Question

Here I am using the Blackberry simulator 8520. I want to receive an sms in my Blackberry application without notifying the inbox (silently).

UiApplication.getUiApplication().invokeLater(new Runnable()
{
    public void run() 
    {
        // TODO Auto-generated method stub      
        try
        {
            DatagramConnection dc =(DatagramConnection)Connector.open("sms://");

            for(;;)
            { 
                Datagram d = dc.newDatagram(dc.getMaximumLength());
                dc.receive(d);
                byte[] bytes = d.getData();
                String address=new String(bytes);
                String msg = new String(bytes);
                String message=msg.toString();
                add(new RichTextField(message));
                add(new RichTextField(address));
         }
         catch(Exception e)
         {
             e.printStackTrace();   
         }
    }
});

The SMS message will have to be sent to a port other than port 0 (the default)
Connector.open("sms://:1500"); and your program will have to be listening on the port when the message arrives. If you send an SMS message from a BlackBerry to a port other than 0 it is actually sent to 0 or the port specified so if there is no server listening to the port the message is delivered to the inbox.
