I got this message recently: "Carrier settings updates are small files that can include updates from Apple and your carrier to carrier-related settings, such as network, calling, cellular data, messaging, personal hotspot, and voicemail settings. You may receive notifications from time to time to install new carrier-settings updates."
What exactly does it mean? what data is being uplifted / shared / stored - to whom and for what purposes? It's too vague and I don't like it. Anyone?
