BlackBerry上接受SMS有几种方法:

使用 DatagramConnection （包：javax.microedition.io）

DatagramConnection _dc =
     (DatagramConnection)Connector.open("sms://");
            for(;;)
        {
               Datagram d = _dc.newDatagram(_dc.getMaximumLength());
               _dc.receive(d);
               byte[] bytes = d.getData();
               String address = d.getAddress();
               String msg = new String(bytes);
               System.out.println( "Received SMS text from " + address + " : " + msg);
         }

a) 使用MessageConnection（包javax.wireless.messaging）

MessageConnection _mc = (MessageConnection)Connector.open("sms://:0");

for(;;)
{
Message m = _mc.receive();
String address = m.getAddress();
String msg = null;
     if ( m instanceof TextMessage )
     {
          TextMessage tm = (TextMessage)m;
          msg = tm.getPayloadText();
     }
     else if (m instance of BinaryMessage) {

          StringBuffer buf = new StringBuffer();
          byte[] data = ((BinaryMessage) m).getPayloadData();
          // convert Binary Data to Text
          msg = new String(data, "UTF-8");
     }
     else
          System.out.println("Invalid Message Format");
          System.out.println("Received SMS text from " + address + " : " + msg);
}

b)使用 MessageConnection 的另一种方法：实现接口javax.wireless.messaging.MessageListener

MessageConnection _mc = (MessageConnection)Connector.open("sms://:0");
_mc.setMessageListener(this);

…

public void notifyIncomingMessage(MessageConnection conn) {
     Message m = _mc.receive();
     String address = m.getAddress();
     String msg = null;
          if ( m instanceof TextMessage )
          {
               TextMessage tm = (TextMessage)m;
               msg = tm.getPayloadText();
          }
          else if (m instance of BinaryMessage) {
               StringBuffer buf = new StringBuffer();
               byte[] data = ((BinaryMessage) m).getPayloadData();

               // convert Binary Data to Text
               msg = new String(data, "UTF-8");
          }
          else
               System.out.println("Invalid Message Format");
               System.out.println("Received SMS text from " + address + " : " + msg);
}
