Who is the fastest 5G carrier in the US?

According to the latest report from RootMetrics T-Mobile may have the fastest 5G speeds and greatest 5G availability, but what about reliability?

When measuring only 5G reliability, a different carrier, Verizon, came out on top.

The timing of this testing however, is important to note. 5G performance was done during the second half of 2021. At the start of the New Year, you may recall that Verizon and AT&T were finally able to turn on their new C-Band 5G coverare, which brings faster average speeds to a greater number of people (more than 90 million, according to Verizon). AT&T has only a handful of cities covered at this point.

The RootMetrics report gathered results from tests that were run in 125 of the largest cities in the U.S. In the end, they found T-Mobile had the fastest 5G download speeds in 48 markets, compared to three for Verizon and zero for AT&T. Median download speeds for T-Mobile topped 100 Mbps in more than half the cities RootMetrics tested in. In 26 markets, the speeds topped 200 Mbps.

T-Mobile was also determined to have the best 5G availability. With the highest availability in 83 tested markets, T-Mobile topped AT&T (62 markets) and Verizon (6 markets).

In comparison with 5G reliability, T-Mobile was actually found to have the lowest amount at 19. Verizon had the best in 93 markets, also topping AT&T, which only showed in 67 markets. 

These findings weren’t just determined by RootMetrics either. Their results are right inline with what has been seen from other third party testers. Back in January, OpenSignal published a 5G performance report in which T-Mobile not only had the fastest 5g download speeds, but was 93.9 Mbps faster than its closest rival. T-Mobile also came out on top for availability and reach.

When comparing T-Mobile’s approach to the 5G rollout to that of AT&T and Verizon’s, it’s clear that T-Mobile got ahead by using sub-6GHz spectrum to create a far-reaching 5G nationwide network. The network now reaches more than 310 million people. More recently, they’ve begun using mid-band spectrum — much of it obtained through the merger with Sprint — to boost speeds. T-Mobile calls this their Ultra Capacity 5G service and it covers some 210 million people.

Verizon and AT&T started their 5G journey by concentrating on mmWave-based 5G. This can be very fast, but has a limited range. mmWave-based towers are in select cities. To provide more coverage, but at slower speed, the two carriers use sub-6GHz 5G.

After a few delays and limitations AT&T and Verizon were able to roll out more coverage in January, this time on the faster C-Band spectrum. The higher band spectrum has a wider reach than mmWave, enabling both carriers to reach more people with faster 5G service. In Verizon’s case, they have more than 90 million people being covered with the carrier’s fastest Ultra Wideband 5G. AT&T is rolling out its C-Band 5G, though on a more limited basis currently.

C-Band tests have been done in a number of different locations and already seems to be improving performance for Verizon. Right after C-Band 5G went live, testing firm Ookla published a report claiming that Verizon’s average 5G download speed jumped to 116.3 Mbps from 76.5 Mbps within the course of a week. For comparison, T-Mobile speeds increased from 182 Mbps to 187.1 Mbps in that same time period.

With the recent upgrades and third party tests that have come out, it would seem the leader board is bound to shift by RootMetrics’ next test. Only time will tell!

5G Stats from RootMetrics Favors T-Mobile

As T-Mobile’s lead in the 5G race soars – both in speeds and reliability – AT&T and Verizon’s positions are too close to call at this time. This is according to newly released data from RootMetrics (refer to the November Scorecard). Tests were completed in about 60 cities, out of a total 125 they will eventually incorporate for later tests. T-Mobile US had the most 5G availability in 42 cities, AT&T led in 25 markets and Verizon in 4.

Cities with the most 5G coverage were also reported. Specifically, RootMetrics reported cities where each of the carriers had achieved the most extensive amount of 5G coverage. This includes:

  • El Paso, Texas (98% 5G coverage by T-Mo) 
  • Indio, California (96.8% 5G coverage by AT&T) 
  • Rockford, Illinois (91.7% 5G coverage by Verizon)

The cities where each carrier clocked the fastest speeds thus far during RootMetrics testing were: 

  • Kansas City, Missouri, where T-Mobile US achieved a blazing 273.3 Mbps 
  • Ann Arbor, Michigan, where Verizon’s network registered median 5G download speeds of 98.3 Mbps 
  • Milwaukee, Wisconsin, where AT&T saw median 5G download speeds of 71 Mbps

In this round of testing, Patrick Linder, CMO of RootMetrics, said in a statement, “We…witnessed firsthand just how dynamic the 5G race can be, with a new leader for speed and a shift in the reliability standings since our testing in the first half of 2021. With another 65 markets to test and all carriers aggressively continuing 5G deployment and optimization, things could certainly change again as we continue our 2H 2021 testing.”
