When the Interface or UpdateLocationInterface parameter is set to S6a, Radiator uses the Diameter S6a/S6d interface, defined between MME or SGSN and the HSS, for fetching authentication vectors from the HSS. String parameters S6aMCC and S6aMNC are required for formatting Diameter Visited-PLMN-Id attribute in S6a/S6d requests sent to the HSS. These parameters must be set to locally accepted values. They do not have a default value.

MCC must be 3 digits. MNC must be 2 or 3 digits. Leading zeros are required, as shown in the example below.

# MNC 244 is Finland. MCC 02 is currently unallocated.
