Sending an SMS message:

ArrayList sentPendingIntents  = new ArrayList();
ArrayList deliveredPendingIntents  = new ArrayList();
PendingIntent sentPI = PendingIntent.getBroadcast(getApplicationContext(), 0, new Intent(getApplicationContext(), SmsSentReceiver.class), 0);
PendingIntent deliveredPI = PendingIntent.getBroadcast(getApplicationContext(), 0, new Intent(getApplicationContext(), SmsDeliveredReceiver.class), 0);
try {
	SmsManager sms = SmsManager.getDefault();
	ArrayList parts = sms.divideMessage(message);
	for (int i = 0; i < parts.size(); i++) {
		sentPendingIntents.add(i, sentPI);
		deliveredPendingIntents.add(i, deliveredPI);
	}
	sms.sendMultipartTextMessage(phoneNumber,null,parts,sentPendingIntents,deliveredPendingIntents);
} catch (Exception e){
	e.printStackTrace();
	Toast.makeText(getBaseContext(), "SMS sending failed...", Toast.LENGTH_SHORT).show();
}

Supports SMS delivery:

public void onReceive(Context context, Intent arg1) {
	switch (getResultCode()) {
		case Activity.RESULT_OK:
			if (ZmienneGlobalne.getInstance().global_var[3] == "1") {
				Toast.makeText(context, "SMS delivered", Toast.LENGTH_SHORT).show();
			}
			break;
		case Activity.RESULT_CANCELED:
			if (ZmienneGlobalne.getInstance().global_var[3] == "1") {
				Toast.makeText(context, "SMS not delivered", Toast.LENGTH_SHORT).show();
			}
			break;
	}
