Bluetooth calls and standalone eSIM calls on your HUAWEI smart watch

Your watch supports Bluetooth calls and standalone eSIM calls in different situations.

The support for call forwarding by the eSIM One Number service varies by region. For details, consult with the customer service of your local carrier.

Syncing/Deleting contacts

Syncing contacts:

You can't add contacts on your watch. When the watch is connected to your phone via Bluetooth, your watch will automatically sync contacts from your phone.
 
  • If the contacts are not automatically synced, open the app list on your watch, and go to Contacts > Sync contacts > Sync.
  • If you do not want to sync contacts, open the Huawei Health app, access the device details screen, go to Device settings > App management > Contacts, and disable Sync data to watch.

    This option is not available in the HUAWEI Health app on iPhones. iOS 18 supports contact authorisation. You can go to Settings > App > HUAWEI Health > Contacts, and sync contacts as required.

Deleting contacts:

For the contacts synced from your phone, you can delete them on the watch as follows:

  1. In the app list on your watch, go to Settings > Apps > Apps > System processes.
  2. Go to Contacts Storage > Storage > Clear data. Then, there will be no contacts on your watch. You can manually sync contacts from the Contacts app on your watch.

Answering/Ending a call on your watch

 
  • To use the eSIM service on your watch, you'll need to keep wearing your watch and disable Auto-disable network by going to Settings > Battery, swiping up on the screen, and going to Power saving > Auto-disable network.
  • When you use the eSIM service on your watch, features such as harassment blocking and blocklist are not supported. When the eSIM service is not used on your watch, the blocking settings on the phone will be automatically synced to your watch.

Answering a call: When you receive an incoming call, your watch will notify you and display the caller information. Tap to answer the call.

Ending a call: Tap to end the call.
