You must follow the procedure here for lost and stolen
Only then will you be issued with a new sim when O2 have barred your old one
Best of luck

Thanks but I don't loose my phone it's only a sim card.
I am well aware of that @Kate2. The process is the same however, whether you lose your sim or your phone. It can still be picked up and used by other people. You would be liable for any charges if the sim was used fraudulently.
So please follow the advice given.
