SMS (Short Message Service) – SMS is the English abbreviation of “short message service”. It allows users of mobile telephone services to receive several types of information on their handsets by means of a text message. More than a function, SMS is currently the most dynamic business model within the wireless mobile telecom industry. Originally, SMS was limited to sending text messages not exceeding 160 characters via GSM networks. However, as a result of its rising popularity, the use of SMS has grown exponentially. It has been estimated that the number of messages sent per month, worldwide, reached roughly 30 billion in early 2002. There are forecasts indicating that this number might rise to 70 billion over a four-year period. From the simple remittance of text and the inbound message alert function, to the availability of voice messages (and of a complementary customer support system, such as information on billing figures), SMS has evolved to the possibility of sending logos, pictures and tunes. In the same way as the arrival of SMS eclipsed paging services, it is expected that the arrival of the third mobile generation and the evolution of the concept to EMS (Enhanced Messaging Service) and later to MMS (Multimedia Messaging Service) will reveal further prospects for the use and commercial exploitation of novel services.
