Engadget:

The iPad mini and iPad Air Apple quietly announced ahead of its big March event will come with eSIM support. Cupertino’s latest iPad Pros have eSIM support, as well, but these new entries are the first non-Pro models with the feature. While the Apple SIM works similarly — and present in older non-Pro iPads — it’s only compatible with the tech giant’s partner carriers. By giving these devices eSIM support, they’ll be able to work even on the networks of non-partner carriers.

A small thing, but really important for folks who travel.
