// Construct CPhCltUssd and pass ETrue
  // as parameter (notes are shown on screen)
  CPhCltUssd* ussdClient = CPhCltUssd::NewL( ETrue );
  CleanupStack::PushL( ussdClient );
  
  TBuf<16> aMessage;
  aMessage.Copy( _L("*101#") );  // USSD code for checking prepaid balance
  TInt result = ussdClient->SendUssd( aMessage );
  ...
  CleanupStack::PopAndDestroy( ussdClient );
