             long currentDataConnectionMultiSimId =  Settings.System.getLong(mContext.getContentResolver(), Settings.System.GPRS_CONNECTION_SIM_SETTING, Settings.System.DEFAULT_SIM_NOT_SET);

             currentDataConnectionSimId = SIMInfo.getSlotById(mContext, currentDataConnectionMultiSimId);

         }else{

             currentDataConnectionSimId = Settings.System.getInt(mContext.getContentResolver(), GPRS_CONNECTION_SETTING, GPRS_CONNECTION_SETTING_DEFAULT) - 1;

         }



   if(currentDataConnectionSimId < 0){

                 return Phone.APN_REQUEST_FAILED;
