2 Introduction
Pairing Your Phone and Activating the Device
WARNING
Before you can use the inReach features of your device, including messaging, SOS, tracking, and inReach
Weather, you must have an active satellite subscription. Always test your device before you use it outdoors.
The inReach device works best when it is paired with the Garmin Messenger app. The app allows you to
compose and send messages using your phone, and to sync contacts and check-in messages with your device.
1 Turn on the inReach device.
2 Bring your compatible phone within 10m (33ft.) of your device.
3 From the app store on your phone, download the Garmin Messenger app, and follow the on-screen
instructions to complete the pairing process.
4 Follow the on-screen instructions to activate a subscription service plan.
After the devices are paired, they connect automatically when they are turned on and within Bluetooth
®
range.
Garmin Messenger App
WARNING
Before you can use certain inReach features of the Garmin Messenger app, including SOS, tracking, and inReach
Weather, you must have an active satellite subscription and a connected inReach device. Always test the app
before you use it outdoors.
With an inReach subscription and a connected inReach device, you can use the Garmin Messenger app for
tracking, SOS, inReach Weather, and managing your service plan. You can also use the app to message other
inReach device users, as well as friends and family. The app works over both the Iridium
®
satellite network
and the internet (using a wireless connection or cellular data on your phone). Messages sent using a wireless
connection or cellular data on your phone do not incur data charges or additional charges on your inReach
subscription. Messages received may incur charges if message delivery is attempted over both the Iridium
satellite network and the internet. Standard text messaging rates for your cellular data plan apply.
Without an inReach subscription, the app also provides a messaging experience for friends and family. Anyone
can download the app and connect their phone, allowing them to communicate with other app users over
the internet (no login is required). App users can also create group messaging threads with other SMS phone
numbers. New members added to the group message can download the app to see what others are saying.
You can download the Garmin Messenger app from the app store on your phone (garmin.com/messengerapp).
Iridium Satellite Network
Your device requires a clear view of the sky to transmit messages and track points over the Iridium satellite
network. Without a clear view of the sky, your device attempts to send the information until it acquires satellite
signals.
TIP: For the best connection with satellites, the top of the device should be oriented toward the sky.
Syncing inReach Data
After you make edits to your data, such as plan changes, contacts, or check-in messages, you must sync your
device using the Garmin Messenger app.
1 Open the Garmin Messenger app.
2 Wait while your data syncs.
TIP: You can check the connection status on the Device tab in the app.
