Calls are dropping or no network signal on your Samsung Galaxy Watch

If calls are dropping or your Galaxy Watch cannot connect to a network, this is often caused by a temporary issue rather than a problem with your Samsung watch.

Calls are dropping or no network signal on your Samsung Galaxy Watch

Before troubleshooting, consider when the issue happens:

  • Does it happen only in certain locations or at specific times? This is usually related to network coverage or the surrounding environment.
  • Or does it happen all the time, regardless of location?
    This may indicate a more persistent issue that requires further checks.

Before you start

Make sure your Galaxy Watch is updated to the latest software version.

  1. Open Settings, then tap Software update
  2. Tap Download and install.

If the issue happens occasionally or in specific situations

  1. Try again
    End the call and try again after a few moments.
  2. Change location or try later
    Move to a different location, especially if you are indoors or in a crowded area.
    You can also try again later, as network conditions may vary during the day.
