A text message is identified by an SMS router ( 16 ) by means of message attributes, such as addressing, address type, message content or signalling fields, as belonging to one of a number of different categories, each category relating to a specific messaging application. The identified messaging application may be executed by a message transformation means ( 22 ) which may parse, interpret and transform the message content and addressing in order to generate a response message. The response message may be generated according to a programmable table of exceptions, the exceptions conforming to a syntax permitting matching of a single exception to multiple forms of message construction. The message transformation means ( 22 ) and SMS router ( 16 ) may return the response message without requiring a routing query to an HLR ( 28 ), the response message addressing and routing information being instead derived from the original message.
