Hi
PUK code is called as PERSONNAL UNBLOCKING KEY.
Your phone will ask for PUK code when you entered the PIN code wrongly several times depending upon the mobile make. The mobile asks for PUK code so that unauthorized persons do not use your mobile for wrong cause.
To get PUK code please contact your service provider through phone or go directly to their office. They will provide you the PUK code for your mobile. The PUK code for mobile phone.so that you can open your phone. When you planning to call your service provider you cannot use your mobile as it is fully locked. Please use some other mobile with same network to call your service provider.
While you get the PUK code ,the service provider customer care officer will ask for your personal details to check whether the mobile belongs to you only. If they are satisfied with your answers they will provide with the PUK code
DONOT enter the PUK code several times wrongly,It will block your sim card permanently.
This PUK code is FREE. You no need to pay any sum to get the PUK code

PUK stands for Personal Unblocking Key, and it is a unique identificative code to prevent theft, or unauthorized users from using your SIM.
Even if it comes with the phone, PUK code is associated to SIM card, not to the phone.
When you input wrong SIM card pin three times , the phone will ask the PUK code.
Usually PUK is printed on a sticker inside phone box.
If you have lost your PUK code you will need to call the company that provides you the phone service when you bought the phone (eg. Vodaphone, Orange, 3, Telecom etc.).
The only alternative is going to a phone shop, they will call the phone company , get PUK and unlock your SIM.

Some phones have also an unlock code, but this is not called PUK, if phone asks for PUK you need to call phone company.
There is no way to get PUK straight from the phone.
If phone is locked with Phone Lock Code go to a local phone shop, they will connect it to a computer and get the code.

you have entered the pin code wrong 3 times now you are required to enter a puk code to reset the pin code. 

The puk code is sim card spesific it comes with the sim card when you get it or you can get it by calling your phone service provider of the sim card to get the puk code. 


if you have entered the puk code wrong too many times you will make the sim card useless and you will have to contact your phone service provider for a new sim card, it will probably cost.
