eSIM capable WWAN modules may cause SmartCard authentication issues:
Issue 1: Users confused by multiple SmartCard icons on the login screen:
Because the operating system recognizes the WWAN module's SIM card reader as a SmartCard reader, the user sees multiple SmartCard authentication options when logging in (if a SIM card is inserted). The user cannot determine which one to use for authentication.

Issue 2: eSIM conflicts with some SmartCard solutions:
Depending on the SmartCard solution being used, the eSIM may interfere with SmartCard authentication even if the user knows which SmartCard to select.
