How to fix Apple ID number registration error?
Recently traveled to Europe and had to use a pay as you go sim card, after returning home and replacing my sim card I get this message:
"This number is registered to your Apple ID, but is not associated with this phone. You can keep using the number for iMessage and FaceTime until it expires."
I turned off iMestsage and Facetime, restarted to no avail.
It says I have 18 days left
