The delivered trial-listening music data is actually reproduced by the portable telephone; however, the number of reproduction times is limited, and the trial-listening music data is erased from a memory (RAM63) of the portable telephone after the trial-listening music data is reproduced for the predetermined number of reproduction times. Thus, a system is provided in which the user of the portable telephone can obtain the trial-listening music data of an incoming call melody without being charged for the fee, and can actually reproduce the trial-listening music data with the use of the user s portable telephone.
