I think WhatsApp is especially popular in countries where SMS messaging was the number one means to communicate before smartphones. No idea why WhatsApp in particular won the messenger race, I don't like it and think it's a bad piece of software even before Facebook bought it, but it seems to be "fun" enough for non-savvy people to try to get into it. And it's the same here - operating their own website and handling email is too challenging for most small businesses, doctors, or contractors. But for some reason they all manage to operate WhatsApp.
