if you have entered the wrong code more than 5 times the phone will lock and you can't reset it, the only to do so is to contact your Local support, but since your phone was purchased in the UK you will have to send it to the UK
@ahmedeberhim1995 What code are you talking about to be more specific? The SIM PIN can be entered incorrectly 3 times and after that you are required the PUK code.
If u forget your PIN code and doesnt know PUK code, u can always contact your mobile operetor and ask for PUK code. Or u ofcours can always change your SIM card for free.. Dont worry.. it happens..
