AT&T

AT&T provides the worst coverage, call quality and service of all the carriers.

most calls drop or inaudible. Other AT#T phones have same problem, 4G smart phones better but below average. I'm in middle of city and one bar doesn't work.

The voice service gets 2 bars on iPhone. The data service is dead. I was unable to check e-mail or weather.

Phone reception is good. Rarely do I drop calls although 3G speed is slow and 4G is nonexistent.

In general AT&T reception is VERY spotty anywhere in Berkeley, but haven't found any other carrier to be any better

AT&T signal on my iPhone 4 seem to be pretty good here. I am actually looking for more reviewers to gauge if moving to Sprint will be OK in Mission Area of San Francisco.

All over Oakland Hills / Piedmont and into SF, very consistent, clear coverage with very fast data speeds.

Typically 3-5 bars some indoor locations are down to 1 or 2, but very rarely drop calls. Signal seems to be good through most of North Mission, Civic Center, SOMA. However we are soon to be moving to Valencia and 25th (94110) where it seems like a very different story... Will post info from there soon.

I always have between 3 and 4 bars in my apartment. 3G is sometimes quite slow however.
