Also, I'd like to emphasize that IMHO this should not be the default
in NM. Automatically selecting what APN to use should be explicitly
enabled by the user somehow. Companies doing custom setups with MM+NM
can enable this feature, even providing a "controlled" subset of the
mobile-broadband-providers-info database, and that specific use case
makes total sense.
