Deregister number that is no longer in service
I switched carriers after my iPhone broke. Then I bought a new iPhone under another carrier's plan. I need to deregister a phone number that is no longer in use from the previous carrier but in order to deregister it I need to receive a code from a phone number that doesn't exist anymore, and I cannot do that as I have a new phone number now. Please help!! I need to connect my new phone number to my Apple ID so I can receive messages and calls from my phone number and Apple ID on my iPhone and MacBook!
iPhone 11, iOS 15
