Garmin inReach Messenger Plus Say it, show it, share it with the inReachA(R) Messenger Plus SOS satellite communicator. Keep in touch with friends and family beyond cell service, and exchange two-way text messages with an active subscription. Connect your compatible smartphone, and tell them you miss them or show them the view with voice recordings, photos, and group messaging on the Garmin Messenger(TM) app. Explore with peace of mind knowing you can trigger an interactive SOS message anytime with your GPS coordinates to Garmin Response, a 24/7-staffed coordination center for help in an emergency. And instead of relying on tower-based cellphone coverage, your messages are sent via the 100% global Iridium satellite network. Plus, the durable design withstands extreme temperatures, and the battery lasts for weeks. A subscription plan is required to send and receive satellite messages on this device.
