The issue is often that the phones take a long time to download the apps the user needs, most of our users are on the go, and can't rely wifi, so they need mobile data, with a physical SIM we can easily tell them how to swap on their own, it is done in 10-15s, and can quickly be moved back, with an eSIM you have to dig through menus and hope it works, if not, the user is left with two phones without a SIM.
