You have to use a BroadcastReceiver to schedule events with AlarmManager. Extend BroadcastReceiver and override the onReceive() method, then your device will wakeup for the time required to complete that method. This will let you send your SMS or start a service.

class MyReceiver extends BroadcastReceiver
{
    @Override
    public void onReceive(final Context context, final Intent intent) {
        //YOUR CODE HERE
    }
}

Notice that the Wakelock which keeps the device active will only last for the whole onReceive method, so if you start a service or an activity they may not execute all their code before the device goes back to sleep.

In this case the pendingIntent has to be created using "getBroadcast" instead of "getService".
