Mostly badly. I remember the thrill of printing MapQuest directions and if you missed an exit, your passenger then had to pull maps out of the glove compartment and start comparing them and the directions to find out the easiest way to return to your route. And hell, that was after MapQuest which in itself is Internet-based. I also recall vaguely being a kiddo when we would do family road trips, and my grandpa would navigate in the passenger seat with 2 or 3 different maps on his lap, switching between them as needed for a better look at wherever we were going.
I also remember my last truly "analog" friendships were in an apartment complex I lived at before we moved elsewhere and got our first internet connection. I have no earthly idea where any of those people are today, hell I don't even remember the school that well. We basically never "arranged" anything, and I mean, it's not like we were incapable, but we had no ways of contacting one another outside of when we'd meet at school or the bus stop. If a friend of yours was sick at home, you just didn't know what was happening with them for that day at all. Or, hell, if someone moved, unless they announced it ahead of time, that person who you might've been deeply acquainted with just vanished from the world one day, or over one particular summer.
Even as someone who technically spent the vast majority of their childhood without much technology, I don't recall really having many friendships until my first email account and later, flip phone with SMS enabled some manner of autonomous communication for me. Not sure if that's everyone's experience but it was certainly mine.
