Your nokia 6020 doesn't have problem. It's your sim card. If you still have your simcard packaging, the PUK code is written their inside it's brochure. Or you can also go to your mobile phone network and ask its PUK code. Or simply buy a new simcard with the same network company. Thank you

Hi

You can obtain the puk code by contacting your phone service provider.

If you have entered the puk code wrong too many times (tried to guess it) the sim card has disabled itself, and its useless, you will have to contact your phone service provider to obtain another sim card.

I've explained more about it here
