All three Garmin inReach devices use the Iridium satellite network. The differences are in device design, weight, and how much you depend on your phone. For most AT hikers: inReach Mini 2 is the right default. The Messenger is right only if phone battery discipline is genuinely not a concern.

Detailed breakdown
Best Overall: Garmin inReach Mini 2 — $350, 9.4/10
The definitive portable Iridium communicator. Standalone screen and keyboard mean it works when your phone battery is dead. 14-day battery in tracking mode. All inReach subscription plans compatible. The $350 price point is justified by the standalone capability that matters most in actual emergency scenarios.
Best Ultralight: Garmin inReach Messenger — $300, 9.0/10
1.5oz versus the Mini 2's 3.5oz — a genuine 2oz savings on a device you carry every mile. The cost: phone required for all messaging; SOS button works standalone but you cannot compose or read messages. The right device for hikers who always carry a power bank and have never had a phone battery issue on trail.
Should you buy a used Mini 1?
The original inReach Mini is discontinued but available used for $200-280. It uses the same Iridium network and the same subscription plans as the Mini 2. The differences: older firmware, slightly less refined UI, and shorter battery life (90 hours messaging mode vs the Mini 2's improved battery). Reasonable value for budget buyers who can find a clean used unit.
Bottom line: Garmin inReach Mini 2 for most hikers who want standalone satellite communication. inReach Messenger for ultralight hikers with disciplined phone battery habits. Used Mini 1 for budget buyers.
