In the picture and my writing, the 4G module is the Quectel EM06-A I purchased from Seeed because of its compatibility with the X86J4105. This X86J4105 came with Windows 10 installed. As I said, all of the devices I should be seeing in Device Manager are there. There is no error reported. In the Networking section of the Control Panel, I can see the Cellular modem trying to initialize itself. Every 10 seconds or so, it will try to initialize and fails. There is no actual error reported; it just keeps trying to start.
Despite that, I can use Putty to connect to the cellular modem and interact with it using AT commands. I can see that the cellular modem is saying it doesn’t see the SIM card. It tells me it’s an EM06-A and otherwise will report various things. It seems to be the driver isn’t right. Also, Microsoft updated the installed Windows 10 to build 2004, which is relatively new and comprehensive. Windows 10 is working well otherwise.
One question I have: when you look at the picture of my SIM card plugged in, does it look correct as far as how far it goes into the socket. When I put in an SD card into the upper socket, it goes in much farther. This may be normal - I don’t know. Is it normal?
