The PUK full form stands for Personal Unblocking Key. It is a unique code that is used to unlock a blocked SIM card. When you enter an incorrect PIN number multiple times, your SIM card gets blocked and you will need a PUK code to unblock it.
The PUK code is provided by your mobile network operator and is usually printed on the SIM card packaging or can be obtained by contacting the customer support of your network provider. It is important to note that entering the wrong PUK code multiple times can permanently block your SIM card, so it is crucial to enter the correct code.
When you enter the PUK code correctly, your SIM card will be unblocked, and you will be able to use your phone again. It is important to keep your PUK code in a safe and easily accessible place, as you may need it in the future if your SIM card gets blocked again.
It is also worth mentioning that the PUK code is different from the PIN code. The PIN code is a security feature that is used to prevent unauthorized access to your SIM card. It is recommended to change your PIN code regularly to enhance the security of your SIM card.
