In order to enable the functionality, you have to be running Android 7.1.1 (or newer). So, how does Instant Tethering work? If your Pixel or Nexus smartphone has an active cellular connection, any supported device (that is logged into the same
Google account) can automatically connect to the host's Wi-Fi hotspot.
"When you unlock a tablet such as the Pixel C, it will notice if there is no internet connection available, and will ask your Pixel phone if it has internet and battery life," writes Google Pixel Product Manager Omri Amarilio. "If it does, we will give you an option to enable a secure hotspot and pair automagically, without even taking your phone out of your pocket."
Google has made this process as seamless as possible, and will keep you connected as long as your smartphone has enough battery life and as long as you are actively using the internet. Google also notes that if you are connected using Instant Tethering and remain idle for 10 minutes, you will automatically be disconnected to preserve battery life.
It appears that Instant Tethering is currently only supported on tablets, and doesn't [yet] extend to notebooks. It should be noted that Apple has supported similar functionality with the iPhone and an
iPad or
macOS computer using
Continuity and Instant Hotspot since
iOS 8.0.
