Fixed Dialing Numbers
Fixed Dialing Number (FDN) is a service mode of SIM, where outgoing
calls are restricted to a set of phone numbers. These numbers are added
to the FDN list. The most common practical application of FDN is for
parents to restrict the phone numbers to which their children can dial.
For security reasons, you’ll be prompted to enable FDN by entering SIM
PIN2 which is usually acquired from your service provider or SIM maker.

TTY and converts outgoing text from the TTY machine to a spoken voice
for the person on the other end of the conversation.
