Could someone please advise me as my son has gone and blocked the sim on his philips 535.
He has phoned up O2 and got an unblocking code (8 digits), but when I go into the security settings to put the code in the only icon there is "keypad lock".
Does anybody have any suggestion, or is it got to be a new phone?
It is nothing to do with the phone. Put the sim card in a Nokia phone and if he hasn't exceeded the attempts at entering the PUK code the phone will ask for a PUK code, enter this. Then enter a new pin code and then confirm the pin. The sim should be unblocked. Now take the sim out and put back in the phillips phone and all should be okay.
