Answer 1

Cognito said:

Enter the user's phone number, including country code. The phone number is not a required attribute based on your selections and user pool configuration.

You are missing the country code in your phone number you have to follow the E.164 format. For example, if this is a Sri Lanka phone number, it should be written as +9480570497, where 94 is the country calling code for Sri Lanka.

Answer 2

Cognito seems to be doing some more validation besides the regex from the screenshot. For example numbers starting with +80,+21,+259 and more. Looks like it does not allow any country codes that's are currently unassigned from this list https://en.wikipedia.org/wiki/List_of_country_calling_codes
