When I travelled internationally in the 1990s—so maybe 30 years—I was pretty much unreachable. I’ve never had an EPIRB. And didn’t really have a routinely connected cellphone until probably 25 years ago or so when I got a Treo.
I had a cellphone earlier but it was something I used rarely.
Laptop connectivity was still pretty awful in the 1990s and even early 2000s. Conference WiFi was something of a joke. You were still often still using Dial-up. It’s probably in the last 20 years or so that cell and WiFi have become pretty much a utility in most cases. Which is a while but I remember when they weren’t.
