USSD codes (Unstructured Supplementary Service Data) ??

Hi,

I'm running a golf gps app on my phone and wanted to block incoming calls whilst on the course as the app needs gps and mobile data enabled when running.

When I went to the call settings in the phone (Settings > Call > Call Barring) ... all of the barring options are Disabled except 'Outgoing International roaming' which is enabled.

When I try to disable it (or Enable barring 'All Incoming') the phone asks me to enter a 4digit password. I've tried the screen lock code, the SIM lock code, my mobile web a/c internet login code ... but they all result in an error, "Call setting error. Unexpected response from Network"

Then I remembered from a long time ago when I was on Vodafone, they had a long list of USSD codes (like *#06# for the IMEI number) for all sorts of stuff so I contacted my mobile network provider (HITS Mobile) and they said that the codes where phone and not network specific, so suggested that I ask Sony for the USSD codes for my phone (D2305)

So is this true and are there USSD codes for enabling and disabling call barring etc etc ??? If so, how do I access the full list ????

Thanks
