TBH I forgot that I had this discussion elsewhere and I’m about 99% sure that these phones simply become unusable when 2G is shut down, which is why some countries shut down 3G but not 2G. But I don’t remember or understand the technical stuff behind it.
There’s also somehing about these specs that we just call 2G or 3G etc., in reality it’s much more complex.
