Fixed Dialling And Restricted Calls

For a company or an organization, it can be useful to restrict phone calls. Fixed Dialling allows you to preset a number of digits, for example area codes. This restricts the user to making calls only to numbers which use the preset digits as leading digits. Fixed Dialling makes use of the PIN2, and it requires fixed dial fields on the SIM Card. Check with your Operator about this feature.

Restricted calls allows you to block outgoing or incoming calls in certain situations, for exam- ple international calls.
