Coverage in Arizona's Biggest Cities

Arizona is known for the breathtaking Grand Canyon, the mystical vibes of Sonoma, and its triple-digit temperatures. The Copper State is also home to reliable cell phone coverage from the Big Three of American telecom: AT&T, T-Mobile, and Verizon. AT&T has the largest network area, with a 4G LTE coverage map that reaches 64% of the state. T-Mobile operates the biggest 5G network, covering 29% of the map with its high-speed service. Verizon holds the number two spot for both 4G and 5G, covering 55% and 15% of the state map, respectively.

Whether you’re in one of the state’s large metro areas (like Phoenix or Tucson) or out in the remote stretches of the Sonoran Desert, this Arizona coverage guide will help you find the best coverage for your neck of the woods.

Verizon Coverage Map in Arizona

Verizon is number two in Arizona, with both the second-largest 4G network and the second-largest 5G network. Want to see what kind of coverage Verizon offers in your neck of the woods? Check out our interactive map below.

Verizon 4G Coverage in Arizona

The Verizon 4G network is significantly smaller than AT&T’s, covering 55% of the map, though residents of the state’s larger metro areas will have no problems with service–the more densely populated areas south of Flagstaff have solid coverage and minimal dead zones.

Verizon 5G Coverage in Arizona

Verizon offers more 5G than AT&T, but its high-speed network still trails behind T-Mobile, with a network coverage area of just 15%. More than half of that network includes 5G Ultra-Wideband, which offers extra fast service and minimal lag.

AT&T Coverage Map in Arizona

AT&T offers solid coverage in Arizona, including the largest 4G network in the state. Unfortunately, it also has the smallest 5G network, leading to coverage that’s reliable but slower than the competition. Interested in seeing what kind of service AT&T offers in your neighborhood? Enter your address in the interactive coverage map below.

AT&T 4G Coverage in Arizona

AT&T offers the most 4G coverage in Arizona, with enough towers to provide service to over 64% of the state map. Coverage is strongest in the urban sprawls of Phoenix (including Glendale, Gilbert, Buckeye, Mesa, and Chandler) and Tucson, though customers will receive signals throughout much of the state, even if it might sometimes be weaker. 

AT&T 5G Coverage in Arizona

Despite its expansive 4G coverage, AT&T offers the smallest 5G coverage map in Arizona, with a network that only covers 12% of the map. The good news is that almost all of that network includes AT&T 5G+, which offers high-speed service and minimal latency. 

AT&T 5G is mostly available in the state’s urban hubs–including Phoenix, Prescott, Flagstaff, and Tucson–though it’s also available in some of the more rural stretches of the state, including Petrified Forest National Park and Lake Mead.

Small Carrier Coverage in Arizona

AT&T, Verizon, and T-Mobile may be the largest cell phone carriers in the country, but they’re not the only ones. There are plenty of smaller carriers, called MVNOs, that operate on the Big Three networks and provide discounted coverage to their customers. 

If you don’t need all the luxuries of an unlimited data plan, then an MVNO (like Mint Mobile or Boost Mobile) might be the best way for you to score access to the AT&T, Verizon, or T-Mobile network for cheap. You can check out some of the most popular MVNOs below:

Things to Know about Cell Phone Coverage

Cell Phone Coverage Speeds

When it comes to cell phone coverage, you don’t just need a cellular signal—you need that signal to provide adequate speed. That’s why it’s important to distinguish between 4G and 5G coverage in your area. In general, 5G provides faster speeds and greater reliability than 4G. However, that’s not always the case, as there may be instances when the speeds of these respective coverage types are actually quite similar.

How to Get the Best Cell Phone Coverage

There’s more to getting the best coverage than just signing up with the carrier that offers reliable service in the places you spend time. These include: 

  • Your phone: The newer and more cutting edge your device, the more likely you’ll be able to tap into the fastest speeds. Some older phones don’t have the built-in technology to connect to the fastest 5G bands, resulting in slower service. The newest 5G devices, like the Apple iPhone 16 or Samsung Galaxy S24 series don’t have this problem. 
  • Your software: It’s important to make sure your software is up to date, as an out-of-date operating system can translate to an inability to connect to the fastest network speeds. 
  • Your cell phone plan: Depending on the mobile plan you have, your data may experience deprioritization during times of network congestion. If this is consistently happening to you, it may be worth investigating whether you can sign up for a plan that includes more premium (i.e. un-deprioritized) data. 
  • Your location: Certain types of coverage, like high-band 5G, has difficulty penetrating solid materials, like concrete walls. As simple as it may sound, moving to an unobstructed location may help you connect to these fast networks more reliably. 
Our methodology
We sourced our cell phone coverage metrics from the Federal Communications Commission (FCC), which collects data voluntarily submitted by the four major national carriers (Verizon, AT&T, T-Mobile, UScellular). Read More
The FCC incorporates standardized propagation model assumptions into its data, and notes that a user’s actual experience may vary based on end-use factors like network congestion and terrain. Read Less
