Can I use the application used in Korea even if I plug in the local USIM?

When I go abroad, can I use an application that I use in Korea with a local USIM?

I didn't know I could contact you through Kakao Talk.

Anyway, if you plug in the USIM, it'll allow you to use the Internet, and you can use it anywhere in the world
You can do anything including Kakao Talk
