I don't know if I do anything wrong, but I have never been able to list
previously received (i.e. prior to starting MM) SMSes using MBIM.  This
is the same with all my MBIM modems.

Using the DWM-156 A7 as an example, I can manually send:

03 00 00 00 3c 00 00 00 01 00 00 00 01 00 00 00 00 00 00 00 53 3f be eb
14 fe 44 67 9f 90 33 a2 23 e5 6c 3f 02 00 00 00 00 00 00 00 0c 00 00 00
00 00 00 00 00 00 00 00 00 00 00 00 

and receive the list of 1 stored SMS (with the origin phone number
slighly modified here):

03 00 00 80 08 01 00 00 01 00 00 00 01 00 00 00 00 00 00 00 53 3f be eb
14 fe 44 67 9f 90 33 a2 23 e5 6c 3f 02 00 00 00 00 00 00 00 d8 00 00 00
00 00 00 00 01 00 00 00 10 00 00 00 c8 00 00 00 01 00 00 00 01 00 00 00
10 00 00 00 1c 00 00 00 06 91 74 09 00 12 00 04 0a 91 74 00 00 00 00 00

I'm attaching the MM log of this modem being probed and then sent these
commands: 

 bjorn at nemi:~$  mmcli -i 0 --pin=xxxx
 successfully sent PIN code to the SIM
 bjorn at nemi:~$  mmcli -m 0 -e
 successfully enabled the modem
 bjorn at nemi:~$  mmcli -m 0  --messaging-list-sms
 
 No SMS messages were found
 bjorn at nemi:~$  mmcli -m 0  --messaging-list-sms
 
 No SMS messages were found


As you can see, there are absolutely no 'sms' commands in that log.  The
only 'sms' service CID seen is the 'configuration' indication.  But MM
never attempt to retrieve the list of stored messages.

This is particularily obvious with the QMI/MBIM modems, where the
stored messages will be listed in QMI mode but not in MBIM mode.
