just in general, it's difficult if your phone with an esim dies/lost/stolen (ie no access) to move the esim over. It's especially annoying if it just died, because instead of just popping the sim over you end up in a maze with the carrier (unless you are lucky enough to other lines on the account you have access to)

Went through the same last month. I had to both buy a new phone and still have my old one repaired to be able to authenticate to set up the new one.

I was a CyanogenMod user before switching to Pixel, and that experience was a monumental shove towards moving to Graphene.
