Yup, that you do, and crazy it is. What you're supposed to do is get the unlimited text plan so that it doesn't matter. If you don't use SMS enough to justify the $20/month for unlimited, too bad for you (at least for AT&T I'm pretty sure it's unlimited or $0.25/text these days, with nothing in between). Or just do what I did and switch to T-Mobile.

Or do what I did and switch to a data-only plan. I like having my mobile provider be nothing more than a dumb pipe.

How do you make calls? I used to use Talkatone with Google Voice but the api they used was discontinued.

You could use a paid VOIP provider like Voip.ms and make calls over your data connection. It's the same concept, except you're paying $0.01/minute instead of nothing.

FaceTime audio, VoIP, textPlus, Skype, etc.

I used Google Voice via Talkatone as well, but they offer their own VoIP solution now that the 3rd party GV API is discontinued.
