How to Unlock SIM Card without PUK Number

PUK which stands for Personal Unblocking Key is an advanced level of security for your SIM card. It is an 8-digit code that is unique to your SIM card inside your phone and not to the phone itself. PUK is used to reset your personal identification number (PIN) in case you no longer remember it.
