ABSTRACT:
A cellular radio telephone (5) has two (or more) telephone numbers (TN1 . . . TNN), specifically for example an office telephone number and a private telephone number. In one mode of operation both numbers are operable concurrently. However, in a second mode one of the numbers may be disabled by the user, e.g. using a menu selection facility on a visual display (55). In the first mode, the telephone number of an incoming call is shown on the display (55) so that the user can know which number the call is intended for before answering it. Preferably one of the telephone numbers may be selectively enabled for outgoing calls, again by menu selection. As a consequence all of the other telephone numbers may be automatically disabled for outgoing calls in both modes of operation.
