AFAIK eSIMs are implemented using a reprogrammable SIM chip residing in the device, and “applying” a saved eSIM (or installing one) means reinitializing it with the SIM’s parameters. I think it’s even implemented somewhat closely to a physical SIM.
Regardless, you need your carrier to support phone eSIMs and one of several registration methods: app, QR code, or manual parameters. (because some carriers support data-only eSIM for smartwatches)
But given this new eSIM push (and that non-US iPhone 14 models will keep the SIM slot) I think a lot more carriers are going to work towards this now. One of the 30 shown in Apple’s event is an Israeli carrier and they’ve been dragging their feet on eSIM for years, only doing the bare minimum for Apple Watch and Galaxy Watch.
