Most CDMA 1x/EVDO devices don't do PINs the same way that GSM/WCDMA
devices do, so I don't think PIN codes are the problem here.  It's a
limitation with the way that CDMA devices are currently used, because
they usually have on AT-capable port with a very limited command set,
and one or more additional ports that talk the Qualcomm Diagnostic
Monitor protocol (which some Qualcomm-based WCDMA devices also use).
The problem is that the AT command port doesn't have sufficient
capability to report the CDMA 1x registration status separately from the
EVDO registration status.
