I have recently upgraded , through the app, from a monthly sim only deal to a 24m new phone & plan.
I wanted to retain the original number but I have been sent a new phone number & account number with the new phone.
I don’t want to be paying for both plans, just the new phone contract with the old phone number.
Do I need to cancel the old sim plan and get the number transferred? - If so how do I go about it since it is impossible to get hold of anybody human to talk to.
