2 PUK and PUK2 codes (8 digits)
PUK stands for Personal Unblocking Key. If you have entered your PIN code incorrectly 3 times, your SIM card will be blocked and you will be unable to make and receive calls/text. The PUK code is required to change a blocked PIN, and the PUK2 code is required to change a blocked PIN2 code. If the codes are not supplied with the SIM card, contact your local service provider for the codes. If the PUK code is entered 10 times incorrectly, the card is permanently disabled and the SIM card has to be changed.
