Poor reception outside of Boulder, Lafayette. Great reception in downtown Denver where I work. Decent coverage in the mountains, better than that at home!

I get full reception but calls are dropped all the time. I can hear other people, but no one can ever hear me. I have to drive a few miles away and call them back, then it works fine.

There is this stretch on 36 (the hill between Superior and Boulder) that no matter what (it never fails) my calls always drop (while dricing it through it). My bars go to none and my calls are dropped. Dr.1 mile service comes up again (still not great).

So, my experience with AT&T TDMA seems to be the exception. Signed up Fall, 2003. Got quality advice from salesman at local AT&T store. Very honest. Said that, while GSM is much better tech, the Denver area coverage for AT&T was mediocre and would take awhile to improve. I was looking for coverage in the mountains, and he firmly recommended the older TDMA network. Boy was he right. Service has been good to very good through much of the Boulder area. I get solid reception in my house, and while signal varies around town, very rarely can I not make or receive calls. Works in Broomfield, Louisville, Longmont, etc. Heck, works great in Leadville, CO. GSM quality (based on calling from store demo phones and leaving self a voicemail) is definately better, and the future. But the darn phone needs to work more places then the airport and the freeway. My contract is up, but I will roll month to month, at least until the local GSM coverage from Cingular (AT&T) is improved. Salesman did think that GSM would improve once the merger was complete and Cingular had a chance to upgrade the local plant in this area. Finally, he strongly recommended the not-so-fancy-but-free Nokia phone. While not snazzy, he said it had the best antenna of the TDMA models avail. Normally I never trust salesman, but the guy earned his commission. I'm a satisfied customer.

reception was excellent until a few weeks ago, but now it is off most of the time. Comes on for brief moments, often not even enough for sending an SMS. I wonder what happened.

Outside reception is Perfect. Inside the house is good near the windows. In the middle of the house, reception is average. Have been a T-Mobile customer for 10 years and very satisfied with their service.
