Sky mobile sim

[Soo]

I ordered a new sim as my SIM card is out of contract but it's added it to my account rather than replacing my current one? Can I replace my current one or does it have to be an add on? I don't want to be paying for two sims when I am going to be using one

Being 'out of contract' just means you can cancel it should you wish (and there's no offers applied)

Any new dataplan you activate you be in addition and will have a new phone number.

You cannot easily transfer numbers across SIMs.
