PUK is an acronym that stands for "Personal Unblocking Key." It is a security feature primarily used in mobile phones to protect the SIM card and prevent unauthorized access or use. The PUK code is provided by the network service provider and is unique to each SIM card.
When a user enters an incorrect PIN (Personal Identification Number) multiple times in succession, the SIM card becomes blocked. This is where the PUK code becomes necessary. The PUK code serves as a master unlock code for the SIM card, allowing the user to unblock it.
Upon entering the PUK code correctly, the user is prompted to set a new PIN. This provides an added layer of security and ensures that only authorized individuals can access the mobile device and use the SIM card.
It is essential to keep the PUK code in a safe place, as it is required in cases of accidental SIM card locking. Losing the PUK code may necessitate obtaining a new SIM card from the network service provider.
In summary, the PUK (Personal Unblocking Key) is a unique code provided by the mobile network service provider to unlock a blocked SIM card. It allows the user to gain access to the mobile device and set a new PIN.
