Today I was looking at my installed apps in the Aurora Store app and I noticed an installed app from Google called "SIM Manager".

I don't recall ever installing that app.

Strangely, although it shows as an installed app in the Aurora Store app, it does not show up as an installed app in the OS' setting for Apps.

I have Graphene's sandboxed play services installed, if that matters.

The phone (Pixel 6) has only one physical data only SIM.

Questions:

1) What is this app, and is it required for something?
2) How might it have been installed?
3) Does the Graphene sandboxed play services perhaps install and require it?
4) Why would it appear as an installed app in the Aurora Store, but not in the phone's native listing of installed apps?

Thanks in advance for any help to understand this better.

    In the "all apps" screen, hit the 3-dots menu button upper right corner, then "show system", then scroll down to "SIM Toolkit" -- there, you've found it.

    You didn't actually install it, and it didn't magically install. Its a system application that is delivered as part of the system image. The reason you are seeing an "update" for it in aurora is because there is a match in the package name.

    If you try to "update" it from aurora store, the update will fail because the signature does not match between the open source version you have installed as part of the system image, and the google version on store.

    Its nothing to worry about, just ignore it.

    The package handles some configurations related to the sim card which can be found through the DIALER; 3-dots menu button --> Settings --> Calls --> Call forwarding, Additional settings.

    Regged up here to also say thanks of your advices.

    E. Also to giving the blacklist option instead of just ignoring it for some of us pedantic people.
