Your phone GPS works without cell service—but if you break your phone or the battery dies, you have no navigation and no way to call for help. A dedicated GPS or satellite messenger is the backup that saves lives.
| Device | Price | Subscription | Weight | Battery | Key Feature |
|---|---|---|---|---|---|
| Garmin inReach Mini 2 | $400 | $12/month | 3.5 oz | 14 days (30-min tracking) | SOS + 2-way texting via satellite |
| Garmin GPSMAP 67i | $600 | $12/month | 8.1 oz | 180 hours | Full mapping + inReach satellite messaging |
| ZOLEO Satellite Communicator | $200 | $20/month | 5.3 oz | 200 hours | Best price, dedicated SMS number |
| SPOT X | $250 | $12/month | 7 oz | 240 hours | Built-in QWERTY keyboard |
The inReach Mini 2 sends two-way text messages via the Iridium satellite network—the only network with truly global coverage (poles included). From any location on Earth with a clear view of the sky, you can text family ("camping at Trout Lake, all good") or press the SOS button to contact GEOS Emergency Response (Garmin's 24/7 monitoring center). The SOS triggers a rescue—helicopter, search and rescue team, or local emergency services—at your exact GPS coordinates. The two-way messaging is critical because GEOS texts back to confirm the SOS was received, ask about the nature of the emergency (injury? lost? weather-trapped?), and provide an ETA. One-way devices (older SPOT) leave you wondering if anyone received your SOS. At 3.5 oz, it lives in the bottom of a pack or on a shoulder strap—always accessible, even if you are injured and separated from your pack. The TracBack feature drops virtual breadcrumbs and guides you back to the trailhead if you are lost.
Subscription: The $12/month Safety plan includes unlimited check-in messages, 10 custom texts/month, and SOS. The $25/month Recreation plan adds unlimited tracking points and weather forecasts. Pause the subscription during months you are not camping (you keep the device, just stop paying—reactivate next season).
ZOLEO pairs with your phone via Bluetooth and uses the Iridium network. Your phone is the keyboard—text through the ZOLEO app. The device itself provides the SOS button and check-in button (press to send a pre-set "I'm OK" message). The unique feature: ZOLEO gives you a dedicated SMS number. Friends and family text that number, and the message arrives at your phone via satellite—without them installing an app. This reduces the friction of staying in touch from "please install and configure Garmin Explore" to "text me at this number."
