You need to get the PUK code to unlock the sim card. The phone itself is OK; it's just the sim card that is locked. Alternatively, just put in anew sim card.

Hi
You can get the status of your handset from here:

but generally speaking if you need a PUK code, then this is usually only available from your Service Provider as it is linked to the SIM card as explained here:

Hope this is helpful, if so would you please register that with Fixya
Cheers
