My problem with eSIM only is as a private network architect (working with open source LTE EPC stuff, for instance), I don't know exactly where the hell I can go to get an eSIM cut for our test networks. I can't figure out what eSIM personalization/etc providers will even take on such a small use case like myself where I just need to have an eSIM provisioned and get my authentication values to throw into the core network. This is going to screw over a lot of private LTE deployments on CBRS if there's no good way to cut eSIMs for this use.
