Note: only admins can access this screen and turn it on/off.
As a reminder, here's how the feature works:
- a text message will be sent to client profiles with a valid north american number
- the number used to satisfy the above criteria is the one in the "cell phone" field
- a reminder will be sent on the previous evening or late afternoon for appointments the next day in the morning
- a reminder will be sent in the morning for appointments in the afternoon / evening on the same day
- the text of the reminder is as follows: "Appointment reminder: BUSINESSNAME DATEANDTIME local time. See email for details. No reply."
