Multimedia Messaging Service (MMS) is a standard service for sending multimedia content between mobile subscribers. It was developed by the Open Mobile Alliance (OMA) and 3GPP.
Multimedia messaging is also known as picture messaging.
MMS allows mobile subscribers to send multimedia files such as images, videos, audios, etc., as a message.
It extends the limited capabilities of the Short Messaging Service (SMS), which only supports text messages, and the Enhanced Messaging Service (EMS), which can only send simple media files between subscribers. There is no specified size limit in MMS except that enforced by the mobile carrier. MMS requires 2.5G or higher mobile communications technology to work.
