Contract phone and SIM card?

I have a contract with O2, I lost my SIM card and was wondering how I would go about cancelling the SIM card so that nobody can run up a bill under my name.



How would I go about changing my contract to a new SIM card?

Also how and where would I get a SIM card



Thank you.Contract phone and SIM card?
Just phone them up and tell them and they should send you out a replacement sim for free and cancel the old one. They did this for me.Contract phone and SIM card?
As i said on the other one.



Register a new sim card to the same number and the old sim card will no longer work. ;)Contract phone and SIM card?
There should be a number to call for this kind of emergency in your billing statements that you can dial from landlines. If you haven't got those, just go to your local O2 shop as soon as possible so you can sort this out.

Tell them you want to get a new sim card as well (with the same number).
