A method of sending a data set, in particular a directory data set, to the portable terminal of a user of a cellular radiotelephone network, and in particular a GSM-type network, from another terminal of the network, during a radiotelephone call that is in progress. The method makes provision for triggering a transmission stage, on the initiative of said other terminal, in which the data for transmission from a data set is transmitted via a service channel of the radio channel used by said other terminal for the call that is in progress. The terminals includes means that can be actuated at will for the purpose of extracting a stored data set and of transmitting it, as well as for the purpose of storing it on reception.
