Multimedia Messaging Service (English: Multimedia Messaging Service, abbreviation: MMS) is a function of transmitting multimedia information such as text, pictures, animations, audio and video. China Mobile calls it "MMS". This is a way for mobile phones to receive and send multimedia information. Compared with text messages that can only transmit 160 characters, multimedia text messages extend the length of text sent and received.

The most popular use of multimedia text messaging is to send photos through mobile devices with cameras. It is also a common way to send news and entertainment information including videos, ringtones, etc.

In the past, the size of multimedia text messages was usually 50KB, which was determined by both the operator and the mobile phone terminal. Most mobile phones now support 300KB MMS messages. Pictures, background music and text messages can be added to MMS messages.

Technology

The transmission method of multimedia messages is completely different from text messages. The first step is for the device to encode the multimedia message (similar to MIME mail). The information is then forwarded to the MMS storage and sending server (called MMSC, Multimedia Messaging Service Center).

Security

Some malicious MMS messages can cause the phone to freeze or be poisoned. According to information security researchers, a vulnerability called Stagefright allows an attacker to completely control your phone without any interaction as long as you receive a specially crafted MMS message [1].
