Testing of carriers across the US shows T-Mobile with a commanding lead in 5G, winning speed tests in 24 cities and rural regions to AT&T's eight, Verizon's two
For our 12th annual test, we drove more than 10,000 miles, speed-testing AT&T, T-Mobile, and Verizon 4G and 5G in cities, towns, and rural regions all over the US.
Context & Ripple Effects
The speed crown has been changing hands for a decade: Verizon led PCMag's 2015 30-city speed tests, AT&T displaced it in 2019, and last year's Ookla coverage count already showed T-Mobile's 5G footprint at 5,013 cities against AT&T's 237 and Verizon's 39 — though Verizon still held the top speed score then.
This 12th annual drive test is the moment coverage converted into measured performance. A year after PCMag found 5G failing to live up to the hype — with AT&T's 5G largely slower than its own 4G — T-Mobile now wins 24 cities and rural regions to AT&T's eight and Verizon's two, and Ookla's H1 2024 Speed Score data later confirms the gap persisted rather than closing.
First-order effects
- T-Mobile gains the independent benchmark that validates its 5G marketing, while Verizon — which built its premium-brand reputation on speed and coverage wins — is now measured last in 5G wins with just two cities.
- AT&T's 5G rollout, which PCMag found underperforming its own 4G a year earlier, now finishes a clear second in wins, leaving both incumbents defending against a rival that owns the low-band coverage story.
Second-order effects
- Verizon and AT&T face pressure to accelerate mid-band 5G deployment to reclaim the speed crown, since T-Mobile's 2020 Ookla data showed its advantage was coverage breadth, not peak speed — Verizon's 5G still posted the highest speed score then.
- Carrier marketing shifts toward whichever metric favors each player: T-Mobile leads on measured wins, Verizon on speed scores, forcing buyers to weigh coverage against peak performance rather than accepting a single 'best network' claim.
Third-order effects
- The pattern — Verizon's 2015 lead, AT&T's 2019 displacement, T-Mobile's 2021 takeover — points to spectrum position, not brand, determining multi-year network leadership, with each generational shift in spectrum handing the crown to a different carrier.
- If Ookla's 2024 Speed Score data holds, the 2021 result marks a durable regime change rather than a one-year anomaly, raising the stakes for the next spectrum cycle as the mechanism by which the incumbents could respond.
The trend: US mobile network leadership is cycling with each spectrum generation — from Verizon to AT&T to T-Mobile — as independent drive tests and Ookla measurements increasingly decide which carrier's 5G claims buyers trust.
