Because EMS is based on SMS, it can use SMS
centres the same way that SMS does. EMS works on
all Global System for Mobile communications (GSM)
networks. EMS senders can use text, melodies,
pictures, sounds, and animated images to enhance
the expressive power of messages that are
otherwise limited by the display constraints of
mobile devices.
GPRS (General packet radio service)

cellular phone connections and the Short Message
Service (SMS).
GSM (Global system for mobile
communication)
International standard for cellular communication,
