FDN Meaning and
Definition
-
FDN stands for Fixed Dialing Number. It is a term used in telecommunications and refers to a feature available on mobile devices that restricts outgoing calls to a predetermined list of phone numbers. FDN is typically used for security purposes, allowing the user to control and limit the numbers that can be dialed from their phone.
When FDN is enabled on a mobile device, the user can configure a list of authorized phone numbers, usually stored in the device's SIM card or memory. Only the numbers present in this list can be dialed from the phone, and any attempts to dial other numbers will be blocked.
FDN is commonly used in business or enterprise settings, where employers want to restrict phone usage to specific numbers, ensuring that employees make calls only to approved contacts. It can also be used for personal reasons by individuals who wish to limit outgoing calls, especially in cases where permissions need to be set for children or elderly family members.
The FDN feature offers an additional layer of control and security, helping prevent unauthorized or accidental calls, as well as reducing the risk of incurring excessive charges for international or premium number calls. It provides peace of mind to both businesses and individuals by allowing them to have greater control over their phone's calling capabilities.
