Unfortunately they will probably not answer the phone because the phone number will be hidden or say unknown, or no caller ID. They’re working on that, but for now just assume everyone who answers suspects you’re a telemarketer.
If you’ve got Google Voice or Project Fi supposedly you can finagle a way to show your name and number on caller ID. As with all things, I’m assuming somehow the Sprint integration probably was botched, overlooked, and otherwise will not work.
So yeah, go ahead and get your “I can’t hear you the Google Home is on a shelf” excuse ready when someone asks you to bring your truck over and help them move.
