Hello – have you experienced the same problem?
Modem was being able to coonect to UGW but now the RadioPowerOFF flag is on.
How to turn the EM9293 radio power on???

Other user can make it work
I just have tried on my module, no problem is found.
After typing the mbimcli command in ubuntu 18, AT+CFUN? returns online:
owner@ubuntu:~$ sudo mbimcli -d /dev/cdc-wdm0 -v -p --set-radio-state=on
