wiki: MMS Multimedia Messaging Service , MMS for short, is a cellular telephone standard for sending messages that include multimedia objects (images, audio, video, rich text). MMS is an extension of the SMS standard, allowing longer message lengths and using WAP to display the content. Its most popular use is sending photographs from camera-equipped handsets, although it is also popular as a method of delivering ringtones as well. The standard is developed by the Open Mobile Alliance (OMA), although during development it was part of the 3GPP and WAP groups.
