How to check data usage on iPhone 

In most parts of the world, cellular data plans are costly, and there is a cap on the data limit. Once you cross your usages, the additional charges are very high. To ensure you do not pay a hefty fee, you should regularly check your cellular data usage on your iPhone or iPad.

How to check cellular data usage on iPhone

  1. Open the Settings app. 
  2. Tap Cellular
  3. Under the Cellular Data section, next to the Current Period tab, you’ll be able to view your data usage.
    Those using iOS 16 or earlier will find this data next to the Usage tab.

Check data usage by logging into the carrier’s website or app 

You can also view the total cellular data that your iPhone has consumed from the website or application of your carrier. You might not be able to real-time stats, but you would still be able to determine how much data you are using.

  • The tab for System Services shows the amount of mobile data used for performing various basic tasks and services on the system level of your iPhone. When you tap it, you find how much cellular data Siri, Push Notifications, Software Updates, Backup, Documents & Sync, etc. have consumed.

If you find some apps are consuming too much data, you may turn off cellular data for those specific apps.

Also, scroll down to check the Wi-Fi Assist usage data. This handy feature automatically uses cellular data when Wi-Fi connectivity is poor. If you have a limited plan, make sure to turn Wi-Fi Assist off.

Finally, if you turn on the iCloud Drive toggle, your mobile data will be used to transfer documents and data when the iPhone isn’t connected to Wi-Fi. Since my plan has unlimited data, I have this toggle turned ON.

How to reset data statistics on iPhone 

If you have a monthly plan, like most of us, it is a good idea to reset the mobile data usage statistics on the initial day of your data plan’s term. Some carriers do this automatically. Once you reset it, you will be able to track and know your usage for the month precisely. To do so:

  1. Go to Settings Cellular
    Scroll all the way to the bottom. 
  2. Select Reset Statistics
  3. Again, tap Reset Statistics.

Can we check data usage statistics for dual SIM? 

Yes, we can monitor dual SIM data consumption. You may see how much cellular data you’ve used on your chosen cellular data number while using an iPhone with dual SIMs (physical and eSIM).

Are there any third-party applications to track data usage? 

The built-in data usage tracker is not very precise and doesn’t provide much information about how much data you use. Fortunately, you can track and personalize your data consumption with a few third-party programs. DataMan – Data Usage Widget, Data Usage Pro, and My Data Manager VPN Security are the applications I recommend.
