What is Google Fi’s new super network — and how do I turn it on?

Google Fi’s new super network, rolling out from November 10, 2026 at no extra cost on any Fi plan, automatically switches eligible phones between two of America’s top 5G networks using Android’s Multiple Enabled Profiles (MEP) technology. US switching needs a Pixel 9 or newer with Fi active on eSIM and any other SIM disabled.

You are driving through a dead zone on a country road and your call drops right in the middle of directions. Short answer: Google Fi’s new super network, rolling out starting November 10, 2026 at no extra cost on any Fi plan, automatically switches eligible phones between two of America’s top 5G networks so you stay connected when one network weakens.Why it matters: it uses Android’s Multiple Enabled Profiles (MEP) technology, which lets one eSIM chip run two carrier profiles at the same time. The phone stays on a Primary network and moves to a Secondary network in real time only when that meaningfully improves performance — there is no manual switch at launch, and Google has not named the second carrier.

The Fi app gains a ‘Your super network’ card showing which network you are on and a ‘See activity’ view of past switches, and a companion feature, Wi-Fi Auto Connect+, joins vetted Wi-Fi in places like airports and malls automatically with encryption, and works on more phones.1. Check your phone: US network switching needs a Pixel 9 or newer. Pixel 8 and older do not get switching.2.

Make Fi your eSIM: Fi must be active on eSIM for switching to work.3. Turn off any other SIM: any non-Fi physical SIM or eSIM must be disabled — dual-SIM users have to choose.4. Update the Google Fi app and look for the ‘Your super network’ card on the Home tab to confirm it has rolled out to you — rollout is gradual.5.

Leave it alone once it is on: switching is automatic, so do not hunt for a manual toggle that does not exist yet.Pro tip: if you rely on a second line for work or travel, think before you disable it — that is the real tradeoff of this feature, not the price, since switching is included free.Ad’s take: this is the old Project Fi trick I always liked — let the phone find the better signal so you don’t have to. If it cuts even a few dead-zone drops on a drive, that’s a win in my book.
