SMS stands for short message service, which is often called text messaging.

SMS is a mean of sending short messages to and from cellular phones. It originated in 1985 as part of the GMS series of standards and was a way to send messages of up to 160 characters between mobile handsets.

Support for this technology has extended to include CDMA networks, satellite and landline phones.

The idea of adding text messaging was a part of mobile communication services since the beginning of the 1980s.
Experts decided on which of these services should be GMS services (a global system for communication systems). At the time, few believed that SMS would be used to send text messages from one mobile user to another and believed it would be used to alert the individual mobile user that he or she had a deposited voice mail or that it could be used for telemetry.

A plan was reached to allow SMS in mobile phones around 1985. The first SMS message was sent in the UK in 1992 using a personal computer and sending the message to a Vodafone Orbitel handset. The text of the message was “Merry Christmas.” The first growth of SMS was slow with customers sending only 0.4 messages per month.

SMS is he fastest form of communication when one includes the counterpart not being able to take a call, being out of radio range, etc. Currently SMS has an average global price of 11 cents and maintains a near 90% profit margin.

SMS-Point to Point service is defined in GMS recommendation
03.40 and GMS 03.41 defines the SMS-Cell Broadcast which allows advertising and public information to be broadcast to all mobile users in a specified geographical area. Messages are sent to an SMS Center which provides the store-and-forward mechanism. If not able to send the message immediately, it attempts to send messages later.

Some SMS Centers will try the transmission only once. Both Mobile Terminated (sent to a mobile handset) and Mobile Originated (sent from a mobile handset) operations are supported. Currently message delivery is done on a “best effort” basis which means there are no guarantees that a message will actually arrive at its destination.
