Do You Have the Best Phone for Your Mobile Network? Here's What the Data Says

We've just published our definitive list of the Best Mobile Networks in the US for 2026, a deep-dive, data-driven report based on more than 2 million speed tests. You can read the full story here , but we can reveal that among the country's three major carriers, T-Mobile comes out on top not only nationwide but also in many of the states and major cities tested. We also delve into mobile virtual network operators (MVNOs), where Mint Mobile, owned by T-Mobile, triumphs.

But choosing the right service provider is only half the battle. You also need to figure out which phone to use. Our Best Mobile Networks dataset doesn't just cover the carriers—it also tracks the actual phones used in more than 2 million speed tests. This companion piece breaks down which phone models perform best on each network. (In case you didn't know: Not every phone performs the same way on every network.)

So how do we do this? To start, we narrow the field to 5G-capable phones that have been tested at least 1,000 times in data from our partner sites, CoverageMaps.com and BestPhonePlans . The phones must also have been available for purchase from the manufacturer as of mid-August 2026. (That excludes new phones just announced by Google , or those that will be unveiled by Apple next week.)

Using those test scores, we generate a Speed Index on a 1-10 scale. We also consult PCMag's published reviews for each phone, which we convert to a Rating Index of 1-10, as well as customer satisfaction ratings for the phone makers from our Readers' Choice survey earlier this year. 

We use all those numbers to arrive at a cumulative Mobile Phone Indexto determine which manufacturers and specific devices rank highest, both overall and for each mobile network. (Our full methodology is at the bottom of this story.)

The Best Phone Brand Across All Carriers

You've picked your carrier. The hunt for the best phone on that network starts with the platform (iOS or Android?) and the brand.

Apple has the top Speed Index and Review Index and comes in a close second to Google for Satisfaction. All of which means that Applehandily comes out on top as the Best Phone Brand across the three major US carriers (AT&T, T-Mobile, and Verizon).

When we narrow things down by mobile carrier, Appleis still the top choice. Its Mobile Phone Index rating—the final score that determines a winner here—ranges from 7.88 on AT&T to a stellar 9.01 on T-Mobile.

Knowing that not everyone embraces the Apple ecosystem, we've also calculated the top Android phone brands. Samsungis the winner here across all the networks. Its Galaxy brand phones also take the prize for Android on both T-Mobile and Verizon. On AT&T, Google'sPixel line wins.

The Best Phone for AT&T, T-Mobile, and Verizon

When the focus is narrowed to specific phones, Apple loses its advantage. The top phone across all carriers is the Samsung Galaxy S25+.

The fastest by far, the Galaxy S25+ is the only phone to earn a Speed Index higher than 9.0. Our reviewer awarded that phone a 4-star "excellent" rating, just slightly behind the 4.5-star rating ("outstanding") earned by other phones on the list, such as the Google Pixel 9a and the iPhone 17 .

The S25+ is also the top phone for T-Mobile users, even ahead of the newer S26 Ultra . However, for AT&T, the top phone by index score (8.60) is the Samsung Galaxy A36 5G , the company's midrange phone. (Note: We did not take phone price into consideration for this story.) The A36 5G on AT&T's Mobile Phone Index is boosted by its superior Speed Index as well.

For Verizon, the winner is Google's 2025 foldable, the Pixel 10 Pro Fold , which has a carrier-high Speed Index of 9.44, putting it more than a point ahead of the Galaxy Z Fold 7 . Google also benefits here as the brand with the highest customer satisfaction rating in our survey results from earlier this year .

The Top Phones on Each Carrier, Ranked

Whichever mobile network you use, we can tell you which phone, by brand, performs best on it. (This also works for MVNO users; just pick the network that owns or partners with your MVNO of choice.)

Beginning with AT&T, the top-performing phones for each major brand are: the Apple iPhone Air, the Google Pixel 9 Pro, the Motorola Edge 2025, and the Samsung Galaxy A36 5G. 

On T-Mobile, the top phones by the numbers are the iPhone 17 Pro Max, the Pixel 9a, the Edge 2025, and the Galaxy S25+.

On Verizon, the top performers are the iPhone 16, the Pixel 10 Pro Fold, the Edge 2025, and the Galaxy Z Fold 7. 

T-Mobile boasts the most phones with a Mobile Phone Index over 9.0. (Those are the Galaxy S25+ and S26 Ultra; the iPhone 17 Pro Max, 17 Pro, and 17; and the Google Pixel 9a.) Only one other carrier, Verizon, has a phone with a Mobile Phone Index above 9.0, and that's for the Google Pixel 10 Pro Fold.

Our Methodology: How We Determine the Best Phones for Every Wireless Carrier

We begin the same way we do with our Best Mobile Networks reporting, with speed, this time based on tests tied to specific phones. Our speed test data comes from BestPhonePlans and sister site CoverageMap.com . 

We limit the results to 5G phones that the manufacturers themselves have available for sale as of mid-August 2026. To be included, each phone in our results had to receive a minimum of 1,000 tests. Our data covers 2,185,418 tests made between Jan. 1 and June 30, 2026 .

We convert the average download and upload speeds (both in Mbps; higher is better) and latency measures (in milliseconds; lower is better) into a number on a 1-10 scale. To ensure speeds are consistent, we set a floor and ceiling for each rating: 

• Download speed: 30 (worst) to 350 (best)

• Upload speed: 3 (worst) to 25 (best)

• Latency: 100 (worst) to 15 (best)

Our formula combines download speed (70%), upload speed (20%), and latency (10%) to generate the PCMag Mobile Phone Speed Index.

Then we analyze the editors' rating for each phone based on its PCMag review. (We've lab-tested and rated all of the phones included.) Our review ratings are based on a 1- to 5-star scale. To get the Review Rating Indexto a 1-10 scale, we set a floor of 5 and a ceiling of 10. Most of the products covered here score above 8.5 on the index. The Satisfaction Indexis based on the scores from our Readers' Choice 2026 Phones and Carriers survey ; we use the existing ratings, which are on a 1-10 scale. (Google rates highest, at 8.9.) 

Finally, using those numbers, we calculate a final score to determine winners.

The formula: 50% Speed Index + 25% Review Rating Index + 25% Satisfaction Index = Mobile Phone Index .
