I am quite annoyed by the people who don't see the issue with eSim because "they never had an issue" with it. It's like having one murder down your block and stating that you don't see the issue because nobody attempted to murder you so far. ESim are backed up as part of iCloud backups, had one dodgy carrier in Europe (Lyca) who never activated my eSim so I switched back to a new carrier but I had to get a transfer a…

eSIM is also great for travel. There's a lot of competition on price and it's easy to check esimdb to find the cheapest carrier that meets your needs for a given trip. Download the eSIM in advance and you're good to go as soon as your plane lands
Unfortunately there's not much competition on providing low-latency data connections, so most travel esim providers don't advertise where their connections route through. It's not great when you're travelling and all your connections to local sites get routed through and geo-located to a different continent.

Unforunately they're "downscaling" their operations in Europe, so I guess they're having trouble competing with other phones: https://www.gsmarena.com/is_sony_pulling_its_smartphone_busi...
They've always had uncompetitive pricing. I'm not surprised sales are low.
For what it's worth, this is entirely a carrier problem and has little to do with the technology. Various people and the article have outlined some bad experiences but to give a contrasting example: Digital Republic, a local MVNO here in Switzerland, allows you to replace your eSIM by simply logging into their web portal with TOTP-based 2FA and clicking a button. No SMS, no contact with support, no reidentification.…
The flaw with the technology is that it is designed so you need the co-operation of your carrier, when previously you did not. Indeed, for the first versions moving a sim profile could not even be initiated independently by a user, but required them to contact support. Now there is the "device change" protocol which can be triggered by an app on the phone, but I think it still requires the co-operation of carrier ser…
And it won't work if your phone is broken, while a regular SIM could still easily be removed.

I just bought a newer phone and was surprised to see even the ~$200 Samsungs were lacking a headphone jack. That threw them right out of contention, so I ended up getting a 2024-model Motorola (the 2025s were $50 more and reviews said they offered no meaningful performance boost).
I get it, but the quality of headphones with cords has gotten so bad that the male jacks wouldn't last more than a few months. My son has gone through an untold number of corded headphones because his school iPad is too locked down to use bluetooth ones.
Verizon (and their MVNOs) eSIMs are the worst. Registration is tied to IMEI and enforced via the eSIM's EID. You can't use one if those "physical" eSIMs because if you give Verizon a donor IMEI during registration, the EID of the eSIM doesn't match and activation is rejected.
Ended up switching to AT&T.
On the other hand, international roaming has become so much cheaper now that swapping SIMs when you travel is no longer necessary. The legacy carriers still try to fuck you over, but MVNOs and dedicated travel SIMs offer amazing rates: I can get a year of roaming across 120 countries for around US$15.

The problem with SIMs is that they aren't just credentials and config. They are full applications. Imagine if you needed to run a custom program to connect to every wifi network. It is bonkers. It is absurdly complex and insecure. A "SIM" should just be a keypair. The subscriber use it to access the network.
It’s more complicated because it has to include logic about which network to connect to and how to tunnel back to the original provider (or partner) while roaming. So it’s more like: which network to connect to, keys, fallback network selection logic and tunnel logic to get authorisation on a non-home network
