T-Mobile data plans are some what of a value but the network sucks and reception has been terrible lately, I'm really considering Verizon but they are more expensive.on a scale from one to ten I give T-Mobile a 4 and I'm being generous.

Seriously, God forbid I ever have to call 911 and hold a call! AT&T is absolutely wretched, though, everywhere I go, so I should be used to it by now. Definitely getting rid of them soon! It's always something with them..

No reception in my building. No reception within ogilvie train station. 15-20 min away from the city I can finally start getting SMS and phone calls. Very frustrated since most of the day I am out of reach. The interesting part that my work blackberry which is supported by AT&T has reception all day... Plan on going to AT&T store to ask for trouble shooting, hope it will help.

Awful. Phone varies between 0 and 1 bar. Calls cut in and out on both ends and calls constantly dropped. Had this phone and plan for about 1 1 / 2 years. No improvement during that time, despite refreshing cell tower connection frequently.

Riding the commuter train home, I thought it was a good idea to have a smart phone for the ride. The problem is that you have to get 10 minutes outside the city before you can use it. Bars don't matter. I've had 4 or 5 bars from AT&T and still can't get any data - just times out. I'm sure AT&T would say it's because there's a "spike" of usage around 5-6pm downtown at the train station and that they can't accomodate for the spike in usage, but I would submit that a "spike" that happens at the same time every day is really just something you should be able to plan for. It's sad that a "contract" can lock you into a company that can't delivery on their side of the contract. I think I may just pay the fee and get out.

I'm amazed how bad AT&T sucks in downtown Chicago. I have a signal, data just won't connect. It times out and I get absolutely no data. I've had to resort to using my Verizon 4G MiFi just to get data on my AT&T iPhone. When AT&T can't provide data, Verizon has full 4G speeds at over 10m+! AT&T, you suck! Avoid AT&T if you live and work in downtown Chicago. It's useless for business.

Horrible Connection constantly!. I can get reception most of the time when I am not holding it, but as soon as I hold my phone, it will lose connection within ten seconds. And this happens almost anywhere in the city. I've lived in Atlanta and Oklahoma before this last year and never had problems with iphone / att reception nearly this bad.

I live in North Center and work in East Lakeview. I can never get a signal whenever there's a ballgame or a parade or a street festival or anything going on. I can't even send or receive text messages. I often fail to connect to the 3G. throughout Chicago. The one thing I really like about the service is all the AT&T hotspots, though I wish it were easier to connect to the internet without wi-fi. I always joke that my phone is wi-fi only. Anyway, I just canceled my service. Not sure where I'm going next.

Well, in addition to the crappy cell service, for the past 3 days, I have been having problems with text messages not going through. This just started. No changes to my phone. Just another reason to hate AT&T.

I like this company because I get a perfect signal on my phone even if I am in the basement it has at least 4 bars unlike T-Mobile they drop so many calls I'm glad I switched to AT&T

Lousy reception in or out of the house. Has been like this for a couple of years, This whole area is bad. I don't understand why Verizon doesn't put up more cell sites, there is plenty of room on the CSX railroad right of way or in the 2 large parks nearby.

I live on the first floor of a 6-unit buiding. I Have had my phone for two weeks, and have never had more than 2 bars of reception. I have constantly dropped calls, and had internet downloads fail repeatedly. I had the same problem with AT&T, and with Net10.

The reception issues just keep getting worse. I often drop calls on the street in the loop, and almost anywhere else in the city. I'm trying to decide between between Verizon or Sprint. I will never give AT&T another dollar.

Service was reasonably good until introduction of iphone. Now horrible or no service at all.

On the 13th floor south facing side of a high rise. 4G LTE Signal ranges from 4 bars to full strength.

On the 13th floor south facing side of a high rise. Manual roam on US cellular: full strength.

awful

horrible reception. All calls inside my home and most buildings are dropped. At most I get 2-3 bars when outside or in my car.

ATT is horrible! I used to have Sprint which was excellent service and switched to ATT. What a mistake! I have continuous dropped calls and it's very annoying. There are 2 phones on our plan and our lives are spent on the phone with ATT. We get answers that the towers are down, our phones have a problem, we need to hook up to Itunes and update them,we have to talk tech support and then they have us on the computer and checking bars on phone, etc. If you have these problems, you can get a micro cell tower for free. But, guess what?? It doesn't do a thing. Whereas, Sprint NEVER dropped a call, works in the elevators EVERYWHERE, even at the main post office elevator and people would look like it was unbelievable. In fact the ATT rep that came to our residence couldn't use his ATTphone. What did he use to call ATT?? The SPRINT network with his personal cell phone. What does that tell you? Like another comment, we stay on the phone but get "free" service. It is worth it?? NO! for all the annoyance of dropped calls and the time we are on the phone with them. The next step is the FCC. Then switching back to Sprint!
