You can do it by extending BroadcastReceiver.

public class MyBootReceiver extends BroadcastReceiver
{
@Override
public void onReceive(Context context, Intent intent)
{
// Your SMS logic
}
}

Then you need to add android.permission.RECEIVE_BOOT_COMPLETED permission in Androidmanifest.xml as well as your BroadcastReceiver
