eSIM activation not possible // SIM-Manager problems

Apps & Core Settings

Hello everyone,

I have signed a contract with Klarmobil (Vodafone) and would like to activate the eSIM.
Unfortunately, I get an error code when reading and manually entering the QR code/information.

iodé version: 7 (Android 16)
Smartphone: Fairphone 5
SIM Manager: OpenEUICC v1.4.0-iode.2

Here is a screenshot showing where the activation process gets stuck:

And here is an excerpt from the error code:

Error code: ES10B_ERROR_REASON_UNDEFINED

Last HTTP response (from server):

{
  "header": {
    "functionExecutionStatus": {
      "status": "Executed-Success"
    }
  },
  "transactionId": "xxx",
  "profileMetadata": "xxx",
  "smdpCertificate": "xxx"
}

Last APDU response (from SIM) is successful

Perhaps you have already struggled with the same problem or know how to solve it.

Best regards,

The SIM manager OpenEUICC has been updated to version OpenEUICC v1.4.0-iode.3.

Either the new version has fixed the problem or the “optional” confirmation code is not as optional as it seems.

The problem has been solved — I was able to activate the eSIM completely.

Sorry I don’t have experience with eSIMs, but I do see occasional posts about a user having trouble registering a new one. I think these have all been resolved meaning I don’t think there is an OpenEUICC issue, but sometimes a problem with how to use it etc.
