That looks reasonable yes.

atmodem driver for gprs_context uses TUN and talks PPP. Maybe your tun
module was not being loaded?
The swmodem driver is Sierra specific and uses the high-speed interface
(provided by a kernel module). This is probably what you want.

What do you do to make oFono recognize it? Likely the card is being
recognized first as a mass storage device. Do you have the latest
usb_modeswitch installed?
