Yeah but they don't offer that information freely, so you have to do some digging to find out. In fact, they steer you away from finding that out. Oh, and you pay for the privelege too.
In the past month I have been with Sprint (8 years with them), Verizon, and Cingular. Sprint couldn't care less anymore about their customers. Sunny indifference, is how I would describe their attitude. I spent $450 to get out of my contracts with them. They still don't even know I'm gone. When I first went with them years ago they bent over backwards to help you out.
Verizon has great coverage in our area, no dropped calls that my family or I have experienced. But NO EXTENDED NIGHTS AND WEEKENDS. This wasn't good for us. They cheerfully refunded my money including the activation fees, but only after I went back to the store to complain about the $977.25 bill the company had sent me. I stayed with them 4 days.
Then I went to Cingular and have been with them about 22 days. We have three different phones (Sony Ericsson, LG, and Nokia). ALL OF THEM make the TVs and speakers buzz. Since all three do it I would have to guess IT HAS SOMETHING TO DO WITH CINGULAR'S SIGNAL.
By the way, we can't live with Cingular's bad signal strength and dropped calls. Terrible in our area. All my friends who had ATT loved their service and say that it is much worse now. Also they all comment that it has been worse since the beginning of this year. No body seems to know why. It doesn't make much sense if it is the same service, same towers.
The cell phone is our business phone. We can't afford to have repeated dropped calls. I guess we will go back to Verizon, though I'm not thrilled.
In terms of signal strength and dependability in San Antonio, TX and the surrounding area, Verizon is best, followed by Sprint and, a sad last, Cingular.
Maybe I should try T-Mobile. Any one have any experience with T-mobile in the SA area and up I H 10 through the Hill Country?
