AT&T reception sucks. I can't use my cell in my apt and am therefore paying tons of money for long distance on my landline. Calls constantly get dropped all over the city. From what I read here, Verizon is the way to go. Goodbye, AT&T!

100% 3G coverage.

Very limited reception in my house

I've been a long time customer of ATT and I had excellent service when I lived in the East Bay. However, I recently moved to San Francisco and its terrible! Reception is very erratic, I consistently have dropped calls, and call quality is very poor. I even tried changing my phone and it didn't make a difference. Many of my friends have Verizon and have perfect signal; as soon as my contract is over, I'm switching.

overall good reception in the upper noe valley.

OOPS: in error and in my frustration from dealing with ATT, I accidentally listed my first post as Alltel, which is incorrect. I have ATT. The WORST SERVICE EVER. I have spotty coverage, the phone switches between 3G, Edge and G and I constantly drop calls... inside and even outside! I can walk 2 blocks up to Market and get a perfect 3G signal, and walk 2 blocks to Valencia and get a perfect Edge signal (even though the service is still spotty-at least it is consistent). However, in Dolores Mission... weak coverage. Per ATT Tech support, it is a weak coverage area and they plan to build a tower at 16th and Guerrero... but no idea when. My roommate has Sprint and can talk in the basement. I on the other hand, standing in the bay window or walking down the street, can watch my signal go from full bars to 1 bar and so on and so on. Their techinal support is lacking also and from other posts on here, see I am not the only one. I am going to Sprint.

i used to get 1 - 3 bars, now it's more like 0-1 bar. ATT says that they used to be leasing a tower from T-Mobile here but are no longer in that agreement. they want to fix the problem, but have no plan in action to fix it. they're willing to let me out of my contract, but i'm not sure what other carriers have better service in the area and can take my iphone, assuming that I unlock it myself. also, not sure what happens to my iphone warranty / apple care as a result.

overall service is excellent, especially compared to competitors (ATT, T-Mobile in particular)... too bad the Iphone doesn't work on CDMA networks! I will have some distortion on some calls but usually because of trees / foliage. EVDO is decent too. I'd recommend Sprint if you are in San Francisco. Verizon is #2.

I recently switched from Sprint to get an iphone. ATT / Cingular is horrible in SF compared to Sprint. I got 1 bar on my iphone for the first 3 months and then last month go "no service" at all. I love the phone so much I am in denial about my non-phone use. ATT tech department says they have a known problem in that area and have no resolution date. I am not the only ATT customer in that area that is having problems. I guess they really have no love for us... Love the iphone, ATT is horrible.
