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
Thank You.
