Eureka Cell Signal Strength

There are 406 map hexes within the census-defined boundaries of Eureka. 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	28%	65%	7%	0%
Verizon	32%	58%	10%	0%
US Cellular	20%	68%	9%	2%

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, 165 hexes in Eureka that fall in bodies water, along rivers, or near shorelines are excluded from the table above.
