Question

I am working on a project which needs to access "Sim Based Menu", I've read several documents listed with SIM Alliance websites, but I couldn't find any way to do that. Please help me if you know that how to access the SIM based menu(Service menu) using AT command or any other way.

I use SIM900 module for this task.

• EZ Pay

Answer 1

You should take a look at USSD specific AT commands for this. It's not really something to do with your SIM and more to do with your mobile operator. If you know the USSD commands that your operator supports you can send commands like:

AT+CUSD=1,"*111*#"

You will get then responses from the mobile operator which may or may not include a menu.

Answer 2

Using AT command we can access the "Sim Based Menu". "Sim based menu" has been installed to the Sim card so we have to use the STK(SIM Application Tool Kit) for the access this menu.

AT commands to operate STK functions.
