Hi,

Puk/PIN code is a secutity code that protects your SIM card, it is unique eight digit code specific to your SIM card. This code is required when the PIN number to unlock your mobile phone is entered incorrectly 3 times. You are then given 10 attempts to enter your PUK code. If an incorrect PUK code is entered after the 10th attempt, you will block your SIM card permanently and will require a new SIM card from your mobile phone provider.
PUK codes can be obtained through the following ways -
The PUK code is in your SIM card documentation Starter Pack.PUK stands for Personal Unblocking Key.


You can contact to your mobile phone provider, along with documentation or you total identification, and soon after they could give the PUK code.

Hope this helps.
