@tom This is a test SIM and the manufacture does support Sierra wireless. It uses the GSMA TS48 SIM profile which is a universal test profile that works with everything I have used it with as well. When we inject a signal from a base station emulator the EM9291 does not respond and this SIM works with other devices when connecting to the emulator.

Ok I wasn't sure because the EM9291 user guide states both QC and Sierra wireless should show up but yes that is not used as a add-on board.

Any idea why the wds service is giving the error?

@Gus-Meyer It looks to be some kind of configuration issue rather than a hardware issue. If I turn on the board while pressing the S2 switch, the USB connection is recognized. But I'm assuming this puts it in some particular mode where the device isn't used normally, because I do not receive an IP on the ethernet device under this circumstance.
