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.

Moreover, these newer technologies also targeted network coverage layers on low frequencies, further diminishing the potential advantages of Evolved EDGE. Coupled with the upcoming phase-out and shutdown of 2G mobile networks, it became very unlikely that Evolved EDGE would ever see deployment on live networks.
The second mobile provider to shut down its GSM network (on 1 January 2017) was AT&T Mobility from the United States.

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.
Models aside from the 4G versions communicate on second-generation cellular networks only, rather than later standards such as 4G, and will no longer work when 2G networks are phased out, as has been happening since 2016 in different regions. These include: Nokia 105 (2013), released in 2013 and aimed at markets in developing nations. [1]
