Short Message Service

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 service, short and/or message:

    We could not help being struck by the seeming, though innocent, indifference of Nature to these men’s necessities, while elsewhere she was equally serving others. Like a true benefactress, the secret of her service is unchangeableness. Thus is the busiest merchant, though within sight of his Lowell, put to pilgrim’s shifts, and soon comes to staff and scrip and scallop-shell.
    Henry David Thoreau (1817–1862)

    You’re too short for that gesture. Besides, it went out with Mrs. Fiske.
    Joseph L. Mankiewicz (1909–1993)

    Gossip, then, is content, a message about people; rumor is a process. It takes a bit of gossip and reshapes it, modifies it in some way, and passes it along from individual to individual in different ways.
    Jack Levin (b. 1941)
