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. -- You received this bug notification because you are a member of Ubuntu Phonedations bugs, which is subscribed to ofono in Ubuntu. https://bugs.launchpad.net/bugs/1462208 Title: Roaming neccessary even in national home mobile network with two SIM cards. Status in ofono package in Ubuntu: Incomplete Bug description: 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.
