PIN2 code
The PIN2 code, supplied with some SIM cards, is required to access some
functions, such as charging unit counters. These functions are only available if
supported by your SIM card.
If you enter an incorrect PIN2 code three times in succession, follow the same
instructions as for the PIN code but use the PUK2 code instead.
