Having cellular data problems on your iPhone 11? Don’t worry – you’re not alone. Many iPhone users have experienced issues with cellular data not working properly.

The good news is, there are several things you can try to get your iPhone 11 cellular data working again. In this guide, we’ll walk through the top 10 solutions to fix cellular data not working on iPhone 11.

Fix Cellular data not working on iPhone 11

1. Check Cellular Data Settings

The first thing to check is whether cellular data is actually enabled on your iPhone 11.

Go to Settings > Cellular and make sure the Cellular Data toggle is switched on.

If it’s already on, try turning it off and back on again. Also check that you don’t have Low Data Mode enabled, as this restricts background data usage.

While in cellular settings, ensure Voice & Data is set to LTE/4G or VoLTE if your carrier supports it. You may also need to enable Data Roaming if you’re traveling internationally.

2. Verify Your Data Plan

No data plan, no data. Make sure your data plan with your carrier is active and you haven’t used up your monthly allotted data. Check the expiration date too.

Contact your carrier if you need to sort out any issues with your plan. They should be able to tell you the status of your data allowance.

3. Toggle Airplane Mode

A quick airplane mode toggle is an easy trick that often re-establishes cellular data connection.

Open Control Center and turn on Airplane Mode. Wait 10-15 seconds then turn Airplane Mode off again. This restarts all radios and usually fixes minor glitches. You can also go to settings to toggle airplane mode.

4. Check Date & Time Settings

If your iPhone date and time are inaccurate, it can prevent proper cellular network registration.

Go to Settings > General > Date & Time and make sure Set Automatically is enabled so date/time update over the cellular network.

9. Reset Network Settings

Resetting all network settings often resolves iPhone cellular data issues. Go to Settings > General > Transfer or Reset iPhone >Reset > Reset Network Settings.

This will reset WiFi, Bluetooth and cellular settings so you’ll need to re-enter passwords afterwards.
