Maybe I should give some details of what I'm trying to achieve. The
device we're building has 2 identical modems with fixed position on
USB. We also have the possibility to drive their power supply
independently and to swap the sim cards.
I need a way to know which one is modem A and which one is modem B
and I have no easy way of knowing the modem serial number or the
sim subscriber id beforehand. With an udev rule, I can easily set
a fixed name for the network interface of each modem. But under
ofono, I can't tell which modem is which. That's why I added this
Is there a way of knowing which physical modem ofono is refering to ?
I recognize that our case may not be the most common and I understand
that you don't want to abuse the Name property. Maybe exposing the
NetworkInterface as a modem property would be ok ? or exposing
a PhysicalName ?

Any update on this ? If Modem prefix is the only comment, I can
remove and resubmit the patch again. or is there more comments ?

Is' the first bit of the sim file status who indicates if a file
is valid or not. So a mask must be used to check this.

Since I'm using SIM card from my N900, I've disabled PIN code and ofono
worked properly and I was able to connect to my 3G operator (and see it
is locking me out, because I have a 3G phone subscription and it is
seeing a modem IMEI ...).
So, next part would be to get PIN code working ;)
