MMS - Multimedia Messaging Service

MMS is similar to SMS in the way it allows people to communicate by sending messages. However, SMS is just a simple way to send a short message to a contact, whereas MMS allows you to send images, sound, text pages and videos.

MMS was first used in Japan when camera phones first come out. At first there were a few technical difficulties in opening the picture message that you had received because it was in a different format to what the phone would usually be compatible with.
