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.

Tried authenticating a mobile service website through PASS but it says I have no authentication info on PASS which is weird. No further information on how to solve the issue was provided.

No English option, and couldn't take a screen shot to translate. Doesn't explain, even in Korean what I have to input properly next to DOB, which didn't authenticate. No idea what error 17 means. Despite my difficulties I managed to figure it out in the end.
