Phone number validator with RegexValidator?

Question

Django

I'm trying to validate an input for a phone number using RegexValidator.
I wrote the following in the user model:

phone_regex = RegexValidator(
    regex=r'^\+?1?\d{9,15}$', 
    message="Phone number must be entered in the format: '[phone]'. Up to 15 digits allowed."
)
    phone = models.CharField(validators=[phone_regex], max_length=17, blank=True)

when you enter a clumsy number into the input, the data is not saved, excellent, but
I expected that when you enter letters into the input, what was indicated in the message will fly out.
What can be connected with this, maybe this variable should be displayed somewhere?
