Chapter 23 - Sprint® Specific AT Commands

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.
