Introduction
If you’re spending time in Korea, you’ll quickly notice one app that everyone seems to have on their phone: KakaoTalk. From friends making weekend plans to businesses sending out special offers, KakaoTalk (or just “KaTalk”) is a huge part of daily life here. But what makes it so popular, and should you think about downloading it for your trip?
What is KakaoTalk?
KakaoTalk (카카오톡) is South Korea’s most widely used messaging app – in fact, over 90% of Koreans use it every single day. It works similarly to apps like WhatsApp, LINE, or Telegram, but with a much deeper integration into Korean life.
It’s completely free to download and works over Wi-Fi or mobile data. More than just messaging, it’s a platform where you can chat, call, shop, pay for things, and even get your bank or delivery updates – all in one place.

How to Download & Set Up KakaoTalk

Pro tip: If you’re getting a Korean SIM/eSIM during your trip, you can register with that number so locals can find you more easily.

But if you plan to meet locals, join events, or book smaller guesthouses, having KakaoTalk will make communication much easier. Since it’s free and quick to set up, it’s worth having just in case.
