Whatever Happened to WAP?
So it's technically possible they could have been browsing smutty Internet web sites (well, WAP sites anyway) in "glorious" (cough) WAP text.
But now that I think of it, they wouldn't have been doing so through their employer's WiFi- if they'd had WiFi at all, which they probably didn't back then, so that torpedoes my smartassery.
As does the fact I don't think anyone ever actually used WAP when they realised that "the Internet on your phone" back then was less "Hackers"-style zooming through cyberspace and more being limited to a paltry number of specially-designed WAP sites you read through five lines at a time and attempted to navigate via an SMS-style numeric keypad while you paid through the nose for a per-minute connection.
You're right- that would have been pretty hard. And unpleasant. And unlikely.
