Google Fi now switches between the best mobile networks automatically – how it works

Google Fi, a mobile and Wi-Fi service, has introduced two new features that automatically optimize users' connections on their Pixel phones. These enhancements are designed to provide faster and more reliable service without requiring any additional configuration from the user. The first feature is a mobile connection upgrade that automatically switches between the two largest 5G cellular networks in the United States.

This ensures that users always have access to the fastest and most stable connection available. The second feature, Wi-Fi Auto Connect+, automatically connects to premium Wi-Fi networks in over a million locations, such as airports and malls. This maintains a reliable connection even when cellular service is weak. Both features rely on a technology called MEP (Multiple Enabled Profiles) that allows a single eSIM chip to manage multiple SIM profiles simultaneously.

Users need to disable any non-Fi SIMs for these features to work. While Google has not disclosed the specific 5G networks that will be used, it is likely that they will be among T-Mobile, AT&T, or Verizon. The service will be available internationally and included in Google Fi's Unlimited Premium and Flexible plans without any extra charge.
