PAC Code- Temporary Number still showing on iPhone

[DutchTurtle34]

I bought a sim only deal with O2, and arranged for a PAC code to bring my number from Vodafone to O2.

I went through the PAC process, and calls/texts to my number (iPhone 12 Pro) now come through on the O2 sim. However, under Settings-Phone- My Number, my temporary number is still shown, as it is under my iMessages options. 

How do I get this number changed to the correct, ported number?

Thanks

You need to get a blank sim from an O2 store and then transfer your number on to it

Have you tried to edit the number?

Press "done" when you have then reboot the phone.

Ok, thanks. I will pop down there tomorrow and see if that fixes it

Hey,

Yep, I tried that, but it just resets to the temporary number when I click Save

Right. I've taken it to the local O2 store, and they suggested I log in and out of iCloud, but it made no change. I came home and googled, and then went to reset network settings. That seems to have done it.
