Dear folks,
I have just tested with my SIM card. When I type a USSD code, let's say *123#, it seems to me that an application is triggered, it asks me me to choose a language for example. After choosing a language, it asks me to choose a service, and show on.
I'm wondering whether I can use this kind of USSD code from my mobile phone to trigger my STK applet? If yes, can you share with me how to do this? of if no, can anyone explain to me where the triggered application above comes from?
Thank you in advance.
Best Regards,
JDL
