Here in the UK everyone just uses WhatsApp or maybe Messenger for some stuff. Even my 80yo mother uses WhatsApp, so it’s obviously not that difficult. I think it stems from data being cheaper than SMS (and media messages) back in the day and WhatsApp being more innovative with group chats, internet voice/video calls, etc.
I also lived in Hong Kong for many years and it was the same there, with everyone using WhatsApp or WeChat.
As far as I can tell, only Americans still use SMS as their main messaging system.
