    I am having Samsung Galaxy Y-Duos Lite GT-S5302 mobile.
    When i check for account balance, it gives USSD code running and after that
    MMI complete message is shown. No info of account balance is displayed.
    I am not able to make outgoing calls or receive incoming calls.
    Please help me to solve this issue.
