I had no smartphone up until like 2012 (and even afterwards for some time I didn't have mobile data, just WiFi when available). It's sometimes inconvenient and you may "lose" quite some time for sure (e.g. miss a train because you could not check a platform change). But for sure you can manage reading off street signs, looking at maps and perhaps asking passers-by. Asking for directions used to be a very common superficial interaction even in the socially "coldest" countries and it is very rarely happening anymore. Asking for directions was also one of the first things you learned in a foreign language. For timetables you can just go and check the physical timetable at the station. Buy tickets at the station. Surely less convenient, but I'm pretty sure you'd manage, just like everyone did. It was just a few years ago.
