Again, please elaborate. Much of Sim Toolkit depends on access to files that
can only be accessed with PIN entered. So leaving STK atom in a fully
functional state is not the answer either.
Why would stk be unusuable. Is it that we cannot recover the Main Menu
state after re-creating it?
Yes. There is no way to retrieve the main menu again. It also may at that time SAT
stay at the main menu.
