Poor service.

@Dave-kc Did you check the coverage out? https://www.att.com/maps/wireless-coverage.html

That's pretty much the largest / worst area of coverage on the eastern half of the United States. Most of it's not even AT&T coverage, it's 3rd party.

 Northern Maine is the only thing that seems to comes close, it's smaller but has a worse coverage.

@Dave-kc I don't know what the other carriers coverage looks like out there, but if this was the first map I looked at, I'd be really hoping the others had better coverage...

The carriers coverage maps are too general.  I use an App called Coverage Map by root metrics.  It shows actual user reported reception by location.  

You mentioned Lincoln NE.   There are areas for every carrier that have no service, including Verizon.  It's just a matter of what street your on.

Give the app a try.

I have areas of poor coverage in areas I travel for work, so I bought a booster for my car and it works like a charm.  Not the solution for everyone, but it's perfect for my situation.

Seriously, looking at this map you can't tell that Nebraska is SERIOUSLY DEFICIENT compared to Missouri? 

Let alone compared to the eastern half of the country...?
