Removing SIM Toolkit App 😡

de0u There are a fair number of threads on this forum involving somebody disabling or deleting some GrapheneOS system app and then finding out (sometimes months later) that it was needed for something.

DeletedUser19 Can you link? I tried to search but fount nothing.

I believe there are others.

DeletedUser19 I think its because your Carrier configured the SIM Toolkit app like this, as maybe It allows configuration by Carriers? So you should calm down and not be so desperate.

My carrier offers even more crap and when I start up my phone with a sim card it constantly shows their ringtone offerings, their social media page or offers. I don't want to see this, so I uninstalled this app via ADB.

Similarly Emergency because it was running in the background and therefore supported the modem. Airplane mode + this app = still a working modem.

DeletedUser19
In Security settings allow USB when unlocked
In Developer settings allow ADB Debugging

After install ADB Tools on your PC and do:
adb shell pm uninstall -k –user 0 unwanted-package

For remove and unwanted app. But be careful with other apps. You can see package name in bottom of app info (long press on app -> info -> scroll to bottom) like com.android.stk

DeletedUser19
replace unwanted-package with package name what you want. In your case SIM Toolkit. And yes it will remove only selected app.

DeletedUser19 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.

DeletedUser19 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.

DeletedUser19 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.

Back up your data before uninstalling system apps with ADB, you never know. I once uninstalled the home screen app on my previous samsung phone and my phone would not turn on. I had to factory reset it from the bootloader.
If you decide to uninstall the sim toolkit, keep in mind that if some bug happen later and you share it here you should report that you dont have this app.

@DeletedUser19 ;

The Simcard that your operator provides to you has certain operator-specific configuration options available within it. The "Sim Toolkit" application is there to query those configuration options and provide you with an interface for controlling them. The fact that you do not have a need for those particular configuration options is a function of your needs and what your service provider is offering. This doesn't mean that the application itself is useless or irrelevant to everybody else.

To get rid of it; sorry, that is not a supported function. Its built into the system image, so if you deleted it, it would cause your phone not to be able to boot.

secure_adict What carrier is that? (Just to know what carrier to avoid... FWIW Tmobile doesn't seem to subject me to any such junk with this app...)

blackbrook It's not US/EU operator

The SIM Toolkit App was installed on a friend's phone when he switched from T-mobile to AT&T. I have never seen this app on any Verizon Wireless based phones.

I don't have anymore the SIM Toolkit in my owner profile. I didn't change my SIM card.
Can I have a temporary access to this app ? It's due to a carrier or GOS change ?
