Welcome to the User Community Forum @afernando.
There is currently no SMS notification or Phone Call\VOIP capability for Smart AI Event Notifications in the Wyze App.
There is currently a Wishlist item requesting this:
The Alexa option mentioned above is one alternative. Another is a third party app called MacroDroid. It can be programmed to send an SMS to your phone when a Push Notification is received from Wyze indicating a Smart AI Person Detection on a specified cam.
I believe Tasker is also an app that can do this although I do not use it.
