Review Cellular Data Usage on iPhone: How It Works

See exactly which apps are consuming your data. This page explains what it does, how to use it on an iPhone and which carriers it applies to.

I build Secret Codes: IMEI & Carrier, a free iPhone app with 317 checked codes and guides, including this one. If you would rather tap than memorise, get Secret Codes on the App Store.

What is Review Cellular Data Usage?

iOS keeps a running per-app total of cellular data since the counters were last reset. Note that it never resets itself — the figure is cumulative since you last cleared it, not since your billing cycle started.

Reset the statistics on your billing date if you want the numbers to line up with your carrier's.

How do I do it?

1. Open the Settings app.
2. Tap Cellular.
3. Scroll to the per-app list under Cellular Data.
4. Scroll to the bottom and tap Reset Statistics to start a fresh count.

Which carriers does this apply to?

Published for	any iPhone
Type	iOS setting
Good to know	Available on every iPhone. Figures are measured by iOS and will not match your carrier's billing exactly.

How Secret Codes helps

Secret Codes keeps this and every other entry a search away. Pick your carrier once and each entry says whether it is published for your line. You can save favourites, add a private note, and record whether a code worked on your line.
