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 short I must confide in you to take such care of the men under you as an economical householder would of his own family, doing every thing within himself as far as he can, and calling for as few supplies as possible. The less you depend for supplies from this quarter, the less you will be disappointed.”
—Thomas Jefferson (1743–1826)
“The thief. Once committed beyond a certain point he should not worry himself too much about not being a thief any more. Thieving is God’s message to him. Let him try and be a good thief.”
—Samuel Butler (1835–1902)
“Let not the tie be mercenary, though the service is measured in money. Make yourself necessary to somebody. Do not make life hard to any.”
