It is possible to send a Terminal Response after the +STIN indication (step 2, of Messages exchanged during a SIM
Toolkit operation), or after the +STGI command (step 3).
Note: For the SETUP MENU Proactive Command, it is only possible to send a Terminal Response after the +STIN:
0 indication, not after a +STGI=0 request. All of the Terminal Responses are not possible with all of the
Proactive Commands. Compatibility between available Terminal Responses and Proactive Commands is
given in Appendix D, Table 2. If a Terminal Response is attempted during a incompatible Proactive Command
session, a +CME ERROR: 3 will be returned.
Possible error codes
+CME ERROR: 3 Operation not allowed. This error is returned when a wrong parameter is detected.
+CME ERROR: 4 Operation not supported. This error is returned when the user gives a response with
SIM Toolkit functionality not activated. Or if the SIM Toolkit indication (+STIN) has not
been received.
