A ringing tone data delivery system and a method used this system, in which at least a part of communication charge is not paid by a user of a cellular phone at the time when the cellular phone downloads ringing tone data from the outside, are provided. When a cellular phone sets a ringing tone, the cellular phone accesses to a database via a base station and a control station in a telecommunication network, and obtains ringing tone data. The database mainly stores the ringing tone data, and the ringing tone data are stored in the database in two types, that is, one is "only ringing tone data", and the other is "ringing tone data+advertisement data". The cellular phone downloads the ringing tone data from the database via the control station and the base station in the telecommunication network, and stores the ringing tone data in a memory through an antenna, a radio section, and a controller provided in the cellular phone. At the case that ringing tone data being "ringing tone data+advertisement data" are downloaded, the advertisement data are displayed on a display and/or outputted from a speaker in the cellular phone at the time while the cellular phone is downloading the ringing tone data or after the cellular phone finished downloading the ringing tone data. In this case, at least a part of communication charge at the time of downloading is paid by the side who sponsored the advertisement data.
