If they are including smtp, I believe that falls under Email Notification. But my requirement is if I give a phone number, message should be sent to that just like Way2Sms. Could u please correct me if i miss anything here.
You can use Fast2SMS API to send SMS if you are allowed to go for any other method than corr rule. It's quite easy to implement. You can use twilio component too. But it supports only US numbers I guess. Go for Fast2SMS. It will work for sure.
