To start using KakaoTalk, as usual, you have to link a phone number to your account. Once you have done this, you can begin to add all the contacts in your address book. Text messages, videos, photos - you can send whatever you want with just a touch on the screen.
In addition, KakaoTalk allows voice calls over an active Internet connection (preferably WiFi). In these calls, you can also use the famous Talking Tom Cat effect.
Another possibility to communicate by voice is the so called 'walkie talkie' mode, in which you only have to hold down the screen and talk to record a short voice message and send it to your contacts.
As is the case with other instant messaging tools, KakaoTalk lets you create chat groups, add more than a hundred different emoticons to your conversations, and customize the look of the application.
KakaoTalk is an excellent choice among the many instant messaging tools out there, and you can communicate with any other user who has it installed on their terminal. Also, it is available on both iOS and Android!
