When I signed for this plan with Cingular, I had never thought that a big and established company like Cingular would have so poor call quality. I keep getting dropped calls almost constantly and this is not a remote problem. I have friends who have cingular and everybody complains about the same. Called their customer support but they never admitted that Cingular network has this problem. Changed my phones 2-3 times hoping it to be a phone problem and not a network problem. Nothing worked. Now I am desperately waiting for my contract with these guys to get over and go to some other company.
