What to do if the error message "Unable to complete cellular number change" appears?
- Close the app and reopen it, log out of the current account and log in again.
- Check if too many eSIMs have been installed on the device (some devices limit the maximum number of installed eSIMs to 8). Delete unused eSIMs and try again.
- Confirm the package has not expired; if expired, repurchase.
- Contact customer service to verify the number status and assist with configuration completion.
