Hello,

If your phone comes up with a display requesting for the PUK code, then it means your sim card is already locked and you need to type your unblocking code to get it opened.

The PUK means personal unblocking key. It is found inside the sim pack on the sim carrier where you broke out your sim card from. There are some numbers on it, Your mobile number, your pin code your PUK code which mostly used to be 8 digits and your bar code at the bottom of the sim carrier.

Enter the 8 digit code that is on the sim card carrier, that is your PUK code, then you enter a new password, then it will prompt you to re-enter it, then your sim will be unblocked. Be sure to enter a code that you will find easy to remember, if not the sim will be blocked again and you will be requiring the PUK code to unblock it.

If you do not have the Sim carrier, then you have to contact the service providers customer care so they will give it to you.

Take care and good luck
