SMS...Short Message Services

         

                                                   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.
