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.
