We can use the cellular data to check email, read news, or play games with our iPhone. And the different data plan offered by different wireless network operators varies from a few hundred MB to unlimited. To save money, many of us are using limited data plan. That is to say, we have to be careful not to exceed our monthly data plan, or we’ll pay overage fees. Though most carriers will send you a text message when you approach 100% of your data usage, sometimes this message may be late to prevent the overage. Therefore, you need to often check your data usage and limit cellular data use on iPhone 7/7 Plus.
How to Control Data Use on iPhone 7/7 Plus
- Go to Settings on your iPhone.
- Tap on Cellular > App using Wi-Fi & Cellular. Then you can check the data usage details of each app on your iPhone.
- If you want to stop an app from using cellular data, tap on the app, choose Off to prevent this app using Wi-Fi and cellular data or choose Wi-Fi to only allow it to use Wi-Fi.
Tip: the Wi-Fi Assist feature in iOS 9 and later lets your iPhone automatically use cellular data when Wi-Fi connectivity is poor, you can turn it off to save data use on your iPhone 7/7 Plus in Settings > Cellular > Wi-Fi Assist.
Set Data Limit on iPhone through Your Carrier
Some carriers allows you to put a hard cap on data usage from their end. For example, AT&T has a feature called Smart Limits that allows you to limit cellular data use on iPhone or Android phone and Verizon allows you to set data limits with FamilyBase. If it is necessary, you can contact your carrier to check if they have data limit service.
