I think they've got a fair point, though, that a number of those issues with the eSIM reflect reliance on factors outside their control (for example, whether or not one's carrier has competent backend systems) where before swapping a SIM card was a physical action within their control. It's a frustrating feeling when a new technology takes something out of your hands in the name of convenience but, far from being seamless, actually introduces problems that are entirely out of your hands to fix.
