What is MMS?

MMS stands for Multimedia Messaging Service, a technology that allows you to create, send, and receive text messages that also include an image, audio, and/or video clip. MMS messages are sent from one mobile phone to another, or to an email address.

In one way it extends SMS which allowed to send message up to 160 characters in length.

During development it was a part of 3GPP and WAP group.
