendly and versatile interface, with advanced features and a growing user community.
Satellite Phones
Satellite phones work on both networks (Globalstar and Iridium), but they have some drawbacks:
- High price (generally > USD 1,000)
- Bulky size and heavy batteries
- Expensive subscription rates
- Frequent signal loss in certain areas
For recreational use, or even professional use as a guide, we do not recommend buying a satellite phone because of these factors. However, an interesting option is the Iridium Go! (USD 800), which turns a smartphone into a satellite phone.
The Evolution of Garmin inReach
Originally made by DeLorme, inReach devices were acquired by Garmin in 2016. Since then, they have evolved considerably:
- DeLorme inReach SE: SOS and messaging with excellent battery life.
- DeLorme inReach Explorer: Adds GPS functions with higher battery consumption.
- Garmin inReach SE+: Improved version of the Explorer, with a rugged casing.
- Garmin inReach Explorer+: Full GPS with base maps and importable/exportable routes.
- Garmin inReach Messenger: Pairs with smartphones and supports messages of up to 1,600 characters.
If you're looking for the best satellite communication device, the Garmin inReach Explorer+ is one of the most highly recommended options.
9 Basic Tips for Setting Up Your inReach
If you already have a Garmin inReach, make sure to follow these steps before every trip:
- Download the app compatible with your device.
- Pair the app with your inReach.
- Check your subscription plan.
- Review your account settings.
- Organize your mapping options.
- Sync updates to your device.
- Practice using the inReach before the trip.
- Test the device to confirm it works properly.
- Check support resources if you have questions.

Rescue Resources in Patagonia
Rescues in Patagonia can involve public and private resources, including:
- Search and rescue teams
- Helicopters
- Gendarmería and ICE
The rescue deployment hierarchy is usually:
- Private resources (Global Rescue, LifeMed, IBEX Heli)
- State resources (Gendarmería, ICE, Army)
- Volunteer teams (CAX)
In Bariloche, one company now offers rescue insurance with helicopter transport. IBEX has an annual plan of 198,000 ARS (January 2025) or 36,000 ARS/month, covering a radius of 200 km around Bariloche. More info at IBEX Heli.
From Garmin, you can also purchase annual insurance for USD 40, with rescue coverage of up to USD 100,000.
