My phone model is nokia 5800d-1 it's locked now and I need a puke code to unlock it how can I find the puke code?

Hello
Finding a PUK (Personal Unblocking Key) number is not tough job. To find a PUK code all you have to do is call up on the customer care number and ask them to help you with the issue. Before they provide you the PUK code, they will ask you several questions. You need to give them the appropriate information. Customer care of your service provider are the only source from which can give you the PUK code.
At the time when you enter a wrong pin number three times. The phone asks you for a PUK number. The PUK code is generally eight digit number This PUK number is an unlocking code which helps you to unlock the phone and use it. If you enter a wrong PUK number 10 times than you simcard gets rejected. Then you will have to but a new simcard. It might happen that your phone might ask you for PUK2 after you enter your PUK number.
Hope it helps, if so do rate the solution

Sir please call to the related simcard customer care and say the last 6-digit number which is present before the simcard. then they will give the pukcode number to unlock the cellphone.........

The puk code is on your sim you will need to get it from your service provider,another sim may work in it without asking you for a puk code.
