Thanks; I should have mentioned that I do have an iPhone, and I have used IMS while ex-USA. I was concerned about the eSIM description saying calls were limited to Europe. Since frappant had said the eSIM was in an iPad, I assumed any call would need to be made from a tethered phone, and maybe that limitation would carry over. (Another possibility is that an eSIM in an iPad would have no call capability, even if the eSIM otherwise included it.)
