Google Fi is introducing a new network switching feature that allows devices to automatically toggle between two 5G networks. The service aims to improve connectivity by selecting the provider with the strongest signal in real time.

The rollout begins today for users with Pixel 9 and newer models. To enable this functionality, the Google Fi account must be active on an eSIM, and all other non-Fi SIM cards must be disabled on the device.

This update marks the return of domestic network switching, a feature last available in 2015 when the service supported T-Mobile and Sprint. The company previously paused this capability following industry consolidation.

The new system uses MEP technology to maintain two eSIM profiles in standby mode simultaneously. The Android operating system monitors connection quality, allowing the device to switch networks before a signal drops.
