Transfer to an already set-up iPhone

You can also transfer your phone number after setting up your new iPhone as follows:

① On your new iPhone, go to Settings > Mobile Service > Set up mobile data or Add eSIM.

② Select the cellular plan you want to transfer from another iPhone. If no list of numbers appears, tap “Transfer From Nearby iPhone”.

③ Follow the instructions on your old iPhone. Tap “Transfer” to confirm. If prompted for a confirmation code, enter the code shown on your new iPhone.

④ Wait until the cellular plan is activated on your new iPhone. The old SIM card will be automatically deactivated once the plan is active on the new device.

⑤ If a banner with the message “Finish Setting Up Your CHmobile Mobile Plan” appears on your new iPhone, tap it.
