My AT&T service has gone from bad to non-existent - or nearly so. I cannot talk on my phone unless I am in my backyard, and even then I am guaranteed a drop during every call. My 3GS service has also gone downhill and is spotty at best. Like many here I love my iPhone, but it's basically useless and I can't entertain the idea of signing another 2-year contract with AT&T and rewarding them for such poor service. Maybe Apple needs to lose a bunch of cutomers to wake it up. I'm switching to Verizon. Thanks for eveyone's comments. This site really helped me out.

Disaster. Two great phones, most of the time cannot even connect to make a call. Try getting voicemail. Forget about it. Wont connect after 10 tries. I have Verizon here for my work mobile. Works perfectly with an old Treo 700p. The calls on AT&T that do go through are of poor quality, and you can pretty much guarantee that you will have to redial (not necessarily with success) every two or three minutes. This is completely unacceptable. I cant believe Im letting myself get ripped off like this by these fools. AT&T - worst company ever.

AT&T is a joke. I live in SF, 3mn driving from the Castro (one of the main district of the city) and I have no reception whatsoever. One could think that I am one of the unlucky exceptions, but hold on: - From my place to the Safeway in Diamond Height (another area of the city, distance = ~ 1mile), there is no coverage whatsoever. - I work in Sausalito: no coverage at my work either - When I commute between SF and Sausalito (on US 101), calls drop ~5 times The iPhone itself is an excellent device, the poor quality of the network in one of the US major city is really what kills it. Basically, from anywhere I call (even when I have full bars), I consider myself lucky if my call goes through the first time. It usually takes 2 to 3. And this is with any phones I used on AT&T. I am from Europe when cell phone quality is excellent in most locations (including tunnels and metros). This is only a matter of AT&T spending its money on extending + upgrading its network rather than paying for prime time ads pretending they are the best carrier. "We cover 97% of American" (maybe if they don't move); "Our 3G is faster than Verizon" (but you need to be at the right place and not move).

I can only use my iphone if I lean out my kitchen window. A lot of money for little service. Not good. The iphone itself is fabulous with its many easy to use features, it's ability to sync with mac and other advantages, but the connection... there are no words to tell how really bad it has been.

I used to love my iPhone before I moved from the Peninsula to SF. Now, I can't receive or make a call and I go from 0 bars to 5 every few seconds. The phone is useless in my new home. Everything drops..internet, downloads and calls. I'm buying a droid, which is a shame because I think the iPhone is the most intuitive phone ever produced.

My data service is slow as molasses and often takes so long to load a page that it times out. There is NO 3G coverage. My phone is pretty much always on "Edge" which is 2G. So crappy. Also, my calls are always dropping. I'm going to suck up the termination fee and get Verizon. ATT is terrible and the customer service is awful too. No customer appreciation or concern.

AT&T service is extremely poor. You get service when the wind blows in the right direction and then poof its gone.

I only get reception in half my apt. and half my work by Levis plaza, sometimes less than that. AT&T sucks sooo much, why did Apple have to pick them. The day Verizon gets the Iphone i'm switching!

I have never been more dis-satisfied with a service provider than with AT&T. I have had their service since my first mobile phone and the last two years living in San Francisco Bay Area have been VERY UNPLEASANT on the mobile service. I can't finish a conversation (or even start one in many cases) because of the poor poor service quality around the city and throughout the region. I plan to switch this weekend asafp! (finally... it should have been done years ago.) I am only hoping the grass is greener on the other side, we will see.

I've never had a dropped call in the city, and get 3G almost everywhere. Maybe I'm living in a bubble, but AT&T has always been great for me!

I have had several people ask me to not call me from my cell phone because of how often calls get dropped in the city.

AT&T should be sued and Steve Jobs should be slapped for locking the iPhone community into this horrible provider. I have heard that AT&T has oversold their network. They cant handle all the iPhone users and can't handle all the traffic on their network. This is why they are dropping calls and often times when you try to place a call and the call fails it's because your battling other users for air time... .Love the iphone hate the AT&T service.

I just gave ATT a zero, but my friends have excellent coverage with verizon. To better help shoppers viewing the ratings, I am also ranking this service as I have experience with it through my co-workers. Verizon is great, no problems.

There needs to be a class action lawsuit on ATT. I get virtually no reception during the day and when I do, its EDGE or even at GPRS level. Thats why I gve it a 0, no 3G. Dismal. Sad and depressing. My co-workers with Verizon have no issues at all.

In the past 2.5 years, my reception has gone from bad to worse. Today, I have zero bars, "No Reception" or "Searching... " in the upper left corner of my iPhone 3GS. I rebooted it once just to make sure that it wasn't the phone itself. I love my iPhone but absolutely hate AT&T's coverage in this area. In contrast, my friend visits with his Sprint phone and has 3-4 bars and good reception. I'm in a condo building less than 500 feet from AT&T Park - yes their namesake. Wouldn't you think that they would make sure that they had great coverage around a major baseball park in their name?! Steve Jobs, please ink a deal with Verizon soon.

3G claims 5 bars. GSM claims 5 as well. But that itself doesn't match reality. inside building (about 30 ft from windows) incoming calls last for about 10 seconds until they terminate. same with outgoing. no data service.

I have never had a dropped a call in the city. I forgot that dropped calls exist. Verizon is expensive, but man, they have good coverage.

ZERO coverage in the entire Mission Dolores area. Love the iPhone but strongly considering jailbreaking it or moving over to a Palm Pixi on Sprint (I hate the Pre). I would love to move over to Verizon phone but I hate the Droid and the Crackberry.

Just moved 2 months ago from an area within the same zip code where I had consistent 5 bars to this area with TERRIBLE reception. Zero to 1 bar when propped next to a window inside my home, 2-3 bars when outside on the sidewalk. I put in a service ticket and was told T-Mobile has no plans in sight to put more towers in the area. The only option they give me is to get a wi-fi enabled phone, and then I have to add the $10 / month service to use that feature! 4 years as an excellent and loyal customer and now this? I'm shopping for a new service provider.

I am so frustrated with AT&T's dropped calls. drove between cole valley and teresita and had the call drop 9 times. Verizon here I come. AT&T should be forced out of the city for the sHeety coverage that they have been providing for years. I guess telephone deregulation really works. (sic)
