No reception at all on Interstate 80 west of Laramie. I even got off the highway and trolled through a couple of towns, and got nothing.

There is no T-Mobile service in Kittredge.

AT&T network is terrible in Lafayette. My wife and I are switching.

AT&T has been absolutely useless in Telluride since installing its tower here and taking over this area. It's a running joke in this town, as I just had a client come into my office and, when asked about his CPA's phone number, he said "I've got it, but can't make any phone calls on my phone".. I said, "Oh, you've got AT&T too!". It's more and more frustrating when I can't get a hold of my wife to check on my 15 month-old baby! We had someone come into our office talking about this issue, saying that they called AT&T customer service to complain and the rep said "Well, you know we were forced by the government to take over your area, so we really don't intent to provide proper service there"!

Before At&T bought out Alltel I had great coverage even in the canyon between Salida and Coaldale. Now we get no signal. What a rip off. I couldn't get a straight answer as to why from any customer service rep at AT&T. They should have left Alltel alone. No Verizon service here either.

Since Dec 23,2011 I have no phone service,just texting capability.its 12 / 28 now. I can't even reach AT&T customer service.

I drop calls 7 our of 8 times on this stretch of road. A colleague of mine says that she also drops calls in this stretch with Verizon.

We have had 1-2 bars until early this week where we lost it all? what happened to our cell service toward ski cooper? Hope it comes back soon or Sprint will loose my business, who is next?

Downtown Louisville has no reception at all for T-mobile, 5 bars on AT&T. Elsewhere in Louisville is OK reception on T-mobile, but zero reception downtown is a deal breaker. It means we can't be reached by a baby sitter when we go out in town.

AWFUL, no matter what phone device with AT&T. Going to switch to Verizon and see if that is better
