This is a most excellent place for technology news and articles.
I've been waiting for average users to catch up since about 2010 when I was running Pidgin (XMPP) on my Android, since SMS is terribly unreliable.
SMS is a best-effort protocol, with zero error checking, meaning no error correction, no ensured delivery. It's known to lose up to ten percent of messages.
It's also tightly bound to cellular architecture, since it encapsulates messages into the mostly-empty management frames of the cell network.
It was bleeding edge in 1986 (IIRC), but it's long past it's retirement time.
