@mikahdh. If rebooting your phone helps, it is not the same issue.

National Roaming not working

Think I've got the same problem. Since a while my phone (N4) hardly switches
back from 3G to 2G, reception is totally gone than.
Changed my provider a few months ago to eplus/O2. Probably the same time
troubles started. Usually I restart the phone.

As I remember, my O2 card and my Simquadrat card in the past didn't do the
automatic roaming, because the network was marked as illegal.
After manually choosing the network with my android mobile, the settings in the
SIM card were updated and automatic roaming for the partner network (E-Plus for

Adding ubuntu-system-settings : a solution for this kind of problems
would be to show all networks when scanning, even forbidden ones. The
phone would try to connect to that network if selected, and show an
error if it was not able to register.

Error messages produced by trying to register with “illegal” carriers is
already in the spec. Suggest bug 1211808 be re-opened and resolved
alongside this bug.

Another thing to note is that MTK modem could return different network
statuses for different technologies for the same operator (GSM and UMTS
networks for the same operator are showed as different entities by the
modem). ofono assumes that the forbidden/available status is the same
for different

Title:
@abeato, thanks a lot for investigating. My wife's SIM is indeed newer
than mine, but for sure not post-merger. It's some 5 years or so already
while the merged happened in the past half year. Anyhow, I agree, the
newer model obviously could explain the differences.
So far it is still working. I
@mzanetti, thanks for the logs. If the N9 shows "o2 - de" that means
that probably it considers that it is roaming, otherwise it would not
show the country code.
The fact that your wife's SIM shows both networks as available is
probably due to having a more modern SIM, which could contain
@mzanetti, well, if O2 does not appear in the list of operators either
you don't have O2 coverage or there is a problem with your subscription
and access to that network is forbidden.
You could check this executing
/usr/share/ofono/scripts/scan-for-operators /ril_0
If O2 is forbidden maybe you
Ok. This is interesting:
I've put the card in my old MeeGo based phone and here's what happens:
I don't yet know if automatic roaming works as I would probably need to walk
around out side and I haven't done that yet. However, going to system settings
-> cellular networks I get all 4 of the
Interesting. Indeed, a scan on the command line reveals this
Scanning operators on modem /ril_0...
[ /ril_0/operator/26203 ]
MobileCountryCode = 262
MobileNetworkCode = 03

now, look at that:
I've put my sim card back into the Ubuntu and surprise: o2 now shows up
in the cellular settings.
a new scan-for-operators gives this now (I've stripped the still
forbidden Telekom and vodafone networks):
phablet@ubuntu-phablet:~$ /usr/share/ofono/scripts/scan-for-operators
This smells like a modem FW issue: whatever the trick O2/symio are using
to allow this kind of roaming, the modem does not like it unless the SIM
has previously registered to that network. Not sure if we can do much
there but complaining to MediaTek. However, the logcat might be useful
to gather
Ok. Here's the output of logcat on my device when scanning for
operators: http://paste.ubuntu.com/12552919/
When the simyo card is in the MeeGo phone, I do not get a roaming
indication (although IIRC the N9 wouldn't show that even when
international roaming). The indicator text toggles between
It is difficult to say what might be happening. list-modems shows that
NetworkRegistration mode is automatic, and the modem is registered to
symio's Edge network (2G), although the preference is umts.
The issue here is that we do not have that much control over the modem

I've tried that before. There doesn't seem to be any showing up except

Maybe that's the issue?

It could be also a problem that this isn't a problem on our side. I have
heard from some E-Plus users that they have very similar problems while
being on Android devices. So it looks like the operators aren't very
well doing in merging both networks.
