Google Fi Super Network Switches Pixels Between Two 5G Carriers
Pixel 9 and newer phones on Fi now jump to a second 5G network when the signal drops, at no extra cost. Here is who gets it and what the 2x Wi-Fi claim means.

The new Google Fi super network, announced on November 10, 2026, automatically moves Pixel 9 and newer phones between two US 5G networks when the main signal weakens. It is rolling out now at no extra cost, and it brings back the multi-network switching that made Project Fi famous, which Fi dropped in 2023.
Alongside it, Google is widening Wi-Fi Auto Connect+, a feature that quietly hops your phone onto encrypted public Wi-Fi in airports and malls, to select Samsung and Motorola phones. In short, Fi is trying to fix the two places where phones struggle most: empty highways and crowded buildings.
What Is the Google Fi Super Network?
The Google Fi super network is a single Fi plan that can use two cellular networks instead of one. Most of the time your phone stays on what Google calls the Primary network. When that connection drops or slows down, Fi switches you to a Secondary network in real time, without you touching a setting.
In its announcement, Mauria Finley, VP of Google Store and Google Fi, called it "our greatest innovation in connectivity yet" and said that, unlike other major carriers, only Fi switches between networks automatically. Google does not name the second carrier. Engadget guessed one of the two is probably T-Mobile, based on past partnerships, but that is speculation.
How Does the Network Switching Work?
The trick is an Android eSIM technology called Multiple Enabled Profiles (MEP), which lets one eSIM chip hold two carrier profiles at the same time. According to 9to5Google, Fi uses "smart thresholds" so it only switches when the move meaningfully improves performance, and there is no manual switch at launch.
Google also says your data is never deprioritized on the Primary network, while the backup network gives Fi users "highest QCI priority," meaning they are among the last to be slowed down in congestion. A new "Your super network" card in the Fi app shows which network you are on, and a "See activity" view lists your recent switches.
What About Wi-Fi Auto Connect+?
Wi-Fi Auto Connect+ handles the indoor problem. It connects your phone to vetted Wi-Fi in airports, malls, stores and restaurants with no login page. Fi encrypts that traffic automatically through its Virtual Carrier Network, so you are not left exposed on an open hotspot. If you want the basics of how that kind of protection works, our end-to-end encryption explainer covers the idea.
Google defines "faster" here as 2x better reliability and 30% lower latency than nearby Fi cellular networks. The feature works in select locations across North America, Europe, Asia and Brazil on Pixel 5a and newer, and it is rolling out to Samsung phones on One UI 9 or higher and select recent Motorola models.
| Feature | Phones | Where | Cost |
|---|---|---|---|
| 5G network switching (US) | Pixel 9 and newer, Fi on eSIM only | United States | Included in every Fi plan |
| Network switching abroad | Pixel 7 and newer | Partner networks abroad | Unlimited Premium and Flexible plans |
| Wi-Fi Auto Connect+ | Pixel 5a and newer, select Samsung and Motorola | North America, Europe, Asia, Brazil | No extra cost |
Who Gets It, and What Is the Catch?
The catch is hardware. US network switching needs a Pixel 9 or newer with Fi active on eSIM and any other SIM turned off, so dual-SIM users and owners of older Pixels are left out for now. Google also warns that 5G and switching are not available everywhere and that results depend on your device, signal and battery.
Fi is adding an AI support agent called Ask Fi in the app for billing and troubleshooting questions, and Engadget reports that human support stays available. Launch offers include a free Pixel 11 Pro for new subscribers, made up of a $500 instant rebate and $599 in credits over 24 months, until November 18. Fi already leaned on software tricks before, as our report on AI-improved Fi call quality showed.
What Should You Check Before Switching?
- Your phone: Pixel 9 or newer for US switching, Pixel 5a or newer for Wi-Fi Auto Connect+.
- Your SIM setup: Fi must run on eSIM with no other active SIM.
- Your plan: international switching needs Unlimited Premium or Flexible.
- Your routes: the benefit is biggest on highways and rural roads with patchy coverage.
Our Take
Try the relative test. If you drive through spotty rural coverage or travel abroad often, a second network that takes over on its own is a real upgrade, the same "fill the gaps" logic behind satellite-to-phone plans. If you spend most of the day on home Wi-Fi in a city, you will barely notice it. Until Google names the second carrier, coverage maps will be hard to compare.
