AT&T has no tower anywhere close and your phone doesn't let you know it's roaming and the company doesn't give you any warning until the are going to discontinue you phone service so be careful

No reception, ever, South of C470 and to the West of Ken Caryl exit including the Valley and Deer Creek Rd. Verizon was just as bad as T-Mobile.

HORRIBLE RECEPTION IN CRAIG COLORADO AND SurROunDING aReAS

Have lived in the Florissant area for 12 years. I would think by now there are enough customers here to warrant a tower that would service all the potential customers. I am going to let my service expire and just go to pay as I go(for when I'm in the Springs)

Love the iPhone, but reception has degraded in recent weeks. AT&T says my nearby tower is broken and they don't know why it isn't fixed yet. Apple says AT&T is too busy in Vancouver to fix Denver. Verizon has coverage but Storm evidently sucks. Maybe class action suit (breach of contract) would help, like another poster suggested. ~D

have to use at&t, Verizon won't work

No reception at all... .this is supposedly a major nationwide provider?

In the past 6-9 months the reception has gone from bad to none. Dropped calls, no bars in areas a couple of years ago I did have.

Been with AT&T for years, this summer service went really bad, customer care says nothing meaningful, rumor has it they are upgrading system but no one can tell when this poor service will end. Switching to Verizon in October 09 along with all my neighbors!

No reception with AT&T on Hwy. 86 from Franktown Intersection to Elizabeth. Also there is no reception in any neighborhood near this road.
