You can receive STAFF text (SMS) notifications if your phone carrier supports email to text gateways. We have CLIENT text reminders you can enable for all north american phone numbers (no need for anything but the phone number itself) but STAFF text notifications can only be achieved if your phone carrier supports the above.
Check with your carrier to find out if they support it and what email address you must use. If supported, you will then be able to add your email to text email address to our notification system and receive text notifications for new/modified appointments.
In your account, add a new user under "my account" > "all users" with the appropriate email to text email address and assigned to the relevant schedule(s) you wish to be notified about.
