Can't use FaceTime or iMessage 0n iPad or MacBook

[EdwardF_2720446]

I joined SMARTY last month and ported my number from my previous network provider (THREE). All seemed to go well: this number appears on my SMARTY dashboard and calls/messages are coming in, plus this is the number that shows for me when I contact others. 

However, the original/temporary number is still associated with my Apple ID on my iPhone 15pro (and on appleid.apple.com) not the ported number.

Therefore, I cannot use FaceTime or Messages on my iPad or MacBook because the number is incorrect. 

How do I resolve this, please?

@EdwardF_2720446 Have you tried signing out of your Apple ID on those other devices as well before signing back in?

I'll try that now
