I recently purchased a phone number from my mobile service provider. However, I discovered that the previous owner of this number had linked it to their Apple ID / iCloud account.
I am now the legitimate owner of this phone number, but I cannot add it to my own Apple ID because it is still associated with the previous owner's account.
I would appreciate your assistance in removing this phone number from the previous owner's Apple ID so I can use it with my own account.
I can provide proof of ownership of the phone number from my mobile service provider if needed.
