Phone Services
Do not remove
The core telephony service that connects the phone to the cellular network for calls, texts and mobile data.
Android (AOSP) package
SIM Toolkit
Advanced: com.android.stk Advanced Vendor documentation
The menu that shows services stored on your SIM card by the carrier, such as balance checks or mobile money. You can disable it, with a caveat: read what stops working first.
What it does
SIM Toolkit shows menus and messages that come from applications on your SIM card. Carriers use it for services such as balance checks, prepaid top-ups, mobile banking and roaming tools, and some SIM messages pop up through it. Many US carriers put little or nothing on the SIM, so it often sits unused.
Also shown as STK.
If you disable it
SIM-based menus and pop-up messages from your carrier stop working, which matters only if your carrier offers services through the SIM.
How to disable it
On most phones Settings greys out Disable for this package, so ADB is the way to turn it off. The commands below work without root and can be undone.
Disable it (reversible)
