Google is extending the Project Fi VPN to all your connections, so you’ll now have more security and privacy wherever you use data.
The enhanced network also enables a fast connection by intelligently switching between Wi-Fi and cellular.
When you enable Google's new enhanced network, all of your mobile and Wi-Fi traffic will be encrypted and sent through Google's virtual private network (VPN) on every network you connect to, so you’ll have the peace of mind of knowing that others can’t see your online activity. That includes Google- Google says its VPN is designed so that your traffic isn’t tied to your Google account or phone number.
Google's enhanced network automatically detects when your Wi-Fi connection becomes unusable and then fills in those connection gaps with cellular data. With the enhanced network, Google says htat you’ll have a seamless connection on the go, and that waiting to be reconnected becomes a thing of the past.
Google will begin rolling out the enhanced network later this week to Fi-compatible phones running Android P. You can enable it anytime in Fi Network Tools in the Project Fi app.
