About the Networks AT&T Coverage AT&T Coverage Map Coverage in Your Area AT&T Plans

AT&T’s advertising says that they are the carrier with the ‘most’ coverage and ‘strongest’ network…yet the competition between carriers to be the best network is fierce. Unfortunately, three out of four networks all claim to be the best. Where does AT&T fit? We reveal the answer in this guide to AT&T’s coverage.

AT&T’s wireless coverage is very solid—it has to be. Along with Verizon, AT&T has millions of premium business customers, and these premium customers would not suffer a sub-par network. Notably, AT&T’s 3G coverage is the widest of all carriers, but their 4G LTE footprint is not as wide as either Verizon’s or T-Mobile’s.

Three carriers all claim to have the best network. AT&T HAs the Widest 3G Network in THE LOWER 48 STATES

AT&T uses the words “strongest” and “best” in their advertising.

The question is…is the AT&T network the best, the strongest, the largest?

There are many answers to this question, depending on where you look for help and in backing up their claims AT&T only use one source. T-Mobile consistently claims that their speeds are fastest based on user data and Verizon has been awarded best network titles from the industry’s most authoritative testing service, RootMetrics.

In fact, the AT&T network has dropped a spot to position #2 in terms of 4G LTE area covered in the lower 48 states.

AT&T sit comfortably at either position 2 or position 3, depending on the test or the comparison point. However, if you’re mind is already made up you want to get a new AT&T plan, you can compare their latest plans here or their latest deals here

US National Wireless Networks

There are four major cell phone networks in the United States, powering over 30 different carriers. These major networks are:

Many smaller carriers also use one of these four networks to offer their services. These smaller carriers (called MVNOs — essentially a mobile carrier using another carrier’s network) can offer you AT&T coverage at a cheaper price. We’ve listed those MVNOs below, or check out this page for the full list of carriers which operate on the AT&T network.

Our comparison information is based on the coverage maps provided by the networks on their own coverage pages.

There are over 30 carriers in the US but only 4 national wireless networks. Smaller carriers effectively rent space from the big networks.

Based on the coverage maps supplied by all carriers on their websites and analysis of the areas covered, AT&T’s coverage is the second best in terms of pure geographical area covered for 4G LTE. 

AT&T Coverage Compared

AT&T’s 3G Network has the largest geographical coverage in the US at 70% based on the analysis of their coverage map and miles covered.

There are two main connection types used by AT&T— 4G LTE and 3G HSPA.

When it comes to 4G LTE, Verizon’s national 4G network beats out AT&T’s by just 2%; however, AT&T has the most 3G coverage area of any carrier in the US.

In terms of 4G LTE, Verizon’s coverage is wider and AT&T and T-Mobile are relatively neck and neck and are within 6% of each other. T-Mobile’s newly added 600 MHz network is responsible for the tighter competition and growth in coverage footprint over the past few years.

Based on the Carrier’s own coverage maps, the following geographical coverage areas have been measured.

Lower 48 states as per carrier’s own coverage maps

  • Verizon: 70% 4G coverage
  • AT&T: 68% 4G coverage
  • T-Mobile: 62% 4G coverage
  • Sprint: 30% 4G coverage

While AT&T ‘s 4G network is second-widest in terms of coverage area, the carrier’s 3G network is superior to all the others in terms of area covered. Although 3G coverage isn’t the fastest, it is the network type that your phone will drop back to in the absence of a 4G signal. Accordingly, AT&T offers equal service to Verizon in terms of square miles covered with 70% of the country covered.

AT&T’s Coverage Map Compared

The interactive map below shows you exactly how much of the country AT&T covers. Combined, the carrier’s 3G and 4G networks span much of the United States. That said, AT&T does have a few dead zones. Parts of Montana, Arizona, Wyoming, and a few other western areas aren’t 100% covered. AT&T has roaming agreements with local networks in those areas.

The coverage map shows the AT&T coverage in square miles across the lower 48 states and does not match the advertising claims of 99% coverage. However, the key to these coverage claims is that 99% of the population and where the population resides is covered, not 99% of the country.

When a network advertises 99% coverage, it refers to homes covered and not geography

All carriers tend to refer to their coverage in ‘pops’ which means population covered.

What the Awards Say

The data used in this article is based on the coverage actually reported by carriers on their own coverage maps and the geographical areas covered. We’ve measured and mapped all of the coverage mathematically, based on mapping software. In terms of quality, there is no universal answer as to the quality of the network as this is subjective. Some user-based studies are used as the benchmarks in advertising claims, whereas other testing services use drive tests where coverage is tested by phones as cars drive through an area. In terms of real-life user experience, the most important thing is the phone used as that the most modern phones before much faster with more antennas and wireless network specs than older phones. Here’s what the other reports say.


Ookla runs a speed test app where users can run a speed test from their phones. In the Ookla Q1-Q2 speed test they measured over 4.1 million unique mobile devices in over 11.5 million sessions. They found that AT&T has the fastest download speeds followed by T-Mobile, Verizon, and lastly, Sprint.
