Wandering if anyone knows how to unblock a sim card?

You request your puk code here : http://www.o2.co.uk/puk/landing/

It is kept in your account under account details, if you use one. Log into My O2 and you shall find otherwiser you have to do what was said before.

Bear in mind that if you have entered an incorrect PUK number 10 times then your only option would be a replacement sim card.
