send SMS from MIDlet

[barak_obama]

How can I sen SMS with java, from MIDlet? What port I have to use, and where is number of message center?
Does this work?

 String addr = "sms://+123456789:50000";
MessageConnection conn = (MessageConnection)Connector.open(addr);
TextMessage msg = (TextMessage)conn.newMessage(MessageConnection.TEXT_MESSAGE);
msg.setPayloadText("Hello World!");
conn.send(msg);
