Google Fiis often marketed as if it were created entirely by Google. Pixel devices are featured prominently on the Fi website, and the company downplays mentions of partners likeMotorolaandSamsung. While they’re not completely marginalized, Google knows where its bread is buttered.
This attitude extends to the network Fi operates on. That’s right – Google hasn’t paid to put up any cellphone towers of its own. So, how does it actually function? Here’s what you need to know about Fi’s infrastructure.
What is an MVNO and how is it different from a regular carrier?
You’ve probably been exposed to all kinds of MVNOs without even knowing.
Which carrier network does Google Fi use domestically?
You might be familiar with the network giant
In the US, Google Fi operates primarily on the T-Mobile network. By extension, that includes towers absorbed during T-Mobile’s merger with Sprint. Fi supports 5G if you’re in acovered areawith a compatible phone, but it does fall back to 4G if that criterion isn’t met. Like all major American carriers, T-Mobile has retired 3G.
I say “primarily” because Fi also relies on something dubbed the W+ network. It’s something exclusive to Pixel owners withAndroid 12or later and Fi VPN functions enabled, but it works around data congestion by tunneling through compatible Wi-Fi hotspots. Even if you have a Pixel, though, you’re unlikely to see “W+” pop up in your phone’s status bar – the tech is limited mostly to “certain airports, malls and stadiums,” as Google puts it.
Fi also supports conventional Wi-Fi calling if you need it.
Plus, it’s important to note that traffic over W+ counts towards your monthly bill, so you may want to turn to public hotspots if you’re trying to make a call and/or you’re not too worried about security. Indeed, Fi also supports conventional Wi-Fi calling if you need it.
How to set up an eSIM on Google Fi
Setting up a Google Fi connection on a new phone is basically as simple as downloading an app.
Which carrier network does Google Fi use internationally?
More flexibility when you need it
There’s no formal list of them, but Google says that Fi services are available in over 200 countries and territories. It also notes that the service can and will switch networks automatically as needed, all of which is standard for the international roaming plans offered by US carriers.
You do have to buy one of the phones featured on the Fi website to guarantee access.
Something less common is that people on Google’s Flexible and Unlimited Plus plans get international coverage at no extra cost. You do, however, have to buy one of the phones featured on the Fi website to guarantee access, and only some Pixel and Samsung devices can tap 5G abroad.

Why doesn’t Google build its own network?
It appears to have the means
The major reason is cost, naturally. While Google’s parent company Alphabet is worth about $2 trillion, a network covering the continental US would cost billions of dollars to launch, never mind Alaska, Hawaii, and international roaming on top of it. Google would also have to pay to maintain, expand, and upgrade its infrastructure consistently, something it’s already reluctant to do with Google Fiber internet access. The company saves a lot of money and grief by just paying T-Mobile.

There might also be antitrust concerns. A first-party network would create the possibility of an ecosystem operated entirely by the company, i.e. Google phones running Google software that connects to Google towers for a Google phone service. A US district court has already ruled thatGoogle has a monopoly over search. On top of that, carrier partners might get upset, which could risk Pixel devices being excluded from some stores and markets.
We’ll probably never see Fi become the self-contained entity Google likes to depict in its sales pitch.
About the only benefit to a proprietary network would be control. Even then, Google would have to operate within Federal Communications Commission guidelines such as net neutrality, so it couldn’t unfairly favor its own products and services. Hypothetically, you could see Fi expand or switch to AT&T and/or Verizon – but, we’ll probably never see Fi become the self-contained entity Google likes to depict in its sales pitch – it just doesn’t make any business sense.
