I send maybe one SMS per year, not every year, when I think a person could be offline or in low signal areas. SMSes get where data don't.

I receive dozens of SMSes from banks with one time passwords for 2FA and payments notifications, from delivery companies to notify me about progresses in my orders plus some spam. It's easier for them to use SMS than anything else because every phone receives SMS right out of the box.
