Access Overload Class +WAOC
Description:
specifically to modify the AOC value, it will retain this value and will not be automatically updated via the WIMI or
WMDN commands. Otherwise, if the AOC has not been modified via the WAOC command, it will be automatically
updated to be the last digit of the MDN (WMDN) or IMSI (WIMI) when the commit (WCMT=1) command is issued.

This command is used to set the Access Overload Class. If the +WAOC command is used
Command syntax: AT+WAOC=<number>
<number>
This command is used to commit or to undo/revert any changes done during the service
programming session. Changes performed during this session will not take place until a commit
command has been sent (AT+WCMT=1). Commission of these changes will force a software
reset of the modem. Sending this command indicates this service provisioning session is
complete. In order to perform any subsequent provisioning, the service programming code must
be entered using the +WSPC command.
Command syntax: AT+WCMT=<val>
<val>
This command is used to set the IMSI. S valid IMSI is 15 digits in length: MCC (3), MNC (2),
MIN2 (3), MIN1 (7). For support of Wireless Number Portability, changes to the IMSI will NOT
update the MDN. If the MDN is modified via the WMDN command, the IMSI_M portion of the IMSI
will be automatically updated to the least significant 10 digits of the MDN, but the update will not
be visible or applied until the commit command is issued via the WCMT command. Changes to
the IMSI will automatically update Access Overload Class values unless specifically modified
using +WAOC.
