San Antonio Cell Signal Strength
There are 10,789 map hexes within the census-defined boundaries of San Antonio. 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 | 20% | 70% | 11% | 0% |
| T-Mobile | 45% | 39% | 12% | 4% |

For most purposes, decent signals are perfectly sufficient. Weak or non-existent signals cause far greater degradation in user experience.
