how to free sms

I need your suggestion. I have made an executable program under windows that will show the status of my server if online or offline.

What I would like now to achieve to incorporate a free sms in that program to send me an sms about the status of my server. Any ideas?

I think there is a way to do it via email, search the forums. Also, I have requested the thread moved since this isn't a vb only question.
