> Even iPhone users in Europe tend to just use WhatsApp
Europe is not that homogenous, WhatsApp isn't even the most popular messaging app in much of Central/Eastern Europe and Scandinavia (in addition to that iOS has a similar/higher market share in Norway/Sweden/Denmark than it does in the US).
> of the history of carriers charging thru the nose for SMS back in the day.
Again, this wasn't the case in every European country (where I am text messages were already free or very cheap in the early 2010s so WhatsApp didn't really take off that much and FB Messenger is still quite a bit more popular to this day because it worked on PCs/browsers and most stuck to it when smartphones were becoming popular ).
