From the article:

> While there are other eSIM adapters, the JMP adapter is the only one that doesn’t use a proprietary, closed source app.

What about managing sysmoEUICC1-C2G with EasyEUICC/OpenEUICC?

The manual mentions it includes EasyEUICC hash in an ARA-M slot, so it should work. ARA-M does not apply to OpenEUICC; as a system app, it can work with any esim.

https://www.sysmocom.de/manuals/sysmoeuicc-manual.pdf (p. 26)

The interface to configure an eSIM is standardized, there is no need to use the proprietary app. You might even be able to configure it with the software included with the phone OS.

That's not what's happening here.

The default phone OS software won't allow that. You either need a system app (like openeuicc) or a sim that has an app whitelisted so the OS will allow access (like this product uses)

These all seem quite expensive for what they are. I guess the demand is probably quite low, or are there infrastructure costs involved in supporting these?

Yeah, it's a demand thing for sure. Most of the competition is even more expensive.

How many esims does the JMP esim support? The esim.me chip supports up to 5.

There is no artificial limit, it's just down to how big the profiles are and the storage space.

With most profiles, it'll be more than 5
