PIN2
The PIN2 (4 to 8 digits), supplied with some SIM cards, is
required to access specific functions, such as setting the
maximum cost of a call. These functions are available if
supported by your SIM card.
If you enter an incorrect PIN2 three times in succession,
the code is disabled and you cannot access the functions
until you re-enable it by entering the PUK2.
To change the PIN2, see “Change PIN2” on page 105
(
Menu 6.6.7 ).
PUK2
The 8-digit PUK2 (PIN Unblocking Key 2), supplied with
some SIM cards, is required to change a disabled PIN2. If
you lose the code, contact your service provider.
To re-enable your PIN2:
1. Enter the PUK2 and press the OK soft key.
2. Enter a new PIN2 of your choice and press the OK soft
key.
3. When the Confirm PIN2 message displays, enter the
same code again and press the OK soft key.
If you enter an incorrect PUK2 ten times in succession,
you will not be able to access the functions requiring the
PIN2. Contact your service provider for a new card.
