> In Europe you'll find people using WhatsApp or Telegram

For whatever reason, in my country, everybody use FB Messenger for the absolute majority of their texting. And by "everybody" I mean teenagers, young adults, parents and the elerderly.

It's only if you've had prolonged stays in other countries (or is exposed to international communication in other ways) that people will be familiar with WhatsApp and I'd guess that very few have ever heard of Telegram here.
