How can I explain that in english ?

So according to
https://code.google..../wiki/EapSimAka, EAP-SIM is a mechanism for authentication and session key generation using a GSM authentication algorithm on client and network side.
To make simple, the phone can connect to some wireless network without authentication, the sim card is the authentication protocol.
I try to add this in the wpa_supplicant.conf
network={
ssid="FreeWifi_secure"
key_mgmt=WPA-EAP IEEE8021X
eap=SIM
priority=5
}
but that doesn't work with our phone !
I hope you can understand what I mean !
