Google has finally announced it’s own mobile network (Project Fi) that will use Sprint and T-Mobile to provide a constant connection to your mobile device. The service is currently available through invite only and Google’s Nexus 6 is the first phone that is supported by network.

Network

Networks change in quality as you move around. To help you get the highest-quality connection at your location, Project Fi uses new technology to intelligently connect you to the fastest network whether it’s Wi-Fi or one of our partner LTE networks.

If you’re on one network and we detect our other 4G LTE network partner has a stronger signal, you’re moved over to the other network to get the fastest available speed.

The Nexus 6 is the first smartphone to support Project Fi’s network of networks. The Nexus 6 works with our unique SIM that lets you access multiple networks and has a state-of-the-art cellular radio tuned to work with different network types. You can use a Nexus 6 you already own, or buy a new one when you sign up.

Plan

Our plan starts with the Fi Basics for $20 per month. This includes:

Unlimited domestic talk and text
Unlimited international texts
Low-cost international calls
Wi-Fi tethering
Coverage in 120+ countries

Then it’s $10 per GB for data. $10 for 1GB, $20 for 2GB, $30 for 3GB and so on. That’s it. With no annual contract required.

It’s hard to predict your data usage when it changes month to month. One month you’re streaming live sports, the next you’re mostly just checking email. At the end of each month, you’ll get your unused data credited in dollars and cents, so you only pay for what you use.
