Update Your FaceTime Number?

Hi, both my mum and her friend have a problem with FaceTime.

They upgraded to iPhones and had temporary numbers while their PAC code was used to change that new number back to their old one that they had had on their old phone.

They can both be texted and called in the traditional manner on their original number, but their iMessage and FaceTime has stuck with their temporary number that they only had for 36 hours and now that the main number has been activated they can't be reached on FaceTime on their main number, only on their temporary number that they no longer have.

How can they transfer their FaceTime to their main number that they had before and have now, from the temporary one that they had just very briefly after getting the new handset.

Thanks.

Added (1). John: Yes but the contact telephone is greyed out, and can't be edited. Facetime is stuck with the temporary number and didn't transfer along with the main number that calls and texts go to.

Did you try on the phone going in to Settings > Facetime

Follow these instructions. Have them both log out of iMessage and then back in but change the number to the correct one. Best luck.
