>working on my own eSIM implementation Please tell me you are serious about this. Tried looking into this earlier and found out that eSIM is extra proprietary, which means no hobby devices, like those 3G/4G/GSM connectivity Arduino modules.

I don’t know where you’re pulling these claims out from but here are the specs: https://www.gsma.com/esim/esim-specification/ https://www.gsma.com/esim/esim-specification/ In addition you can get ST micro data sheets for full blown electrical and mechanical data sheets for free

  Apple doesn’t use this eSIM spec, they have their own proprietary one.

      Of course not, because it’s a lie.
