Sitting high on top of the hill and still reception is terrible. Sometimes get 2 bars, sometimes 4. Calls drop or we don't even hear them ring. Looking to go with Verizon possibly

I get horrible reception in my area. I switched from T-Mobile to Verizon and have regretted it ever since. I have trouble receiving and dialing calls. I drop calls ALL the time. When I called Verizon multiple times, they sent me an ENVY2 replacement phone three times. I'm on my 4th phone and am still having problems. Apparently there aren't enough towers in my area, but there will be in a year! Other people who have Verizon and visit my place also do not have reception, but AT&T phones have full reception and no problems. Service is ridiculous. I've called customer service and was told I would receive a call back; it never happened. Needless to say I am very angry and frustrated with Verizon's service. There's a signal booster that could possibly help that I would have to pay $200 out of pocket for - ridiculous! The company that claims that have the best service should pay for the instrument that would keep them to their contract. They are letting me out of my contract - hallelujah!

Data and voice signal strength in this area is abysmal and has gotten worse in the past week. I can barely get an Edge data connection in the Diamond Heights Safeway area or my home a block away. A few months ago signal strength was better - not great, just better than it is now. I could get 3G connections that would last a while.

AT&T sells services they cannot provide. It is fraud and there should be a class action lawsuit against them. Forget about making phone calls through AT&T in SF! G3, G4 downgrade to G1... it doesn't matter you will not be able to make or receive calls within an 8 mile radius of the downtown SF Apple Store where I was told to get another phone if I needed to make phone calls! And they didn't mean with AT&T!

The last month my ATT Service has gone down hill, I basically told them to stuff the $500 a month bill down their throats if it did not improve, so the ATT store gave me a new Iphone 4 to see if the reception was better at my office. No such Luck, called them and asked what I should do and they said as of Aug 15 and Aug 17 there are two towers out in the area. Truth or a Lie? Every time I call and ask why my service sucks they say there are towers down. I asked when can I return my phones and cancel my account they said it would be fixed by Friday, another lie. I asked them so since I am getting partial service maybe I should pay part of my bill. Silence, I mentioned if this was a car and every week it did not work, there is a law I can return it, silence. I asked if I am getting progressively worst service from ATT then I want to cancel may service, she mentioned if the towers are not working then we could talk about that at a later date. BS I say. Apples biggest mistake was going with ATT... T-Mobile sucks in SF but its better than ATT service.

5 bars and no reception. How does that work exactly?

If i'm lucky, i'll get one or two bars of reception on campus. This is the one place where I need a phone to work ALL the time for me, but it doesn't. Even my ATT phone had very crappy reception. Only T-Mobile and Verizon had reception that was good.

I've been working around here for about a month now. I can receive calls for the most part, but sometimes my reception is terrible and I miss calls. Txt messages go through regardless. Sometimes it takes a minute for service to kick in. Overall the phone is a problem in itself. Add the reception issue and this experience becomes irritating enough to consider swictching coverage.

SAD sad sad... no cell phone reception in this area.

The AT&T reception is so unrelieable as to be completely unusable in my appartment. I would be better off with two tin cans and a piece of string. I cannot maintain a conversation for more than five minutes without dropping a call. Many times I make calls it fails without connecting. This is with the iPhone 3G, iPhone 4 and other phones I have tried. Seriously I am going to have to switch to a landline or use Skype for my calls - how lame is that? If you live in San Francisco avoid AT&T like the plague. Until they can put some new towers in the service is completely unusable.

Safeway in Diamond Heights is an AT&T cell phone dead zone. Calls elsewhere in the neighborhood are a gamble--sometimes I get a signal, other times I don't. When I do get a signal, the call sometimes drops. My roommate has T-Mobile. He has no problems in the same area.

In the SF financial district, you will see 4-5 bars on 3G with the iPhone, but cannot make or receive a phone call, cannot access voicemail, cannot get texts, cannot use Internet. They like to blame the buildings, or "hills of SF", but after 7pm, I can use all voice and data functions on the iPhone as expected. Sitting at my desk I can confirm that I cannot get voice or data connection during normal work hours, then after hours my iPhone can be used for voice and data.

Good phone, 3G and satellite location all over Forest Hill. Satellite along Lincoln Ave (at least 5th to 19th) doesn't connect.

I'm an AT&T refugee. Got the Droid on Verizon because I couldn't wait around for iPhone any longer. I and the people I phone have been super happy ever since! Phone calls are crystal clear and no more dropped calls, while not moving at all. I now can move around my place while I'm on the phone without worrying about dropping a call or scratchy call quality. I usually fluctuate between 3-5 bars but 3 is sporadic, not the norm. With AT&T, I was lucky to get any bars unless I stood in one 2 ft area indoors. 3G has been consistent too. The system goes to the slower 1x really late at night but that's when I lose bars too. Not sure what that's all about. The apps aren't as diverse or extensive as Apple's but I don't care because I can receive, place and maintain phone calls at all times. It's supposed to be a phone after all, right?

I have fairly good reception in my apartment at this location. At least it's usable. The weird thing about AT&T reception in San Francisco is that it is unpredictable. There are lots of dead spots, especially in the Financial District. The 3G reception is particularly unpredictable. In the Financial District, you are lucky if you get 1.0 Mbps download. Usually, it's 0.5 Mbps. But, I was in South of Market, at Harrison and 6th St.the other day, and there I was getting about 2.0 Mbps.

My phone is practically useless in my Telegraph Hill apartment. Upon the rare occasion when I am able to call out or receive calls, they invariably drop off. Absolutely pathetic coverage by Verizon.

I never get reception in my basement. Friends come over and can make calls, get calls, etc. My T-Mobile phone is so bad. I have to walk about 300 feet from my house before reception kicks in. I will never buy anything T-Mobile ever again.

there's no reception in my apt. I've just moved in and found no reception at all. T-Mobile said I need to wait 5 business days to get perfect reception, but it's all lie. They never do and can't do. I found my manager's AT&T phone is working well. Just spent a stuid week by stupid lying service with t mobile.

Consistently no reception within the Presidio around the Washington Blvd.area. Occasionally I can send or receive a text at home, but calls are impossible unless I leave the Presidio to the south or walk about a half mile north.

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.
