Method and telecommunications device for transmitting and receiving service messages to and from a service centre

The present invention seeks to improve the downloading of downloadable information content that is directly or indirectly available in a service center (SZ), using a telecommunications device (TKG) to guarantee in a simple manner that the person initiating the download process bears the cost of the downloaded information content and that the service center (SZ) does not necessarily have to know or determine the subscriber's number of such person in order to transmit the information content. To achieve this, the information content is both requested from the service center (SZ), together with a first service message (SN 1 ), in a first session (SI 1 ) and is delivered by the service center (SZ), together with at least one second service message (SN 2 ), in a second session (S 12 ) via a single telecommunications like (TKV) that is set up between the telecommunications device (TKG) and the service center (SZ), without having to set up an additional telecommunications link, as is the case in prior art.
