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

Google Fi is reintroducing a feature that allows users to switch between two 5G networks, depending on which one offers better connectivity. This is only available for Pixel 9 and newer phones that have Google Fi active on an eSIM, with any non-Fi SIMs disabled.

In 2015, Google Fi initially offered network switching between T-Mobile and Sprint networks. However, the two networks merged in 2020 when T-Mobile acquired Sprint, resulting in the discontinuation of network swapping.

Former Google Fi Wireless senior product manager Jane Harnett explained that the company discontinued the feature because the "wireless landscape consolidated via mergers and limited our ability to offer multiple networks within the US." Despite this, network switching remains available internationally.

Now, Google Fi is bringing back this feature in the US, enabling users to hop between two networks. According to Harnett, the new network switching is faster than before and utilizes eSIMs' ability to connect to multiple carriers simultaneously. Previously, Fi's switching was single-SIM, which meant the phone had to wait for service to drop completely before performing a slow SIM profile swap to another network.

The new system on newer Pixel devices keeps two eSIM network profiles on standby at the same time, using MEP technology. The Android OS monitors live connection quality and allows the phone to transition seamlessly to a better connection with minimal battery impact.
