A Design Studio SMS doesn't send anything on its own. After you [create](/integrations/api/design-studio/tag/sms/createSms/) an SMS, you [link](/integrations/api/design-studio/tag/sms-link-and-publish/linkSms/) it to a single workflow, like an SMS action in an automation or a transactional message. Then you [publish](/integrations/api/design-studio/tag/sms-link-and-publish/publishSms/) to push your updates from Design Studio to that workflow.
