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 text messaging is the most widely used data application in the world, with 3.6 billion active users, or 78% of all mobile phone subscribers. The term "SMS" is used as a synonym for all types of short text messaging, as well as the user activity itself, in many parts of the world. SMS is also being used as a form of direct marketing known as SMS marketing.
SMS as used on modern handsets originated from radio telegraphy in radio memo pagers using standardized phone protocols and later defined as part of the Global System for Mobile Communications (GSM) series of standards in 1985 as a means of sending messages of up to 160 characters, to and from GSM mobile handsets. Since then, support for the service has expanded to include other mobile technologies such as ANSI CDMA networks and Digital AMPS, as well as satellite and Landline networks. Most SMS messages are mobile-to-mobile text messages, although the standard supports other types of broadcast messaging as well.
Famous quotes containing the words short, message and/or service:
“In my short experience of human life, the outward obstacles, if there were any such, have not been living men, but the institutions of the dead.”
—Henry David Thoreau (1817–1862)
“All this is from God, who reconciled us to himself through Christ, and has given us the ministry of reconciliation; that is, in Christ God was reconciling the world to himself, not counting their trespasses against them, and entrusting the message of reconciliation to us.”
—Bible: New Testament, 2 Corinthians 5:18-19.
“In the early forties and fifties almost everybody “had about enough to live on,” and young ladies dressed well on a hundred dollars a year. The daughters of the richest man in Boston were dressed with scrupulous plainness, and the wife and mother owned one brocade, which did service for several years. Display was considered vulgar. Now, alas! only Queen Victoria dares to go shabby.”
—M. E. W. Sherwood (1826–1903)
