As most people are rather busy, the tendency for them to overlook an appointment is quite real. Therefore, it is good practice to send them a reminder via email or WhatsApp 2 or 3 days before the meeting. It not only saves you time in commuting back and forth if it is postponed, it also shows your professionalism and that you value your time.
Subject: Appointment confirmation on [DATE]
Hope you're having a great week.

I appreciate the time you have set aside for me, and I am very much looking forward to our meeting.
Should you find it necessary to reach me prior to our appointment, my number is [PHONE] or you can reply to this email.
