Cingular GSM (T616) Chicago getting ready for my T600. I have Wireless Internet Express. My GPRS works, but I can't get CSD to work for nothing. I have checked my bill and it should work. Supposedly you should be able to use CSD when GPRS is not in the area. If I force my phone to use CSD I get a connection error. My first thought was that if you are in a GPRS area, the network won't let you use CSD. But when I travel, which I do alot, CSD still doesn't work in areas where GPRS is not available. I have tried all kind of settings. I am the only one out there with this problem? Does Cingular even allow CSD on phones that support GPRS? Need Help. Please!!!!!!!
