+The ``core`` section of ``vars/main.yml`` is similar to that used in

+(``""``). As a general rule, ``core.ran_subnet`` is set to the empty

+Second, variable ``values_file`` is set to
+``"deps/5gc/roles/core/templates/sdcore-5g-values.yaml"`` by default,
+meaning simulated UEs uses the same PLMN and IMSI range as gNBsim.
+When deploying with physical UEs, it is necessary to replace that
+values file with one that matches the SIM cards you plan to use. One
+option is to reuse the values file also used by the :doc:`Physical RAN
+</onramp/gnb>` blueprint, meaning you would set the variable as:

+
+   values_file: "deps/5gc/roles/core/templates/radio-5g-values.yaml"
+
+That file should be edited, as necessary, to match your configuration.
