SMS is not for free. This will not do. There are ways but you will have to pay the service. Are you still intereseted?

That's not true. You can send sms for free using SMTP (as long as you can find your opearator's sms gateway). http://en.wikipedia.org/wiki/List_of_SMS_gateways

Yes, I know that, but this is not possible in my Country (Slovenia).
