This is a (rather complicated!) procedure to make calls with selection of the SIM card.
First my settings:
- In ‘Settings (System) - SIM-cards - Use SIM-card’: set to ’Always ask’
- in ‘Settings (Apps) - Phone’: disable Quick call
Now when you select a call history entry in ‘Phone (History)’ the contacts page opens. There you can select the phone number to call. Before to start the call it asks you to select the SIM card.
