Frequently Asked Questions

What is an MVNO?

An MVNO (mobile virtual network operator) sells mobile service without owning cellular infrastructure. MVNOs like Google Fi lease access to major carrier networks in the United States and deliver coverage using those host networks.

Which networks power Google Fi?

Google Fi uses T-Mobile for coverage in the United States.

How does Google Fi coverage compare to major carriers?

MVNO coverage mirrors the host networks it uses. Compare the host carrier performance above to see how those networks perform in the United States.

How can I check coverage in my area?

Use the coverage maps above to explore real-time coverage by host network. Each map reflects the underlying carrier used by Google Fi.

What do the performance metrics mean?

The performance metrics summarize median download speed, upload speed, and latency from crowdsourced tests on the host networks listed above. Higher download/upload and lower latency indicate a faster, more responsive connection.

Why can parts of the coverage map look empty?

Coverage maps are built from crowdsourced tests, so areas with limited recent data can look incomplete. Coverage improves as more tests are collected.

How can I contribute coverage data for the United States?

Download the CoverageMap app and run a few speed tests with location enabled. Your results help improve coverage accuracy and unlock local rankings faster.
