Quirks - ESIM
To read about ESIM in general, see here. You have been redirected here because LineageOS builds for your device do not support ESIM functions.
Why is that?
While it is somewhat standardized, most devices have no open-source implementation of an enrollment application available. This means that maintainers are forced to utilize prebuilt applications from vendors/carriers, and the one for this device is incompatible with modern versions of Android. This might or might not affect you, depending on your usecase.
