IPhone 12

Can anyone help... I've set up my new iPhone 12 but for some reason it won't allow me to make or receive any calls 🤷‍♀️
I've tried troubleshooting but it hasn't made any difference.

Re: IPhone 12

Is this a new contract or upgrade?

If it's an upgrade and you have put a new sim in, you will have to do a sim swap by texting SWAP to 20220 from your old sim. Or just use your old sim.

Re: IPhone 12


The only reason to do a sim swap is if you are in a 5g area, otherwise, just use your old sim which will work normally on 4g.

Your new contract is already updated on your old sim and old contract has been closed down.
