I thought traditional SMS was purely a 2g or maybe 3g thing, and it is absent from 5g, though maybe simulated somehow. Amirite? I know MMS has been around for a while and it seems harder to escape from now. Even voice service is now done through the internet pipe, though maybe it has special routing at the carrier level.
SMS may have been marginal/best effort in the past but it would have been better to make it more robust and make work in places with not enough signal to handle voice/data, not convert it to video.
Voice and data services are separate in the radio network. 4G and beyond does not change that. It’s part of the Global System for Mobile Communications (GSM) standard.
Actually, text messages are more robust in some ways. But, your packets are going to a centralized server which forwards them on.
