AT&T Wins Americas Wireless Crown for 17th Straight Year — And the Numbers Explain Why
AT&T has once again claimed the top spot in Brand Keys’ 2026 Customer Loyalty Engagement Index, beating out Verizon and T-Mobile for the 17th consecutive year. Here is what sets the country’s oldest phone company apart — and why investors and consumers should pay attention.
America runs on wireless. According to the CTIA, a U.S.-based trade association representing the wireless communications industry, 98% of Americans own a cellphone, and 89% of those surveyed say they cannot live without their smartphone. Remarkably, Americans now rank wireless access in their community as more important than having good schools. That makes the competition between AT&T, Verizon, and T-Mobile far more than a business story — it shapes how the country connects, communicates, and operates.
In 2026, brand research consultancy Brand Keys examined 1,119 brands across 106 categories using its proprietary Customer Loyalty Engagement Index (CLEI) — and one familiar name rose to the top of the wireless services category. The result confirms a pattern that has now held firm for nearly two decades. Read on to find out which carrier earned the crown, and what fuels its lasting edge.
The $352 Billion Arena: How Americas Big Three Wireless Carriers Stack Up
AT&T, Verizon, and T-Mobile collectively generated more than $352 billion in revenue last year fool, making wireless services one of the most lucrative and contested sectors in the American economy. Despite a saturated market, the industry rewards carriers that consistently outperform on network quality, coverage, and customer experience.
All three carriers are thriving. AT&T and T-Mobile recorded historically low postpaid phone churn rates of 0.98% and 0.93%, respectively, in 2025. Verizon, meanwhile, projects retail postpaid net phone additions of between 750,000 and 1 million in 2026 — two to three times more than it recorded the previous year.
The numbers tell a story of an industry firing on all cylinders. Yet within that competitive field, one carrier continues to separate itself.

AT&T Takes the Crown — Again
For the 17th consecutive year, AT&T tops Brand Keys’ Customer Loyalty Engagement Index in the wireless services category. The ranking measures how well brands meet — or exceed — consumer expectations, with top performers demonstrating stronger loyalty, higher engagement, and predictive operational outperformance.
The Coverage Advantage
AT&T holds a unique historical and structural advantage. Founded in March 1885, it is America’s oldest phone company, and today its network covers over 99% of the U.S. population. Whether customers demand 4G LTE or 5G service, AT&T delivers near-universal reach across the country.
A $150 Billion Network Commitment
AT&T does not simply rely on its legacy. From 2020 through 2024, AT&T spent over $150 billion on its network, including spectrum acquisitions. That figure reflects a sustained, aggressive strategy to stay ahead of rivals in coverage depth and network speed.
AT&T currently acquires an additional 50 megahertz of low-and-mid-band spectrum covering roughly 400 U.S. markets from EchoStar to strengthen its 5G services — a $23 billion deal expected to close in mid-2026. fool Beyond that, AT&T announced plans on March 10, 2026, to invest $250 billion in U.S. telecom infrastructure, hiring thousands of additional workers and expanding high-speed networks nationwide.
Industry Recognition Backs the Data
Last year, RootMetrics named AT&T the winner in three major categories: “Best Overall,” “Most Reliable,” and “Fastest” wireless network — a rare triple distinction in a field dominated by strong performers like Verizon and T-Mobile. fool

The Hidden Engine Behind ATTs Low Churn Rate
A key but often overlooked driver of AT&Ts success is its surge in broadband net additions. While broadband no longer commands the explosive growth it saw at the turn of the century, 5G internet now serves as a powerful incentive for AT&T to encourage higher-margin service bundling among its existing customers. fool That strategy directly supports the carrier’s churn rate of less than 1% — one of the lowest in the industry.
Keeping customers connected to multiple services makes switching costly and inconvenient. AT&T turns network investment into sticky, long-term revenue — and that formula keeps showing up in loyalty rankings year after year.
