This is the kind of bug that would *maybe* be fixed by using ofono
rather than modemmanager in this instance.
While I understand it's unfortunate that the 3G doesn't work on that
device; there is not much I can do until this is fixed upstream for the
original Nexus 7. The Nexus 7 2013 might

Seems the original Nexus 7 is using the Infineon XMM6260 phone
controller, while the 2013 edition is using Qualcomm MDM9215M with LTE
support (seems to be a Gobi modem, which ModemManager might already
support).

OK, I've tried with both those network-managers, but kept getting that
same DBus error.
I had to tweak a few things to build the network-managers:
- added -u--ignore-missing-info to dh_shlibdeps in debian/rules, to avoid
missing info for a package (I think it was libmm-glib)
- removed
I think that happens because you need a network manager that is
compatible with the new ModemManager1 interface. Please take a look at:

I've talked to Aleksander and he said that his work is based on the 0.8
version of ModemManager and so this is the reason why I can't go on and
patch. The only solution is to make a custon version of ModemManager but
i don't know how to make. Is there anyone can make this porting?

Just checked the logs, thanks. So... ModemManager doesn't support Infineon
chipsets yet :-/ The call setup fails in the last step:
(ttyACM0): -- 'ATD*99***1#CR'
(ttyACM0): -- 'CRLF+CME ERROR: 4CRLF'
It's probably not hard to fix, though. A new plugin to handle the
Infineon-specific call setup

Have you considered purchasing the OTG cable? It allows connecting a
mouse and keyboard in order to use ubuntu in the traditional way. In
fact, this is the recommended mode of operation for the tablet, as we do
not expect to resolve the touchscreen issues before 13.04 is released.
