Browse Source 
Example:

./pySim-prog.py -p 0 -x 001 -y 01 -s 8988211900000000004 -i 001011234567895 \
	-k 8baf473f2f8fd09487cccbd7097c6862 --op 11111111111111111111111111111111 \
	-o 8E27B6AF0E692E750F32667A3B14605D -a 85524953 -n isim.test \
        --msisdn 0598765432100 --epdgid epdg.epc.mnc001.mcc001.pub.3gppnetwork.org

Note:

1. For Operator Identifier based ePDG FQDN must be in the format

epdg.epc.mnc<MNC>.mcc<MCC>.pub.3gppnetwork.org

2. For Tracking/Location Area Identity based ePDG FQDN must be in format

lac<LAC>.epdg.epc.mnc<MNC>.mcc<MCC>.pub.3gppnetwork.org

and

tac-lb<TAC-low-byte>.tac-hb<TAC-high-byte>.tac.epdg.epc.mnc<MNC>.mcc<MCC>.pub.3gppnetwork.org

and

3. For 5GS Tracking Area Identity based ePDG FQDN using a 3 octet TAC
