Unable to delete old phone number after changing device and carrier

I changed my phone number and carrier today and I can’t delete the old phone number.

Then, your "new" carrier has not provisioned your phone correctly.


Contact them.

In most countries, in settings turn off imessage and Facetime.

Restart the phone.

Turn them both back on

Look in

settings, apps, messages, imessage

settings, apps, facetime.

By the way next time you change numbers turn off imessage and FaceTime and turn phone off to deregister the old number first.
