Select SIM (dual SIM) automatically according to adressbook called contact is out of (assign SIM to adressbook)

Dear developers,

I wonder if the dual SIM setting “assign adressbooks / contacts to a particular SIM” on a dual sim phone (mine is Xiaomi Mi6) to automatically being chooseen when a call is made is

  • in the pipe anyway?
  • needed from anybody else than me?
  • hard to develop?

On my old stock android 7.0 (on Moto G4 “athene” - patch level 2018/04) it was avaylable under Settings > SIM cards > Usage profile.

Thanks a lot!


I would need that functionality, too (Fairphone 3).
