How does this work?In most areas, multiple cellular networks are available — in fact, the majority of Project Fi usage occurs in areas where more than one of our partners offers LTE coverage. But factors like obstructions from nearby buildings can meaningfully impact the speed and coverage available from each LTE connection. By analyzing speeds from each network, Project Fi is able to predict the fastest network at your location — down to the city block — and automatically connect you. We’re constantly adapting to consider how factors like new cell towers and newly-available radio frequencies are impacting real-world speeds.Part of Project Fi’s promise is to ensure you have connection when you need it, even in areas with poor speeds or limited coverage. Your Fi device recognizes when your connection is weak and adjusts in real time. By accessing multiple cellular networks, Fi users have a connection nearly 99% of the time, and spend about 95% of cellular time on LTE — which will improve even further with the addition of U.S. Cellular.

U.S. Cellular coverage will be automatically rolling out to all users over the coming weeks. We’re excited to add our third partner and hope you’ll join us, too.
