I do not recieve 99% of my calls when I am at home and about 75% of my calls I do not recieve when I'm in other areas of Oakland and San Francisco. AT&T was a nightmare to deal with.

T-Mobile often has poor reception in Oakland and at SF State, where I go to school.

Terrible coverage here. I am in and out on every call.

Inside of my old house, I get no reception. My friend who is visiting with an AT&T phone gets great reception.

It seems weird to be able to see across the Bay, including all of Eastern San Francisco, and still get little or no reception. I don't know how that's even possible! Reception in this area in very spotty, and calls are often dropped. Also, when I tried to use the phone in San Francisco, I couldn't complete a call -- yet people all around me were chatting away on their cells! Very frustrating.

Good reception outside of my house on deck. On the street calls are mostly lost, phone doesn't ring 90% of the time. I've tried Cingular, Verizon, and AT&T, none work very well.

I have a Nokia hand phone bought in Asia, so the GSM band is 900 / 1800 / 1900. With AT&T and Cingular sharing the same network now, I get reception almost everywhere. Very few dropped calls. It must be because of the upcoming merger. We will see if it stays that way.

Driving to Oakland Coliseum from 580 on Edwards Ave., and lost all reception until Edwards & McArthur Blvd.

AT&T is the worst coverage you've ever seen. And, confirming the other people who have posted here, the wireless radio in my my palm phone constantly turns itself off as the network struggles to connect. I would not recommend AT&T to anyone. If you must have GSM, I think T-Mobile is the least bad option for the Bay Area.

Horrible reception at home and in the area. Reception varies from no bars to two bars. It sometimes have to hold phone near window or hold it up in air. Calls frequently dropped. I would not recommend them.
