AT&T MMS
With the Multimedia Messaging Service (MMS) users can send messages from their mobile device to an application ("mobile originate") or an application can send messages to one or more mobile users ("mobile terminate"). The MMS content can include video, images, audio, and synchronized multimedia integration language (SMIL) formatting as well as plain text. The API uses REST and SOAP protocols. Data formats include JSON and XML.
