Abstract: The invention relates to a method and a system for transmitting an electronic short message via at least one telecommunication network (N) from a first terminal device (D) for telecommunication to a group of two or more receiving devices (A, B). The short message is received by a messaging center (C) and the latter sends this short message as single messages to the receiving devices (A, B).
