EMS (Enhanced Message Service) is an enhanced version of SMS, a concept that was introduced at the beginning of the 21st century, with the ability to send simple messages such as images, sounds and animations in addition to text. The concept of MMS already existed at that time, but due to the limitations of MMS requiring the popularity of GPRS networks or CDMA 2000 1X (2.5G networks), SMS was designed as a transitional version from SMS to MMS. EMS can be sent on GSM networks, and it should be considered as a good technology for the transition from 2G to 2.5G networks. The biggest change required to support EMS is in the operator's billing system, as the number of words taken up by images, sounds, animations, etc., can vary greatly, and operators will need to weigh this carefully.
MMS stands for Multimedia Messaging Service and is based on the standards of the 3GPP and the WAP Forum. In terminology, Multimedia Messaging Service is the transmission of video clips, pictures, sound and text with the support of GPRS network or cdma2000 1X network, using WAP wireless application protocol as the carrier. It supports a variety of high-speed data services such as voice, Internet browsing, e-mail, conference TV, etc., and realizes instant end-to-end cell phone, cell phone terminal to Internet or Internet to cell phone terminal multimedia information transmission. The emergence of this kind of service can replace part of the function of e-mail, and can be used as the electronic version of postcard, providing extremely rich service content. The biggest obstacle to the development of this kind of business is the limitation of the current 2.5G network speed, the slow speed of the network directly leads to the high tariffs, although the price has dropped a lot, but still most users can not afford.

GPRS is the English abbreviation of General Packet Radio Service (GPRS), which is a new packet data bearer service developed on the existing GSM system. the most fundamental difference between GPRS and the existing GSM voice system is that GSM is a circuit-switching system while GPRS is a packet-switching system. GPRS is a packet switching system. Therefore, GPRS is particularly suitable for intermittent, bursty or frequent data transmission of small amounts, as well as for occasional transmission of large amounts of data. This characteristic is just right for most mobile interconnection applications.
