Abstract
Abstract A radio telephone and pager system includes a radio telephone handset and a pager that detachably mounts to the handset. The pager employs a transceiver that provides both paging service, such as a messaging service, and radio telephone service, such as cellular service, when the pager is mounted. Also, the transceiver provides the pager service when the pager is detached. The invention achieves a reduction in a number of components while enabling subscribers to use a single telephone system to provide both a radio telephone and a stand-along pager.
