Details
There is a change in the unlocking logic in ModemManager
1.18.4 [1]. This caused my modem to stop working [2].
This can be fixed with (according to the upstream issue [2]): $ sudo ln -sft /etc/ModemManager/fcc-unlock.d /usr/share/ModemManager/fcc-unlock.available.d/* I can confirm this fix works on Arch. I figure that these symlinks should somehow be handled by the package.

The Arch Linux package SHOULD NOT create those links, they must be created by each user under their own responsibility.
I've now pushed a shorter summary section, with just a few lines to read if you're not interested in all the details, please see https://modemmanager.org/docs/modemmanager/fcc-unlock/#short-summary
edit: Thanks for updating the documentation!
I'm sorry for that, the decision to keep things this way is fully on me exclusively. Forcing the users to manually setup the links is the only way we found to try to keep everyone happy, it's the "less bad solution". I know users are affected, but hopefully anyone looking for how to enable back the modem connection will be able to find that documentation page easily.
