the second port of the MC950D is by default in QCDM mode. You can send
AT$NWDMAT=1 to the first AT command channel and turn the second TTY also
into an AT command channel.

I did not find in the MC950D datasheet that it has any second port, which you said as being used for QCDM.
Where did you read about it ?

Network statistics are a different story - you're not querying the modem for those; you're querying the ppp interface. The Linux kernel keeps track of the network flowing over that interface. If you run 'ifconfig', you'll likely see ppp0 as a network interface, complete with statistics.
If the statistics can be queried from the ppp interface, it gets me closer to the idea that AT commands are not used while in ppp connection, but I now see that this device (MC950D ) can send/recieved SMS message (which I think is only done using AT command). I see that in the Mobilink application (which is used with the MC950D in windows), and I also tried it and it works.
