LTE and Satellite Connected Features

NOTICE

The LTE and satellite connected features, including SOS, require an active inReach® service plan, and are only available for the fēnix® 8 Pro watch.

On a fēnix 8 Pro watch with an active inReach service plan, you can stay connected while leaving your phone at home. By default, when your phone is within Bluetooth® range, your watch uses your phone's LTE connection. When your phone is not within range, your watch connects to the LTE network. If an LTE network is not available, some features are available through communication satellites.

Connecting to Communication Satellites

On a fēnix 8 Pro watch with an active inReach service plan, you can connect to a two-way communication satellite when you are outside of an LTE coverage area. Communication satellites travel in a geostationary orbit, and are much farther away than the GNSS satellites in low Earth orbit that are used for navigation. In order to connect to a communication satellite, you must be in an area of coverage and point the antenna on your watch directly at the satellite.

  1. While outside of an LTE coverage area, select an option:
    The watch prompts you to turn towards the satellite.
  2. Hold your arm up, and turn until you are facing the satellite with the highlighted region on the compass 1 covering the Satellite icon.

  3. Rotate your arm away from or towards your body until the Satellite icon is enclosed in the circle 2.

  4. Wait while the watch connects to the satellite and sends your communication data.

Sending a Test Message

WARNING

You should send a test message outdoors before using the watch on a trip to ensure your service plan is active.

  1. Select an option:
    • Hold Upper-left button, and select Messenger.

    • From the watch face, press Upper-right button, and select Messenger.

  2. Select New message.
  3. Send a message to [email protected].
    NOTE: Your watch should automatically receive a message from this address after activating your service plan.
  4. Wait while the watch sends a test message.

    When you receive a confirmation message, your watch is ready to use.

Sending a Check-In Message

Check-in messages are messages with predefined text and recipients.

TIP: You can customize check-in message recipients in the Garmin Messenger app. From the Device tab in the app, select Check-In > Edit Check-in Contacts.
  1. Select an option:
    • Hold Upper-left button, and select Messenger Check-in.

    • Hold Upper-left button, and select Messenger > Messenger check-in message.

    • From the watch face, press Upper-right button, and select Messenger > Messenger check-in message.

  2. Select a message.
  3. If you are outside of an LTE coverage area, connect to a communication satellite (Connecting to Communication Satellites).

Checking for Messages

Your watch continuously checks for new messages in Always On LTE mode (LTE and Satellite Settings). In Auto LTE mode, when you use an LTE feature, such as the Messenger or Messenger Calls app, your watch temporarily turns on LTE connectivity and checks for new messages.

When you are not connected to an LTE network, the watch does not automatically check for messages, but you can manually check for messages. During a manual check, your watch connects to the LTE or satellite network and receives messages waiting to be sent to your watch.

  1. Select an option:
    • Hold Upper-left button, and select Messenger > Check for messages.

    • From the watch face, press Upper-right button, and select Messenger > Check for messages.

  2. If you are outside of an LTE coverage area, connect to a communication satellite (Connecting to Communication Satellites).

LTE and Satellite Settings

From the watch face, hold Middle-left button, and select Watch Settings > Connectivity > LTE & Satellite.

Status

Enables LTE and communication satellite connectivity. You can enable one, both, or neither connectivity type.

LTE Mode
