Effectively, imagine there's a SIM card soldered to the motherboard of the phone, you can then download an eSIM to it and the phone behaves as if it's a physical SIM.

In reality it's generally built into the modem and I believe they can typically hold multiple eSIMs. What I'm not clear on is if inactive eSIMs actually live in the hardware eSIM or if they get swapped in by the OS

    Depends on the phone. The newest ones let you use multiple ones simultaneously, one for calls/texts and one for data, for example. Slightly older ones only let you use one at a time, but they let you activate and deactivate multiple downloaded eSIMs.
