What is a Personal Unblocking Key (PUK) Code?

A Personal Unblocking Key (PUK) code is a unique code assigned to a mobile phone’s SIM card. It is used to unblock a SIM card that has become locked due to multiple incorrect attempts to enter the SIM card’s Personal Identification Number (PIN).

When a SIM card is locked due to too many failed attempts to enter the PIN, it becomes unusable, and the phone will display a message asking for the PUK code. Entering the correct PUK code allows you to unlock the SIM card and reset the PIN to a new one.

It’s essential to keep your PUK code safe and not share it with anyone, as it can be used to gain access to your phone and its contents. If you can’t find your PUK code, you can contact your previous mobile carrier for assistance or a tech support specialist to obtain it. Usually, the tech support specialist will ask you to verify your identity and provide some information to confirm that you are the account holder before giving you the PUK code.

It’s important to note that if you enter the wrong PUK code too many times, your SIM card may become permanently blocked, and you will need to obtain a new SIM card.
