A long time ago when i was young and under 18 years old, made a small
USSD scanner by scripting modem interface to find out undocumented USSD
codes in operator's networks.
Found a lot of USSD codes giving "Syntax error" or "APPLICATION NOT
REGISTERED" or "Timeout" .
I always desired to have an USSD scanner and USSD parameter brute forcer
running directly inside a phone!
Another cool protocol like USSD is the UUS (User to User Signaling)
For sure it's not provided on mobile handsets, but who know, maybe some
networks have it by default allowed and two GSM subscriber could
exchange data for free :-)
