Using the PIN(4 to 8 digits)
The PIN (Personal Identification Number) protects your SIM against
unauthorised use. If you enable the PIN, every time the phone is turned on
you will be prompted to enter the PIN.
The PIN2 controls security for the
Fixed Dial and Call Charge metering. If
either PIN/PIN2 is entered incorrectly 3 times the phone will be locked and
then you will need to enter the PUK/PUK2 code. Contact your service
provider for the PUK/PUK2 code.
