Abstract: A mobile communication device utilizes the short message service of its communication network to generate messages. The messages are constructed from a series of fields. From stored data a series of questions and optional answers are pressented. The user can select the appropriate answer from the memory. Each of the answers is correlated to a message component which are compiled by the microprocessor to form a complete message.

Abstract: The invention relates to the use of intelligent network services from a terminal (3) of a telecommunication network and particularly to the introduction of new services and a programmable user interface of a terminal. A service provider (5) programs service functions in a switching centre (1) of a telecommunication network and delivers to a user a program which is loaded in the user's terminal (3). According to the loaded program the terminal, advantageously a telephone apparatus equipped with a display (7), shows to the user the available services and the corresponding commands assigned to the function keys (8a) of the terminal. The user gives the required commands which advantageously are one-push-of-a-button long and the meanings of which at each particular situation are shown on the terminal's display. Advantageously the program is delivered to the user by loading it in an intelligent card (6) controlling the operation of the terminal.
