The Best Satellite Messengers For Your Adventures

Subscribe to Iridium360:


With summer approaching, your pals at Iridium have created this handy, carefully-curated list of the best personal satellite messengers. Whether you’re climbing, biking, distance running, kayaking, backcountry camping, or just chillaxin’ in the deep woods, this suite of Iridium Connected™ solutions ensures you’ll maintain communications no matter how far you venture off the grid. Every product on this list communicates over the Iridium satellite network.


Why are Iridium Connected Satellite Messengers the Best?

They’re Reliable

Our network uses L-band satellite spectrum–giving end users a weather-resilient experience, which is invaluable for the outdoor, extreme sports, and adventure traveler communities. Additionally, the network is located in Low Earth Orbit (LEO), delivering a low-latency (or minimal delay) two-way communications experience.


They Have Unmatched Coverage

Every Iridium satellite is connected to its neighbors by crosslinks, creating a coverage web around the entire planet. Iridium remains the only satellite network that offers truly global coverage.


The Battery Life

The devices below can hold a charge for long stretches of time–with many providing hundreds of hours per charge.



When people think satellite communications, they think big bucks. However, because Iridium satellite messengers are small, lightweight, and have comparatively low power requirements, they are often more cost-effective than competing products with bigger antennas and greater power needs. There are also customized subscription plans available based on data needs to help manage budgets without having to sacrifice service quality.
