you might better introduce a OFONO_VENDOR_SIM900 quirk and use that in
the SMS atom driver. The phonebook support will also end up overwriting
this one later on. So I am not even sure this works reliable this way.
Might be just pure luck with the order of the atom.

why do you need the Nokia vendor quirk here. I think you better create
your own one.

Please indent these like the other plugins do. Look at ifx.c for
example.

Rest looks good to me.
