Abstract

A method and apparatus is for use in a radio communication system (100) for delivering a message from a system controller (102) to a selective call device. In the system controller (102) the method includes the steps of generating a first message intended for the selective call device (106), changing a delivery state of the first message to undelivered after the first message has been transmitted at least once from the system controller (102), and storing the first message in the system controller (102) when the delivery state is changed to undelivered. In the selective call device the method includes the steps of determining that the first message is stored in the system controller (102) and presenting user with information which indicates that an undeliverable message is being stored by the system controller (102) in response to determining that the first message (102) is stored in the system controller (102).
