Just a heads up, down load the Garmin connect app onto phone or Garmin express onto computer and check for updates for the Inreach. Should do this before each trip, and also send test message to those you keep in contact with. Had a little glitch with this on a Sheep hunt Oct.10-15, would have saved me a bit of grief once I got home. This was the only small issue( not getting a response to a message I sent, even though they sent a response), in the 2 years I've had one.
