2G, or second-generation cellular network technology, marks the transition from analog to digital communication in mobile networks. Defined by the European Telecommunications Standards Institute (ETSI) under the GSM standard, which became the first globally adopted framework for mobile communications, 2G was first commercially launched in 1991 by Radiolinja (now part of Elisa Oyj) in Finland.

General Packet Radio Service (GPRS), also called 2.5G, [a] is a mobile data standard on the 2G cellular communication network's global system for mobile communications (GSM). [1] Networks and mobile devices with GPRS started to roll out around the year 2001. [ 2 ]
2G (or 2-G) provides three primary benefits over their predecessors: phone conversations are digitally encrypted; 2G systems are significantly more efficient on the spectrum allowing for far greater mobile phone penetration levels; and 2G introduced data services for mobile, starting with SMS (Short Message Service) plain text-based messages. 2G technologies enable the various mobile phone ...
Cellular network standards and generation timeline. This is a comparison of standards of wireless networking technologies for devices such as mobile phones.A new generation of cellular standards has appeared approximately every tenth year since 1G systems were introduced in 1979 and the early to mid-1980s.
Typical 2G standards include GSM and IS-95 with extensions via GPRS, EDGE and 1xRTT, providing Internet access to users of originally voice centric 2G networks. Both EDGE and 1xRTT are 3G standards, as defined by the ITU, but are usually marketed as 2.9G due to their comparatively low speeds and high delays when compared to true 3G technologies.
A cellular network or mobile network is a telecommunications network where the link to and from end nodes is wireless and the network is distributed over land areas called cells, each served by at least one fixed-location transceiver (such as a base station).
