com.google.android.carrierconfig
Same as com.android.carrierconfig? Here’s that description:
Dynamically provides configuration for the carrier network.
The config contains: Roaming networks, Voicemail settings, SMS/MMS settings, VoLTE/IMS settings, and more.
If a carrier app is installed it will be queried for overrides to these settings.
Seems to run on boot and when you swap SIM card?
