Apples and oranges. I'd never use text on a phone for any kind of long conversation; it's just for quick messages, synchronizing meet-ups, and such. Part of it is that I don't enjoy reading or writing on a mobile device; it's a kind of second-class experience. Part of it is certainly that my patterns of availability have changed.

And part is because someone's status could give you insight into whether they'd like to talk or not before you sent a single message. Maybe some of the modern mobile-oriented systems still do that? I don't know; I don't have any friends that use them.
