Fixed dialling numbers (FDN)

Fixed dialling is a feature that restricts outgoing calls to 'fixed' numbers or 'prefixes'
contained in SIMs that support this feature. When turned on, dialling numbers not
in the FDN list will not be allowed. The maximum number of FDN numbers that can
be stored is dependent upon the capacity of the SIM. Call diverting and sending
SMS messages to numbers not in the FDN list will be prevented. Turning on or en-
tering numbers into the FDN list is PIN 2 protected.
