Not accepting Mexican phone numbers: 5215563189961

[NoirKomBatman]

My code:

	sms = strings.TrimSpace("5215563189961")
	if sms == "" {
		return "", errors.WithStack(ErrEmptyPhoneNumber)
	}
	number, err := libphonenumber.Parse(sms, DefaultSMSRegion)
	if err != nil {
		return out, errors.WithStack(err)
	}
	if !libphonenumber.IsValidNumber(number) {
		return out, errors.WithStack(ErrInvalidPhoneNumber)
	}

Getting invalid phone number
