Regarding free SMS sending service to test java application

[Vinod Vijay]

Hi,

I'm developing a web application using Java. I would like to integrate SMS service in my application. For this, I would like to test SMS notification on mobile numbers globally. May I know if there is any free service or open source frameworks available for SMS alerts testing purpose.

Thank you
