Question: In a Java Card (U)SIM environment, as per 3GPP specifications, what happens to an `ISOException` with reason code (0x6FXX) thrown by an Applet triggered by `EVENT_FORMATTED_SMS_PP_ENV`?
Option 1: It is silently ignored by the (U)SAT Framework without notification.
Option 2: It is sent to the terminal, while other exceptions are not propagated.
Option 3: All exceptions, including this specific ISOException, are always propagated to the terminal.
Option 4: The Applet is automatically terminated upon throwing such an exception.
Explanation: According to the specified behavior for exception handling in the (U)SIM API for Java Card, when an Applet triggered by `EVENT_FORMATTED_SMS_PP_ENV` throws an `ISOException` with reason code (0x6FXX), it is specifically designed to be sent to the terminal. This differentiated handling highlights that not all exceptions are treated equally in terms of propagation to the terminal, emphasizing the importance of exception type and context in determining the system's response.
