I met a girl from Korea and she invited me to communicate with her using KakaoTalk. Where can I download this application? How does it work?

This is a good way to communicate, but you should understand that it is better to use fake personal data instead of your own in case fraudsters break into your account. In addition, phone verification will be required. Therefore, you can use a virtual number to register in Kakaotalk without phone number https://sms-man.com/blog/how-to-sign-up-for-kakaotalk-without-a-phone-number-on-ios-android-and-pc/
