AT&T, Verizon, Comcast, and Charter all outpaced T-Mobile in broadband speed performance, according to a new report from Opensignal, the independent mobile analytics firm.
The report ranked T-Mobile last among the five major U.S. broadband providers across key speed metrics, including download and upload performance.
Opensignal measures real-world network experience by collecting data from users’ devices, rather than relying on controlled lab tests. The method reflects speeds that consumers actually encounter day-to-day.
The findings mark a notable setback for T-Mobile, which has aggressively expanded its home internet service — known as T-Mobile Home Internet, a fixed wireless access product that delivers broadband over its cellular network — as a direct challenger to traditional cable operators such as Comcast and Charter.
Fixed wireless access, or FWA, routes home internet through mobile spectrum rather than physical cables. T-Mobile has positioned the product as a low-cost alternative for households underserved by cable infrastructure.
Despite that expansion, the Opensignal data showed cable providers retained a speed advantage over T-Mobile’s FWA offering. Comcast and Charter, which operate the Xfinity and Spectrum brands respectively, deliver service over hybrid fiber-coaxial networks that carry higher bandwidth capacity than cellular connections.
AT&T and Verizon also topped T-Mobile in the rankings. Both carriers offer a mix of fiber-to-the-home and FWA products, giving them a broader infrastructure base from which to compete on speed.
T-Mobile has not publicly responded to the Opensignal findings.
The U.S. broadband market remains intensely competitive. According to the Federal Communications Commission, roughly 14.5 million American households still lack access to fixed broadband at speeds of 25 Mbps download and 3 Mbps upload — the agency’s baseline definition of broadband service — creating a large addressable market for FWA providers including T-Mobile.
T-Mobile reported adding approximately 300,000 net new home internet customers in the first quarter of 2025, bringing its total FWA base to around 6.4 million subscribers, according to the company’s first-quarter earnings filing.
