The PIN2 code comes with some SIM cards and is
required to access some functions, such as charging
unit counters, which must be supported by the SIM
card.
If you enter a wrong PIN or PIN2 code three times in a
row, that PIN or PIN2 code is disabled. You will be
prompted for the PUK code (for the PIN) or the PUK2
code (for the PIN2) and a new PIN or PIN2 code.

required when you want to change a disabled PIN2
code.
If you enter a wrong PUK code ten times in succession,
you cannot use the SIM card any more. Contact your
network operator for a new card.
