There are four major cell phone carriers here in the United States: Verizon, T-Mobile, AT&T, and Sprint. Of these “Big Four,” T-Mobile has the third-most nationwide coverage. T-Mobile is quickly expanding, so their network is likely to get even bigger and faster in the near future. This guide will give you a look at the T-Mobile coverage map and how it compares to its closest competitors.

T-Mobile Compared

T-Mobile is 8% behind Verizon and 6% behind AT&T when it comes to national 4G coverage. T-Mobile’s 4G network runs on the 600MHz spectrum, and right now only select new phones can connect to it. For example, when it comes to iPhones, only the iPhone XR (or newer) is 600 MHz capable. Similarly, only a handful of newer Galaxy phones can access the spectrum.

  • Verizon: 70% 4G coverage
  • AT&T: 68% 4G coverage
  • T-Mobile: 62% 4G coverage
  • Sprint: 30% 4G coverage

Verizon has the most 4G coverage.
AT&T has the most 3G coverage.

While T-Mobile’s 4G network is quite robust, the carrier’s 3G network lacks breadth. 3G acts as a fallback when a 4G signal is unavailable. The lack of 3G coverage can be a drawback if 4G coverage is spotty in your area.

  • AT&T: 70% 3G coverage
  • Verizon: 62% 3G coverage
  • Sprint: 25% 3G coverage
  • T-Mobile: 22% 3G coverage
