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.
Just moved to Boulder... have lived all over country and besides rural Alaska this is the worst coverage I have ever had. Partner has ATT and doesn't work at all. At least my Virgin phone (Sprint network) works ab out 1 / 2 time.
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.
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.
