The PUK (Personal Unblocking Key) code is usually an eight-digit unique number assigned to a SIM card and is available as a security feature for all SIM cards. Most mobile phones have a PIN (personal identification number) designed to prevent unauthorized usage of your phone and keep SIM details safe. When someone enters a wrong PIN code more than thrice, the SIM card might get blocked. For instances where this is a genuine mistake, the PUK code is the solution to reset the PIN and unblock your SIM card. In such situations, the PUK code is provided by the telecom service provider after the verification of the user.
