Google Fi Coverage Quick Stats

Here are fast facts about Google Fi's coverage:

  • Carrier: Google Fi
  • Network: T-Mobile
  • Total coverage: 46.6%
  • Total square miles covered: 1,551,924
  • 5G coverage: 36.0%
  • 5G square miles covered: 1,200,851

The above statistics come from our analysis of the FCC signal strength data for United States.

Google Fi Coverage

Google Fi is a mobile virtual network operator, or MVNO.

An MVNO is any cell phone carrier that does not operate its own cellular network.

Instead, MVNOs make agreements with mobile network operators, such as AT&T, T-Mobile, and Verizon, to use their existing cellular networks to provide coverage. In the case of Google Fi, it has an agreement with T-Mobile and uses T-Mobile's network to provide coverage.

Using T-Mobile's existing infrastructure allows Google Fi is to offer affordable plans without compromising on the quality of service. 

Google Fi gets full access to T-Mobile's three main networks:

  1. T-Mobile 4G LTE
  2. T-Mobile Extended Range 5G
  3. T-Mobile Ultra Capacity 5G

Here is a quick breakdown of each of these networks:

T-Mobile 4G LTE

T-Mobile's 4G LTE network is its largest network. It covers 46.6% of the U.S. and over 99% of Americans. Data speeds on T-Mobile 4G LTE are generally pretty good, but not as fast as speeds on 5G.

T-Mobile Extended Range 5G

T-Mobile's Extended Range 5G network covers 36.0% of the U.S. and over 325 million people by using low-band 5G frequencies.

Low-band 5G frequencies are known for traveling far distances.

Unfortunately, low-band 5G is not known to have the fastest speeds. Performance on T-Mobile's Extended Range 5G network will be similar to the performance on LTE.

T-Mobile Ultra Capacity 5G

T-Mobile's Ultra Capacity 5G network is by far its most exciting.

The Ultra Capacity 5G network uses mid-band and mmWave 5G frequencies to deliver speeds up to 3.3 Gbps.

As the name implies, 5G Ultra Capacity is built to handle a large volume of connected devices on the network at the same time and still deliver exceptional performance.

The mid-band and mmWave 5G frequencies travel in shorter wavelengths though, and this means they travel shorter distances than low-band 5G frequencies. As a result, Ultra Capacity 5G only covers 275 million people.

You can tell when you're connected to T-Mobile's Ultra Capacity 5G network on Google Fi because your phone will display a small "5G UC" icon in its status bar.

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 5G coverage map

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 LTE coverage map

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

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.

Use our T-Mobile coverage map to check T-Mobile's coverage footprint and data speeds in your area.

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.

Check our AT&T coverage map for a detailed look at AT&T coverage and data speeds in your area.

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.

Check our Verizon coverage map to see what Verizon's coverage footprint and data speeds look like in your area.
