This is how Project Fi billing works

Project Fi is an interesting new carrier choice with some great features, like access to two mobile networks and Wifi calling, but perhaps its greatest draw is the way it bills you for service. It’s not unlike many prepaid carriers in that it charges you up front for service that you use in the month, but the way Fi refunds you for unused data, doesn’t charge extra for overages, and gives you a clear and concise bill is intriguing.

We’ve used Project Fi for over a month now, and finally have two full bills to look at and see just how easy the billing process is. This is how it goes down when its time to pay Google for phone service.
