Not in France actually, we mainly use WhatsApp as a main message app; nobody uses SMS nowadays

Well I do use SMS, as well as my friends and family in France.

I use WhatsApp with Belgians (I live in Belgium) because SMS's are not free for them, and also for sharing photos because MMS is a mess.

true, my point is more about the tendency of using groups of people to quickly share. Which SMS does not do properly.
