Hi,
I had an ID sim card back in the summer but cancelled it. I now have a better deal with but because you can only register one sim/phone number per account and the old one seems to be still registered to my account I can’t register my new sim and look at my account.
It there a way to either completly remove my existing account so I can re-register or remove my old mobile number and add the new one? Whichever is easier.
