Why is ‘General” under ’System Services’ using excessive cellular data?

I’m using iPhone 15ProMax at iOS 18.3.2 on Roaming, and System Service General eats up over 5GB of roaming data. Tried the support app, it’s just recommend update to 18.4

i have updated and the problem still persist.

Same problem with iOS 9 user decades ago, and here we are facing the same problem in 2025


at 18.3.2(Roaming) eats up half of my 10GB plan




At 18.4 eats up over 700MB over 1.1GB

what is this general system doing. It does not behave that way in my wife’s phone.

After hours of desperation and research, i THINK i’ve found the problem. Navigate to Settings > Apps > and check each and every app you don’t use and manually turn off “cellular data”. I’ve noticed “App store” automatic updates and cellular data were on although i have it off in “cellular data” and there are a TON of default apps we never use but are built-in and they ALL had cellular data ON. When I turned all of them off the “General” section disappeared from System services. I hope this was the problem!
