A mobile radio handset (10, 24), capable of receiving short message service text messages (12), examines incoming text messages (12) to see if a recognised string of one or more characters is received and, in response thereto, retrieves and displays, on a display screen (14), a stored image (26, 28, 30, 32, 34) which is to be displayed whenever that string of characters is received. The image (26, 28, 30, 32, 34) can be shown alone or with the text (12) which triggered its display. The images (26, 28, 30, 32, 34) can be provided by the user of the handset (24), or derived from a server or central data base (80) in the mobile telephone network. The images (26, 28, 30, 32, 34) can include static images or animations. The static images can includes a photograph. As well as text messages (12), the Caller Location Identifier (CLI) of a caller can be used to evoke a display, chosen by the call recipient. The operation of the invention is compatible with handsets (10, 24) which can receive text messages (12) but which are not enabled for the invention. |
