If you've recently asked us to amend your price plan, the details shown below are your NEW details, which will take effect on your next bill date.
Your price plan:
3 Broadband Two - 18 Month
Which is my old 30GB plan. I'm somewhat concerned as it explicitly states these are the details of any new plans I have changed to.
I also received a new SIM with the new modem. Do I need to cancel my old plan and start using the new SIM? And how can I confirm my new 750GB plan will take effect during the next billing window?
