It's similar in Japan. Everyone here uses LINE, and AFAICT, absolutely no one does SMS texting any more. I don't even know the phone numbers of any of my friends here; everyone just exchanges LINE contact info by QR code and that's it. The only time anyone uses a phone number seems to be for non-personal purposes (e.g., calling a business or government office), and the only time SMS seems to get used is for automated messages from official places (like your utility companies).

A lot of people here have iPhones, but it's not because of some stupid blue bubble.

What's funny is that Americans will sometimes make fun of Japan because some people (mainly businesses, maybe some elderly people) still use FAX, but Americans are the ones who are all still using SMS.
