3G is only now starting to be sunset by wireless operators but for 4G it’s
a different story all together and it’s possible 4G may never sunset.

The major issue with 5G is right now with most 5G carriers urban densely
populated areas are the only areas where you will be able to get 5G.
Because 4G also has 4G+ which is the transition to 5G, 4G+ 4x4 MIMO is
still not even available yet in dense areas which gives up to GiG speeds
and 5G 10G speeds will start with densely populated urban areas but it’s
not available anywhere yet by any mobile operators.

Just as LED TV manufacturers came out with 4K well before cable operators
started delivering 4K and still lagging same goes with 5G the handsets and
fixed manufacturing comes way before the network is ready for primetime.

Also 3G surprisingly lingered for quite a long time and only now wireless
operators are now starting to shutdown 3G.  It’s going to be a very long
time before 4G or 4G+ becomes legacy and a think in some cases rural areas
may remain indefinitely as 5G has been targeted by wireless operators for
densely populated urban areas.  I would count on 4G and 4G+ being around
almost indefinitely.
