Higher score than in Q2
P3 said T-Mobile scored 8,368 out of 10,000 points in the latest benchmark, up from 8,274 points in the previous quarter. The result follows T-Mobile's win in Q2 2026, which means the operator has now defended its title. P3 said the score reflects strong performance in network quality, customer experience, coverage, reliability and AI-Readiness.
The consultancy listed 13 categories in which T-Mobile took the lead:
- Consumer Experience Champion
- Industry Experience Champion
- AI-Readiness Champion
- Voice Champion
- Data Champion
- Media Champion
- AI-Services Champion
- Coverage Champion
- Urban Champion
- Non-Urban Champion
- Reliability Champion
- Performance Champion
These category wins resulted in the overall P3 Test Champion title.
The AI angle
A notable part of the announcement is its focus on AI. P3 CEO Hakan Ekmen said that "As AI assistants and agents become part of everyday life, users increasingly depend on low latency, strong uplink performance and reliable connectivity everywhere, from city centers to rural roads."
Ekmen added that by winning both the AI-Readiness Champion and AI-Services Champion titles again, T-Mobile "demonstrates that it is building exactly the foundation needed for this AI-driven future." P3 describes its benchmarking methodology as the industry standard for network quality, customer experience and, now, AI-Readiness.
Size of the dataset
The study is based on more than 2.2 billion network samples collected between July and September 2026. According to P3, the data covers 96.6% of the U.S. population and 92.3% of its built-up area. P3 calls it one of the most comprehensive and statistically robust assessments of mobile network performance in the U.S. market.
The results rest on what P3 calls its independent, globally consistent Benchmarking Methodology. The company says its network analyses aim to drive continuous and sustainable improvements in network quality and customer experience, creating value for operators and consumers.
What it means for users
For mobile customers in the United States, the report is an independent comparison of network performance, including in non-urban areas, where T-Mobile also took the top spot according to P3. The inclusion of AI-related categories shows that the consultancy now treats latency, uplink performance and consistent connectivity as measures of how well a network supports AI assistants and agents. The announcement does not give scores for other operators, so the source offers no detail on how close the competition was.
