One of the defining features of KakaoTalk is its Plus Friend feature, which allows KakaoTalk messenger users to receive special content and updates from their favorite artists by adding them as a Plus Friend. This feature also enables users to participate in events for their Plus Friends. The KakaoTalk service also allows its users to export their messages and save them for future reference if the user so desires.
The South Korean application also supports various add-ons including KakaoStory, which provides a profile page of sorts where users can post photos, messages, and receive birthday greetings; and various games, along with additional add-ons to increase functionality.
Like many other VoIP services, KakaoTalk works over both Wi-Fi networks and 3G mobile networks, allowing users to stay in touch with friends and family whether they’re a mile or an ocean away.
