This realm demand depended on RADIUS server configuration. EAP-AKA
RFC4187 recommend (section 220.127.116.11) that realm should be generated
according to 3GPP TS 23.003.

Supplicant already contain necessary handler, which generate full
identity from IMSI (eap_sm_imsi_identity() function in
src/eap_peer/eap.c). But seems that this routine is never called when
you use SIM simulator. Try to configure realm manually.
For example instead of:
configure identity in following way:
identity="0232010000000000 at wlan.mnc001.mcc232.3gppnetwork.org"
Be careful, MNC in Europe contain 2 digits and you should put leading
zero before it, but in North America MNC contain 3 digits.
