I tried Alltel for a long weekend. In Green County Alltel has 3 towers. USCC has 7 and 3 more in the immediate area. I was told that Alltel would work off of the USCC towers. Problem is that the phone kept picking up Alltel's signal first (as it is supposed to) and the phone wouldn't pick up the USCC towers even though I was sitting there staring straight up at it. Phone kept bouncing back and forth from Alltel 1 bar of service or none at all to analog and back and forth and so on and then picked up someone else's tower (I think Verizon) and then back again and never picked up USCC unless there was nothing else available. Phone couldn't decide what it wanted to do at all. I tried to force cdma only, and switch it to home/a or home/b and nothing would work right. I couldn't even get the phone to connect on a call unless I had full service. Phone was LG VX5450 camera phone. Nice phone, but service was completely unacceptable to me after I had been spoiled by USCC's rock solid coverage with no switching back and forth.
