A Personal Unlocking Key (PUK) code is a security feature on mobile devices that protects your SIM card data. If you enter your PIN code incorrectly multiple times, your device locks to prevent unauthorized access, requiring the PUK code to unlock it. You can usually find your PUK code on the original packaging of your SIM card or by logging into your account on your mobile carrier's website. Remember, entering the wrong PUK code too many times can permanently disable your SIM card.
