Sending an International SMS can be a costly affair,because no free sms sites offer free International sms. I searched extensively and found out that even those sites which offered free international sms, would just show up an error message on trying to send sms to an international phone number.So the simplest way seems to be with Facebook,which provides us with free sms updates, which can be customized to update us with sms each time someone messages you on Facebook.
