The SMS messages of a mobile telephone are used to call up information which is unconnected in time and location with the mobile telephone. To specify the desired information and to define the brief commands the user of the mobile telephone uses data-processing equipment with data lines to the information provider, e.g. Internet connection, by means of which he can deposit query profiles with the information provider. In addition, the query profiles can be produced using a speech computer. The user can call up the dormant query profiles by means of simple brief commands and obtain the required information. The desired information will be reproduced either visually or acoustically via the mobile telephone. The advantages of both communication media are therefore combined with one another in an ideal manner, where the hardware of the mobile telephone and/or its method of operation remain unchanged.
