eSIM seems to be good for the carrier (who doesn't have to ship anything or manage a database of SIMs for sale: provision on demand) but not for the customer.
Personally, I will not buy anything that doesn't offer an option for an actual SIM. SIM? Yes! eSIM+SIM? Sure! eSIM only? Nope.
It's like these services that ask "for your safety, please enter" (whatever, say the SSN): in general, when it says that, it's the opposite: it's for the safety of the service provider, putting the user at risk, and adding inconvenience.
Just like "The Democratic Republic of..." old joke: if it needs to say so and to add that in its name, it's likely neither a democracy nor a republic.
Except that as a customer I can buy cell service from my phone without having to anywhere or have anything shipped to me. eSIM is great for me personally. I had bought cell service on my main iPad (Mini 6) and it was seamless, then a few months later I tried to do the same on an iPad 6 (test/demo device) and realized I would have to get a real sim card so I just gave up and moved on because it wasn't that important and would have just been a "nice to have". eSIM makes my life easier though I understand international travelers might have some rough spots until the carriers get onboard (which they will because... Apple).
From Lord of War:
> "Every faction in Africa calls themselves by these noble names - Liberation this, Patriotic that, Democratic Republic of something-or-other... I guess they can't own up to what they usually are: the Federation of Worse Oppressors Than the Last Bunch of Oppressors. Often, the most barbaric atrocities occur when both combatants proclaim themselves Freedom Fighters."
