SmsManager smsManager = SmsManager.getDefault();
smsManager.sendTextMessage("", null, "< message body>", null, null);

SmsManager require, SMS_SEND permission in your android mainfeast.

<uses-permission android:name=”android.permission.SEND_SMS” />

2. Sending SMS by invoking Built-in SMS application

Intent sendIntent = new Intent(Intent.ACTION_VIEW);

	sendIntent.putExtra("sms_body", “"); 
	sendIntent.setType("vnd.android-dir/mms-sms");
	startActivity(sendIntent);
