Abstract PURPOSE: A method of giving multi text message and calling services and a system thereof are provided to directly manage a memory in a processor, without considering a memory map, and not to simultaneously generate text message and calling services, thereby simplifying a circuit and easily performing a programming process. CONSTITUTION: A system inserts an identifier into data(202). The data are transmitted to a UART(Universal Asynchronous Receive and Transmit) unit. A processor receives the data. An identifier of the processor identifies whether the data are text data or calling data(204,206). If the data are the text data, the identifier bypasses the text data to a wireless modem, and performs a text message service(208). If the data are the calling data, the identifier stores a voice signal in an RAM. A PCM interface converts the voice signal into a PCM voice signal, and delivers the PCM voice signal to the wireless modem to perform a calling service(210).
