When we "teach" students in class in order to help them learn, we don't just help them understand the content of the lesson. We also provide tips, motivate them to do activities that will help move them along in the course, get them to participate in discussions and manage their learning/the course. It was the same with the SMSes. We believe, the will get enough content from the print module provided and from the face-to-face interactions with their tutors. So yes, m-learning was used to help "teach" as well as "manage" the student.
