I didn't pretend it was the only way, I was saying that there are times when one is out and needs to make reservations or call the wife that went into labour or call work after a car broke down. These were actual, real things people did back then. Thankfully I'm young enough to only have had to do it for a couple of years, but I do not have Merry England syndrome around what phones were like in the mid nineties.
Even caller id is a major win on its own.
