The use of SMS is a US oddity. The rest of the world is using almost only messenger apps: Line or WeChat if you’re in Asia, WhatsApp or telegram in Europe or South America.

euro here, used sms heavily until the ott messenger craze set in my cicles (~2015).

nowadays mostly for contacts that either dont use a smartphone or dont have mobile internet connection (yes! those exist).

are u sure u are using sms? asking because apple overlays imessage and iphone penetration is said to be highest in usa.

I largely only text my partner and that's through Whatsapp. My friend group has a Discord we all use.
