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.
