Feature description

Copy contact(s) from phone to/from SIM. This feature is supported in some old apps ( [DumbphoneAssistant](https://github.com/yeriomin/DumbphoneAssistant, Copy2SIM) which are still -somehow- working on Android 13. P.S. I'm not which SIM slot refers the USIM in the menu, because when selecting USIM it just read the SIM1 (the Copy2SIM app is able to switch between SIM1 and SIM2).

Why do you want this feature?

This feature is important to copy contacts into a new brand sim.
