I signed up for an invite, but honestly I don't see why I'd want this over my current service, Ting, which does basically the same thing (an pay-what-you-use MVNO with nice app integration) and is already available for any band-capable phone (I'm using a T-Mo iPhone 5S right now). And, there is a WiFi calling toggle in the app that was off by default for me. In all honestly I'd rather use less Google-things than more. The typical month costs me $26 before taxes, by the way.
