So both? You've managed to lock your SIM & you want to move your phone to O2?
You don't really need to unlock the SIM to move the no. to O2.
To unlock the phone, if the device had been on your contract for at least 6 months, even if that contract has now been cancelled, you can just apply using the Unlocking your device form and giving the mobile number that it originally came with.
