The number is registered to my Apple ID, but is not associated with my iPhone
I keep getting this message and what do I need to do?
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.
Then I have the option to "Remove from iMessage and FaceTime"
