My iphone jumps back and forth from "searching" to 5 bars while I'm in my apartment. If I am on a call, it drops within a couple minutes without fail. Very frustrating! I know all the service gaps along the Red line and I'm not talking about the lack of 3G, but COMPLETE dead zones, no service. Some of the dead zones include just North of the Sheridan station and just South of Fullerton. I'm just about at the point the horrible service is just not worth having an iphone. I miss my old Verizon service more each day.

Very poor reception, both inside and out of my apartment. Thankfully my contract is done at the end of January. Love my iPhone, but the constant dropped calls and texting failures mean bye bye.

In both downtown Chicago and in the South Loop, AT&T reception is very poor. I received two voicemails this evening at 7:00 that had been sent this morning. I expect poor reception at times--I live in a very busy part of the city, near a highway and train stations. I expect that there will be times when usage will exceed the tower availability. But I expect those times to be an exception--during a Bears game, say, or the Fourth of July. Poor coverage here is a near-constant. My previous contract was with Cingular, and before that T-Mobile. Never had a problem with either until AT&T took over Cingular. My two year contract is up this month, and I'm seriously looking over either Verizon (never used) or T-Mobile again.

I have been considering swithing to AT&T for the sake of and I phone but am hesitant to leave Verizon. I have never had a problem with reception unless I was in a lower level or an elevator- otherwise very reliable and highly recommend.

AT&T really stinks in Chicago. There is no signal at Broadway and Hollywood (right off Lake Shore Drive). What is with AT&T's crappy service? Verizon has it right!

I have lived in my apartment for a year and the entire time I've lived there I've rarely had a phone conversation that did not drop the call at some point. It's incredibly frustrating. I have to sit next to a kitchen window for reception and if I move, consider the call dropped.

While AT&T struggles to bring solid 3G coverage in Chicago, Sprint launches 4G and now reports show that T-Mobile is rolling out their 7.2 Mbps HSPA network in Chicago. Come on AT&T.

I've had T-Mobile for almost 4 years now and am fed up. Have a Motorola Razr as our 'home phone' and that's not reliable either. Often don't even get the incoming call (even with 3-4 bars) and a voice mail shows up 5 min later. Frustrating when you're expecting a call. I wonder how many calls I've missed when the caller doesn't leave a VM. Phone always goes dead around the Merchandise Mart on the brown line. We live in a house in Lincoln Square and coverage is terrible in the back. Okay outside but that's annoying. Even with pretty cool phones and cheap prices, I want reliability which TMobile doesn't deliver.

It's amazing as Sprint launches 4G in Chicago... AT&T continues to struggle with 3G in the city. I guess what they say... don't trust a wireless provider with Telegraph still in their name. ;-)

Awful reception in my condo. It works only near the windows and drops out half the time.

i think once every two months I get a "network busy" thing, I wait a minute or so and its ok. somtimes I may lose a call going past forest preserves. T-Mobile and Verizon have been the best reception for me. My contract has been up for like a year waiting for ATT to get their network together so I can get an iphone. looks like that isnt happening anytime soon so tmoblie will get another two year contract from me, mortorola cliq pre orderd!

Reception is awful - calls frequently drop and even the ones that stay connected sound as though I am sitting inside a tin can with cotton stuffed in my mouth. And forget about high speed data transfer!

No complaints... .only time I lose coverage is when I am underground in the EL. But that is expected.

never had any problems since '99 and now its 3g! Windows Mobile with High Speed is soooo much better than any iphone could try to be- no dropped calls, even works in subways, and I get high speed streaming video, email, or what ever I want

I often have dropped calls and my phone even loses coverage entirely with a "Searching... " message. AT&T says several towers in my area are "degraded" and will be fixed soon, but this has been the story for over a year.

i am thinking of taking the hit for exiting out of my contract early. terrible reception. from 2 bars to 0 by the time I press talk. good news is that I am able to live a cell phone free life.

My reception varies from moment to moment from 0 bars to 4 bars. It constantly changes. If I watch it just goes up and down as I am on the phone. I am lucky if I can complete a call without the line being dropped. I am so frustrated. I called 611 and they looked into it but they were not able to do anything about it. I had excellent reception when I lived in Lake County in Illinois but it has only been bad while living in Chicago. I want to know which carrier is best in my area.

AT&T is awful! Dropping client calls is not good for business. I'm switching to Sprint for the Palm Pre. The iphone shine has faded.

Data speeds are awful, and 3G is inconsistent, cutting in and out. When 3G is switched off, EDGE sometimes performs OK, but sometimes I can't get any data access. Really, this is shameful performance. Dropped calls happen regularly, too.

My phone shows that I have full serivce but I never get texts on time and it takes about 5 or 6 tries to send an outgoing text... .is it a fact that you can drop your contract without any fees?!?!?! screw you att
