Hi,
Webcon does not provide SMS functionality, although you could leverage REST/SOAP actions.
There are many SMS API providers, maybe even your company have a contract with some telecomunication company which could provide such API.
Hi,
the SMS API may be the easiest one to use, but there's also a nice post for an own SMS gateway approach on this blog:

The blog itself is no longer actively maintained.
Best regards,
