I have never used an eSIM, but I’d like to know about them. Can anyone explain what are some reasons to use it?

I see, fair.

I’ve searched your phone on xda and it has some ROMs which support it. Not official LineageOS though 🥲

Aren’t almost all (at least photo editing ones) new Pixel 8 & Pixel 8 Pro features in the cloud? What things do you mean when you say Google is moving to local processing?
