What's the name of Korean chat app?

There are the following Korean chat applications:

1、Kakaotalk

This software is similar to our domestic WeChat, and it is the most commonly used chat software for Koreans. KKT has added the functions of finding friends' phone numbers, video and voice calls, as well as transferring money and QR code payment. China's mobile phone number can also be used to register an account.

2、Hellotalk

HelloTalk has a bilingual translation function between China and South Korea, and many foreign students who have just gone to Korea will look for partners on it. This software is still used by Koreans who are learning Chinese, so it is also a good way to improve Korean.

3. Band

This is a Korean community software, similar to our Douban and Post Bar. Users can choose to enter a specific section according to their hobbies, where they can find many hobbies and discuss them together.

Ka Kao, tell me about the introduction.

Ka Kao is a free chat software from South Korea, and China Tencent is its second largest shareholder. Similar to QQ WeChat chat software, it can be used for communication applications between smartphones such as iPhone, Android, WP and BlackBerry.

This application manages friends through the actual phone number, and with the help of push notification service, it can quickly send and receive information, pictures, videos and voice intercom with friends, relatives and colleagues. Similar to QQ in China, even if your friends are not online, they can receive your Ka Kao talk message, just like texting.
