Google has announced a “super network” upgrade for its Fi mobile service, adding a second 5G carrier to the platform. The move means that U.S. Fi customers will again be able to switch between two 5G networks to keep the strongest signal, but the company has not revealed which network will join T‑Mobile.
Fi launched in 2015 under the name Project Fi, originally supporting both T‑Mobile and Sprint. Early versions only worked on Google’s Nexus phones and automatically hopped between the two carriers based on signal strength. When T‑Mobile acquired Sprint in 2020, Fi became a single‑network service in the United States, although it still switched between carriers when users travelled abroad.
With the new super network, Google says the service will “hop between T‑Mobile 5G and a different 5G network to provide the best possible connectivity.” The company’s blog post highlights that the two networks are “two of America’s best 5G cellular networks,” but it does not disclose the second carrier’s identity.
By returning to a dual‑carrier model, Fi aims to improve coverage and performance for its users. The upgrade is part of Google’s ongoing effort to keep its mobile offering competitive in a market dominated by large carriers.
