<p>A system and method which enables an efficient filtering of data messages transmitted within a mobile telecommunication network is described. A mobile user 150 may request a service from a service provider 210 by sending as SMS message comprising one or more keywords to his own handset number. The message is intercepted and routed to the service provider. In an embodiment, the service may be a message backup service. In one embodiment, a message from a first user to a second user is intercepted and routed to the service provider, which adds text to the message and forwards it to the second user. If the second user sends a reply to the modified message including one or more keywords back to the first user (message chain), the reply is intercepted, interpreted as a service request and routed to the service provider.</p> |
