AT&T	100%	90%
T-Mobile	100%	99%

US Cellular does not have native coverage in Somis. However, some US Cellular subscribers may still have coverage in Somis thanks to roaming agreements.

The 1% figure for Dish may understate what subscribers in Somis experience after accounting for roaming agreements.

Somis Cell Signal Strength

There are 72 map hexes within the census-defined boundaries of Somis. 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	33%	62%	4%	0%
T-Mobile	17%	60%	24%	0%
Verizon	0%	85%	15%	0%
Dish	0%	0%	1%	99%

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