Change SIM registered name

[ZakariyaM]

 Currently my SIM is registered by my brother name. I do want to switch its registration into my name keeping the same SIM number. Besides that, I am willing to buy Iphone15 pro max in contract. What should I do to change the registered name into my name?

If it’s payg then as far as I’m aware you can contact customer service and change the details. If it’s a pay monthly sim then I think you’ll encounter issues and likely need to pass a credit check. Either way your brother will need to be the one to make contact as the number is apparently in his name not yours.Your best bet is either contact c/s or if you’re near go to a Three shop.
