This messaging app was the most reliable feature when I didn't get reliable coverage. NOW... UGH!! I'm not sure what's happened or what's been "improved," but many times, there is such a lag when sending messages. Whether they're simple texts or sending media. - There's a lag from "queued" and an even bigger delay when "sending." And often, there's a complete failure altogether. Either fix it or just go back to your basics. I would hate to use a different messaging app.
