Taking a quick look at the spec here:
http://www.quectel.com/UploadFile/Product/Quectel_EP06_LTE-A_Specification_V1.2_.pdf

I see it uses UMI as the other Quectel modules, and usb3, so i would think it will work fine, but not 100%. I have not seen anyone else using it.

Worst case it would require just a few changes to config files in OpenWrt.
