Mobile Directory Number +WMDN
Description:
This command is used to enter a new mobile directory number. Valid numbers are between 10 and 15 digits
in length. For support of Wireless Number Portability, changes to the MDN will
ALWAYS
update the IMSI_M
portion (least significant 10 digits) of the IMSI. Changes to the MDN will also automatically update the
Access Overload Class values unless specifically modified using the +WAOC command. The new IMSI_M
and Access Overload Class values will not be visible in the WIMI and WAOC commands until after the
changes are committed with the WCMT command.
The security PIN (WPIN) is automatically updated using the following logic whenever the +WMDN command
is used to change the mobile directory number (MDN).
If (Security PIN = Last 4 digits of MDNold) Then
Set Security PIN = Last 4 digits of MDNnew
Else
Don't Change Security PIN
EndIf
Example 1:
Current PIN = 1234
Current MDN = 5551234 (last 4 digits are the same as PIN digits)
If MDN is set to 5556789, then PIN changes to 6789.
Example 2:
Current PIN = 3456
Current MDN = 5551234 (last 4 digits and the PIN digits are different)
If MDN is set to 5556789, then PIN remains 3456.
