In today's mobile world, fast and reliable connectivity is almost second nature. But even in places like the U.S., where mobile connections are nearly ubiquitous, there are still times when you turn to your phone for that split-second answer and don't have fast enough speed. Or you can't get calls and texts because you left your phone in a taxi (or it got lost in a couch cushion for the day). As mobile devices continually improve how you connect to people and information, it's important that wireless connectivity and communication keep pace and be fast everywhere, easy to use, and accessible to everyone.
That's why today we’re introducing Project Fi, a program to explore this opportunity by introducing new ideas through a fast and easy wireless experience. Similar to our Nexus hardware program, Project Fi enables us to work in close partnership with leading carriers, hardware makers, and all of you to push the boundaries of what's possible. By designing across hardware, software and connectivity, we can more fully explore new ways for people to connect and communicate. Two of the top mobile networks in the U.S.—Sprint and T-Mobile—are partnering with us to launch Project Fi and now you can be part of the project too.
Our three focus areas include:
Helping you get the highest-quality connection
Project Fi aims to put you on the best network wherever you go. As you move around, the best network for you might be a Wi-Fi hotspot or a specific 4G LTE network. We developed new technology that gives you better coverage by intelligently connecting you to the fastest available network at your location whether it's Wi-Fi or one of our two partner LTE networks. As you go about your day, Project Fi automatically connects you to more than a million free, open Wi-Fi hotspots we've verified as fast and reliable. Once you're connected, we help secure your data through encryption. When you're not on Wi-Fi, we move you between whichever of our partner networks is delivering the fastest speed, so you get 4G LTE in more places. Learn more about our network of networks.
Enabling easy communication across networks and devices
Project Fi works to get technology out of the way so you can communicate through whichever network type and device you're using. Wherever you're connected to Wi-Fi—whether that's at home, your favorite coffee shop or your Batcave—you can talk and text like you normally do. If you leave an area of Wi-Fi coverage, your call will seamlessly transition from Wi-Fi to cell networks so your conversation doesn’t skip a beat. We also want to help phone numbers adapt to a multi-screen world. With Project Fi, your phone number lives in the cloud, so you can talk and text with your number on just about any phone, tablet or laptop. So the next time you misplace your phone, you can stay connected using another screen. Check out how it works.
Making the service experience as simple as possible
Project Fi takes a fresh approach to how you pay for wireless, manage your service, and get in touch when you need help. We offer one simple plan at one price with 24/7 support. Here's how it works: for $20 a month you get all the basics (talk, text, Wi-Fi tethering, and international coverage in 120+ countries), and then it's a flat $10 per GB for cellular data while in the U.S. and abroad. 1GB is $10/month, 2GB is $20/month, 3GB is $30/month, and so on. Since it's hard to predict your data usage, you'll get credit for the full value of your unused data. Let's say you go with 3GB for $30 and only use 1.4GB one month. You'll get $16 back, so you only pay for what you use. Get all the details about our plan.
Be part of the project from the start
We're beginning Project Fi's Early Access Program to invite people to sign up for the service. Project Fi will be available on the Nexus 6, which we developed with Motorola and is the first smartphone that supports the hardware and software to work with our service. If you live
where we have coverage in the U.S., request an invite at
fi.google.com to get started.
How it works
One number to chat across networks and devices
Calls and texts over Wi-Fi for more coverage
Wherever you're on Wi-Fi—whether in your home, your favorite coffee shop or your Batcave—you can talk and text like you normally do.
Calls transition seamlessly between Wi-Fi and cell networks
If you start a call over Wi-Fi and walk outside, Project Fi detects when your signal becomes weak and seamlessly moves your call over to a cell network to keep the conversation going.
Use your phone number with tablets and laptops too
Talk, text, and check voicemail on the screen nearest you
Connect any device that supports Google Hangouts (Android, iOS, Windows, Mac, or Chromebook) to your number. Then, talk and text with anyone—it doesn't matter what device they're using.
