Not sure what carrier you're on but you can swap the esim to another device online on some of them. Otherwise a call to support might be required. I'm all for more space for the battery though. And traveling with a 2nd esim slot has been a lot easier to add a plan before I even get to my destination rather than buying a physical sim there.Just not that keen on losing a physical item here. Like when I took my iPhone for a new battery and it was easy to put my physical sim in an old phone whilst it was being done. Doubt it would be that easy with an esim.
