Technically, I do not see why eSIM cannot be even easier than SIM swapping.

I go to a conference or hotel, and they can figure out how to have me login to the wifi and pay them. Or not pay them if I am a certain level member of their rewards program or part of a certain group of people attending the conference.

Other than legacy business contracts or lack of will by mobile networks to allow easy switching, it seems it should be just as easy to change which mobile network you are using.

As a side note, I love the cash grab by ATT/Verizon/Tmobile right now where changing your device entitles them to collect an extra $30 "activation" fee from you. Zero labor cost, almost zero compute cost other than changing IMEI in their database, and you still have to part with $30.
