Not really. I was talking about the AP side configuration. You would
need to have anqp_3gpp_cell_net in hostapd.conf to match the SIM/USIM on
the station side. The function you referred to in wpa_supplicant was for
a case where NAI Realm list is used to select the network while SIM/USIM
would use this 3GPP Cellular Network information. Obviously you do also
need to configure the station side with a suitable SIM/USIM credential,
e.g., with that cred block here if you are doing this for testing
purposes without a real SIM/USIM, but that's a separate point.

EAP-AKA and EAP-AKA' do care about the SQN.
