Who Has the Best Cell Phone Coverage? AT&T vs. T-Mobile vs. Verizon

There are three major coverage networks in the U.S.: Verizon, AT&T, and T-Mobile. 

Not only are these three major networks operated by the major carriers themselves, but every sub-brand, or MVNO, runs on one or more of them. For example, when you sign up for Xfinity Mobile, you get your service via the Verizon network. 

As a result, it’s helpful to know how the three major networks stack up against each other, no matter which carrier you go with. In this article, we’ll explain which networks offer the best 4G and 5G coverage, and give you some important rules of thumb to keep in mind as you compare carriers.

4G vs 5G

You’ve probably heard or seen the words 4G and 5G at some point, whether you wanted to or not (coverage claims are a staple of carrier advertising, after all).

The “G” in 4G and 5G stands for “generation.” So, 5G is the fifth (and current) network generation, and 4G LTE is its predecessor. 

The innovations and upgrades that 5G provides over 4G are immense. They include faster upload and download speeds, lower latency, and better reliability. The fastest 5G speeds far exceed anything you’d be able to get from 4G. But 4G still has a place in the current equation.

Enhanced 5G Networks

Each carrier has its own version of “fast,” or enhanced 5G, but they use their own proprietary names to market them. These supercharged networks are speedy, but have smaller coverage areas. 

Verizon Ultra Wideband 5G

Verizon's Ultra Wideband 5G is its highest-performance version of 5G, designed to offer significantly faster speeds and lower latency than its Nationwide 5G. It uses millimeter-wave (mmWave) technology as well as C-band spectrum, which allows it to deliver fast download and upload speeds.

AT&T 5G+

AT&T's 5G+ is the branding used for its mmWave 5G network, which also offers ultra-fast speeds and low latency compared to its standard 5G network. AT&T uses "5G+" to differentiate this high-performance service from its regular 5G network, which is more widespread but offers lower speeds and greater coverage.

T-Mobile Ultra Capacity 5G

T-Mobile’s Ultra Capacity 5G (UC) is its high-speed offering, leveraging mid-band and millimeter-wave frequencies to deliver multi-gigabit speeds in select areas. Ultra Capacity 5G primarily serves metro areas and high-traffic locations, offering speeds up to 10 times faster than 4G LTE.

How the 3 Major Networks Compare: Coverage and Speed

The major carriers have historically been crafty about how they market their coverage in relation to their competitors. 

Every few months, for example, T-Mobile makes a big deal about being America’s coverage leader. However, they are prone to drawing their claims from crowdsourced data (we’re looking at you, OpenSignal) which tends to be less authoritative than other metrics. AT&T and Verizon do the same. 

So, you can’t trust entirely what the carriers are saying about their own networks. A much more reliable source—and the one we rely on for our own coverage statistics—is the FCC. 

That brings us to the following table, which lays out the national coverage percentages (i.e. what portion of the country is covered) for Verizon, AT&T, T-Mobile.

Verizon Coverage

Verizon leads the pack when it comes to nationwide 4G LTE coverage. This tends to be the signal your phone falls back to in rural areas, where 5G network reach is minimal. 

Things are different when it comes to Verizon’s 5G coverage—the carrier’s network, at present, trails competitors AT&T and T-Mobile in terms of overall reach. That said, where a Verizon 5G signal is present, you’re likely to enjoy some of the fastest speeds around thanks to the carrier’s rollout of its ultra-fast 5G UW. 

AT&T Coverage

AT&T offers almost as much 4G LTE coverage as Verizon, falling just 3% shy of the coverage leader in terms of the network’s overall reach. This makes going with AT&T a smart move if you’re looking for consistent cell phone coverage in rural and out-of-the-way places. 

T-Mobile Coverage

T-Mobile has historically trailed Verizon and AT&T with respect to the coverage reach of its 4G LTE network. While current stats are consistent with this trend—T-Mobile’s network covers 45% of the country, compared to 57% from AT&T and 60% from Verizon—that’s quickly changing, thanks to the company’s recent acquisition of USCellular. In other words, T-Mobile may soon overtake its competitors in 4G—if it hasn’t already.

T-Mobile’s 5G network, on the other hand, is without a doubt the most widespread in the country, a result of the company’s early investment in 5G infrastructure. T-Mobile’s 5G network currently covers 6% more of the country than its closest competitor AT&T.

Which Networks Do the MVNOs Run On?

Pretty much every cell phone carrier that’s not called Boost Mobile (they have their own network) makes use of either Verizon, AT&T, or T-Mobile’s coverage networks to provide service to their customers. 

So if, for example, you’re signing up for service with Cricket Wireless, you should check out the AT&T network beforehand, and make sure it’s present in the places you spend time (Cricket Wireless relies entirely on the AT&T network). Similarly, if you’re thinking about signing up with Mint Mobile, make sure to check out the T-Mobile network, since that’s the one the carrier runs on. Meanwhile, Spectrum and Xfinity provide their mobile services via the Verizon network.

The following is a list of MVNOs and the network, or networks, they operate on. 

How Signing Up With a Small Carrier Saves You Money

Sub-carriers tend to dispense with the bells and whistles of major carrier plans in the name of saving their customers money. 

For example, getting an unlimited data plan from Verizon might come packaged with streaming and international perks; an unlimited plan from Xfinity Mobile likely lacks these extra benefits. 

However, by signing up with Xfinity Mobile, you’ll mostly be able to enjoy the same coverage that regular Verizon customers get, at a small fraction of the price. 

One important caveat to that: as a rule, major carriers prioritize their own customers ahead of those on the sub-brands that also occupy the network, especially in times of network congestion. That can translate to occasionally slower speeds.  

Final Thoughts

With all of the cell phone carrier advertising noise coming at us at all times, it can be difficult to decipher the truth about which carriers offer the best coverage. We hope this article has clarified things for you, as well as adequately explained how going with smaller brands can give you access to major carrier coverage at a far lower price.
