General Packet Radio Service (GPRS) was the first-ever service technology that was used to send and receive data in 2G mobile phone systems. It allows the phone companies to create a digital link to transfer the data from one source to another.
It is a method to connect to your network provider. This service is compatible both with 2G and 3G networks. GPRS comes into view as an addition to GSM. With better features and an enhanced network, this service was commercially launched in 2000.
MMS (multimedia messaging service) was one of the key features that were brought by GPRS. Internet access, walkie talkie and the modern boom of internet applications are all upshots of GPRS technology.

Since GPRS technology could not provide the mechanism to browse the Internet, Wireless Application Protocol (WAP) was developed. It is an advances protocol that runs on top of GPRS. One can also use WAP on Edge. It can even be used on the 3G connections.
WAP actually uses Wireless Markup Language (WML) that was developed by Phone.com. Browsers such as Internet Explorer, Mozilla Firefox and Apple Safari use a lot of data due to their graphic inter-phase. On the other hand, since WAP is mainly based on text with lesser graphics, it provides the necessary information without using too much data.
