How to Restrict iPhone Cellular Usage on Wi-Fi

iOS can help you restrict iPhone cellular usage on Wi-Fi and stay under your data plan limit so you can save on your mobile phone bill.  There are many ways to reduce the use of cellular data.  This article describes how you can reduce your data usage on your iPhone.

This article explains how you can restrict iPhone cellular usage on Wi-Fi and manage the use of cellular (portable) data on your iPhone.  You may find this article very useful, especially if you have an unlimited data plan.  I, myself, find that I am reviewing my monthly data.  After that, I only have one option to avoid incurring additional fees: I need to either reduce your data usage again.  If this is the case for you as well, it is time to make changes.  Fortunately, iOS provides great features to do this.

How to Track and Restrict iPhone Cellular usage on Wi-Fi

First of all, you should now know how much data you used.   First, open the Settings app, then find the “Cellular” menu.  Here, you can see a breakdown of the apps that used the most data and even disable mobile data for specific apps.

Disable Wi-Fi Assist

Apple says Wi-Fi Assist is designed to “use cellular data automatically when Wi-Fi is weak.”  However, oftentimes, you might think you only use Wi-Fi, when the Wi-Fi Assist is actually turned on while you’re burning your data.

To disable Wi-Fi Assist, go to the Settings app on your iPhone, then select “Cell” and scroll down.  There, you should see a Wi-Fi Assist switch that you can turn off easily.

This should also show you how much data you used through Wi-Fi Assist.  In my case, I burned 404MB of cellular data through Wi-Fi Assist, which can be very much depending on how much data is allocated to you each month.

How to Restrict iPhone Cellular usage on Wi-Fi and Control Data usage on your iPhone

Please see the following tips.  These tips will help you learn how to restrict iPhone cellular usage on Wi-Fi and save data on your iPhone.  Most of these tips, when applied, will help you restrict data requirements for Wi-Fi:

1.  Disabling / Enabling Data Usage.

On an iPhone, go to Settings> Cellular.  You can turn cellular data off and on.  There are other settings that you might want to explore.  If you scroll down, you can reset that by clicking Reset stats.

  • Click on cellular data options, and here you can enable LTE or 4G. There are three options here: (a) turn off (b) voice and data, selecting this option will allow voice calls and cellular data over LTE or 4G (c) data, this option will only allow cellular data over LTE.
  • You may also want to turn Data Roaming off or on.
  • You can also see how much data you used in a given period. Refer to the “Cellular Data” section.  You can reset these stats by clicking Reset stats (scroll down).

2.  See current data usage.

Some applications may use cellular data to connect to the Internet.  You can specify that.  If your phone is not connected to Wi-Fi, your phone will use cellular data.  You can also turn off or turn on cellular data for some applications.  You can use applications that use cellular data.  Find out why some apps use most of the data.  If you want to do that, just switch to this app.  When this is turned off, disabled apps will only use Wi-Fi to access the internet.

3. Turn off 3G and 4G data on your iPhone.

If things get really desperate, one way to keep your data down when it’s low is to temporarily disable cellular data.  This way, if you have a week or so until your contract is renewed, you can manage your use instead of running out of full.

To turn off cellular data, go to Settings> Mobile data (or Cellular data) and switch the Mobile / Cellular Data switch to the off position.

We also find this an easy way to conserve battery life – as opposed to turning on airplane mode, which saves energy but means that no one can call you.

4. Turn off autoplay videos on Facebook, Twitter, and Instagram

Facebook has recently added a feature to its iOS app, which means that when you scroll through your news feed, any of the videos posted will be streamed automatically – even if you’re not connected to Wi-Fi.  Obviously, this is not an ideal situation if you have a limited data allowance.

We recommend that you change your settings so that they are only broadcasted if you are connected to a Wi-Fi network.  Open Facebook and tap the three lines at the bottom of the screen.  Now choose Settings and Privacy> Settings> Videos and Pictures and make sure Autoplay is set to Wi-Fi connections only (or you can choose to never play videos automatically.)

Like Facebook, Twitter has an autoplay video feature that you can turn off in the app.  Click on your avatar in the upper left to view your profile details, then click Settings & Privacy> Data Usage.  Change the “Video Autoplay” entry  to “Only on Wi-Fi.”

However, the best policy might be to simply press the data saving key at the top of the data usage page – this turns off autoplay and reduces image quality as well.  There is a similar series of Instagram steps to pause video playback via your data connection.  Click on the Instagram gear icon and select Use mobile data and choose the option to use fewer data.
