Sure:
Read the specs for USSD, implement them and submit the patch :)
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)
http://www.turkcell.com.tr/c/oth/terminalpdf/23087-800.pdf .
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 :-)
