What is mobile MMS?

SMS-short message service is the earliest short message service and the most popular short message service now. At present, SMS only creates a paragraph of text in the mobile phone and sends it to friends, which is simple, convenient and easy to use. The length of this short message is limited to 140 bytes. Short message is welcomed by the public because of its simple and convenient use function, but it is always the first generation of wireless data service, and its content and application are limited by technical standards.

EMS-enhanced information service. The advantage of EMS is that it can not only send text information like SMS, but also send simple information such as images, sounds and animations. It can still run on the original SMS network, and there is no difference in sending mode and operation. The standard is open, and any third-party company or individual interested in EMS can develop application software and services on this platform.

MMS means multimedia short message service. MMS is similar to SMS and EMS in concept, which can be understood as the evolution from SMS to multimedia. But unlike SMS and EMS, MMS has almost no restrictions on the size or complexity of information content. MMS can transmit not only text information, but also images, videos and audio. Therefore, the biggest change brought by MMS is that operators can develop more diversified mobile communication services. MMS can not only send and receive MMS, but also send and receive emails containing attachments. From the user's point of view, multimedia applications will be the key to attract them to use.
