Try the below code and then call, sendSMS("99999999999", "message"); to send sms in desired number.

//---sends an SMS message to another device---
@SuppressWarnings("deprecation")
private void sendSMS(String phoneNumber, String message)
{        
    Log.v("phoneNumber",phoneNumber);
    Log.v("MEssage",message);
    PendingIntent pi = PendingIntent.getActivity(this, 0,
    new Intent(this, **DummyClasshere.class**), 0);                
    SmsManager sms = SmsManager.getDefault();
    sms.sendTextMessage(phoneNumber, null, message, pi, null);        
}

Please place the following permission into AndroidManifest.xml file.

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

Hope this might help.

Update From the comment: DummyClasshere.class is an activity without doing any process or the class in which u need to navigate.

You can use Object.class in place of DummyClasshere.class.
