Google Fi Wireless has launched a new Super Network that automatically switches phones between two 5G networks in real time, bringing back the multi-network switching that made the service famous when it launched as Project Fi.

Google announced the feature on Tuesday, 10 November 2026, saying it is rolling out from today on Pixel 9 and newer phones with Google Fi active. The company says the Super Network gives subscribers the fastest speeds and most expansive coverage in the United States, combining two of America’s best 5G networks with millions of premium Wi-Fi networks in a single plan.

Two 5G networks on one eSIM

The switching uses Android’s Multiple Enabled Profiles technology, which runs two carrier profiles on a single eSIM chip. If the primary connection weakens, the phone moves to the secondary data connection before the signal drops, so users hit fewer dead zones on highways, country roads and other places where one network alone struggles.

Google has not named the second network operator. Its frequently asked questions list T-Mobile as the primary network partner, and reports say the second partner is not being disclosed at launch. There is no manual switching at first: the phone decides when a change will meaningfully improve performance, using what Google calls smart thresholds.

Google says subscribers keep top priority on the primary network, so data is never deprioritised there, and the backup network carries high priority too, leaving subscribers among the last to be slowed when a network is congested. Wider device support is expected in 2027.

Wi-Fi Auto Connect+ for crowded places

Alongside the cellular switching, Google is expanding Wi-Fi Auto Connect+, which connects phones automatically to high-quality Wi-Fi in millions of locations, including airports, malls, stores and restaurants, without the user opening settings or logging in. Google says the connections are encrypted automatically through its Fi Virtual Carrier Network.

Wi-Fi Auto Connect+ is available on Pixel devices and is rolling out to select Samsung and Motorola phones, including Samsung Galaxy models running One UI 9 and above. Both new features are included at no extra cost on Google Fi’s Unlimited Premium and Flexible plans.

It works abroad too

Network switching and Wi-Fi Auto Connect+ also work internationally, so travel and messaging apps stay connected when subscribers land abroad, subject to the usual international data limits on each plan. Google is also adding Ask Fi, a support agent powered by Google AI inside the Fi app, to help with connectivity troubleshooting and billing questions.

For new subscribers, Google is offering 500 dollars off a Pixel 11 Pro instantly, plus 599 dollars back over 24 monthly credits and a 10-dollar monthly service credit for two years on the Unlimited Premium plan, with that offer ending on 18 November 2026. Existing Pixel owners who switch to Google Fi can get 50 percent off select unlimited plans for 12 months, ending on 1 December 2026.
