SMS Chat
Short Message Service (SMS) is a text messaging service component of phone, web, or mobile communication systems, using standardized communications protocols that allow the exchange of short text messages between fixed line or mobile phone devices.
SMS is the most widely used data application in the world, with 3.5 billion active users, or 78% of all mobile phone subscribers. The term "SMS" is used as an acronym for all types of short text messaging and the user activity itself in many parts of the world. SMS is also employed in direct marketing, known as SMS marketing.
SMS as used on modern handsets originated from radio telegraphy in radio memo pagers using standardized phone protocols. These were defined in 1985 as part of the Global System for Mobile Communications (GSM) series of standards as a means of sending messages of up to 160 characters to and from GSM mobile handsets. Though most SMS messages are mobile-to-mobile text messages, support for the service has expanded to include such other mobile technologies as ANSI CDMA networks and Digital AMPS, as well as satellite and landline networks.

Famous quotes containing the word chat:
“A few more days, and this essay will follow the Defensio Populi to the dust and silence of the upper shelf.... For a month or two it will occupy a few minutes of chat in every drawing-room, and a few columns in every magazine; and it will then ... be withdrawn, to make room for the forthcoming novelties.”
—Thomas Babington Macaulay (1800–1859)
