MMS stands for Multimedia Message Service.
The Multimedia Message Service (MMS) is a standard defined by The Open Mobile Alliance (originally by the WAP Forum) for sending and receiving messages with rich content, from user to server to user, over mobile telephony networks.
- MMS operates over dial-up (CSD) or GPRS connections.
- It uses WAP or HTTP for message transports and notifications.
- MMS messages are similar to MIME email messages.
- They contain headers that define the message properties, and a MIME body.
- The format for MMS messages is MIME
- The MMS message contains a number of media objects, such as pictures, sounds and text.
- The first object is expected to be a Synchronized Multimedia Language (SMIL) file, an XML document that provides instructions to the client about how to present the other media objects in the message.
