  1G is important. Most emergency services are based on it.

    2G defines basic mobile services, for example telephone or SMS.

    3G, 4G etc. added internet to it, but there they are interchangeable. Each new one replaces the former if you use only the internet service. But none of them replaces 2G.

      It’s more that all should be backwards compatible, so if you have 5g then you still have 2g and it gives you the bare minimum voice and some scraps of data.

      They can reclaim all the spectrum for 3 and 4g (which is a lot) for 5g, while leaving some of the barest functions working for stuff that doesn’t need real data.

        You can read in the spec why they chose not to be backwards compatible. The cons were too great.

        Nice thought, but 5g does not have the same range.
