I have upgraded to a Sim only contract and been told I will be sent a new Sim card. Do I need to change Sim cards or can I just keepusing the old Sim cardas the new contract details are showing already on my account?

Although we recommend activating the new one, if you prefer to use the old one still you’re absolutely free to do so.
What we would advise however is that you keep the new one somewhere safe just to err on the side of caution.
