PIN Lock prevents unauthorized use of the SIM card.
PIN is required to enable PIN Lock. Caution: If you enter the PIN incorrectly 3 times, the SIM card will lock, and you will need a PIN Unlock Key (PUK) to unlock your SIM card.
PUK is required to unlock SIM cards that have become locked following 3 successive incorrect PIN entries. Caution: If you enter the PUK incorrectly 10 times, the SIM card will be permanently locked and no longer operable.
If the SIM card has been locked because an incorrect PIN was entered 3 times, you can enter a new PIN with the PUK.
