http://androidforums.com – Ok, i have looked everywhere and tried doing my research to fix this but i have yet to find a solution... just an FYI haha But for some reason my phone has been acting up very strongly with its service/reception/signal, or i dont really know where to pinpoint the problem. Im able to pick up roaming signal, but i still cannot send/receive messages through roaming and no phone call and no internet, and the ONLY phone call i can make is the *228, BUT i have tried updating the roaming list to fix the problem and just tells me it was unsuccessful. Then i tried changing the settings under Mobile Ne (General)
