Keep
Android's default carrier settings, which tune calling, messaging and data behavior for your SIM's carrier.
Android (AOSP) package
Carrier Communications
Advanced: com.android.carrierdefaultapp Advanced Vendor documentation
The Android app that shows carrier notices, such as an out-of-balance warning or a carrier sign-in page. You can disable it, with a caveat: read what stops working first.
What it does
Carrier Communications is Android's default handler for carrier events. When a carrier signals that a prepaid account is out of balance or that data is blocked until you sign in or pay, it shows the notification and opens the carrier's portal so you can top up. It runs only when such a signal arrives.
If you disable it
Out-of-balance and carrier portal notices stop appearing, which matters mainly on prepaid plans; regular service is unaffected.
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)
adb shell pm disable-user --user 0 com.android.carrierdefaultappTurn it back on
adb shell pm enable com.android.carrierdefaultappThe stronger option removes it for your user only; the original copy stays on the phone and a factory reset brings it back. Prefer disabling: it is easier to undo.
