The PUK code (from English PIN Unlock Key, which could be translated as “PIN code unlocking key”) is a unique code, generally made up of 8 digits and associated with the SIM card of your mobile phone. When you generate the lock code on your SIM card and enter the lock code three times incorrectly, your phone will be blocked, and you will need the PUK code to access it again. Fortunately, this code is not hard to find.

Otherwise, the PUK code is only needed if you have entered a PIN code incorrectly and repeatedly.
