Aweful reception. If I do get one bar it usually drops my call eventually. Can only stand in one place in my apartment.

Very disappointed with AT&T's coverage in SF Bay area. It is shoddy at best. I go from full coverage bars to zero coverage bars at the drop of a dime, and my calls are frequently dropped.

Bad... ... ... ... ... ... ... ... ... ... ... ... ... ... ..voice is so distorted you can barely hear what their saying.

Sprint has pretty good reception in most places around the city, especially in Downtown (mostly 4 or 5 bars). Few low reception spots, overall where I use it, it works great.

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.
