I have excellent service with Nextel obviously it will drop calls quite frequently in some areas but other major carriers I've had have the same problem in most areas of the city. I'm not sure if it's 3G iDEN or not but the web sure is fast as hell and teathering for a computer works just fine. Sometimes on a low signal texts will send slow. But with iDEN it uses a data connection to send text messages so web doesn't go very fast without a strong signal so that's to be expected but overall great service. Loving Nextel!

Last several month, reception on this area went very bad. 4 out of 5 calls over 5 minutes talk, calls drop in the middle. What's worse is even with 2 bars up, phone doesn't ring and voice msg pops up hours later. I'm missing a lot of in-comming call without me knowing at all. Calling out is just like waiting at deli counter holding the number ticket. After pushing call button, you have to wait 20-30 sec. then finally it starts ringing or sometimes, "Call Failed" shows up. Once customer service said that a lot of people are using cell phone around me so lines are congested, but AT&T will KINDLY credit for that call (and I guess I should thank for such a kindly response ?) Hell I don't need your few cents back. I'm paying $100 every month for my phone because I need to Communicate RIGHT NOW otherwise I will send a post card.

Reception per se is not a problem - always 5 or 4 bars. But calls are dropped all the time, SMS do not go through, 3G is dead slow or nonexistant, etc. etc. The cell phone becomes practically useless, I am tempted to start looking for old good payphones...

Little to no reception in my house or even standing on my street. T-Mobile told me for weeks (since I got the phone) that it was a technical problem with my tower. Today they "slipped-up" and told me that a new tower needs to be installed to service my area. Very poor customer service.

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.

All over the place. I can be sitting at my desk (ground floor in front of unobstructed window) and watch the bars jump from 5 to 3 to No Service. I've noticed more and more dropped calls on this phone (never had this problem until about 3 months ago) throughout central San Francisco. When calling back, I now start the conversation with "Fewest dropped calls, my a**!"

Verizon does not have reception in the Hayes Valley of San Francisco.

1st floor inside wood frame building - poor reception - static when calls connect, dropped calls are common. May occaisonially (rarely) get 2 to 3 bars that go up and down even when not moving...

Very strange--on the 12th floor, I get full-scale or nearly full-scale reception, but there's a lot of interference, and sometimes there's no sound at all. No dropped calls, but it's very hard to use.

I have been hearing nightmares about other carriers. I have had Srpint for 5 years. I have ugraded my phone on every contract renewal date. Hate to say this in front of those having problems, but I have never, repeat never had a dropped call in 5 years. Reception is always available regardless of my location. Sprint has been and continues to be a great experience. Good luck.

My HTC HD2 is working great inside my office and have full bars. So please with it.

I get ZERO reception in my office on one of the busiest intersections in San Francisco. What a joke AT&T is! What kind of service is that? I have to WALK around the neighborhood in order to make a call on my cell phone. The CEO should be fired. How could a company be so horrible and still make so much money? I pay over $100 / month for this horrible service.

AT&T data rates in the BART tunnel from Embarcadero until signal is lost between Civic Center and 16th Street / Mission are incredibly slow; worse when there are crowds. That they finally put service in there is good but data rates remains awful. I try to use Nextbus to plan where to get off and which bus to take but often that's an exercise in futility with this network. I'm done with AT&T.

Inside the 5th floor of a building facing the intersection I mentioned. My desk is near a window, but my cell has no bars and no 3G. In some days, I get lucky with getting three bars and GPRS, but they don't last long. Frustrating.

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.

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.

I hate ATT for many reason, but get perfectly decent reception in most areas including the Canadian Rockies on vacation. I get 3-5 bars in my SOMA apartment even in the section that is below ground level. The fact is that the specific phone plays much of the issue, and the iPhone's reception SUCKS! All my friends who have one have issues, but those of us that stuck with older phones have little to no problem anywhere. Of course I did have bad reception around Kanab Utah, but look it up on a map and you'll understand why. No problem in Page, Grand Canyon, Flagstaff, Sedona or Phoenix areas.

Since the SOMAGrand and first Trinity Apt. Tower went up, AT&T reception has diminished considerably. Both Palm Treo 650 and new iPhone 3GS reception are awful. Am considering a booster for the building. The Clear Voice 800 or jdteck devices. They run about $200 - $300. Anyone have experience with these?

I work on the corner of Mission and 13th and the AT&T reception is horrible! Everyone at my office complains about how their AT&T phone don't work at all in theis building. And outside, I can only get edge at best for data speed!

the iPHONE 3GS has been a big disappointment. For all the money we pay per month it's not worth it. It drops calls all over the place especially at home in Emeryville. No reception. It switches between Edge and 3G while I'm in the same spot. ATT and APPLE owe us money back!
