Satellite communicators solve the problem of being genuinely out of reach — no cellular signal, no Wi-Fi, no way to contact anyone. The right device depends on five decisions made in order.
- 1
Choose a satellite network
Two networks power almost all consumer satellite communicators: Iridium (66-satellite constellation, 100% global coverage) and Globalstar (partial coverage, strong in North America). Garmin inReach, Zoleo, Bivy Stick, Somewear, and Iridium GO! exec all use Iridium. SPOT Gen4, SPOT X, and SPOT Trace use Globalstar. For North American hiking, either works. For international or polar travel, Iridium is the reliable choice.

Two-way communicator or PLB?
A PLB transmits a one-way distress signal to government rescue services — no subscription fee, no messaging, no tracking. A satellite communicator adds two-way messaging, routine location sharing, and non-emergency communication at a monthly cost. If the only goal is emergency signaling: a PLB. If communicating with family and contacts on non-emergency trips matters: a satellite communicator.

Standalone or phone-dependent?
Phone-dependent communicators (Garmin inReach Messenger, Bivy Stick, Somewear) use the phone for messaging interface, GPS, and SOS triggering. They are lighter and often cheaper. The risk: a dead phone disables them. Standalone devices (inReach Mini 2, Explorer+, SE+) work independently of a phone. For reliable phone battery management: phone-dependent is practical. For trips where a dead phone is a real risk: standalone provides fewer failure modes.

Budget for subscription cost
The device purchase price is only part of the cost. Monthly plans range from $12-15/month (basic, limited messages) to $50-65/month (unlimited messaging and tracking). Annual plans and pause options reduce costs for seasonal users. Over two years, a $200 device with a $30/month plan costs $920 total; factor this into comparisons.

Decide if navigation matters
Most satellite communicators provide GPS location and basic waypoints. Only the Garmin Explorer+, GPSMAP 66i, and Montana 700i include downloadable topographic maps for full offline navigation without a phone. If a phone handles all navigation reliably: any device works. If a backup navigation device independent of phone battery is needed: the Explorer+ is the appropriate choice.
