The invention relates to a circuit arrangement for a data connection for mobile radio subscribers to transmit non-voice information, in particular videotex information. A circuit arrangement of this type is intended to enable interference-protected data transmission from and to mobile subscribers and ensure simple and space-saving design of the corresponding devices. For this purpose, the invention provides that a videotex modem (V) is additionally disposed in the subscriber device of the mobile radio subscriber which contains transceiver devices (I, II) and operating and control components (III, IV). This modem is connected to the operating and control components (III, IV) and can be connected to the transceiver devices (I, II) via mode changeover switches (16, 17) which are disposed in the connection path between the transceiver devices (I, II) and the operating component (III). The videotex subscriber identification via subscriber identity pass and the functional testing of the videotex modem (V) have a connection panel to connect a videotex decoder or a different terminal device. <IMAGE>
