AT&T has publicly accused T-Mobile of lying.

AT&T just launched a campaign that questions everything T-Mobile has been telling you.

AT&T has claimed that T-Mobile has been told to revise its marketing claims 16 times in four years by the Better Business Bureau's advertising division. According to AT&T, this is more than the consumer electronics and financial services industries combined.

AT&T's chief marketing officer, Kellyn Smith Kenny, stated in October 2025 that their network has more coverage, proven reliability, and an industry guarantee. She added that AT&T delivers dependable connectivity.

AT&T reported investing $145 billion in US connectivity infrastructure from 2020 to 2024, including spectrum investments. They state that their coverage area is now 300,000+ square miles larger than T-Mobile's.

RootMetrics data indicates AT&T has better speed and reliability, with fewer dropped calls than T-Mobile. Ookla recognized AT&T for superior call clarity and overall call performance among US carriers.

AT&T maintains its network speaks for itself. T-Mobile insists it remains the most customer-focused carrier. T-Mobile's President of Marketing, Strategy and Products, Mike Katz, defended the company's record, stating that T-Mobile is focused on customers and delivers great experiences.

This competition indicates a tight market. Both companies have subscriber growth, are expanding into home internet, and are competing for the same users. The industry is improving and the rivalry is increasing.

The competition now includes faster speeds, better deals, and more reliable connectivity for phones and smart homes, and is not just about cell towers.

Ultimately, customers will decide which carrier delivers. Personal experience is more important than marketing.

Individual needs vary, and a perfect solution for one person may not suit another. The ongoing competition between AT&T and T-Mobile may benefit consumers.
