MMS is a standard for telephony messaging systems that allows sending messages that include multimedia objects (images, audio, video, rich text) and not just text as in Short Message Service (SMS).
MMS-enabled mobile phones enable subscribers to compose and send messages with one or more multimedia parts. However, sender and reciever must have mobile devices that conform to the MMS Standards. For example a sender using a Mot V3 can send a video clip, but a BB8700 user who is receiving the MMS may not be able to interpret it. Mobile phones with built-in or attached cameras, or with built-in MP3 players are very likely to also have an MMS messaging clientxxx8212;a software program that interacts with the mobile subscriber to compose, address, send, receive, and view MMS messages. . . .
