If you reported your phone/sim lost O2 would have put a block on your account, so CS will have to lift the block before you can do anything.
Contact via one of the methods here and they will activate the account for you

I have no affiliation whatsoever with O2 or any subsidiary companies. Comments posted are entirely of my own opinion. This is not Customer Service so we are unable to help with account specific issues.
Please select the post that helped you best and mark as the solution. This helps other members in resolving their issues faster. Thank you.
