Help me understand Sim Toolkit (STK) and its permissions

Schim1414

I am relatively new to GOS and Android in general. But, I have to clarify, I know that STK is an AOSP app and not an app pushed by the carrier. Also, I know that it can be disabled (I did that) or removed using ADB.

I noticed that STK received a lot of dangerous permissions (like access to camera, mic, contacts, etc) when I inserted my SIM card. All of these permissions are pre-granted and non-removable (greyed out)

So, many things are not clear to me and I have several questions about STK:

Can my carrier actually use those permissions to access my contacts, mic, camera, etc?
Does STK have some default set of permissions that it cannot function without? Is this set of permissions decided by the carrier?
I noticed that even after disabling STK, it still has fresh logs. Does disabling STK through ADB even do anything?

Thanks for the reply. I read those threads, and also found this one:

STK and its permissions are still confusing to me. It seems that carrier has some amount of control over STK app - it can change its name, display menus inside of it and request certain permissions. It is still unclear to me what exactly carrier can do with all the permissions it requested...
