Wrong number on iMessage following sim swap

[LegendKillerUK]

Hi,

I changed from pay as you go with Three UK to a monthly contract with Three UK.

To facilitate this, you get a new SIM with a new number, you then fill out a form on their site to bring your old number from the pay as you go SIM over.

Both my iPad and MacBook asked if I wanted to add this new number to iMessage/FaceTime - I chose no both times.

I also selected to maintain my old number when the Settings app wanted me to update my trusted phone number.

Regardless, iMessage/FaceTime are now using the new number and I can't see how to get the previous one back.

Anyone any tips?

Thanks in advance.

Has the old number been ported over, or, still waiting on it to be taken care of by the telco? Wild stab, guessing that you will need to sign-out of iCloud/Apple ID on the phone, then sign back in, once the old number is active again. And that point, remove the new "temporary" number from "can be reached at", "start conversations from".
