Overview
- Google Fi began rolling out the feature Tuesday for Pixel 9 and newer phones, enabling real-time automatic switching between two 5G networks when signal quality drops.
- The switch is powered by Multiple Enabled Profiles (MEP) eSIM technology that lets a single physical eSIM host two active carrier profiles at once.
- T‑Mobile is confirmed as Google Fi’s primary host carrier and the backup is described only as a unnamed “major carrier” with more than one million U.S. customers.
- The update also adds Wi‑Fi Auto‑Connect+, which automatically links phones to vetted public Wi‑Fi networks without manual logins to reduce buffering in crowded places.
- This revival echoes Project Fi’s original multi‑network approach from 2015 and restores failover that was dropped in 2023 while Google Fi says the features will work internationally.
