I had to _call_ my German provider to get a new eSIM.

Meanwhile, my carrier in Japan not only migrates eSIMs between phones with no issues; it even offered to migrate my wife's physical SIM to an eSIM when setting up a new phone; and it worked flawlessly.

The way my original eSIM here was provisioned was also surprising to me, in a "I didn't even know this is possible" way.

When signing up for a contract, I just put in my eSIM EID, and then a couple of hours later an eSIM was _pushed to my phone by the carrier_; without me having to do anything (other than confirming that I do want to install it). Lots of customer-facing telecom infra here is pretty bad; but the eSIM experience was as good as it gets.
