When you are in Korea, every step needs confirmation and this app is one of the Virtual signature platforms. But it is the worst app ever! It signs me out any time it wants, doesn't let me sign in again, and always says the SIM information is wrong, and guess what! It happens all of a sudden when I need it the most! So inconvenient, so bothersome.

I think the designers have some kind of mental handicap? the app is exclusively in korean with no language setting AND disables screenshots so I can't even translate it. someone is VERY senile in the design department.

Pathetic app experience. No English support. Doesn't allow screenshot so can't translate as well. App will just close if sim is not inserted in slot 1. If sim is in slot 1, but default calls and msg is set to sim2, app will still not work. Even after this, need to switch off and switch on the phone and enable mobile data initially for the app to login. After long trouble it might work, but even after that, trouble doesn't end due to no English support.
