Google Fi Coverage Map

What network does Google Fi use?

Google Fi uses the T-Mobile network to provide coverage.

Since Google Fi relies on T-Mobile, its coverage is the same as that of T-Mobile.

You may have heard or read about Google Fi using other networks for coverage. That is because previously, Google Fi used to use T-Mobile, Sprint, and US Cellular to provide service. 

However, since the Sprint-T-Mobile merger, Sprint and T-Mobile have become one network.

Google Fi also stopped using US Cellular for coverage as of February 28th, 2023.

The only network Google Fi uses for coverage right now is the T-Mobile network.

Google Fi 5G Coverage

Google Fi rides on T-Mobile’s 5G network, which covers 36.0% of the U.S. land area and 98% of the U.S. population.

T-Mobile's 5G network is made up of its low-band 5G network, called Extended Range 5G, and its mid-band and mmWave 5G network, called Ultra Capacity 5G.

T-Mobile Extended Range 5G covers 325 million people.

T-Mobile Ultra Capacity 5G covers 275 million people.

T-Mobile, and as a result Google Fi, has the second largest 5G network in the country.

T-Mobile's 5G network is also the fastest in the country, with median download speeds of 248.1 Mbps.

Google Fi 4G LTE Coverage

Google Fi offers nationwide 4G LTE coverage using T-Mobile’s 4G LTE network, which covers over 99% of Americans.

Google Fi Data Speeds by State

Data speeds play an important role in shaping what kind of experience you have using a cellular network.

How fast are Google Fi's data speeds?

We crunched the numbers on our crowd-sourced speed test data to find out. We learned Google Fi had median download speeds ranging from 13 Mbps in Alaska and going up to an impressive 371 Mbps in the Washington, DC. Median upload speeds on Google Fi were between 5.5 Mbps in Mississippi and went up to 47.2 Mbps in Idaho. And median latency was between 22 ms and 184 ms.

Google Fi vs. T-Mobile Coverage

Google Fi has the same coverage as T-Mobile because it uses T-Mobile towers for service.

Google Fi customers will get the same access to T-Mobile's 4G LTE and 5G networks as T-Mobile customers directly.

Domestic roaming is even available on Google Fi, which means Google has partnered with smaller carriers in certain areas of the United States to provide additional coverage where T-Mobile does not have service.

Google Fi vs. AT&T Coverage

Google Fi coverage is worse than AT&T coverage.

Google Fi only covers 46.6% of the U.S., while AT&T has the largest coverage footprint in the country right now with 78.1% coverage:

Google Fi also has less 5G coverage than AT&T does.

Google Fi covers 36.0% of the U.S. with 5G. AT&T covers 43.3% with 5G:

Along with coverage, data speeds are another important factor to consider.

Google Fi has about 2.5x faster download speeds than AT&T.

Our crowd-sourced data shows Google Fi's median download speed is 152.3 Mbps, while AT&T's median download speed is just 61.2 Mbps. Similarly, Google Fi's median upload speed is 17.3 Mbps, compared to AT&T's 11.3 Mbps.

For users who want fast data speeds for video streaming, downloading, and uploading content, Google Fi may be a better option. 

Overall, AT&T offers more extensive coverage than Google Fi. 

You’re more likely to have AT&T signal in more places, which can make AT&T a better choice for more rural areas. 

However, Google Fi provides faster download speeds than AT&T, which may make it a great choice for crowded cities or other environments with a lot of people.

Google Fi vs. Verizon Coverage

Google Fi’s overall coverage is worse than Verizon’s coverage.

Verizon covers a whopping 67.4% of the area in the US, compared to only 46.6% covered by Google Fi:

That said, Google Fi has substantially more 5G coverage than Verizon does.

Google Fi covers 36.0% of the U.S. and over 325 million people with its 5G network.

Meanwhile, Verizon has just 14.5% 5G coverage and reaches 230 million people with its 5G network.

Having an expansive 5G network helps Google Fi get faster speeds than Verizon.

From our crowd-sourced data, Verizon's median download speed across the country are 61.2 Mbps.

Google Fi's median download speeds are an impressive 152.3 Mbps.

Google Fi also has faster upload performance. Median upload speeds on Google Fi are 17.3 Mbps, while median upload speed on Verizon are 11. 7 Mbps.

Both carriers will likely perform well in cities, but you can definitely expect faster speeds on Google Fi.

Outside of cities, Verizon’s greater overall coverage area may come in handy.
