2G is still strong in Germany as some industrial applications rely on it. It is not going to be deprecated any time soon. Maybe once they run out of spare parts.
Germany's mobile network is worse than most third world countries. Working on a train? No internet for you! Going a few meters outside a settlement? Might not even be able to do calls.
Such an exaggeration. >92% of the area is served with 5G. Calls are available in 98%-99% of the area (though sometimes just from one of the operators). Some trains were built in a way that blocks reception, though those have had repeaters or wifi for a while. I know plenty of people who work from the train every day.
