The signal is inconsistant, going from 2 bars to no signal at same location.

AT&T is terrible in this area. I have had five phones and none of them have worked well. All last week AT&T dropped every call. I noticed that AT&T signal varies during the time of day. Afternoon is the worse. It seems that is when the tower usage is the heaviest. My cellphone does not work in my house. I have called AT&T many times and they just tell me to upgrade and pay twice the price with no guarantee it will solve the problem. Customer support is a joke. They read from a script. I don't believe they know how to think in resolving problems.

Many times calls go directly to voicemail without my phone even ringing. Standing outside or right next to the window usually increases by 1 or 2 bars, but 5 bars seems to be totally impossible. Callers are constantly asking me to repeat myself.

Rarely get dropped calls. 3G / EDGE

Only one or two bars. Calls get dropped all the times.

Good reception at all times. No dropped calls.

No 3G service, limited EDGE. Got to love AT&T.

Constantly dropped calls, Voicemail messages showing up an hour late... AT&T was better when it was Cingular, what a load of crap, dumping this Carrier for Verizon.

Inside the building no reception. Out side OK - 3 bars

Im on the 4th floor of my apt. but have never had dropped calls downstairs or anywhere else in the general area

I have almost no coverage at my house, inside or out! i drop calls constantly! my friends drop calls constantly at my house! AT&T cust support has done nothing in the 2 years I have been complaining.

fair coverage, but consistent dropped calls for no reason. the phone just goes quiet, doesn't even get a bad reception first.

Bad reception most times, no reception on peak times.. It's depressing to live in Silicon valley and not be able to make a call.. I happen to have both an ATT and a Verizon phone, Verizon is much better, but still many dropped calls. I'd rate that a 3

Since 30 October the reception has been poor; network busy message has become the norm. Text Messaging not working reliably. I will most likely move to Verizon, since with ATT, iCant depend on the network. Plus, Droid is looking very nice.

AT&T is lousy here - what else is new?

My service is great! I always have a good data speed and great service. My buddys iPhone drops calls all the time. He dropped a call next to the Apple building... HAHA! Verizon is the best!

It has been this ever since the edge network

Depending on where I am in my house I will usually have either 0, 1 or 2 bars. Sometimes the display will SHOW 4 bars but if I try to make calls or receive them, the bars go to 0-1 and the call will fail either immediately or within a few seconds after being placed / received. It's very sad up here in the foothills. All AT&T needs to do is put some repeaters or towers up here to solve a lot of problems.

The signals come and go. All radio frequency devices seem to be affected also. can't even use wireless home phones

I only get reception in one room of my house, and usually have to stand next to the window to avoid dropped calls, echo, and other problems. AT&T coverage around the silicon valley area seems terrible in general, particularly in the 3G band. I frequently receive voice mail for calls that never rang my phone, it sometimes takes 30 seconds or more to connect a call, and the call audio quality is absolutely terrible. I have to ask people to repeat themselves all the time due to audio drop outs or noise. Despite the terrible service, AT&T is overpriced when compared with other carriers. I love my iPhone, but have grown to loathe AT&T.
