2021/09 Mobile Data Performance in 4 Markets - Audit Report

T-Mobile has the fastest 5G Mobile Network.

We have analyzed the mobile networks in the US with regards to 5G mobile network performance.
We took a closer look at four US markets (Norfolk VA, Detroit MI, Indianapolis, San Bernardino and Riverside, CA) to see how the operators are performing in these lively centers of business, politics and culture. We tested and measured the downlink and uplink performance of data services reflecting user experience using a 5G capable smartphone (Samsung Galaxy S21 Ultra) in Mobile Experience Tests.

  • T-Mobile‘s 5G ‘Ultra Capacity’ download speed exceeds 183 Mbps in average, and goes up to 258 Mbps per market.

  • T-Mobile shows clearly faster average 5G download in all measured cities than the other operators.
