I have tried to sen USSD message but I got always ERROR response
I follow the http://wiki.forum.nokia.com/index.ph..._USSD_commands
and also that example wich can be found on that wiki page.
I got ERROR response always.
I tested with command AT+CUSD=?
and got +CUSD : (0,1)OK
If I test AT+CUSD=1,"##21#",15 Response is ERROR
I tested with FP1 phone.
Can anyone use AT+CUSD command successfully with new 3rd FP1 phones?
