Why is My iPhone Using Data on WiFi?
As mentioned earlier, with iOS 9, Apple introduced Wi Fi Assist. If you have poor Wi fi, this feature allows you to connect to the internet using cellular data.
In theory, the Wi Fi Assist feature is quite helpful. You can enjoy an uninterrupted internet connection on your iPhone. However, if you don’t keep an eye on your data usage, you might end up with a hefty data bill from your cellular network provider or run out of your data limit.
Wi Fi Assist is designed to automatically not work on third-party audio and video streaming. Plus, it doesn’t provide data to background apps either.
Can I Be Charged for Data When Using WiFi?
When your iPhone switches you from WiFi to data, then you can be billed. It’s more likely to happen if you don’t have a data package or if your package is limited. Your data usage depends on the type of app you’re using.
There is one way you can keep track of your data usage. Here’s how:
- Start by going to Settings on your iPhone.
- Next, go to Cellular.
- Then, you need to tap on Mobile Data.
- Then scroll until you find System Services.
This will show how much data each app on your iPhone is using.

How Can I Tell If My iPhone is Using Data or WiFi?
Your phone informs you when you’re using Wi Fi connection and when you’re using data. For the former, you will see the WiFi sign on the top of your screen. On the other hand, for the latter, you will see LTE, 3G, 4G, or 5G, depending on your cellular network service provider.
If both the signs are appearing on your screen, it means that both features are being used interchangeably.
However, on some devices, only one may appear, which makes it more complicated. If you’ve noticed some additional data charges on your phone, it’s best to look into your data settings using the methods mentioned above.
