Short Message Service (SMS), according to Wikipedia, is a communication protocol allowing the interchange of short text messages between mobile telephone devices. SMS text messaging is the most widely used data application on the planet. The SMS technology has facilitated the development and growth of text messaging. The connection between the phenomenon of text messaging and the underlying technology is so great that in other parts of the world the term “SMS” is used as a synonym for text message or the act of sending a text message, even when a different protocol is being used.

SMS was originally designed as part of GSM, but is now available in a wide range of networks. Today, commercially SMS is a massive industry worth billions of dollars globally.
