No DNS servers into /etc/resolv.conf for Mobile Broadband.
This is evident from the debugging output that follows further down: Right after the line
         remote IP address 10.64.64.64
there should have been two lines with DNS server info:
         primary DNS address 195.67.199.18
         secondary DNS address 105.67.199.19

Found this bug in Jaunty network-manager_0.7.1~rc4.1.cf199a964-0ubuntu2 source

NetworkManager.c, line 55
#define NM_DEFAULT_PID_FILE LOCALSTATEDIR"/run/NetworkManager.pid"
/etc/init.d/NetworkManager, line 28
PIDDIR=${localstatedir}/run/NetworkManager

That puts the .pid file in /var/run/NetworkManager rather than /var/run and locks up any start/restart

Modify the init.d file to:
PIDDIR=${localstatedir}/run

A quick fix, at least in Jaunty.

Thanks for the hint! I will look into it.

But my experience from 4 computers is that in Jaunty (9.04) it works
perfectly right out of the box, but in Karmic (9.10) it does not work.

It is sad to have, for the first time since I started with Linux in
1995, machines without Internet connection :-(

Should be fixed in Precise.
