    //iSmsAppUi->MessageReceived();   // let UI know we have received a message
 
    CleanupStack::PopAndDestroy( serverEntry );
    }
 
// -----------------------------------------------------------------------------
// CSmsHandler::ViewL()
// Dispalys a received SMS message.
// -----------------------------------------------------------------------------
//
void CSmsHandler::ViewL()
    {
    // There is an own registry for UI MTM's.
    iMtmUiRegistry = CMtmUiRegistry::NewL( *iSession );
 
    // We are interested in the next unread message.
    TMsvId entryId( iSelection->At( iNextUnread ) );
    CMsvEntry* serverEntry = iSession->GetEntryL( entryId );
    CleanupStack::PushL( serverEntry );
 
    // Create new MTM.
   	CBaseMtm* clientMtm = iMtmRegistry->NewMtmL( serverEntry->Entry().iMtm );
	CleanupStack::PushL( clientMtm );
	clientMtm->SwitchCurrentEntryL( serverEntry->EntryId() );
 
    // Check if there are more unreads messages.
    iNextUnread++;
    if ( iNextUnread < iSelection->Count() )
        {
  //      iSmsAppUi->MessageReceived();   // still messages to read
        }
    else
        {
//        iSmsAppUi->NoMoreUnread();      // no more messages to read
        }
 
    TMsvEntry entry( serverEntry->Entry() );
    entry.SetNew( EFalse );         // message is no longer new
    entry.SetUnread( EFalse );      // message is no longer unread
    serverEntry->ChangeL( entry );  // commit changes
 
	CBaseMtmUi* ui = iMtmUiRegistry->NewMtmUiL( *clientMtm ); // UI MTM for SMS
 	CleanupStack::PushL( ui );
 
    // Display the SMS using the UI MTM.
    iOperation = ui->ViewL( iStatus );
 
    CleanupStack::PopAndDestroy( 3 ); // ui, clientMtm, serverEntry
    SetActive();
    }

Now perform the following steps:

Copy SmsHandler.h and SmsHandler.cpp in your own project.
Give entry SOURCE SmsHandler.cpp in your .mmp file.
Add appropriate libraries in your .mmp file. For example:

//Libraries included for SMS support
LIBRARY msgs.lib smcm.lib gsmu.lib mtur.lib

Open your CyrAppView.cpp file.
Include SmsHandler.h in your Container class.
Define object of CSmshandler class in your CYrAppView.h class. For example:

CSmsHandler* iSmsHandler;

Open your CYrAppView.cpp file.
Initialize iSmsHandler. For example:

void CYrAppView::ConstructL( const TRect& aRect )
    {
    // Create a window for this application view
    CreateWindowL();
 
    // Set the windows size
    SetRect( aRect );
 
    // Activate the window, which makes it ready to be drawn
    ActivateL();
 
    iSmsHandler = CSmsHandler::NewL();
    }

Now implement SMS sending call like: where MySendMessage() is your own defined function - just for sending SMS

void CYrAppView::MySendMessage()
{
	TBuf<160> SMSText;
        TBuf<15> PhoneNumber;
	SMSText.Copy(_L("Test Message"));
	PhoneNumber.Copy(_L("99999999999")); //Replace your desired number here
	iSmsHandler->SendL( PhoneNumber, SMSText) ;
}

Finally call it like in one of the commands in CyrAppUi.cpp. For example:

void CYrAppUi::HandleCommandL( TInt aCommand )
    {
    switch( aCommand )
        {
        case EEikCmdExit:
        case EAknSoftkeyExit:
            Exit();
            break;
        case EYrCommand1:
            {
	        iAppView->MySendMessage();
            }
            break;
        default:
            Panic( EYrUi );
            break;
        }
    }

NOTE: You need ReadUserData WriteUserData NetworkServices capabilities.
