Multimedia Messages as used in mobile phones are some two or three pieces of media packaged together into a message. The media can be text, even formatted, sound, pictures, possibly video. The (optional, but typical) binding is done with a new and special piece of data, a Smil file.
Once an MMS has been composed, transmission is another story.
So what’s SMS? And what’s MMS?
The difference that we can see is that the size of an MMS message containing a color picture is much bigger than the size of an SMS (which normally allocates only 140 bytes of memory space).
