Phone not updating to new number

[BP30]

I ordered a new sim and gave my PAC code when ordering to keep the same number.

My o2 account is saying the correct number but my iPhone is showing the wrong number - what can I do?

Settings >> Phone >> My number

Change it, save the change, and reboot

Did you do a sim swap? SIM Swap: a mini guide (incl eSim) - O2 Community

Thanks! I'v tried doing that but it won't save, it just immediately reverts back to the other number.

Try these options

Try restarting your phone (Restart your iPhone, iPad, or iPod touch - Apple Support), and if that doesn't help try settings/general/reset - reset network settings. You will have to re-enter Wi-Fi passwords, but won't lose any data.

If you are having trouble with saving your phone number when messaging or facetimeing, go to Settings >Messages>Send & Receive. In the "You can be reaches" section, there should be a check mark next to your phone number.
