Meanwhile, small/private operators can't even leverage eSIM. We're trying to run a CBRS-based LTE deployment in-house and can't find a single company willing to work with us to get eSIM provisioning capabilities because we can't just make eSIMs like we can physical ones -- thanks to eSIM's fairly obtuse cryptogatekeeping by the GSMA, we can't do anything without their blessings.
Every single company that we've found that claims to do small-scale eSIM personalization/SM-DP/etc services just... won't answer our sales forms. Monogoto, Teal, Globalgig, Smartjac... nobody.
EDIT: To note, of course, if we were willing to spend tens of thousands directly with a manufacturer or company that actually does this stuff for a living (selling the whole core/radios/etc) I'm sure they'd bend over backwards, but we know how to deploy open5gs and buy eNodeBs that work in our system and deploy them as-is (up to and including abusing former Pollen Mobile gear) -- we already have a dozen or so devices on via physical SIM in our office.
