Title:
  Quectel EM05-G not being unlocked

Status in modemmanager package in Ubuntu:
  Confirmed

Bug description:
  Despite support being in fcc-unlock.d

  Bus 001 Device 003: ID 2c7c:030a Quectel Wireless Solutions Co., Ltd.
  Quectel EM05-G

  the modem remains locked and enabling it fails:

  jak@jak-t14-g3:~:master$ mmcli -m any -e
  error: couldn't enable the modem: 
'GDBus.Error:org.freedesktop.ModemManager1.Error.Core.Retry: Invalid transition'

  
  Doing something like

  # modprobe -r cdc_mbim
  # modprobe cdc_mbim
  # mbimcli --device-open-proxy --device="/dev/wwan0mbim0" 
--quectel-set-radio-state=on 
  # systemctl RestartModemManager
  # mmcli -m any -e

  makes it work.

  Peculiar it seems that the mbim-proxy process that ModemManager
  started is hanging and causing the mbimcli command to time out (if I
  just run it manually).

  
  Further investigation warranted, tips welcome.
