Hi again,

I've spent quite a bit more time investigating this and I think I've found another user hitting what appears to be the same issue:

https://community.particle.io/t/issues-provisioning-esim-following-latest-instructions/69652

Thomas was using Vodafone Germany rather than SMARTY UK, but the behaviour is remarkably similar. In both cases:

  • The download reaches the SM-DP+ server successfully.
  • Authentication succeeds.
  • The failure occurs during PrepareDownload (ES10b).
  • The carrier requires a separate confirmation code (ePIN / 4-digit confirmation code).
  • The current particle-tachyon-ril-ctl / lpa tooling doesn't appear to provide any mechanism to supply that code.

I also spent some time reverse-engineering the installed /usr/bin/lpa (version 0.1.6). It appears to be a Kigen sample LPA, and I couldn't find any supported mechanism for supplying a confirmation code (no command-line option, no interactive prompt, etc.). I also confirmed that running it directly against the eUICC works using the serial transport, but it still reaches the same ES10b failure.

So my question is:

Does the Tachyon currently support downloading carrier eSIM profiles that require a confirmation code (for example SMARTY UK or Vodafone Germany)?

If the answer is yes:

  • Is there a newer particle-tachyon-ril or lpa package that supports this?
  • Or is there another supported provisioning method that should be used instead of particle-tachyon-ril-ctl esim download?

If the answer is no, it would be really helpful to know whether confirmation-code-protected eSIMs are on the roadmap, as I suspect this will affect several European carriers.

Thanks! Hopefully Thomas's findings and mine together help narrow this down.
