I reported that there is no reception at Baker and Fulton on Oct 25, 2007. Nothing has improved. 3 months ago, I called T-Mobile from work and filed a support ticket. No action has been taken. The phone works fine elsewhere. No reception for 5 continuous months is reason to cancel the contract. T-Mobile claims, and my phone's network settings verify that AT&T (Cingular) runs the towers in my neighborhood. T-Mobile claims that they lease Cingular's tower. Seems like they haven't their lease in about 5 months. DON'T USE T-MOBILE. Their coverage map is a lie.

Occ dropped calls, but really fairly good throughout the city, also good at some ski mountains at Lake Tahoe

AT&T coverage is the pits in Diamond Heights. Standing in the Safeway shopping center is hit or miss. Garbled reception and poor quality all the way around. AT&T should be payng me for this service. Frequent drop outs all over the city. And yes I can seldom get good quality calls on the top floor of my complex. Cingular used to be better. And it's not just the Razr phones we own. It's the technology that AT&T is using (abusing) and passing off as a paid service. Jeez!

Virtually no or fleeting reception. Calls get dropped constantly. Totally unreliable.

Service in my apartment (Castro and Cesar Chavez) sucks. Only two rooms that even have a chance, and these still frequently drop. Usually have to stand in one spot near window where bars fluctuate rapidly between one and three, and not move at all. Have to go outside for important or uninterrupted phone calls. Also basically no service for a few blocks on Diamond Heights. Had the phone "updated" but this helped not at all. Most of the rest of Noe Valley and the city are usually okay, but reception is often bad, so that I have to ask people to repeat themselves.

T-Mobile reception INSIDE is nothing. Its no reception, T-Mobile REFUSES to let people out of contracts because of this. You can not get service in ANY stores either. One must go on street and walk 1 block before coverage is aquired again.

I'm not sure if it's just T-Mobile is bad in SF or what, but I get horrible or no signal at all in my office.. I have to use my land line for everything.. it's terribly frustrating. Seems like SF in general might be very bad with cell reception.. for a large city like this I would think the wirless carriers would strengthen and increase coverage... but it would not appear to be the case.

Inside my house, I need to stand by the window in the back of the second floor, and even then it's spotty. It used to be better before Cingular merged with AT&T and forced us to upgrade with new sim cards. I know that my son's girlfriend gets reception in our house, but that's Verizon plus a relatively newer phone. Can't tell if it's a better carrier, phone, or both.

Up at the top of the hill on the west side. Reception is really bad on the east side of my condo, and slightly better on the west. I drop calls about 50% of the time. The only thing that seams to work is to stand on the back deck and not move (west facing deck). Then there are just periods of incomprehension rather than altogether disconnecting. I'd switch carriers in a heartbeat if there was one that worked better.

Despite having 270-degree views for miles, we have never had any cell reception here for the past 11 years.
