The 88% figure for Dish may understate what subscribers in Coronado experience after accounting for roaming agreements.
Coronado Cell Signal Strength
There are 294 map hexes within the census-defined boundaries of Coronado. 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 | 11% | 72% | 14% | 3% |
| T-Mobile | 32% | 63% | 3% | 2% |
| Verizon | 43% | 55% | 0% | 2% |
| Dish | 6% | 49% | 33% | 12% |
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, 133 hexes in Coronado that fall in bodies water, along rivers, or near shorelines are excluded from the table above.
