Google Fi Speed Test FAQ
How fast is Google Fi?
Google Fi speeds reach up to 300 Mbps on 5G networks, with typical 4G LTE speeds ranging from 20 to 75 Mbps. Performance varies based on location, network congestion, and whether you connect to T-Mobile or US Cellular towers. Google Fi automatically selects the strongest available network. After exceeding premium data thresholds (35 GB on Simply Unlimited, 50 GB on Unlimited Plus), speeds may be reduced. Run a speed test to check your real-world Google Fi performance.
What networks does Google Fi use?
Google Fi operates on T-Mobile and US Cellular networks, automatically switching between carriers to provide the best signal and speed. This multi-network approach provides broader coverage than using a single carrier. On supported Pixel and Samsung phones, Google Fi can seamlessly switch between networks during use. On other compatible phones, Google Fi uses only the T-Mobile network. Wi-Fi calling is also supported, allowing calls and texts over any WiFi connection.
Does Google Fi work internationally?
Yes, Google Fi offers international coverage in over 200 countries and territories at no extra charge on unlimited plans. Data is available at the same rate as domestic usage on the Flexible plan ($10 per GB). Unlimited plan users get high-speed data abroad, though speeds may be limited to 256 Kbps in some countries. International calling rates vary by destination. This makes Google Fi one of the most travel-friendly mobile carriers in the United States.
How do I test my Google Fi speed?
Use the speed test tool on this page to measure your Google Fi download speed, upload speed, and ping latency. For accurate results, close background apps and ensure you are testing over cellular data rather than WiFi. Google Fi speeds depend on which network (T-Mobile or US Cellular) your phone connects to and your plan's data priority tier. The test takes approximately 30 seconds and works on any device with an active Google Fi connection.
