T-Mobile US garnered the overall best 5G experience in the second half of 2022, per Rootmetrics, but AT&T also had a strong performance at the state level and Verizon did particularly well at the metro level. That’s a bit of a role reversal, considering that T-Mobile US used to have its primary strength at the city-level rather than nationally.
Overall, Rootmetrics said, 5G performance in the United States is “strong in general and should only improve over time as 5G continues to mature and expand.”
