I manage my own ASN, I've been thinking of branching out, experimenting by creating my own eSIM.

Given the huge number of virtual ISPs offering eSIMs at various prices, I mistakenly assumed it would be relatively easy to find documentation on how to do that (perhaps via some ISP selling traffic bundles to virtual ISPs); maybe someone can recommend any resources?

You'd be cutting deals with the existing providers, one by one, and acting as a reseller.

There'e also MVNO as a service providers. It's probably worth calling a few of them to see if that's a credible way to get started.
