Testing inReach Service to Verify Active Subscription
If you have an active inReach® satellite communication subscription, it is recommended to test your service before taking your inReach handheld out for use.
A test can be run from either the website or on most inReach handhelds. Original inReach Explorer® and inReach SE® handheld models can only run the test from the Garmin Explore™ website. Each test requires you take your inReach handheld outside in a clear view of the sky and 5 free test messages are included each month.
IMPORTANT: If you have the Garmin Messenger™ app on a paired smartphone, make sure to power off your smartphone or enable airplane mode on the smartphone until the test is complete.
