iphone cellular data not working

Mobile phones nearly develop into portable computers, and iPhone is one of them. Our everyday lives are closely connected to the Internet, which makes it extremely annoying when iPhone cellular data not working. Most apps on iPhone, including Snapchat, YouTube and Facebook, need to be linked to function normally. No Internet connection nearly means that your iPhone has turned into a brick.

How can we get rid of the dilemma of iPhone no cellular data? To help those who are bothered, we provide 5 effective solutions to this problem.

1. Check Cellular Data Switch to Fix Cellular Data Not Working on iPhone

Making sure your cellular data may seem too ridiculously obvious to be an actual solution, but it can also be easily ignored.

Enter the settings and toggle the switch shown in the image below.

3. Force Restart Your iPhone When Cellular Data Not Working on iPhone

Long-time use of iPhone may result in cellular data not working on iPhone. Simple as it is, a force restart, also called hard restart or hard reboot, can be the solution to a variety of problems on iPhone. A force restart is different from a normal restart in that it is more complete and can reset the Internet options. To restart your device, you may refer to the ways introduced in the following paragraphs according to your iPhone model.

1) For iPhone 6s and former models:

Press both the Home button and the power button until the Apple logo appears on the screen.

2) For iPhone 7 and its derivative models:

Press and hold the power button and Volume Down button simultaneously for a minimum of 10 seconds until you see the Apple logo.

3) For iPhone 8 and later models,

Tap the Volume Up button and release it, then does the same to the Volume Down button. Then hold down the power button until the Apple logo appears.

4. Check Your SIM Card to Tackle iPhone Cellular Data Not Working

If you have been using a SIM Card for a long time, a couple of years for instance, it is possible that the card is damaged and the connection may be blocked. Another indication of broken SIM Card is that your iPhone will lose service from time to time. Another way to test whether your SIM Card is still functioning normally is to install it on other cell phones and observe its performance.

To deal with this situation, reinstall the SIM Card properly or simply replace the old SIM Card with a new one.

5. Resort to Apple Official Support to Fix iPhone No Cellular Data

If all the previous solutions fail to work, there may be software or hardware problems beyond normal people's problem-solving ability. The final and the best help we can get is Apple official support. Go to the nearby Apple outlet or customer service center. While fixing the iPhone on our own may either cause damage to the device or prove to be useless, the professional technicians can identify what's wrong with your iPhone, resolve it and tell you how to prevent the same issue from happening again.

The Bottom Line

We understand the disappointment and inconvenience of iPhone cellular data not working, and that is why we only provide the most effective methods. However, it would be the best if you can follow all these steps one by one patiently, which can ensure no potential solutions be ignored.
