Ok, I know this has proably been done before. But really which company IS THE BEST for voice quality? I'm guessing the best voice quality is between Cingular and Verizon? I'm going to be using the cell phone in Southern California, so which provides provides the best coverage (and call quality) overall in So-cal? (Los Angeles and Orange County areas) Like when I talk to someone on the phone, I want it to be CRISP and CLEAR as possible. (and only going to be using phone in the two areas mentioned above). I noticed that when I use sprint to talk to someone, it sounds okay, but when I tried using someones Cingular phone it actually made the person sound more clearer and crisp than my sprint phone. Does cingular have the best voice quality in southern cali? I tried looking at the different provider maps, and by the coverage maps it seems like Nextel has the best coverage in two areas I mentioned above. But does having more towers in the area mean better voice quality, or just better reception? Also does anyone know how accurate this site is: http://www.cellreception.com/towers/ I did the tower search, and it seems like nextel has the most towers around this area, and also ones closest too my work, etc. Nextel has 2 towers in the same city, and another tower in the next city over. So perhaps that's the best choice, assuming that site is accurate in the tower placement. But I don't know, does Nextel has the best call quality? I don't talk on the phone much, hardly ever, but when I do I want to sound really crisp and clear to the person I'm talking to! Also how does call quality work? Like, if the person sounds really crisp and clear to me, is that due to MY cell phone network having good voice quality, or is that due to the OTHER person's network having good voice quality?
