Wireless Joint

I got the The Wireless Haven USB3.0 to NGFF M.2 Key B 4G 5G Modem Adapter Enclosure with SIM Card Slot setup connected to a ROOter RPI4 via USB 3.0. It see's the modem fine but no matter how I position the 6-pin nano-sim (in a STD adapter) it cannot read the SIM. I've tried pushing it in deeper, shallower, etc... with no luck.
What's the trick to get the nano-sim positioned correctly in the SIM slot? I've tried every position for the sim

The modem reports no SIM with AT commands, this sim works fine in my WG1608 with the same SIM standard size adapter.

Just to double check, are you using a SIM adapter, like the Noosy? You have to be really vigilant getting a nano sim into the adapter and keeping it properly aligned as you insert it into the USB box.

Also, are you using the latest Rooter version for the RPI 4? I think they just released a new one the other day.
