No issues with eSIM on my end. I switched my number as soon as it was supported 3-4 iPhones ago and have migrated it myself between devices on each upgrade with no issues. Similar for my iPads. No issues moving eSIM between iPads on upgrade. Traveling has also been super easy. I use the app to provision an eSim for the country I'm going to and activate it just after I land or via the plane WiFi if available. The main issue with eSIM at the moment seems to be at the VMO level. A lot of VMOs don't offer eSIM because their parent carrier won't allow it. This is probably an area for the regulators to look into to make sure that the market stays competitive.
