using USSD-codes with Freerunner GTA-02

[Matthias Apitz]

Hi,

Some days ago I've read in a German computer magazine about Android
security bugs where URL's of the form tel:.... are directly send down
from the browser to the modem and mal ware web sides include so called
special dial codes (USSD-codes) to manipulate (invalidate PIN/PUK) your
SIM card or do even stuff more worse. So far so good (and Android users
deserve it).

The issue let me ask:

Is there a list of USSD-codes the modem of our FR understands,
for example to switch off calling party number presentation to the
remote side, or others?

Thanks
