When you use Google Fi’s Virtual Private Network (VPN) on a cellular or Wi-FI network, your internet traffic is encrypted and protected. Encrypted data takes up a little more space and uses about 10% more data.
When your Wi-Fi connection is unusable, your phone will start using mobile data. If you're in the middle of a download, it might keep downloading over mobile data. To go back to Wi-Fi, try moving closer to your router or access point, or pick a different network.
To turn on the Google Fi VPN:
- Open the Google Fi app.
- Go to "Phone Settings" and tap Fi Network Tools.
- Turn on Enhance network. You're connected when the status bar shows .
Google Fi VPN won't handle this information:
- Traffic over your local network, such as your device's connection to your smart home devices, is not handled by the VPN.
- Your tethered devices.
- Anything you do while your phone is in Airplane mode.
- Information handled through apps that bypass VPNs.
- Some Google services traffic, such as Android notifications to your device.
- Your work profile. VPN is only active for your primary profile.
- Custom DNS lookups are not currently supported. This includes both external and local DNS lookups, such as Google Wi-Fi's On.Here functionality.
