The talk is about 2G networks being shut down and the frequencies repurposed for other uses. But of course this step will take a lot more time in countries where feature phones still predominate. Perhaps Myanmar will be the first. The first 2G network was commercially launched on the GSM standard in Finland by Radiolinja (now part of Elisa) in 1991. In December 2016, Australia’s largest mobile operator Telstra closed its 2G network, which was in operation for more than 23 years.
