15.7 AT^SSTGI SAT Get Information - Refresh (1)
The AT^SSTGI=1 command shall be used after receiving the URC "^SSTN: 1". This URC notifies the TE that
one or more Elementary Files on the SIM have been changed as a result of a SIM application activity, usually
caused by the network provider. The response to the AT^SSTGI=1 command indicates what type of SIM refresh
has occurred. The change requires that the Elementary Files of the SIM be synchronized with the equivalent
information (if any) stored inside the TE. Depending on the type of SIM refresh the TE may need to use the
AT+CRSM command to read out the Elementary Files and store the refreshed information.
The response parameters <pathLen>, <fileNum> and <fileList> are mandatory if <commandDetails>
equals 1 or 2. In all other cases they are optional and can be ignored.
Syntax
Parameter Description
1 Proactive command ID, see Section 15.3, Remote-SAT Command Types and
Table 15.6.
For every return value of <commandDetails> other than 4 (SIM Reset) the TE shall complete the proactive
command cycle using AT^SSTGI=1.
0 SIM Initialization and Full File Change Notification
1 File Change Notification
2 SIM Initialization and File Change Notification
3 SIM Initialization
4 Value "4" means SIM Reset, but the value itself never appears. This is because
value "4" is mapped to the URC "^SSTN: 255" which will be sent when a SIM
reset occurs. In this case, the TE does not need to respond, i.e. the SIM
Refresh commands AT^SSTGI and AT^SSTR are neither required nor allowed.
Instead, as the SIM application restarts, the Toolkit application inside the TE
should also return to initial state after receiving the URC "^SSTN: 255". For
more information on SIM reset and the URC "^SSTN: 255" refer to Section
15.5, ^SSTN SAT Notification.
