What is SMS?
SMS is Short Message Services (SMS) is a communication protocol allowing the interschange of short text messages between mobile telephone devices. The SMS technology has facilitated the development and growth of text messaging. The connection between the fhenomenon of trext messaging and the underlying technology is so great that in parts on the world
the term SMS is used colloquially as a synonym for a text message from another
person or the act of sending a text message (even when, as with MMS, a
different underlying protocol is being used). SMS as used
on modern handsets was originally defined as part of the GSM series of
standards in 1985 as a means of sending messages of up to 160 characters
(including spaces), to and from GSM mobile handsets. Since then, support for
the service has expanded to include alternative mobile standards such as ANSI
CDMA networks and Digital AMPS, as well as satellite and landline networks.
Most SMS messages are mobile- to- mobile text messages, though the standard
supports other types of broadcast messaging as well.
