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

Excellent reception in Gunbarrel and around Boulder. Maybe 1-2 dropped calls in 5 months. Reception not so great in the mountains.

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.

Very good reception in other parts of Boulder near university.

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.

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.

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.

Works great! I am going to cancel my land line.

I had AT&T, my wife Voicestream (pre-TMobile), her's always worked mine dropped constantly. I went to TMO and haven't regretted, works well at home and work near Crossroads Mall. Neighbors have Sprint and Verizon, iffy coverage on all, if you're in north BOCO TMO seems to have the best coverage. Dropped calls are inevitable with any carrier. Try holding a call driving south on 93, impossible any carrier. Rarely happens with TMO. Now if only they would straighten out their VM!

Reception from the new Holiday Neighborhood has been pretty reliably strong with good connections and only rare dropped calls. My girlfriend (located on same block) had problems with dropped calls and bad reception up till a few months ago using a Motorola V300. (it is a smaller flip phone with perhaps smaller antenna) Now it is better too. Not sure if they added coverage to boost the signal, or if it is much better at the other side of the block where she moved to. Tmobile is decent company. Decent customer service but I'm tired of paying to replace my Nokia 3650 every 8 months or so when it gets flaky, so will try another company (cheaper to get new plan with another company.)

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.

im actually getting service, yea meybe not great service but when your used to NO RECEPTION from att, anything is something. T-Mobile seems to work well, in and around columbing elementary. judging from the review on this site it may be the only service provider with decent service.

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

At ground level, reception is fairly decent almost everywhere I go. Above ground level, such as on the second floor of a building, reception is great. Only problem I have with T-Mobile is when they have issues on their side. I have had T-Mobile service for about a year, and they have had three times where all data signals are dead, so texting, email, and mobile web browsing is dead. Reception in the mountains is non-existant. Verizon picks up in a lot of locations T-Mobile won't. However, Verizon doesn't have as good of reception on the flat ground as T-Mobile does. Not many dead spots when traveling around the front-range. You can be on the phone the entire time while going from Ft. Collins to Denver and not lose the call. There are places where reception isn't great, and you may have to ask the other person to repeat themselves a couple times, but you won't lose the call. I have had quite a few dropped calls, but only 2 or 3 of them were from my side. All the others were because the other person dropped the call. T-Mobile, however, has very poor customer support. If you're looking at getting a new service provider, consider T-Mobile. Just be careful of the few times where you may need to call customer support, because it'll be a nightmare beyond belief.

Can't even have a conversation at my new house... .it is so choppy! the whole conversation consists of "what"... .."what"... ... "can you hear me now?"

I get good reception through most of boulder with some spots of low signal

I commute between Boulder and Broomfield. I can count on losing my call at least twice during the drive: once at the top of Davidson Mesa and once going under McCaslin Blvd. I also sometimes lose calls going past Storage Tek. I never had these problems with Verizon, so I'll probably switch back.

works wonderfully everywhere... .except the mountains (where I spend most of my time) and then service is absolutely non-existent.

Sometimes spotty, but typically good. Though I can't explain why at 2:03 and 2:05 a.m the phone drops calls every single day. Also I have the problem with calls dropping getting over the hill on 36 between Superior and Boulder, like it seems so many do.

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.
