Hybrid Card slot SIM or SD Card, why not store SIM Card data embedded in the phone?

Hello,
Why it is not possible to hack a android phone to store the SIM Card data from the SIM directly in the phone?
I mean somthing like "E SIM" for poor ones. On devices with port for two SIM or one SIM and one Micro SD card that would be a great
solution to use dualsim and SD Card simultaneously. I heared that SIM cards have some sort of "Number" who can not be copied, is that the problem why that does not work?
