In the 70s and 80s I ran a business on the road from phone booths and motel phones. Is it easier now? Absolutely but it's obvious that it all got done before the advent of the internet and cell phones. I still remember my first cell phone: Had a regular handset and a keypad. Weighed about 5 lbs. Just about zero coverage. Had to use phone booths most of the time. The range on that thing was about as far as I could throw it.
