Abstract
A mobile radio-telephones having a plurality of number assignment modules ("NAM's") selects automatically one of the NAM's for use for communication. In a preferred embodiment, the mobile radio-telephone attempts to match system identification data in received control signals with system identification data stored in the NAM's, and, on encountering a match, will use the NAM containing the matched system identification for telephone communication.
