How does eSIM work?

Question

mobile connection

Do I understand correctly that the operation of eSim completely depends on the quality of the Internet, and if I arrive in some village where there are cell towers but the Internet quality is poor, then I won’t be able to call normally? Those. Do you need a normal LTE connection for eSim?

Answer 1

No. An eSim is a chip in a phone that does the same job as a normal sim.
The Internet is only needed for installing the operator application and initial setup of esim

Answer 2

I haven't studied it, but I don't think so. The radio module just costs, it has a "memory". this memory is filled with what is on the sim card (and the sim card has its own memory and not only)
, in fact, it turns out a clone of the sim card
