Multimedia Messaging Service (MMS) is a technology for transmitting not only text messages, but also various kinds of multimedia content (e.g. images, audio, and/or video clips) over wireless telecommunications networks using the Wireless Application Protocol (WAP). It is standardized by 3GPP and 3GPP2. MMS is the evolution of Short Message Service (
SMS). With MMS, a mobile device is no longer confined to text-only messages. It can send and receive multimedia messages such as graphics, video and audio clips, and so on. It has been designed to work with mobile packet data services such as GPRS and CDMA 2000 1x.
MMS-enabled mobile phones enable subscribers to compose and send messages with one or more multimedia parts. Mobile phones with built-in or attached cameras, or with built-in MP3 players are very likely to also have an MMS messaging client -- a software program that interacts with the mobile subscriber to compose, address, send, receive, and view MMS messages.
