The 2G shutdown has been planned for a few years and judging by the lack of outcry from Apple fanboys when the network stopped working there can’t be many people still able to get Steve Jobs’ pivotal shiny toy to go. To be fair it is ten years and Apple normally expects people to replace their phone after one.
AT&T notes that the 2G shut down will free up resources and spectrum bandwidth for the network to use for future rollouts of more advanced wireless solutions like 5G down the line.
Of course, the Apple fanboy could move to Blighty, where 2G is still going. In fact some remote areas are only covered by 2G because it is reasoned that some coverage is better than nothing.
Even within more urban and populated areas that have substantial 3G coverage, there is still a large dependence on the reliability of 2G.
