Though I have and have read the mostly useless marketing material
touting the features of the Erricsson F3507g, I haven't been able to
find any real specs. It seems to be very similar feature-wise to the
Qalcomm Gobi-1000 and Gobi-2000 (MDM1000 and MDM2000 chipsets), but I
am yet to find any claim that the Erricson F3507g uses Qaulcom parts,
or for that matter, uses Qualcomm logic cores. It doesn't matter all
that much since the above tells me the device is most likely usable in
OpenBSD as is.

Two of the three umodem(4) have serial ports attached (ucom(4)) so all
you need to do is configure ppp(8) or pppd(8) to talk to one of those
serial ports (/dev/cuaU?). You should probably read the umsm(4) for
more info and an example chat script.

A lot of similar EVDO/HSPA devices are built in the same way in the
sense of providing more than one serial port, but only one of them is
usable with ppp/pppd. The other supposed serial port speaks a
proprietary protocol and is used for "management" purposes. Typically,
the proprietary protocol is either Qualcomm QMI or Qualcomm DM. Due to
various "leaks" (read: google android), portions of the proprietary
protocol have been figured out by the linux camp, but it's still a work
in progress. Some details were posted here:
