A system user can use this screen to whitelist/blacklist outgoing SMS numbers. The whitelist is the exception to the blacklist.

NB .* (dot star) can be used as a wild card, for example if the device is not allowed to send outgoing SMS from 01924555678, the number could be typed in the blacklist in its entirely or the system user could type .*678 or 01924.*. Both patterns would block the original number.
