Abstract: A system (1) which allows content providers of value-added SMS services to set-up their own services comprises a Small Message Entity Agent (SMEA) (6) which is coupled to a Short Message Service Centre (4) of a cellular radio telephone network. Providers of value added services can access the SMEA to register a unique identifier in the form of an easily remembered name, which is then translated into a numerical number, which is used as part of the destination address in text messages destined for the content provider. The content provider is able to self-configure his service so that text messages delivered to the SMEA are forwarded to selected message handlers for forwarding to appropriate destinations, such as email addresses, pagers or mobile phones.
