Ookla's 2026 Connectivity Report: T-Mobile Dominates Mobile, AT&T Fiber Leads Fixed Internet
In the first half of 2026, a comprehensive analysis by Ookla, a telecommunications analytics firm, revealed the leading internet service providers in the United States. T-Mobile emerged as the undisputed leader in the mobile sector, showcasing superior performance across various metrics. Concurrently, AT&T Fiber distinguished itself as the premier provider for fixed internet services, demonstrating remarkable speed and reliability. This report provides a detailed overview of the competitive landscape, highlighting the strengths of major players and offering insights into consumer satisfaction.
Ookla's U.S. Speedtest Connectivity Report for the first six months of 2026 positioned T-Mobile at the forefront of the mobile telecommunications industry. The company was recognized for possessing both the best overall mobile network and the leading 5G network in the nation. Its median download speed reached an impressive 275.55 Mbps, which surged to 314.38 Mbps on its 5G infrastructure. T-Mobile's superior mobile speeds were prevalent across 47 states, with only North Dakota and Vermont not declaring a clear winner, and GCI leading in Alaska. Furthermore, T-Mobile excelled in user experience scores for both mobile and 5G networks, particularly in areas like gaming and video streaming, and was also noted for its network consistency. Despite these achievements, T-Mobile did not lead in coverage, where Verizon and AT&T secured the top two positions.
The mobile category clearly belonged to T-Mobile. Although Ookla's evaluation primarily concentrates on performance metrics rather than cost-effectiveness, T-Mobile also garnered the highest consumer sentiment. Speedtest users rated T-Mobile at an average of 3.77 out of five stars, surpassing Verizon's 3.25 and AT&T's 3.09, indicating strong customer satisfaction alongside its technical prowess.
In contrast, AT&T Fiber dominated the fixed internet sector, earning the title of the best internet service provider. It delivered a median download speed of 374.75 Mbps, making it the fastest fixed network available. AT&T Fiber also boasted the highest consistency and received the most favorable consumer ratings, averaging 3.63 out of five stars. While Verizon offered a slightly superior fixed gaming experience, based on factors like latency, upload/download speeds, and jitter, its lead over AT&T Fiber in this specific area was marginal.
Ookla's report, while presenting a national overview, also delved into state and city-specific data, providing granular insights into network performance. For instance, Kansas recorded the fastest median mobile speed at 242.56 Mbps, with T-Mobile identified as the top provider in that state. In the realm of fixed internet, Connecticut exhibited the highest median download speed of 344.24 Mbps, where Frontier Fiber was the fastest provider. The data utilized for this extensive report is derived from Ookla's Speedtest service, which collects hundreds of millions of results daily from users globally, offering a robust foundation for its connectivity analyses.
The initial six months of 2026 have undeniably established T-Mobile as the frontrunner in mobile connectivity and AT&T Fiber as the leader in fixed internet services within the U.S. These findings, based on Ookla's rigorous Speedtest Connectivity Report, underscore the ongoing advancements and fierce competition among telecommunications companies striving to deliver superior internet speeds, reliability, and user satisfaction to consumers nationwide.
