Short Message Service (SMS) is a text messaging service component of phone, Web, or mobile
communication systems. It uses standardized communications protocols to allow fixed line or mobile
phone devices to exchange short text messages.
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 other mobile technologies, such as ANSI CDMA
networks and Digital AMPS, as well as satellite and landline networks.
