PUK Code
A PUK (Personal Unlocking Key) code is required to unlock your SIM. When the
SIM is locked you have to enter the correct PUK code and then enter the new
PIN. The SIM 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 will be locked indefinitely.
