No, there's a limit to 1 phone number.
When setting up your Wyze Home Monitoring system and adding your Contact Information, you only have the option to add 1 phone number. This means that in the event of an alert, that is the phone number that will be contacted by Noonlight to verify your safety.
There is not currently a way to add multiple or backup phone numbers for the Noonlight agent to attempt. But we are aware of the request and it's on our ask list.
