Besides, e-sim doesn't really make the service work better.
eSIMs has lower component cost, size, weight, complexity vs physical SIMs. Also higher reliability, longevity, and security vs physical SIMs.
The cost savings are actually surprising - gold-plated contacts, packaging, distribution controls, etc - especially when multiplied by millions or billions of devices - though I'm too cynical to believe those savings will pass down to consumers.
The reduced physical bulk is also important. A SIM card slot is huge from the perspective of manufacturers (who've already shrunk it down to Nano SIM form factor, shrunk down to micro-USB ports, removed headphone jacks, etc). Slimmer phones and smaller toys (like smartwatches and coin-sized computer boards and chip-sized IoT gizmos) for consumers to enjoy.
The increased security comes from embedding. Maybe the scammers and hackers will figure out a way to exploit these things (as they always do, lol), but most of the criminal sorts are too lazy to develop the serious soldering and electronics skills needed to manipulate embedded logic parts.
eSIMs can also integrate all sorts of extended (black box) components/interfaces without worrying about standardized form factors and compatibility. If they want to build proprietary cryptocircuitry or extra biometric sensors or superior radiolocation hardware then they can simply modify the eSIM electrical/logic features as needed.
eSIMs will help populate the world with billions and billions of cellular-connected or cellular-capable devices - more devices than people - transponders, cameras, alarms, drones, vehicles, wearables, smart appliances.
So eSIMs won't make the phone service work any better. But they will make the phones themselves work a little better.
