KakaoTalk lets you make calls and texts for free. This messaging app has been chosen by over 150 million users, and for good reason. It lets users find an alternative to a traditional phone plan by offering the full breadth of data functions major providers offer directly through a WiFi network. While many users won't find this a suitable replacement for their data plan, the increased prevalence of free WiFi makes it an increasingly feasible prospect.

The key feature set is intended to replicate the core functions of a phone, and it accomplishes this admirably. SMS, photo messaging, and group texts are all supported directly through the KakaoTalk interface. These are supported by a vast selection of stickers and emoticons. Free calling is also available with crisp voice and video calling. Since KakaoTalk relies on a WiFi connection, the quality of your internet can have a critical impact on the reception of your calls, but reliable networks can deliver texts immediately and relay calls with few hitches or hiccups.

KakaoTalk also makes use of a board system as an effective way to keep your friends and family up to date about upcoming events and a private calendar for our own use.
