| eSIM number change or transfer |
To change the eSIM number for your watch or transfer the number to a new watch, you'll need to first deregister from the activated eSIM service, reset the eSIM configurations, and then reactivate the service.
- Deregister from the activated eSIM number by contacting your carrier. Otherwise, fees will be deducted continuously and the number cannot be reactivated.
- Re-activate the eSIM service for a new phone number or a new watch.
Contact your current carrier to check whether porting out your number to another carrier will affect the eSIM service.
Thanks for your feedback.
