https://launchpad.net/ubuntu/+source/systemd/204-5ubuntu20.10 adjusted the udev rules to prove some more drivers, perhaps one got in the way for you. Can you please install ubuntu20.9 (the old, working udev), activate the modem, do
lsmod > ~/modules.old dmesg > ~/dmesg.old . Then upgrade to current udev (i. e. ubuntu20.10), try to activate the modem (i. e. you get a failure), then do lsmog > ~/modules.new dmesg > ~/dmesg.new and attach modules.old, dmesg.old, modules.new, dmesg.new here?
