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:
• Off: you can call any number.
• On: you can only call phone numbers stored in Phone book. You must enter your
PIN2. The following options are available:
• Full length entries or wild cards can be entered in to the FDN list.
• A full length number with a specific contact name can be entered into the FDN list.
• Wildcard entries allow a range of numbers to dial with a single entry: ex. 555 – All
dialed numbers that begin with 555 are allowed. Numbers that do not match the
conditions in the FDN list are restricted.
Note: Entering an asterisk (*) is not required for wild card entries.
Note: Not all SIM cards have a PIN2. If your SIM card does not, this menu does not display.
