Enter Automatic PIN Entry Option
The following key sequence is used to enable or disable the automatic PIN entry:
Label: ENABLE AUTO PIN
Data: <auto_PIN>
*
<PIN>
The auto PIN value is set to 0 to disable automatic PIN entry; set to 1 to enable
automatic PIN entry. If the auto PIN value is neither 0 nor 1, it is considered
invalid. The factory default value is 0 (disabled). The factory default setting for the
PIN is "1234".
Enter PIN For Automatic PIN Entry
The following key sequence is used to change the SIM PIN for automatic PIN entry:
Label: CHANGE AUTO PIN
Data: <old_PIN>
*
<new_PIN>
The factory default setting for the PIN is "1234". The new SIM PIN is supplied by
the service provider with a new SIM.
NOTE: This command does not change the PIN encoded on the SIM by the service
provider. It only changes the PIN supplied for automatic PIN entry by the FWT to match
that encoded on the SIM. See the SIM Card Installation and Setup section of this manual
for instructions to change the PINs encoded on the SIM.
