What is your card?
You just reported the ATR as "Phone SIM card" using
http://smartcard-atr.appspot.com/
<http://smartcard-atr.appspot.com/parse?ATR=3B1695D0016CFD0D00>
OpenSC does not support SIM cards.

I don't know if wpa_supplicant supports EAP-SIM using a SIM card.


Maybe it would be simpler to use a "FreeWifi" network with login + password
instead of the "FreeWifi_secure" network using EAP-SIM.
But you need to have a Freebox to get a "FreeWifi" account.

For the non-French readers free.fr is a French Internet Service Provider
(ADSL + optical fibre) and since some years also a GSM operator. The ADSL
boxes are call freebox and they provide a wifi access for all the Free.fr
users using login+password if you have a freebox yourself or EAP-SIM if you
have a Free.fr SIM card.
