Five things kill more people in the United States than anything else: heart disease, cancer, lung disease such as emphysema and chronic bronchitis, stroke and unintentional injuries such as those on roads or caused by medication overdoses.
PUK, which is sometimes called the PUK Code, stands for Pin Unlock Code.. It is occasionally called PUC, which is the same as PUK.. This special code is needed to unlock the cell phone if the wrong four-digit pin number has been entered three times in a row or if the SIM Card has been reported stolen.
If you're being asked to enter a PUK, you will need to contact your network operator to get your SIM card unlocked. This is for security reasons. Note that only your mobile phone network operator can legally provide you with a PUK code to unlock your SIM card.
