What is FDN Contact in Samsung Keypad Phone b110e e1200 b310e b313e e1200y

FDN (Fixed Dialling Number) or FDM (Fixed Dialling Mode) is a service mode of GSM phone's Subscriber Identity Module (SIM) card feature that allows the phone to be "locked" so that it can only dial certain numbers, or numbers with certain prefixes. Incoming calls are not affected by FDN service.
