Hello Slishnevsky,
Welcome to the community!
Unfortunately, what you intend would not be doable. It is not possible to have the same number active on two SIMs (physical or eSIM) at the same time.
In theory, a SIM card could be cloned. However, only one of those SIMs could be active for making and/or receiving calls. In addition, it would not be possible to switch which SIM would be active.
Hope this helps 😀
Cheers
