You can set appointment reminders in Maintenance, Branch & System and then System Parameters.

1. Check the 'Send SMS appointment reminders' box.
2. Enter the number of days before the appointment you would like the reminder to be sent.
3. Type your reminder message in the box. This will already have a generic message entered.
4. You can add merge fields by clicking 'Select Merge Field' and selecting from the options.
5. If you are sending out automatic message reminders, we recommend that you set a time in order to stop text messages going out at unsociable hours.
