Meet the Garmin inReach Messenger: a handheld satellite communicator that gives you two-way text messaging in areas with no cell coverage. It supports group messaging with the Garmin Messenger smartphone app. You can also share your GPS location with others or trigger a SOS to the Garmin IERCC monitoring and coordination center when you need help.
The Garmin Messenger app lets you send messages to your loved ones via satellite or cellular networks. The inReach Messenger also brings you detailed weather updates. The rechargeable battery lasts up to 28 days in 10-minute tracking mode.
