> Thanks for your explanation. I could scan the modem after put the udev folder to /lib folder. For now, I would meet a 3gpp network register issue. It seems that MM would auto-connect the available network because I could create the connection at my first test. After that, I always fail in the same test. The attachment is the log in my test, could you find anything wrong in the log?<br>

<br>
I don't see anything in the log that would explain why you're not registered.<br>
Can you confirm the hardware setup is ok? i.e. you do have a proper<br>
antenna plugged in the module, right?<br>
<br>
Maybe try to run a "sudo mmcli -m0 --3gpp-scan --timeout=300" to see<br>
if the module reports available networks?<br>
