AnonUser932 None of those links have anything to do with removing SIM Toolkit.
de0u said right in the quoted text above the links that they're threads where people messed with system apps.
AnonUser932 This is my device, and I should have control over what is installed on it. I did not give permission for this bloatware to be installed on my phone, and it is not acceptable for the options to uninstall and manage permissions to be grayed out. I do not trust this app, I do not want it, and it is my device after all.
A few people here have already tried to advise against you messing with system apps, but you choose to do so anyway. Of course you have that right. But keep in mind that if you break something by messing with system apps, then nobody here can help you when things break.
AnonUser932 Confusing. If i run that code it will only remove SIM Toolkit? I'm confused.
If you're confused, then it's better not to use ADB.
