Google launched Project Fi in 2015. It has been renamed Google Fi. It is now available on more phones. Their plan works with the majority of Android devices and iPhones.
You can now sign up for Google Fi with popular Android phones (including many Samsung, LG, Moto and OnePlus devices) and with iPhones (in beta). Google says there are some extra steps involved for iPhones, and they will walk you through it in the Google Fi iOS app.
A Google Fi plan starts at $20/month for unlimited calls and texts. Get exactly how much data you need for just $10/GB until 6 GB. After that, Google Fi’s Bill Protection caps your bill and data is free for the rest of the month. (It is worth noting that “Data is slowed when individuals have used more than 15 GB in a month.”)
Google Fi also offers 4G LTE coverage from coast to coast. If you are using a phone designed for Google Fi, your phone will keep you on the best signal by shifting between three mobile 4G LTE networks and automatically connecting to 2 million+ secure Wi-Fi hotspots. Visit the Google Fi website to find out if your current phone is compatible with Google Fi.
It seems to me that Google Fi might be an option for people who are completely fed up with the plan they currently have on their phone. Maybe.
The Verge reported that Google Fi is an MVNO, (mobile virtual network operator), which means the Google Fi service actually comes from larger carriers Google Fi uses – like T-Mobile, Sprint, and US Cellular. So, if you don’t happen to like one (or more) of those carriers, switching to Google Fi won’t necessarily separate you from them.
Whether or not you choose Google Fi might be influenced by how much (or how little) you trust Google with your data. Earlier this year, the Wall Street Journal reported that Google exposed the private data of thousands of users of the Google+ social network. The Wall Street Journal said Google discovered it in the Spring of 2018, but did not disclose the issue at that time.
