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 call any number.
• Enable: you can only call phone numbers stored in Phonebook. You must enter your
PIN2. You can obtain your PIN2 from T-Mobile’s customer service department.
Change PIN2
The Change PIN2 feature allows you to change your current PIN2 to a new one. You
must first enter the current PIN2 (obtained from T-Mobile) 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.
