4G LTE & 5G Coverage In Detroit
The table below shows the proportion of Detroit with coverage from different cellular technologies.| Network | 4G Coverage | 5G Coverage |
|---|---|---|
| AT&T | 100% | 100% |
| T-Mobile | 100% | 100% |

Don't be alarmed by Dish's lack of 4G coverage in Detroit. Dish has a newly-built network that's 5G-only.
US Cellular And Dish Roaming Coverage
US Cellular does not have native coverage in Detroit. However, some US Cellular subscribers may still have coverage in Detroit thanks to roaming agreements.
Millimeter Wave 5G
Parts of Detroit have millimeter wave 5G coverage. This novel celluar technology offers extremely fast speeds, but the coverage potential is limited. Millimeter waves aren't well-suited for traveling long distances.
| Network | Millimeter Wave |
|---|---|
| Verizon | ✓ |
| AT&T | ✓ |
| T-Mobile | ? |
Millimeter wave coverage in Detroit is likely sparse (mostly limited to dense, outdoor areas like popular parks or sports stadiums).
Detroit Cell Signal Strength
There are 3,379 map hexes within the census-defined boundaries of Detroit. The table below shows the proportion of hexes at various levels of signal strength. Where both 4G and 5G coverage is available, data is drawn from whichever technology offers a stronger signal.
| Network | Strong | Decent | Weak | None |
|---|---|---|---|---|
| AT&T | 19% | 75% | 5% | 0% |
| T-Mobile | 80% | 20% | 1% | 0% |
| Verizon | 29% | 68% | 2% | 1% |
| Dish | 8% | 79% | 11% | 1% |
For most purposes, decent signals are perfectly sufficient. Weak or non-existent signals cause far greater degradation in user experience.
Due to data-reliability concerns, 71 hexes in Detroit that fall in bodies water, along rivers, or near shorelines are excluded from the table above.
