I'm seeing this peculiar message in syslog:
Oct 7 13:22:03 ubuntu-phablet kernel: [14655.999891] (0)[1956:rild][ccci/net]
(1)CCMNI0 close
I'm not sure why rild decides it suddently wants to turn ccmni0 off; but
that could well explain why there is no ip address on the interface, and
no routes to support setting the default gateway back to mobile later
on.
I don't think it's requested by NM; because there is earlier evidence in the
same log that when NM asks for it; you instead see a message like:
(0)[1956:NetworkManager][ccci/net] (1)CCMNI0 close
Along with NM's own logs for the disconnection; but I'll keep looking at
that side anyway.
Reassigning to Tony for now, until we can verify if it's rild that is
doing something it shouldn't.

Title:
turned off wifi to test 3g I see H in the indicator but I recieve
nothing from the system
Status in “ofono” package in Ubuntu:
In Progress
Bug description:
STEPS:
1. Install RTM88 on krillin
2. Use the system a litlle on wifi
3. Pull down the indicator network
4. Disable Wifi
EXPECTED:
I expect the system to seemless flip over to using 3g
ACTUAL:
I got no page (see screen shot) I tried pinging google and got ping: unknown
host google.com
ip route gave no feedback
phablet@ubuntu-phablet:~$ nmcli dev
DEVICE TYPE STATE
/ril_1 gsm disconnected
/ril_0 gsm connected
wlan0 802-11-wireless unavailable
Devices is correct.
The debug.txt in comment #3 clearly shows that mobile data is
connected via the list-modems output and list-contexts output. This
output also agrees with the nmcli output which shows /ril_0 as
connected. The smoking gun here looks to be the routing table, which
is empty.
