Google Fi is bringing back multiple cell network support for better coverage

Google Fi is launching a new 'super network' that automatically switches users between two 5G networks, currently using T-Mobile's network in the US, for better connectivity. The feature is available on Pixel 9 and newer phones with Google Fi active on eSIM and non-Fi SIMs disabled. The feature was previously available when T-Mobile and Sprint's networks were separate, but stopped after T-Mobile acquired Sprint in 2020.
