Public bug reported:
Situation:
German mobile network operator "o2-de" (MCC 262, MNC 07) has merged with
another operator, "e-Plus" (MCC 262, MNC 03). Both operators have decided to
allow national roaming between their networks for all customers and for all
services (phone calls, SMS, data). The "other" network appears to the customer
with the name of their original, provider, but an added plus sign, e.g. if
you're an "o2-de" customer the e-Plus network will appear as "o2-de+" to you.
Expected behavior:
The bq Aquaris E4.5 roams into the other network if necessary and all services
are available. Ideally the device would not even go into "real" roaming mode
because national roaming is different from international roaming.
Actual behavior:
The bq Aquaris E4.5 roams into the other network and mobile data is deactivated
because the phone does not differentiate between national and international
roaming. The "mobile data roaming" switch has to be explicitely enabled, which
can cause problems for the user since the phone supports two SIM cards.
Complications:
- Both operators are changing their networks during live operation, other
phones have problems too.
- There is a long list of MVNOs and every one of them has to adapt to
the changes too. For example I have a SIM card by o2-de MVNO "netzclub"
in my bq phone and the network list now also shows the expected
"netzclub+" entry, roaming to it works. On the other hand I have a SIM
card by e-Plus MVNO "MEDIONmobile" in my Android Nexus 5 and there the
network list does not show the expected "MEDIONmobile+" entry, but just
an entry for "o2-de", and I cannot roam to "o2-de" even if I force it.
Notes:
II think there should be a similar situation in Sweden, where operators Tele2
and Telenor created a shared 4G network, and there are probably other countries
with comparable setups.
Debugging data:
- I added the output of /usr/share/ofono/scripts/list-operators on the bq phone.
- I added two outputs of /usr/share/ofono/scripts/list-modems on the bq
phone, once while connected to my original "netzclub" MVNO network and
once while roaming in the "netzclub+" network. All personal data has
been removed, but I am willing to share it in private.
