eSIM function not working on fairphone 5

I have a Vodafone DE eSIM activation letter with QR code and so on that works fine on an iPhone. But once I try it on my FP5 with iodéOS 7.4 I get the below errors.

Error code: ES10B_ERROR_REASON_UNDEFINED

Searching online I got the sense that I need to troubleshoot the OpenEUICC app. However it appears just in one place in my case: Settings → Apps → Pre-installed apps. There I can only uninstall and reinstall it. It cannot be launched, updated or interacted with any other way.

After uninstalling, rebooting, installing, rebooting now I cannot even try to add an esim as tapping Add network under Settings → Network & Internet does nothing.

Seems like I need to reset the phone or reinstall iodéOS from scratch before I do anything else. In the meantime: can anyone make sense of the error log?

OpenEUICC is not showing in your main “App Menu”? That is the tool you want, as iodéOS removes the Google eSIM manager and relies on OpenEUICC instead, so it not being found is certainly a problem. There are some devices that don’t support OpenEUICC and still need to use Google eSIM Manager, but I don’t think (?) the Fairphone 5 is one of those?

If it really is not there, please try to “delete” from “Preinstalled Apps > Reboot” and then add again to “Preinstalled Apps > Reboot” and then see if it is found in your App Menu.

I don’t recall ever seeing OpenEUICC as its own app. As I already described uninstalling and reinstalling it as you describe makes no difference.
