I had the same problem so I went into Menu-Settings-Network Services-Band Selection. It should then give you the option to select two different types of GSM Bands or Quad Band. I found that Quad Band works for me, but the GSM 850/1900 worked as well. Hope this helps!

The PUK code is not related to the handset.
It is rather associated with your SIM card.
When you enable the PIN in your SIM card, every time you switch on your phone, you will be asked for your pin. At given number of tries provided by your mobile operator, that you have provided the wrong PIN (usually operators set it at 3 tries), then you came to the stage called PUK-blocked.

To unlock, you would need the PUK code of the SIM card. The PUK code is usually an 8-digit code. This PUK code should have been provided to you when you purchased your SIM card. Some has the PIN-PUK code printed in the card body of the SIM card, while some attach it as a separate print out. Should your operator failed to provide this PIN-PUK code to you, perhaps, you would have to get it from your operator. Try calling their customer service. Just like the PIN, the operator as well could say how much tries do you have to successfully unblock the PUK of your SIM . The common number of tries set by the operators is 10 tries.

you can do this easily by phoning up your service provider eg o2 or vodafone. They will be able to give you the PUK code you need to unblock your phone.
