How can I use the SIxfab Cellular modem with OpenWRT?

I tried recently tried using the sixfab modem with the telit SIM chip with OpenWRT but was not able to get it working with the QMI cellular connection. I was able to see that I am able to get a connection with the device and send commands to it but for whatever reason I cannot read any data coming through. Does anyone have any ideas what could be going on? Maybe I need to install a dependency that I’m missing?
