I've got the SM-T815 running CM13 on it. I've got a second SIM card (MultiSIM) from T-Mobile Germany, which enables me to use 4G from my existing contract without paying any extra for the second device. Unfortunately with T-Mobile Germany all MultiSIM cards receive incoming phone calls in parallel, which doesn't really make much sense with the tablet. All phone calls which I receive are tracked as missed calls on the T815, even when I received them on my phone.
With T-Mobile Germany there is no option to select a primary SIM card for phone calls, i.e. there is no option to disable telephony for a MultiSIM from the provider side. This is why I am looking for a way to disable telephony directly on the device without losing the 4G connection.
So far I have tried the following options:
I've had a look at the stacktraces just before the reboot and it looks like this issue might be easily solved. But before I dig in and go that route, I would like to double-check if I have missed any existing options. Is there anything I have missed? Did anybody solve this already?

So far I have tried the following options:
- Use airplane mode and enable Wifi: This is not an option as it also disables 4G data.
- Disable the Phone app: When disabling the Phone app, incoming calls cause the T815 to reboot (even worse than having missed call notifications).
