What is the difference between EMS and MMS?

The following is the introduction of EMS and MMS. I believe that after reading it, you will definitely distinguish them correctly.

EMS (Enhanced Message Service) is an enhanced version of SMS, which was put forward by people at the beginning of 2 1 century. The function of this service is to send simple images, sounds and animations in addition to text. At that time, there was the concept of MMS, but due to the limitation of GPRS network or CDMA 2000 1X(2.5G network), SMS was designed as a transitional version from SMS to MMS. EMS can be sent in GSM network, which should be said to be a good technology for the transition from 2G network to 2.5G network. The biggest change in EMS support is the operator's billing system, because the number of words occupied by images, sounds and animations may vary greatly, and operators need to carefully measure them.

MMS is the abbreviation of multimedia message service, which means multimedia short message service in Chinese. This service is based on the standards of 3GPP and WAP forum. In the aspect of multimedia short message service, with the support of GPRS network or cdma2000 1X network, WAP wireless application protocol is used as the carrier to transmit video clips, pictures, sounds and words. It supports various high-speed data services, such as voice, Internet browsing, e-mail, conference TV and so on. Realize instant multimedia information transmission from mobile phone end to end, from mobile phone terminal to Internet or from Internet to mobile phone terminal. The emergence of this service can replace some functions of e-mail, and can be used as an electronic postcard to provide extremely rich services. The biggest obstacle to the development of this service is the speed limit of the current 2.5G network. Slow network speed directly leads to high tariffs. Although the price has dropped a lot, it is still unbearable for most users.
