[OpenWrt-Devel] Unable to read SMS with uqmi

Hi all. Sorry if It's not right place to ask this question.
I got a gl-inet Domino board having a Quectel UC20 UMTS/HSPA+ module 
installed on. I was under the impression that it can talk with QMI but
checked website, realized It's nowhere mentioned so. On the other hand on
booting I see kernel `qmi_wwan` makes device `/dev/cdc-wdm0` and detects it
as QMI undrestanding interface:
[ 47.272115] qmi_wwan 1-1.2:1.4: cdc-wdm0: USB WDM device
[ 47.277431] qmi_wwan 1-1.2:1.4 wwan0: register 'qmi_wwan' at
usb-ehci-platform-1.2, WWAN/QMI device, 02:77:4d:a8:b1:ec
[ 47.287013] usbcore: registered new interface driver qmi_wwan
I can even send some commands with uqmi to module, like setting PIN,
networks and registering on network; but I cannot read SMS while I can read
them with AT commands from serial interface.
I updated uqmi to last commit (d682e966615fc652da6e4e26b57aa3adfebeb2fe)
and still `--list-messages` returns empty. Linux version is 4.4.14.
This is first time I play with a (presumably) QMI interface and my first
exprience with OpenWrt. I'm very grateful of any input giving me an idea
understand what is wrong and if It's something with uqmi I may be able to
participate solve the problem.
I got a Quectel_UC20_Mini_PCIe_Hardware_Design_V1.3 document from  and
It's mentioned there, this modules is based on Qualcomm MDM6200 platform.
I'm not sure what does platform mean here, but If It's a Gobi modem It's
known to provide QMI.
