If this actually happens to people in real life, let’s talk about it. All indications are that this problem isn’t a serious one yet.

New technologies often improve things in some way while introducing concerns and potential drawbacks in other ways. The question is whether, on balance, the new way is worth the risk.

My experience so far is that it is — it’s very convenient to be able to use a service like Airalo to order prepaid eSIMs for data service in foreign countries in advance. It makes traveling a joy now, and my wife is irritated a whole lot less by the prepaid SIM hunt I used to go on when traveling abroad. Plus no more tools or risking losing your SIM tray (or the SIM itself) when you swap it out on an airplane tray table.

It depends on how you define "serious". If it works for 99% people with a net positive and it doesn't work at all for 1%, is it serious enough to keep the old version?

My experience says that it will get steamrolled and the 1% left hanging, looking at significantly worse solutions, or none altogether.

A 1% failure rate would be huge. That's 1 out of every 100 customers. No rational carrier would tolerate that.

I know we all hate telcos and mobile phone carriers -- and a lot of their mistrust is quite frankly deserved -- but this seems like an edge case that most customers won't even run into. First they need to switch devices, which eliminates most customers, and then second, they need to experience some kind of failure on switch. If the failure rate is any higher than before, I would be surprised. But let's wait to see the data before we all go up in arms.
