First-hand experience tells me that Verizon has eSIM working, at least for their free trials. "You can participate in Verizon Free Trial with an eSIM-compatible smartphone." (https://www.verizon.com/support/verizon-free-trial-faqs/)

My phone doesn't support the bands necessary for VZ service, but it was worth trying.

I was attempting to get Airalo/Ubigi working and have seen many many people talk about how easy it was to get working on their iPhones.
