Short Message Service (SMS)

Short message service (SMS) is a facility developed as part of the GSM standard that enables a mobile device to send, receive and display messages of up to 160 characters in Roman text and variations for non-Roman character sets. Messages received are stored in the network if the subscriber device is inactive and are relayed when it becomes active. SMS has become available increasingly in CDMA networks and in some fixed networks.
