Multimedia short message (English: Multimedia Messaging Service, abbreviation: MMS) is the function of transmitting multimedia information such as text, picture, animation, audio and video. China Mobile calls it "MMS". This is a way for mobile phones to receive and send multimedia messages. Compared with short messages which can only transmit 160 characters, multimedia short messages expand the length of sending and receiving text.

The most popular use of multimedia text messages is to send photos through mobile devices with cameras, which is also a common way to transmit news and entertainment information, including video and ringtones.

In the past, the size of multimedia messages was usually 50KB, which was determined by both operators and mobile terminals. Now most mobile phones can support 300KB's MMS. Pictures, background music and text messages can be added to MMS.

The information is then forwarded to the MMS storage and sending server (called MMSC,Multimedia Messaging Service Center).
