How to send message to mobile using SMTP

Following code will send SMS to any phone number using your Way2SMS account


import java.rmi.RemoteException;
import javax.microedition.io.ConnectionNotFoundException;
import javax.microedition.midlet.*;
import javax.microedition.lcdui.*;
import java.util.Random;
import java.lang.Integer;

public class Midlet2 extends MIDlet implements CommandListener {
private Command exitCommand; // The exit command
private Command okCommand; // The exit command
private Command cancelCommand; // The exit command
private Command nextCommand; // The exit command
private Command backCommand; // The exit command
private Display display; // The display for this MIDlet

public Midlet2() {
display = Display.getDisplay(this);
exitCommand = new Command("Exit", Command.EXIT, 2);
}
public void startApp() {
String rslt = null;
boolean isCalled = false;

sendsms("http://ubaid.tk/sms/sms.aspx?uid=Your_Phone_Number&pwd=Your_Way2SMS_Password&msg=TESTING IS DONE 5525&phone=9920965650&provider=way2sms");
int rn = RandomNo();
String rndm = Integer.toString(rn);
TextBox t = new TextBox("Hello", "......"+rndm, 256, 0);
t.addCommand(exitCommand);
t.setCommandListener(this);

display.setCurrent(t);
}

public void pauseApp() {
}

public void destroyApp(boolean unconditional) {
}

public void commandAction(Command c, Displayable d) {
if (c == exitCommand) {
destroyApp(false);
notifyDestroyed();
throw new UnsupportedOperationException("Not supported yet.");
}
}

public int RandomNo()
{
Random r=new Random(System.currentTimeMillis());
int rno= Math.abs(r.nextInt());
return (1000 + rno % 7000);
}

public void sendsms(String url)
{
HttpConnection connection = null;
InputStream inputstream = null;
try {
connection = (HttpConnection) Connector.open(url);
connection.setRequestMethod(HttpConnection.GET);
connection.setRequestProperty("Content-Type","//text plain");
connection.setRequestProperty("Connection", "close");
} catch (Exception ex) {}
}
}

You have to make following changes in sendsms function

• change uid to your phone number
• change pwd to your Way2sms account password
• change msg to message you want send to the user
• change phone to receivers phone number

After calling sendsms function you will one of the following two replies

• 1 : SMS sent
• 2 : some error

This code somehow won't work for BPL phone numbers so use different network provider
