I have just noticed that the output of monitor-ofono is part of the
logs, and I see that network status actually gets into roaming state.
But, it is in very short time windows:

2014-09-26 20:11:18,643 {NetworkRegistration} [/ril_0] Status = roaming
2014-09-26 20:11:19,323 {NetworkRegistration} [/ril_0] Status = registered
...
2014-09-26 20:16:31,743 {NetworkRegistration} [/ril_0] Status = roaming
2014-09-26 20:16:31,803 {NetworkRegistration} [/ril_0] Status = registered
...
2014-09-26 22:03:43,743 {NetworkRegistration} [/ril_0] Status = roaming
2014-09-26 22:03:43,779 {NetworkRegistration} [/ril_0] Status = registered
...
2014-09-26 22:10:58,077 {NetworkRegistration} [/ril_0] Status = roaming
2014-09-26 22:10:58,104 {NetworkRegistration} [/ril_0] Status = registered
...
2014-09-26 22:18:20,377 {NetworkRegistration} [/ril_0] Status = roaming
2014-09-26 22:18:20,411 {NetworkRegistration} [/ril_0] Status = registered
...
2014-09-26 22:26:05,503 {NetworkRegistration} [/ril_0] Status = roaming
2014-09-26 22:26:05,535 {NetworkRegistration} [/ril_0] Status = registered
...
2014-09-26 22:34:39,565 {NetworkRegistration} [/ril_0] Status = roaming
2014-09-26 22:34:39,598 {NetworkRegistration} [/ril_0] Status = registered
...
2014-09-26 22:53:31,359 {NetworkRegistration} [/ril_0] Status = roaming
2014-09-26 22:53:31,398 {NetworkRegistration} [/ril_0] Status = registered
...
2014-09-26 23:00:20,671 {NetworkRegistration} [/ril_0] Status = roaming
2014-09-26 23:00:20,732 {NetworkRegistration} [/ril_0] Status = registered
...
2014-09-26 23:07:00,161 {NetworkRegistration} [/ril_0] Status = roaming
2014-09-26 23:07:00,185 {NetworkRegistration} [/ril_0] Status = registered


This does not really affect the reasoning above, imho the main problem here is 
NetworkManager not attaching after coming back to registered state. However, 
these "Status" flash changes can be annoying and the user could potentially see 
a flickering roaming indicator in the GUI. I would like to get more traces for 
this, VĂ­ctor, could it be possible to do this:

$ phablet-shell
$ sudo su
# stop ofono
# export OFONO_RIL_DEVICE=mtk OFONO_RIL_NUM_SIM_SLOTS=2
# export OFONO_RIL_HEX_TRACE="" export OFONO_RIL_TRACE=""
# ofonod -n -d -P stktest,provision,sap,udev,dun,smart,hfp >& 
/tmp/ofono_log.txt &
# python3 -u /usr/share/ofono/scripts/monitor-ofono &> /tmp/monitor-ofono.txt &

walk around so the phone switches networks, and then attach the logs
here?
