Fix iPhone Cellular Data Not Working

The cellular network is indispensable for an iPhone. The iPhone relies on cellular data to access the Internet, make calls, and text messages, etc. If the iPhone cellular data is not working, it will bring colossal inconvenience to our life as we won’t be able to enjoy most of the features on the iPhone. You may think we can use WiFi to make the iPhone work instead of the cellular data. But none of us can make sure WiFi is always available.

A SIM card with a credit protocol or data on your iPhone is usually sufficient to use the iPhone cellular data. Make sure your iPhone is set up with the right data plan and turn on your cellular data by tapping Settings > Cellular > Cellular Data. You can check if your iPhone data is not working by disabling WiFi and trying to download a webpage, social media feed, or online video. If nothing is loaded, read on to learn how to fix cellular data not working on your iPhone 6/7/8/X/Xs/Xr.

1. Disable Airplane Mode

The airplane mode blocks your connection to cellular networks. So make sure you’ve turned off the airplane mode. If the mode is on, the iPhone network will not be available. When you see an airplane icon at the upper left of the screen, you can go to the Settings app and tap the toggle of Airplane Mode to turn it off. Alternatively, you can slide up from the bottom of the home screen to open the Control Center and tap the airplane icon to disable it.

2. Make Sure Cellular Data is Enabled

When you find the iPhone data not working, the first thing you should think about is to check if Cellular Data is enabled. Moreover, many users find sometimes the iPhone only works on WiFi because they have disabled the cellular data for specific apps. You can open the Settings app and click on the Cellular to check if the toggle of Cellular Data is on. Then scroll down to make sure the apps you want to use are allowed to use the cellular data.

If the Cellular Data has already been turned on and the apps you use are enabled to utilize the cellular data. You can try to toggle off the Cellular Data and on again.

3. Restart Your iPhone

If the cellular data is not working on your iPhone even though it is enabled, try restarting your iPhone. Some unknown software bugs and glitches can be the initiator of your iPhone not connecting to the cellular network. Most of the time, restarting your iPhone is enough to remove these bugs and glitches.

If you are using an iPhone 8 or earlier version, press & hold the power key until the instruction “slide to power off”appears at the top of the screen. If you own an iPhone X or later version, then press and hold either the volume button and side button until “slide to power off” is initiated. Then drag the slider from the left to right to shut down your device. Wait for a while, and then long-press the power key until the Apple logo appears in the center of the display screen.

4. Update Carrier Settings

It is a bit rare for the cellular carrier to update. Nonetheless, you can give it a try. What if it works! Head to Settings > General > About. If the cellular carrier settings need to be updated, a popup will appear on the iPhone screen. Then tap on Update to confirm.

If your iPhone data is still not working, you can resort to resetting the network settings. This will delete all your cellular data settings as well as WiFi networks settings, and return them to factory defaults.

After that, check whether the cellular data is available on your iPhone or not. If not, move on to the next method.
