Phone number registered to Apple ID but not this device. Number Expiring
I recently switched cell phone providers and everything was fine until recently when I kept getting an alert about my iMessage and FaceTime Number. In iMessage under registered numbers is my phone number. It has message saying "This number is registered to you Apple ID, but is not associated with this phone. You can keep using the number for iMessage and FaceTime until it expires." I have an option to remove that number from iMessage and FaceTime but I don't want to do that as this is my number.
Does anyone know how to fix this? This is my actual phone number and the only Iphone I own. I have tried to reset my device and switch iMessage and FaceTime on and off but no luck. Any help would be greatly appreciated.
iPhone X, iOS 14
