>Every other country has settled on either Telegram, WeChat, WhatsApp or FB Messenger, or other niche apps. These apps work on both iOS and Android and often also Windows. I haven't sent an SMS in probably 12 years. I don't know anyone who has.

SMS is big in Europe (yes, Europe is not a country. I just mean "dozens of countries in Europe"). All courriers have plans with SMS focus.
