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.

Just switched from Verizon to ATT to get the new iPhone, but will likely switch back to Verizon as ATT coverage is pathetic

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!

Terrible reception in this pocket of Boulder. Always have dropped calls, always miss words. I use my cell phone at home basically to take calls then call the person back from my land line. Have AT&T now, but it was just as bad when I had Verizon.

Bad, Bad, Bad. Someone place an antenna in this area so we might have a signal.

Disappointing service, especially when you consider that this is the "high tech" district in Boulder...

Very poor voice quality, wireless signal and reception.

Good overall coverage, even in my home. I lose calls over the hill coming in from Superior, but other than that, reception is very good.

Cingular reception is terrible! My calls get dropped every few minutes and always have missed words.

Signal strength typically varies from 0 to 2 bars. For somewhat reliable conversations, I need to go to the 2nd floor to talk.

Terrible reception. Will get dropped on almost every call. Have to have all my people call me on my land line. Useless Service.

I have been with T-Mobile for 6 years. Over the last 2 years coverage has gotten steadily worse. I now get almost no reception in my home, and occasionally the phone can't even find the network. Outside coverage is between 2-3 bars, though dropped calls and poor quality are very common for me. I have asked them to come and investigate the coverage issues as neighbors agree that they've seen coverage go down - but until enough people call they won't come out.

Virgin mobile prepaid minutes plan has given us great reception with no hidden costs (i.e. massive TAXES). Virgin mobile uses the Sprint network. When we moved here 5 years ago I had Verizon wireless on a satallite plan which I signed up for in NY. I had great reception with the satellite but when I switched off of satellite the reception was useless in Boulder. I went without a cell phone until I tried Virgin Mobile at a risk of $25 that covered the cost of the phone + $20 in airtime.

I have terrible reception: lots of static, many missed words. Lookinf for a signal boost machine.

I have had AT&T / Cingular and Verizon. My daughter has had Cricket and T-Mobile. Does anybody know if there is a carrier out there that will get service up Flagstaff?

Coverage is spotty in the house, not much better outside. What I have heard is that the Federal government has a radio listening station, these are the big radar-looking antennas north of Boulder, just east of the road to Lyons. Because of the antennas, the cell companies are not allowed to have a lot of power. Just check the cell tower maps, there are none anywhere near those giant antennas.

Terrible reception or none at all here in my neighborhood. Constant dropped calls all over town, particularly north Boulder. I would estimate that 50% of my calls fail in Boulder, and 90% of them fail on the north side of Boulder. I bought my iPhone (which I love) before moving here, and boy is AT&T coverage a huge problem. From what I hear, no networks here work well. I cannot believe it's been this bad for years and no networks are stepping up. Incredible.

Very flakey coverage. Dropped calls. 0-1 bars. In 2007 to have this level of service is kind of depressing. Don't see this getting better because why is it so bad now?
