<P>PROBLEM TO BE SOLVED: To provide a mobile data transmission and reception terminal device which easily transmits and receives e-mails or the like for free without using a telephone line, and to provide a mobile communication system using the same. Ž<P>SOLUTION: A terminal uses a weak radio wave to successively automatically transmit and receive data of e-mails or the like with respect to a plurality of transmission and reception terminals. Another terminal existing in an area where radio communication with that terminal is possible receives the transmission data by communication units and stores the received data into temporary storage memories (RAM) and causes a liquid crystal display to display the received data stored in the RAMs. Thus, users who have received mails can read mails addressed to themselves.
