Upgraded to iPhone 12 Pro swapped over to new phone and sim. All working. Following day cannot make or receive calls.

You'll need to call customer service.
Numbers here Guide: Coronavirus Community Help and Support 
When it comes to the reason you are calling stay silent for 15 seconds and you will be taken to the keypad options.
Press 2 for Everything Else
Press 5 for More Options
Press 7 for Anything Else which will put you though to someone.
Say "Upgrade", "Lost/Stolen" or "Fraud" if you have to, to get put through to someone.

I'm on phone with them via Skype at the moment, listening to the queue music

Glad you got your issue resolved. Did they happen to say what the issue was as I’m still having the same issue?
