Abstract
The present invention encompasses a pager and radiotelephone apparatus (100) having a radio pager section (102) and a cellular radiotelephone section (104) into one unit. The apparatus (100) may automatically receive a plurality of pages while the cellular radiotelephone section (104) is on, communicating a cellular telephone call, or off and unattended. The received pages are stored in the pager section (102) until the apparatus user acknowledges their receipt by a keystroke. The pages are then transferred to the radiotelephone section (104) and stored in non-volatile memory for later use.
