PIN code and PIN2 code
The PIN (personal identification number) code (4—8 digits) protects your SIM
card against unauthorized use. The PIN code is usually supplied with the SIM
card.
Set the phone to request the PIN code each time the phone is switched on.
See Security settings.
The PIN2 code may be supplied with the SIM card and is required to access
some functions, such as charging unit counters.
If you key in an incorrect PIN code three times in succession, the phone may
display SIM blocked and ask you to enter the PUK code. Contact your service
provider to obtain the PUK code.
PUK and PUK2 codes
The PUK (personal unblocking key) code (8 digits) is required to change a
blocked PIN code. The PUK2 code is required to change a blocked PIN2 code.
If the codes are not supplied with the SIM card, contact your local service
provider for the codes.
Restriction password
The restriction password (4 digits) is needed when using the Call restriction
service, see
Security settings. You can obtain the password from your service
provider.
