Check the Notifications Settings in the Patient Info under Marketing – is it set to System Default or is set to SMS?
If it is set to SMS, was the appointment created before Notifications were in use?
Is the Mobile number accurate and in the correct (Mobile) field? If the Patient has a Preferred contact, is their mobile number set up correctly?
What is the Sys. Default? Check in Config>Patient>Notifications – if SMS has no check against it, then Sys. Default checked in the patient will not send notifications.
In the Patient Info, firstly uncheck the Patient Sys Default, and check SMS.
If you want all Patients to default to send SMS, check the SMS box in Config.
It won’t work for existing, future dated appointments, only for appointments added after the setting is changed.
Also, check the appointment reason in Config>Scheduler – is the “Don’t send Notifications” box checked for the appointment reason that isn’t working?
There is also a similar setting in Config>Scheduler Specialist.
