Roaming neccessary even in national home mobile network with two SIM cards.

[Michael Zukowski]

When using two SIM cards from different countries, here Germany and Ukraine, I have to activate "roaming" as dataconnection to obtain mobile internet access, even in my home network in Germany. As a negative side effect I will be unable after changing to roaming for data connection to receive calls and SMS on my Ukrainian mobile number, as the network provider immediatly refuses this SIM card. It seems that the phone tries to get for both SIM cards roaming access, for which the Ukrainian card is not registered.

Provider Germany: O2
Provider Ukraine: MTS Ukraina

I attach a screenshot to illustrate the problem. It has been made in my German home network, but it shows both cards in roaming mode. I have to activate roaming for mobile data networks, which causes that my Ukrainian number is refused, as it is only registered for data transfer in its Ukrainian national network.

At the end my smartphone turns to an ordinary mobile phone if I wish to operated both cards for receiving phone calls and sms.

Somehow my comment from yesterday was lost...

First, can you provide us with details of what version of Ubuntu you're running. If you can access adb, you can get detailed information from the command 'system-image-cli -i'. If not, please grab the version from "About this phone / Software / OS". Ex. 15.04 (r23).

Again, if you can use adb, please post the output of /usr/share/ofono/scripts/list-modems, and /usr/share/ofono/scripts/list-contexts. If not, could you attach a screenshot of the Cellular Settings?

If you can only use your Ukranian SIM for data when not-roaming, have you tried to select the other SIM for mobile data?

This is caused by bug https://bugs.launchpad.net/ubuntu/+source/ofono/+bug/1449990 .

O2 Germany recently merged with E-Plus and created a National Roaming Network out of both networks. Ubuntu has no support for National Roaming, and Michael seems to be in a spot where his phone correctly chooses to roam to the E-Plus Network (shows up as "o2-de+" in the screenshot) because of better coverage. So he ends up with both SIMs in Roaming mode.

As I wrote in the other bug, this will only get worse over time because we already have lots of markets with National Roaming, the bq phones have two SIM slots and the EU plans to abolish Roaming fees. So we need support for National Roaming in the short-term (Android has it already, so there should be source code lying around) and more fine-grained control over Roaming in the long-term.

Dear Tony (&Simon),

first of all, what works now: I operated both cards in roaming mode and have designated the German card for dataconnection. I choosed for the Ukrainian card the German vodafone network, the card is at least not refused from this network.

The OS version is: 15.04 (r23), last update 16.06.2015
I post the output of the requested command lines in a few minutes.

[Michael Zukowski (michael-zukowski)]

I tried now many time to copy the output from the terminal. But when trying to scroll up to copy the text, the terminal crashes and the phone eventually reboots. Next bug report? ;)
I attach a screenshot from the output of /usr/share/ofono/scripts/list-contexts, as you can see it is too long for sending the information via screenshot.

@Michael

The screenshot I was asking for was the System Settings - "Cellular" screen. If you can't run adb, don't worry about the output for the other scripts?

Also, per Simon's description in comment #3, unless there's any objection, I probably will make this a duplicate of bug #1449990.

Have you contacted BQ support about this problem?

[Michael Zukowski (michael-zukowski)]

@Tony: No I did not contact the BQ support. But of course I can do so. Please find belwo the cellular screen.

P.S.: No objections against a merging with bug #1449990.

I am currently on a business trip and with my "ordinary" USB cable I have with me, I cannot connect the Ubuntu Phone with my Ubuntu Laptop (14.04), it does simply not recognise the phone. (It is interesting that the same cable connects my phone with any windows 7 computer). I tried several things without success. But adb shell does not find the phone. So, I can earliest check it again in 7 days on my Ubuntu Laptop.

[Michael Zukowski (michael-zukowski)]

Finally: I own three Ubuntu Desktop Computers, but cannot run adp shell. Tried a lot from the ubuntuusers.de wiki. But it won t work. Nevertheless I am currently in Ukraine and use now mobile internet without roaming. It works well. So I strongly suggest that the user Sturmflut is right with his hint. It seems to be a provider issue with O2 in Germany. This case can be closed. Thanks for your suggestions so far.
