sms workflow integration

sms workflow integration

I'd like to know that once we decide to set up SMS with one of the providers on zoho; can we set up a rule/workflow whereby once someone registers ona course with us, they automatically get a welcome notification from us?

EG

We have people signing up for training courses and once they register, I want them to receive an SMS message from us welcoming them to the program.

My question;

Can this be done
How can it be done?

Thanks
