I can't maintain a call, receive texts, or voicemails any where from 9th St.on west.

Att is a continual hastle, have to go to the front of the house or 2nd fl to get reception, will switch to another carrier as soon as contract is up next month, N. Boulder in general is bad with ATT.

Poor reception with frequent dropped calls two blocks weat of Broadway on North St.

I use my cellphone around SE Boulder County, Broomfield County, and Adams County. The phone service is frustratingly poor. More than 1 / 3 of my calls drop. The rest typically suffer from poor reception / fading.

Most of the time reception is very good. Occasionally will get a dropped call or the bars will go down for a short time.

AT&T coverage is terrible in Boulder. If you look at their map it lists almost all of Boulder as having good reception, but try driving down Iris and maintaining a call.

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!

Have had AT&T going back to the Cingular days. Used to be happy with it. Getting really ticked off lately though. 2G voice coverage was really good with a decent phone like the blackberry curve. Have a Samsung zx20 3G phone that was also good when only on 2G. Since 3G has arrived, it has just gotten worse. The 3G signal is weak almost everywhere and calls are dropped all the time. North Boulder is particularly horrible inside any building. 2G coverage on the Curve, which used to be solid, is worse and now has frequently lousy voice quality and dropped calls. I have started using my landline again for family calls, due to how bad the call quality has gotten. Even with 4-5 bars, calls are static, crackle and pop. Clearly, the AT&T 3G rollout has had issues, probably due to all the Iphones overloading the network. If it doesn't get better in a month or so, I'm switching to somebody else.

Reception was very good when I first got the iPhone in October 2008 - better than Verizon (which I'd switched from). However, sometime around July 2009, service suddenly got much, much worse - tons of dropped calls, poor call quality, signal fading in and out. Sometimes you'll be looking at the phone with full bars, sitting in one place, and the bars / 3G symbol will just suddenly disappear entirely for 10 seconds, then return. Rumor is that AT&T is upgrading the network and that's causing the current issues, and that it will be resolved soon. Hope so, otherwise I'm heading back to Verizon.

Had good coverage at home until the last couple months. Dropping calls from home all the time. Will be switching soon.

Get 5 bars, but the call quality is terrible!

I have tried to call AT&T 5 times to complain but my calls always drop before I can get any real help.

Reception is very good (5 bars), but the system is apparently overloaded as it drops calls or have intermittance voice - breaking down. This started last month and ATT says they will solve the problem by October. I am switching away.

At&t service getting worse,they must have redirected tower, can only use in one room in the house and sometimes outside. Other household members and guests seem to have better luck with Sprint and T-Mobile by a bar. Pathetic!

Many specific dead areas in Boulder and areas that drop calls regularly. Horrible service quality.

We switched to AT&T to get the iphone. We continually have poor service in our house and have to call clients back on a landline. The coverage fades in and out. We had strong coverage with Sprint before switching.

terrible coverage at my home near 75th and Baseline. Always drop outs on Baseline east of 95th street and on McCaslin near Harper Lake. East Boulder County between Boulder and Louisville is a weak area for AT&T coverage.

I just switched from Verizon in order to get an iPhone. I have a basement office in my house and use my cell phone extensively. The ATT coverage is terrible. Calls cut in and out. I can't converse with my clients I hate to do it, but will probably have to go back to Verizon. Calling ATT today produced no satisfaction. Verizon was 4 bars.

Never above 2 bars of service, constant missed calls and garbled messages. I can always hear the other person fine, but they can never hear me. Driving me nuts.

Worst coverage of any carrier here.Iphone is great but if you live near here you will be mad at AT&T. Guess what... They don't care!
