Apple has released a small iOS update that fixes some problems when activating the new eSIM functionality.

ios 12.1.2

The eSIM is a virtual SIM card that can be used alongside a physical SIM card, so you can use two mobile phone numbers in parallel. This option is available for owners of iPhone Xs, Xs Max and Xr.

With older models, call stability seems to be restored, some users had problems to establish a working connection. Apple doesn’t mention these changes explicitly, however.
