Hi I have the above mobi but can't use it @the moment as I was swopping networks it has unblock network sim. I've done service checking & think it's hardlocked so doubt if code will work if ee ever come back. I only have mobile as contact & very frustrating at this time.
If you've entered the wrong unlock code multiple times you can't unlock it, contact your Local support they might be able to reset the count so you can try a new code, also, Sony does not provide this codes.
