4G LTE & 5G Coverage In Vallejo
The table below shows the proportion of Vallejo with coverage from different cellular technologies.| Network | 4G Coverage | 5G Coverage |
|---|---|---|
| AT&T | 98% | 94% |
| T-Mobile | 100% | 100% |
| Verizon | 100% | 99% |

US Cellular And Dish Roaming Coverage
US Cellular does not have native coverage in Vallejo. However, some US Cellular subscribers may still have coverage in Vallejo thanks to roaming agreements.
The 47% figure for Dish may understate what subscribers in Vallejo experience after accounting for roaming agreements.
Vallejo Cell Signal Strength
There are 803 map hexes within the census-defined boundaries of Vallejo. 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 | 9% | 52% | 38% | 2% |
| T-Mobile | 47% | 48% | 5% | 0% |
| Verizon | 46% | 52% | 2% | 0% |
| Dish | 1% | 29% | 16% | 53% |
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, 81 hexes in Vallejo that fall in bodies water, along rivers, or near shorelines are excluded from the table above.
