PIN code
The PIN (Personal Identification Number) code protects your SIM card against unauthorised use. The 
PIN code is usually supplied with the SIM card. 
When the PIN code request is enabled, the code is requested each time the phone is switched on (see 
PIN code request on page 79).
If you enter an incorrect PIN code three times in succession, the SIM card is blocked. Key in the PUK 
code and press 
 (
OK
). Key in a new PIN code and press 
 (
OK
). Key in the new code again and 
press  
(
OK
).
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.
PUK code
The PUK (Personal Unblocking Key) code is required to change a blocked PIN code. The PUK code may 
be supplied with the SIM card. If not, contact your local service provider for the code. If you lose the 
code, contact your service provider.
PUK2 code
The PUK2 code, supplied with some SIM cards, is required to change a blocked PIN2 code. If you lose 
the code, contact your service provider.
