Student phone numbers are not automatically set to receive voice and text messages. In order for students to receive school communications such as weather/emergency, general school information, and more you'll need to set what communication type each student should receive and how.
To edit student messaging options so they can receive voice and text messages go to View Student Data in jmc Office and click the "General" tab.
Step One: Select the student you'd like to receive messages by entering their name in the "Find" drop-down list.
Step Two: Right-click the cell phone icon next to the “Student Cell Phone” field to view the different messages students can receive.
Step Three: Place a checkmark in the "SMS (Text Message)" checkbox if this student's phone number can receive text messages.
Step Four: Place a checkmark in the "Emergency / Weather Related", "Student Related", and "General School Information" checkboxes for each type of message this student's phone number would like to receive.
Step Five: Click the "Save" button to have the specified student begin receiving phone calls and text messages!
