Your user name/password problem sounds strange. I do not have Cellular South, so I'm somewhat clueless in regard to your network log-in. Nonetheless, it sounds like a network authentication issue. Do you have the option available in your settings to update your profile OTA? If so, run it, and see if it updates your user name and password. Also, not sure if it will help, but you could try installing your specific DCD Carrier cab. The combination of the two may help fix the network log-in issues. Regardless, please let us know what fixes the issue, so other members can learn the solution as well.

Best to all,
