Fixed Dialing Numbers in Android

Fixed Dialing Number which is commonly abbreviated as FDN in  mobile devices is a service which allows owners to set up restrictions to numbers they only want to call (out going calls). When the FDN service is activated, all outgoing calls are limited to only those numbers in the FDN list there by cutting out those which aren’t added.
