A Fixed Dialing Number (FDN) is a feature available on mobile phones that allows users to restrict outgoing calls to only certain numbers. It is a useful feature for parents who want to control who their children are calling, or for people who want to limit their phone bills by preventing accidental calls to premium rate numbers.
What is a Fixed Dialing Number?
A Fixed Dialing Number (FDN) is a feature available on some mobile phones that restricts outgoing calls to only certain numbers. It is a feature that can be enabled or disabled by the user. When the FDN feature is enabled, the user can set up a list of approved numbers that will be allowed to be called. If an outgoing call is attempted to any number not on the list, the call will be blocked.
Benefits of Using a Fixed Dialing Number
- Increased Security: With the FDN feature enabled, users can have peace of mind that their calls are being restricted to the numbers that they have specifically approved. This is especially beneficial for parents who want to control who their children are calling.
- Cost Control: By restricting outgoing calls to only certain numbers, users can prevent accidental calls to premium rate numbers and other expensive services. This can help to reduce phone bills and save money.
- Improved Privacy: With the FDN feature enabled, users can be sure that their calls are only going to approved numbers. This ensures that their conversations remain private and are not being shared with anyone else.
The Fixed Dialing Number feature is a useful tool for those who want to have more control over their phone usage. It is a great way to ensure that calls are only being made to approved numbers and that phone bills are kept to a minimum.
