MC7354 doesn't support for Sprint/Verizon HDR mode

IoT Modules MC/EM Series

When I try Sprint/Verizon carrier sim card on MC7354, it doesn’t work properly once it enters HDR mode and lots of AT Commands are invalid or weird.

AT+CREG=1

Note: when the card gets plugged in, it is in LTE mode and everything works fine; but after for a while when it become to HDR mode, I gets above AT command responses and does not work at all.

I know why I get unresponsive AT commands because some of these are not CDMA/HDR commands. My question is that does MC7354 card has any CDMA/HDR supported AT commands allowed me to get above information from the card? If no, how should I get them?

Thanks
