In a mobile telecommunications system (100) capable of transmitting
message data a sending device (102) and a receiving device (106) may have
different message data handling capabilities. By informing the sending
device of the message data handling capabilities of the receiving device,
the user of the sending device can select the message data to be
transmitted to the receiving device on the basis of these capabilities.
In this way it is avoided that a device receives message data it cannot
handle or that the network (104) has to transcode the message data.
