AT&T is horrible. My phone didn't ring when people call or register that I had voicemail until days after the call. When the phone did ring, I had a one-minute countdown until the reception went out and the person on the other end couldn't hear me. I use my cell phone as my primary phone to talk to clients; less than one month after buying the iPhone and starting a 2 year contract with AT&T, I had to cancel my plan (and they won't waive the cancellation fee just because of a silly thing like your phone not being capable of being used as a phone) and get a Verizon phone.

I have been with Sprint for 10 years now and I have never had any problems with reception anywhere. No dropped calls (I don't even know what it is), always full signal and I do move around in and out of different buildings in Manhattan when I go to see my clients. I definitely recommend Sprint fo everyone. Their customer service is wonderful, very kind and patient people... It's a pity though, that they do not have lower radiation phones - but then- who does?? I hope this problem will be solved in the future - nowadays Sprint has such great cell towers coverage that they can easity launch some new phones with lower SAR.

Near spotless coverage in my apartment building on the T-Mobile network, even on the lower floors, even in the elevators. Alternately, the lower floors (and my apartment, for sure) are known to be dead zones for phones running on the AT&T network. T-Mobile wins, in this case.

No reception at all for voice calling on the 3rd floor of 10 W. 15th Street. EDGE (data) requests succeed sporadically, but definitely are not instantaneous. My other cellphone is a Motorola RAZR on the T-Mobile network. It gets 5 bars in the exact same location as my Blackberry 8310 on the AT&T network. Friends with iPhones (on AT&T) were unable to place or receive phone calls or texts from my apartment. There is definitely an AT&T dead zone where I live.

As of late, AT&T cell coverage has become terrible. E.g. long delays in transmitting text messages, dropped calls, loss of service. I'm curious if this is a homeland security issue in Manhattan affecting all carriers or if AT&T is just farming out its duties to subcontractors.

2 bars to 0 bars indoors. I pray never to receive or have to make a call in this area knowing it will be dropped or have spotty reception. 2g is almost as bad as 3g in this area.

I get no reception in the entire office building.

This might be temporary as I have had reception here in the past, but now there is no reception between Spring St. and Houston St. on the west side of 6th Ave.

Ever since I switch from T-Mobile which was horrible to say the least. I haven't had anything but stellar service with At&t. My gf had Verizon and there wasn't one place in the city / long island or upstate that she got service and I didn't, love AT&T I do get dropped calls sometimes but 3G works great for me 90% of the time. Most people that have bad reception with AT&T and iphone are the same ones that refuse to update their phones or are just exaggerating about how they lose service. because I have been in many places with people with sprint / verizon / T-Mobile and with AT&T I always have service longer than any other carrier.

I just switched to T-mobile, and I have no service at all in Grand Central Terminal, New York. Can't believe it.

Great in building reception most of the time.

Reception is horrible all over tri-state area. Dropped calls, no service, horrible voice quality. Sounds like a cell phone from 10+ years ago if you can get a signal. DREADFUL

We recently moved from Chicago to Manhattan. AT&T service had been mostly reliable in Chicago, but is terrible in Manhattan. On street in front of our building, 'no service'. In various area on the streets, calls go directly to voice mail, and outgoing calls are impossible even when bars are strong. AT&T's network in Manhattan is in bad need of repair or upgrade. If it weren't for my beloved iPhone, I'd drop AT&T immediately.

the only place I've lost cell reception is on the NE corner of 40th St.and 5th Ave. (across from the NY Public Library). Step off the curb, and the reception is fine again.

Verizon's signal fades in and out, and there is no consistency. Very high probability of call being dropped. Battery dies pretty quickly.

I cant not tell how HORRIBLE AT&T is here! My calls are ALWAYS dropped! The sound is UNREAL and the call quality is the worse! I switched my business of 185 to Verizon Wierless yesterday. We all have BlackBerry Tours, and Verizon has a wonderful network! The sounds are clear and data is fast! VERY happy I made the switch!

ABSOLUTELY NO RECEPTION in the Helmsley Building. This is ridiculous. Grand Central Terminal is directly across the street. And forget about data, my iPhone is constantly dying because it is always "Searching" for service. This is the worse service I have ever paid for.

Phone says 3-4 bars, but drops calls repeatedly. Could be the UN, but Verizon users don't seem to have the same problem.

3g Service in Union Square NYC is non existing. I had a Nokia N75 and I thought my problem was the old handset (well thats what the AT&T store reps said trying to make me renew my contract ). Now that I have the iphone 3gs I get the same problem. I spoke with a rep at the AT&T store on 14th street and he told me to switch to EDGE for a week. I spoke to numerous reps over the phone and they said it seems to be faulty 3g cell towers in the area being worked on. I say we all should complain and get a class action lawsuit going on and get some money back or get AT&T to change the rates for 3G service... ..

Verizon works nearly everywhere I go in Manhattan. Only problem spots are my office desk next to a window (2 feet away works great) and in one elevator as it hits the second floor. The other two elevators have no problem.
