AT&T Wireless (GSM)

I go to school at Encinal High and that's right near Alameda's old Navy base. With Sprint I get no signal whatsoever, but with AT&T GSM America I get at least 3 bars. AT&T is awesome!

Usually don't have any problems with Sprint in the city.

I get no reception inside of my condo. There is reception outside by nothing inside my unit. This is ridiculous. Time to cancel.

Poor to No Reception at my house. It usually gets a little better as I walk from my house towards Solano, but its still unacceptable reception for a flat, well populated area with essentially no obstructions and no buildings higher than two stories. I've complained several times, but, of course, that doesn't do any good. Contract is up in December at which point I'll find a better carrier.

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.

Get a wireless hands free set and leave in the 3 foot radius that is getting good reception then, you can walk around your house.

I have Sprint PCS. Get very good signal in Albany, all over San Francisco, all along I-80, and even while up on the North Lake Tahoe ski slopes. I do, however, get only 1 bar at work in my office building in Hercules (although it's fine when I go outside or next to a window). I have friends that use Verizon and AT&T that I go traveling with frequently, and I always get the best signal among us. I'm always lending my phone to them to make quick calls. I've had two Sanyos (SCP-8100 and SCP-6200) for Sprint that always worked very well and got very good signal. I haven't had any other phones, so I can't really compare them.

Very poor reception inside my house and indoors in general.

Signal is quite low and below average in some industrial areas in Berkeley. Specially in several buildings there is no reception inside. Though works great in Newark, Union City with good reception.

I think this is a black hole. I've never heard of anyone getting reception here. I'm not even roaming or on an extended network. No service, period.
