How do I switch between Pay monthly and Pay as you go?

I want to switch and keep my number

I’d like a new number

If you want a new number when you switch from Pay as you go to Pay monthly, all you need to do is choose the plan you want Then get rid of your old Pay as you go SIM.    

Before you switch, use up any credit you have on your Pay as you go SIM, because we can't transfer it to your Pay monthly account.

Moving from Pay monthly to Pay as you go? To switch and get a new number, just cancel your Pay monthly plan and order your free Pay as you go SIM When it arrives, pop it in your phone and top up to get started.
