Thanks for this interesting tip. I looked into it and it sounds very good, but only available on Android (and only on the Nexus 5X & 6P phones). I'm going to stick with Apple (though I have thought of switching someday). There is some confusion whether Google Fi has access to T-Mobile's new band 12 spectrum yet.
If anybody is considering upgrading an Android device I suggest you check it out. You are welcome to start a new thread to poll your fellow waccos for their experience.
