Hello sabuelh@gmail.com Welcome to the Canvas Community. Thank you for posting your question.
Every user in Canvas (instructor, student, TA, Admin, etc.) can control his/her own notification preferences. There is nothing that I am aware of in Canvas that would allow you to target a message specifically to your students' cell phones via text message. Take a look at these two Guides (which are quite similar, by the way):
How do I set my Canvas notification preferences as an instructor?
https://community.canvaslms.com/docs/DOC-10624-4212710344
As you can see from the screen shots in those Guides, each student has the option to add his/her own cell phone to his/her account (it's not a requirement in Canvas). And, once a student adds his/her own cell phone number, he/she can further decide what kinds of text messages to receive. This is not per course. Rather, it is for an entire account...so if a student chooses to receive text messages for course announcements, he/she will get those notifications for all courses...not just a single course. So, using this Notifications screen, it is very possible that one student may choose to get notifications only via a school-issued e-mail address, but another student may only wish to receive notifications via text message. A third student may wish to receive a combination of the two. It's completely up to the user.
I hope this helps to answer your question. Please let Community members know if there are any additional related questions. Thanks!
