  2. Turn on your new Apple Watch®.
  3. Open the Watch app on your phone.
  4. Follow the prompts to pair Apple watch with your phone.
  5. Follow the prompts to set up cellular service using NumberSync.

If your watch still doesn’t have wireless service, activate your watch now.

 

Android smartwatch

 

If you haven’t already, make sure you get a wireless plan for your Android® watch. Then, download your eSIM:

  1. Turn on your watch.
