Could this Esim adapter from JMP somehow be used for the Librem 5?
On the face of it, it should work. You want to stump $50 to find out?
(It is my assumption that you would want the associated USB reader, rather than provisioning via an Android phone. With luck, with a USB-C to USB-A adapter and assuming that the associated USB reader is USB-A, you should be able to provision the eSIM adapter directly on the Librem 5 before powering off and moving the eSIM adapter from the USB reader into the SIM slot.)

Also, the JMP people are very responsive in their official XMPP channel, so if you want any definite answers from them, I recommend joining and asking.
Yes, this has been my experience as well. Very responsive.
Did anybody yet find information about using more than one eSIM stored on the jmp.chat eSIM?
I could be wrong, but I think the nature of embedded SIMs dictates that only one can be “active” in a SIM “slot” at any given moment , same as with a physical SIM (Dual SIM/Dual Standby devices notwithstanding).
JMP have said their adapter can load as many SIM profiles as will fit in the 420KB storage space, but I assume you would have to switch between them, and would not be able to run more than one from the same adapter card at the same time.
Yes, that’s what I thought about, too. But that wouldn’t be too bad. The switching from Linux would be a good start.
Sure, it would be great to somehow being able to use different eSIM for different purposes (data, voice).
I guess I’ll have to wait for mine to arrive and look into the software available.
With a device that has two physical SIM slots, I suppose you could buy two eSIM adapters from JMP and insert them both, gaining the ability to use two different pools of data for different purposes.
Sadly, the Librem 5 doesn’t have two physical SIM slots, though.
(Nor a single, international modem, for that matter… as dual SIM phones are also useful for travel.)
