  • @DeepShah Inside Block/PhoneNumber.php file comment or remove this line, "preferredCountries" => [$this->helper->preferedCountry()]. and then it should work fine. Oct 29, 2021 at 7:17

You can use the below extension, it automatically adds validation based on the selected country with the country flags and automatically sets the user country by default based on their Geo IP location. It is also supported with the latest Magento 2.4.5 version as well.
