Hi all,
I am trying to develop a USSD client application /S60/, but I have some problem.

1) I need to prevent showing the default USSD. I managed to get the USSD response but the default USSD still appears.

2) I can't send a 'close USSD session' signal to the network. I found the "SendRelease" function under EtelMM API (RMobileUssdMessaging) but it's is not well documented and it crashes my application.

3) I managed to send USSD via AT commands but I have some problem sending via EtelMM API. The error code is (-6 An argument is out of range). This API is not well documented and it is difficult to resolve this problem.

I will appreciate any help on these problems.
Thanks in advance
BR,
Zoran Zlatanov
