How to Check Data Usage on an iPhone

This wikiHow teaches you how to view your iPhone's data usage since the last time you reset the data statistics.

Method One of Two:
Using Your iPhone's Built-in Features
Edit

  1. 1
    Open Settings. It's a grey app with gears that you'll likely find on the Home Screen.
  2. 2
    Tap Cellular. This option is near the top of the "Settings" page.
    • On phones that use a U.K. English keyboard, tap Mobile Data.
  3. 3
    Scroll down to view the "Cellular Data Usage" section. You'll see two options listed below this heading: "Current Period," which reflects all data usage since you last cleared your data usage statistics, and "Current Period Roaming," which shows data usage for areas in which your phone wasn't covered by the carrier (e.g., international travel).
    • "Current Period" data does not automatically reset for your billing cycle. You can reset your data usage statistics by tapping Reset Statistics at the bottom of the page.
  4. 4
    Scroll down to view a list of apps that use Cellular Data. These will be listed beneath the "USE CELLULAR DATA FOR" heading; any app with a green switch to its right is able to use data.
    • The number below an app's name reflects how many kilobytes (KB), megabytes (MB), or gigabytes (GB) that app has used since the "Current Period" was last reset.

Method Two of Two:
Requesting Information From Your Carrier
Edit

  1. 1
    Call your carrier's data hotline. While checking the data usage in your Settings will show you how much you've used, it won't show you what your limit is, and sometimes the date and measurement is off compared to your carrier. You can quickly check how close you are to your monthly limit by entering the code for your carrier into the Phone app:
    • Verizon - Dial #DATA and press the "Call" button. You will receive a text message showing all your usage details for that billing cycle.
    • AT&T - Dial *DATA# and press the "Call" button. You will receive a text message showing how much data you've used versus your monthly limit.
    • T-Mobile - Dial #WEB# and press the "Call" button. You will receive a text message showing how much data you've used versus your monthly limit.
    • Sprint - Dial *4 and press the "Call" button. Follow the voice prompts to check your usage for the billing period.
    • Idea (IN) - Dial *121# and press the "Call" button. You will receive a reply with your usage.
  2. 2
    Consider downloading your carrier's app from the App Store. Most cellular carriers have an app you can download to your iPhone; once you do so, you'll be able to monitor your data usage and plan information from within the app.
  3. 3
    Contact your carrier directly. If all else fails, calling your carrier's support line or going to your local carrier's store directly will allow them to tell you how much data you've used and how much remains in your current cycle, as well as upgrade your plan if you feel it would be beneficial.

  • How do I stop apps from using data on my iPhone?
    Answered by wikiHow Contributor
    • Go to Settings, then click on Cellular. Scroll down and you will see toggle switches. To disable certain apps from using data, toggle the switch next to the app you want disable. If the toggle switch is green (or dark gray depending on phone contrast settings) that app is using data.

  • What does 1.111 GB mean?
    Answered by Nathaniel
    • 1.111 GB (or gigabytes) means 1,111 MB (or megabytes). To provide references, one picture is usually 8 MB, and a full-size movie is around 1 - 2 GB.

  • Where on my iPhone will it show the quality of my connection i.e. 4G?
    Answered by wikiHow Contributor

  • Can I find out how many texts I have sent?
    Answered by wikiHow Contributor
    • Your service provider may have created an app that can be downloaded. Once connected to your number via a security code, the app can be used to monitor text, minutes and data usage. Not all providers use this, but search for your service provider in the app store or on their website for details.
    Thanks! 5 7
  • What number do I send the text to?
    Answered by wikiHow Contributor
    • You don't text a number. Rather, you dial the code as if you were making a phone call. Example: For AT&T, you dial *3282# and then press call. You will receive a message that says something like "Thanks! A message will be sent to your phone shortly."
    Thanks! 3 6

  • How do you check WiFi data usage on an iPad?
    Answered by wikiHow Contributor
    • Go to the "Settings" application on your iPad, and click "Cellular". There will be displayed the amount of "Cellular Data" you have used. Your data will be measured in "bytes" (e.g. 123MB). Depending on how much data you have used, it may measure it in GBs (Gigabytes). MB stands for "Megabytes" and there are 1000 MBs in 1 GB. Unfortunately, the iPad does not display WiFi specific data usage.

  • My plan says that I have sent 98 picture messages. How is this possible as I don't have 98 pictures on my phone?
    Answered by wikiHow Contributor
    • It tells you about the picture messages you've already sent. Maybe you sent 98 picture messages to a friend, and then deleted the pictures.
