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.
