A first messaging system (112, 116) schedules (502) a first store-and-forward message (406, 408) for transmission to a subscriber unit (122) on a first channel (410) and enters (504) a second store-and-forward message (404) into a second messaging system (113, 116), the second message intended for the subscriber unit and including a scheduling instruction for receiving the first message. The second messaging system communicates the second message to the subscriber unit on a second channel (412), and the subscriber unit tunes (620) to the first channel, in accordance with the scheduling instruction, after receiving the second message. The first messaging system then transmits (506) the first message on the first channel as scheduled, and the subscriber unit receives the first message on the first channel.
