fill default code which should 1234 and ok,and yes plz tell is it asking PIN no. or just security code for phone.if its PIN no. then don't try again and again because after 10 times you fill wrong PIN your SIM will ask about PUK code.
its 12345, I guess
His phone is not asking for PUK code.AFAIK the fone's askin PUK code right ?
call go to Nearest Dealer(ur sim cards)
