Why Is My Cellular Data Not Working on iPhone

There are several reasons why cellular data may not work on your iPhone. Some common ones include:

– Expired cellular plan.

– Low network coverage.

– Bug affecting cellular services.

– Network misconfiguration on your iPhone.

– Exceeded data usage limits.

– Airplane mode activated on your iPhone.

By addressing these potential issues, you can resolve the problem and restore your cellular data connection.

Cellular data not working on iPhone can be caused by various factors. Identifying the exact reason can be challenging. We have provided a detailed explanation of these factors and included instructions to troubleshoot them. Let’s get started.

How to Fix iPhone Not Connecting to Internet via Cellular Data

Here are twenty methods to troubleshoot mobile data issues on your iPhone. Start by disabling and enabling cellular data.

1. Re-Enable Cellular Data

This trick usually works well. If cellular data is enabled on your iPhone but there’s no internet, or you cannot use internet-based apps, try disabling and enabling cellular data. This has worked for me a few times when I had issues using cellular data on my iPhone. You should give it a try.

Step 1: Open Control Center on your iPhone.

– On iPhone X and later: Swipe down from the top-right corner of the screen.

– On iPhone SE, iPhone 8, and older: Swipe up from the screen’s bottom.

Step 2: Tap the mobile data icon to turn it off.

Step 3: Tap it again after a few seconds to turn it back on.

3. Check Signal Strength

Sometimes, the issue could be from your network carrier. If you are in an area where your network provider’s service isn’t available, the phone’s cellular data might not work.

A good way to determine network availability is to check the network signal strength on your iPhone. You can do that by looking at the network bars on your iPhone’s status bar, in the top-right corner of your device.

If there are no active network bars, you might have difficulties using cellular data on your iPhone. The same might apply if you only have one active network bar out of the four. To improve network reception, you can move around the area. You can also call your carrier to confirm the availability of network and data services in the region.

4. Check if Your Device is Compatible with 5G

If you are trying to enable 5G on your iPhone and it is not working, your iPhone may not be compatible with the latest 5G networks. Only if you are using iPhone 12 or a newer model, will you be able to access 5G.

5. Select the Right Network

If cellular data isn’t working on your iPhone, it could be due to weak network coverage in your area. In such cases, both 5G and 4G LTE may not function properly. Try switching to a lower-tier network. Although this will result in slower internet speed, it is likely the cause of the cellular data issue on your iPhone.

To fix this problem, follow these steps:

1. Open the Settings app.

2. Tap on Cellular.

If you’re having issues using SIM-dependent activities on your device, try ejecting and reinserting your phone’s SIM card. This SIM card troubleshooting fix could help with weird phone call issues or when cellular data isn’t working on your iPhone. Pop the SIM card out and put it back in, making sure it’s inserted properly. Many iPhone users have restored their device’s cellular data this way.

7. Restart iPhone
