So, now if I let my phone fall and it cracks so that it doesn't work anymore[1] I can get an older one and move the physical SIM to it.
What happens with an e-sim?
I am stuck until I can (how?) contact the carrier or go to a shop where - maybe - they can transfer the e-sim to a new phone?
[1] or it fails for any other reason[2]
[2] and this usually happens on saturday, sunday or any other time when shops are closed
