What is the purpose of enabling system settings in mobile data?

[sunking101]

Whenever I go into my settings if away from WiFi, a pop-up appears telling me that system settings doesn't have access to mobile data. Why should it have? I find this pop-up terribly annoying. I know that the simple solution would be to enable 'settings' to have access to my cellular data plan but why exactly does entering the settings of my phone require a data connection? I usually go into settings to enable a WiFi connection, or to check my battery usage. Thanks.

It needs it for things like iCloud access, and various other things, like deleting Safari data. It shouldn't use too much data if you turn it on.

my ipad shows 21 gigs used since last reset. which was august 2nd

my phone says 5.7 gigs since November 25th

both show "settings" only using 500k or less. i don't understand why someone would turn that off on cellular

theres also "system services" that can use a ton of data, if you are doing instant hotspot and itunes. that can use up a lot.
