I can't remember exactly how much it was, but within the last year, I ran out of cellular data and my "unlimited" plan dropped back to a lesser amount of bandwidth, but still what used to be broadband. However, I literally could not load any website I tried. However much it was, it was way more than dialup. It seemed to me like there was no point in a soft cap, if one can't even load the website to change plans.

I would hazard a guess that it was 2G. And yes, it's absolutely infuriating that so many basic services (which used to be implemented just fine on 2G speeds (or less!)) no longer remotely function without LTE.
