Google Fi Launches 2-Network 5G Switching on Pixel 9 as US Coverage Feature Returns

Q: Which mystery telecom carrier secretly teamed up with Google Fi to revive its famous multi-network switching?

Google has not publicly identified the second carrier, so the mystery partner remains officially undisclosed. What is known is that Google Fi’s new “super network” switches between T-Mobile and one other 5G network on eligible Pixel 9-and-newer phones using eSIM. Google confirmed only that the service uses “two of America’s best 5G cellular networks,” while Fi’s own coverage materials continue to name T-Mobile as its primary network. That leaves Verizon or AT&T as the likely possibilities. Among outside reports and coverage-map comparisons, Verizon is the more common guess, partly because Google says the backup network supports Ultra Wideband and because some analysts say Fi’s expanded coverage footprint looks closer to Verizon’s than AT&T’s. But Google has not verified that, and no carrier has been officially named. So the most accurate answer is that no one outside the companies can say for certain yet. T-Mobile is confirmed; the second partner is still secret, with Verizon widely suspected but unconfirmed.

Starting today, Google Fi is rolling out its “super network” on Pixel 9 and newer phones, letting eligible devices switch automatically between two 5G networks for stronger connectivity.
The feature works only when Fi is active on eSIM and any non-Fi SIMs are disabled, using dual eSIM profiles and Android monitoring to move to a better network before service drops.
Google says the new system switches faster than its earlier setup, which relied on single-SIM or physical-SIM-plus-eSIM handoffs that were slower and less certain.
The capability revives a US feature Fi lost after T-Mobile acquired Sprint in 2020; Google declined to name the second network, while its FAQ still lists T-Mobile coverage.
