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 second-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 is 11% behind Verizon when it comes to national 4G coverage. Recently T-Mobile beat out AT&T by 1% for the number two position. However, that 1% margin comes with a caveat: 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) are 600 MHz capable. Similarly, only a handful of newer Galaxy phones can access the spectrum.
- Verizon: 70% 4G coverage
- T-Mobile: 59% 4G coverage
- AT&T: 58% 4G coverage
- Sprint: 27% 4G 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
T-Mobile Coverage Map
T- Mobile’s 4G network covers 59% of the United States. This wasn’t always the case, as T-Mobile has tripled their national LTE 4G coverage in the last three years. If you left T-Mobile and are looking to come back, or want to try it out for the first time, it’s a great time to do so.
