Anyone who lives in a big city knows that proximity to cell phone towers does not guarantee that you'll always have great service and no dropped calls. In fact, living in San Francisco, the saturation of 3G devices means that you don't always get perfect service, which is why the news that AT&T is rolling out its N-SET Solution, designed to reduce the strain on its 3G network and give everyone better service, is fantastic.
I experience the occasional dropped call, and know there are many places in the city where I can't get a single bar. A girlfriend of mine complains that she doesn't get service in her own apartment and plans to switch carriers because of that.
So, using Verizon's infamous tagline for good service, tell me — whoever your carrier is, do you get enough bars in enough places?
