      What were you trying to do that didn't work?

      Trying to enable the modem in the ThinkPad T14 Gen 6 is very complicated, it doesn't work out of the box as there is an FCC unlocker, we should somehow map the device id and modem id and deliver fcc unlocker directly to the etc/modemmanager directory. Or we need to write documentation about it.

       

      ln -sf /usr/share/ModemManager/fcc-unlock.available.d/2c7c /etc/ModemManager/fcc-unlock.d/2c7c:6008

      What is the impact of this issue to you?
