PUK Code
PIN UnlocK code / PIN Unlock Key
PUK is the code required to unlock a GSM SIM card that has disabled itself after an incorrect PIN code was entered 3-5 times in a row.
See: PIN
If an incorrect PUK code is entered a certain number of times (typically 5-10), the SIM card will permanently block (disable) itself.
You must contact the carrier (service provider) that issued the SIM card to obtain the PUK code. (We don't have it. Please don't ask.)
