2G and 3 G is a family of standards for mobile telecommunications defined by the International Telecommunication Union,which includes GSM EDGE, UMTS, and CDMA2000 as well as DECT and WiMAX. Services include wide-area wireless voice telephone, video calls, and wireless data, all in a mobile environment.

2G Stands for second generation mobile telephony standards, where 3G defined the third generation  mobile telephony standards to facilitate growth, increase bandwidth, and support more diverse applications.For example, GSM (the current most popular cellular phone standard) could deliver not only voice, but also circuit-switched data at download rates up to 14.4 kbps. But to support mobile multimedia applications, 3G had to deliver packet-switched data with better spectral efficiency, at far greater bandwidths.
