I was trying to get NM SVN working using an Option UMTS card. After
figuring out that additionally to the capability "modem" (mentioned
previously on the mailing list) also the capability "gsm" is needed, my

What's the exact model of your card, BTW?  I'm trying to put together a
database of all the ones I come across.

That's the Vodafone Mobile Connect branded Option card. Not exactly sure, which Option name it has, one of the older ones with GPRS/UMTS only.


<?xml version="1.0" encoding="UTF-8"?> <!-- -*- xml -*- -->

             <append key="info.capabilities" type="strlist">modem</append>
             <append key="info.capabilities" type="strlist">gsm</append>

However, I needed to modify nm-gsm-device to work with the Option card to
try the registration again also for the reply "+CREG: 0,0". After the
second or third "+CREG: 0,0" reply, it then replies with "+CREG: 0,2" as
expected. This patch works for me:

I needed to tick "noauth" in gconf-editor, shouldn't this be the default
for dialup?

Currently I am struggling with the routes and the IP configuration, setted
after dialing in. They do not seem reasonable to me and I cannot reach the
DNS server nor the peer (

ppp0      Link encap:Point-to-Point Protocol
           inet addr:  P-t-P: Mask:

Kernel IP routing table

Has anyone a clue?

Thanks for NetworkManager and the GSM/UMTS support.
