Free API to send Bulk SMS outside India in ASP.Net

I tried sending SMS from Asp.Net by following this article:

http://www.aspsnippets.com/Articles/How-to-send-free-SMS-from-ASPNet-application-to-Mobile.aspx

Is there any websites to sent SMS outside from India as the links provided are from India.

I can't register as I do not have India mobile number.

Thank you.
