Giessie, Feb 6, 2019 : Proposed function: Make it possible that you can set per user which simcard to use for outgoing calls. Contacts without a simcard defined will use the setting of the sim manager: Ask everytime, SIM1, SIM2. Overrulling, it must be possible for a user to overrule the preffered simcard for a contact when making a call. The contactsetting (for the simcard) will only be overrulled for that call. Making it intelligent, based on the incoming call history a proposal can be made for the contacts. For example a contact is always calling the user via SIM1, then there should be a proposal to make SIM1 for this contact the default. Who are the users: users with two simcards in their OnePlus phone. What is the user value: for known contacts the correct simcard is used straightaway for outgoing calls. Are there similair functions in the market? Yes, there are apps who can arrange this. From a security perpective I would not want to give an app from an external source controle over my voice calls.
