PUK Codes
A PUK code is the unlock code for the SIM card. When
the SIM card is locked, you have to enter the correct
PUK code and then enter the new PIN code. The SIM
card can then be used normally.
• A PUK code may be supplied with a new card.
Contact your service provider for more information.
• A PUK code can only be entered 10 times in a row. If
you enter the wrong PUK code more than 10 times,
the SIM card will be locked indefinitely.
NOTE: If a PUK code is supplied with the new card,
remember to store it safely.
