Stop messing with it immediately. Only your service provider canprovide you with your PUK. It is not on your box and it is not onthe card that the SIM card was punched out of. The PUK is unique toeach SIM card so nobody on here can give you one (well, I guessthey can but it will not work) and if you put in an incorrect code10 times you will 'fry' the SIM card and will have to purchase anew one for around $25.00-$30.00. Call your service provider andexplain that your phone is asking for the PUK and they will give itto you and will walk you through putting it in and getting yourphone working again. I do know that AT&T also allows you to getyour PUK on their website but I do not know if others do that ornot.
