My AT&T service is spotty at best. My iPhone 3G is primarily on EDGE and I'm in the business district of Chicago. The service is unuseable during busy hours like early rush, NOON and pm rush. AT&T is useless in Chicago. I'd highly recommend Sprint or TMobile in the Windy City.

I live in the Museum Park area of the South Loop. I was very pleased with Verizon for the 6 or more years that I used them before I moved to this area. I can only use my blackberry while standing in front of the balcony doors and sometime it still drops calls. The only reliable place is actually standing on the balcony. This is very tough to deal with in the colder months.

Usually just 1 bar in house, half calls flip straight to voicemail- not reliable. Replaced phone but same issues. Outside OK.

My calls are constantly dropped. I moved to Chicago from Indiana recently. In Indiana, my reception was great. Now, my calls always end early or "can you hear me?" I'm switching as soon as my contract is up.

I can text all day (unless there are major delays) but calls regularly get dropped and it's the 'can you hear me now?' conversation every other minute even if the call doesn't drop. For reference, I live at Addison just west of the 90. I consider the poor service AT&T has been having lately to be a breach of contract. I'm paying for a service. That service isn't being provided to me. I either get a discount for the days I report bad service (even Comcast does that!) or I get to leave my contract any time without an ETF. Even when AT&T was still advertising with their 'fewest dropped calls' campaign, the calls might not drop but they would degrade so badly you couldn't even hold a conversation without hanging up and recalling the person.

Spotty Data Service. Almost nonexistant

I typically have 5 bars, however, I usually experience 1-2 drops during even the shortest phone conversation. I switched from T-Mobile a couple years back and I rather look on T-Mobile fondly these days. Once my ATT contract is over, I'm jumping ship.

I've had Sprint for over 10 years. It's the only carrier that works well in the three locales I need it to: Chicago, DC, and Green Bay / Door Co WI and all points between. My reception at home could be better (not good in the basement) but I've never dropped a call and I get five bars everywhere in Chicago and suburbs. No complaints. I tried Verizon last Fall and their cell service was good but their customer service was terrible and their rates exorbitant.

I get two bars near the window of my condo facing the lake, and no bars as I venture 12 feet away from the window. I wish I could use my phone. Definitely thinking of switching to Verizon.

I had to make some very important calls this evening and after drop call after drop call I had to drive a mile away to the local Jewel where magically the reception is great. I've had enough of AT&T and cancelling my account this week. Thankfully, my contact is over. Switching to T-Mobile or Sprint, but AT&T, you can suck it.

Dropped calls. Incoming calls go straight to voicemail and never ring. Cannot use data services unless pressed against my window. AT&T reps tell me straight out that the tower situation in my area is horrible, but the company does nothing about it. "Upgrades" and "new towers" have supposedly been in the works for over a year, but nothing has changed. I'm trying to figure out how to make the switch back to Verizon (which was great) without breaking the bank on broken contract fees, etc. I can't understand why I should have to pay for AT&T's refusal to invest in their network.

Ive had T-Mobile for years now. Reception is great. Calls rarely dropped. Ocasionally I will get a new phone and the reception varies due to the phone but Nokia and HTC phones seem to be ok. Customer service is good.

I have had US Cellular for 4 years and never had problems! I used to live near Irving Park and Sheridan and had so-so service with Verizon, then switched to US Cell and NEVER drop calls! I can even use my phone in my basement of my building, while my poor neighbors have to sit outside on the front porch to have a conversation. I can even use it on the EL... underground!

I was shot at and tried to call 911. AT&T says I have no network access. Horrible.

Terrible service. I submited a request to the BBB and lost. AT&T performed an in-house investigation which showed that I didn't drop any calls. I circled my billing statement which shows that I made calls to the same number within seconds of eachother on multiple occassions. I don't think this would appear on my bill as three seperate calls to one number for a duration of 1 second if I never dropped a call. I urge everyone in 60622 area code to file a complaint. At some point something has to be done. I terminated my contract and moved to Sprint. So far I do not have any complaints and can make phone calls anywhere in my condo. It's nice!

I live on the corner of Sheridan and Bryn Mawr and the reception is dreadful. Calls are dropped, VM are delivered late, phone doesn't ring yet a VM is left. Data access is a joke. Time to trade in and up. I hear T-Mobile has much better service...

Some days, one or two bars (of five), but on as many others "No Service" or zero bars, even which right next to any of three tall, street-level windows in separate rooms.

Pretty good phone reception at this intersection of Bridgeport.

What happened? I've had two years of great service until November '09. I can barely receive calls indoors, and only one to two bars when outside. The same goes for all my friends with Verizon Service. The Verizon employees at the Milwaukee Ave retail store acknowledge there is a major problem in the neighborhood but say it's out of their hands. Please fix the problem

The worst service I have ever had in my life. I've only had the service for a couple of months and I'm breaking the contract ASAP. Everytime I go to use the phone it says No Service or Searching. When people call me it goes directly to voicemail. My advice for anyone living in the city, DO NOT USE AT&T!
