FDN Mode
FDN (Fixed Dial Number) mode, if supported by your SIM
card, allows you to restrict your outgoing calls to a limited
set of phone numbers.
The following options are available:
Disable: you can phone any number.
Enable: you can only call phone numbers stored in
Phonebook. You must enter your PIN2.
Note: Not all SIM cards have a PIN2. If your SIM card does
not, this menu does not display.
Change PIN2
The Change PIN2 feature allows you to change your current
PIN2 to a new one. You must enter the current PIN2 before
you can specify a new one.
Once you have entered a new PIN2, you are asked to
confirm it by entering it again.
Note: Not all SIM cards have a PIN2. If your SIM card does
not, this menu does not display.
