Abstract
Abstract A radiotelephone (303) comprises a plurality of subscriber identities (306-308) operative in a radiotelephone system (300) at the same time. The radiotelephone network (301) processes incoming and outgoing calls for the radiotelephone (303) using any one of the subscriber identities (306-308). A standard telephone interface (401) optionally provides communications between the radiotelephone (303) and one or more standard telephone sets (413-415) using any one of the subscriber identities (306-308). A method for operating the radiotelephone (303) is also disclosed.
