Does your iPhone 11 Pro Max keep on losing its 4G LTE Signal?

Although smartphones have many features, it’s primary usage is for calls and text messages. This is an essential function that everybody needs right now especially that we are in times of crisis. You need this because, at any time, an emergency situation can happen.

But what if you are in the middle of a call and you got disconnected? Or what if you can’t send or receive important text messages? A number of iPhone users are alarmed by this issue.

We are going to discuss the causes of this issue in our article today. We decided to make an extensive guide on how to fix your iPhone 11 Pro Max that’s having a 4G LTE signal issue. Hopefully, we can turn these frustrations into a positive vibe at this time of crisis.

Let’s dive in!

 

 

1. Remove Application Conflicts.

It seems that the VPN service used by the third-party security software may affect the 4G LTE access. This may be a compatibility issue between the app and iOS.

You will need to disable your third-party security or VPN service app when using the cellular data in the meantime.

Of course, this is only a temporary workaround. You can use these apps again when using cellular data networks if the developers have debugged it. We suggest that you use a Wi-Fi connection instead when you want to use your VPN service app.

 

 

2. Use Wi-Fi Calling.

Another workaround you can use for the meantime is the ‘Wi-Fi Calling’ feature of your iPhone 11 Pro Max.

Since you are having issues with your cellular signal, you can utilize your Wi-Fi network to make calls. But this feature is not enabled on your device by default.

To enable this feature, go to the iPhone Settings, then tap on Phone, and then Wi-Fi Calling. Toggle the Wi-Fi Calling button to enable the feature.

Enter or confirm any details needed to finalize the process. If you encountered an error, make sure your carrier supports the feature and learn more about Wi-Fi Calling.

 

 

3. Refresh Data Network Connection.

There are times that a failed signal hand-over on your device can cause this issue.

This is a process where your device is trying to transfer connectivity from one cell tower to another. A lot of factors can cause this but one way to fix it is to refresh your network connection using Airplane Mode.

To do this, go to the Settings of your iPhone 11 Pro Max and tap on Airplane Mode to enable it.

Give it a minute and toggle the button again to disable it. You can also access this feature using your Control Center. Then tap on the Airplane icon to enable or disable the feature.

After this process, your device will be able to regain the 4G LTE signal.

 

 

4. Restart your iPhone.

If your iPhone 11 Pro Max keeps on losing the 4G LTE signal, it might be because of overloaded resources. This can happen when your iPhone has been running for a long time.

To fix this, you need to offload the accumulated tasks on your device. You can achieve this by doing a device restart.

To do this, press either of the Volume buttons together with the Side button until the power slider appears. Then drag the Slide to Power Off button to the right to finalize the process.

Give it a minute and use the Side button to turn back on your iPhone. After that, your iPhone should be able to regain the 4G LTE signal.

 

 

5. Remove and Reinstall Sim Card.

Another reason why you lose your cellular signal is due to SIM card misalignment inside your iPhone 11 Pro Max. This can happen when your iPhone suffers from physical impact.

To fix this, you need to remove and reinstall your SIM card to realign it.

Here’s how you can do it:

  1. First, go to the Settings of your iPhone 11 Pro Max, then General and then Shutdown. Drag the Slide to Power Off button to the right to turn off your device.

  1. Next, insert the SIM removal tool into the small hole on the side of your iPhone.

  1. Then, push it slightly into the hole to eject the SIM card tray and totally remove it from the iPhone.
  2. Now, remove the SIM card from the tray and install it again according to the shape of the slot.
  3. After that, reinsert the SIM Card tray back to the iPhone slot and push it until it clicks into place.
  4. Finally, turn back on your iPhone 11 Pro Max by pressing the Side button.

After this, your SIM Card should provide a correct profile for cellular network authentication. With this, you should be able to sync with the cellular network and regain your signal.

 

 

6. Check Signal with Another Device.

If you are still having issues with your cellular signal, try to check your SIM card using other devices. Remove it from your iPhone 11 Pro Max and insert it to other smartphones.

This is to make sure that you don’t have a defective SIM card.

One factor that is causing this issue is that your carrier might have poor coverage in your area.

Invite someone you know who uses the same provider into your area. If they too have poor coverage, you may want to consider another carrier with good coverage in your area.

But if they have coverage and you don’t, contact your carrier. They may need you to update the carrier settings on your iPhone.

If that doesn’t work, they need to debug the errors in their system or replace your SIM Card if it’s defective. But if the SIM Card works on other iPhones, the problem lies in your device.

 

 

7. Disable 4G LTE Temporarily.

If your issue is just with the 4G LTE signal on your iPhone 11 Pro Max, there is another workaround that you can consider.

You can choose to disable VoLTE and use 4G in the meantime. A number of iPhone 11 Pro Max users have chosen this option so they can just make a call or use text messaging.

To disable this feature, go to the Settings of your iPhone and tap on the Cellular option. Then, tap on Cellular Data Options and tap on Voice & Data. On that screen, disable the VoLTE option and choose the 4G connection instead.

With this setting, it would be much slower to connect to the internet but will be sufficient for calls and text messaging.

 

 

8. Update to Latest iOS Version.

There could be bugs on your current iOS version that is causing this issue. Glitches happen when new features are added to the system.

This means the new codes for the new features can sometimes cause conflict with the existing ones. Thus, the system becomes buggy and needs to be debugged by the developers.

To fix this, you need to update your iOS to the latest version so you can download the latest bug fix. You can do that by going to the Settings, tap on General, and then tap Software Update.

Follow the remaining instructions to complete the update process. If you have encountered errors during the process, learn more about what to do.

 

 

9. Reset Network Settings.

Corruption of network settings can cause this issue on your iPhone 11 Pro Max as well. Data corruption can happen when a certain process is terminated unexpectedly.

Processes like network communication is not an exception. But to fix it, you need to restore the network settings to the default state to rebuild it.

To do that, just go to the Settings, tap on General, and then the Reset option. On the list of options, tap on Reset Network Settings and provide your passcode if applicable.

All of your network profile connections will be removed and you need to set it up again. Observe if your 4G LTE signal is still abnormally dropping from time to time.

 

 

10. Reset iPhone to Factory Defaults.

If you are still experiencing the same issue, your iPhone core settings might be the one that is corrupted. This can happen on your iPhone too, especially if an update process failed or it unexpectedly powers off.

To fix this, you can reset your iPhone 11 Pro Max to the factory default settings.

This reset process is similar to the previous method. You go back to the Settings, tap on General, and then tap the Reset option. Instead of resetting the network, choose the Erase All Contents and Settings option. Provide your passcode if applicable.

After the process, try to set up your iPhone like it is new and observe if the issue still persists.

 

 

11. Restore in Recovery Mode.

The level of data corruption can happen up to the firmware level. If that happens, you need to restore your iPhone in recovery mode.

But this is only possible if you have a computer with a Finder app or iTunes app. If you don’t have one, proceed to the last method and let the Apple-Certified technicians do this for you.

Here’s how you can do it:

  1. First, make sure to backup your iPhone 11 Pro Max using iCloud or computer.
  2. Next, make sure you update your Mac for the Finder app or iTunes app in your PC to the latest version.
  3. After that, connect your iPhone to your Mac or PC using the USB cable.
  4. Then, open the Finder or iTunes application on your Mac or PC.
  5. Now, to put your iPhone 11 Pro Max to recovery mode, press and release the Volume Up button, and then press and release the Volume Down button. Then press and hold the Side Button until the recovery-mode screen appears.
  6. Next, search your iPhone on your Finder or iTunes app and click on the Restore option on the message prompt screen.

 

 

  1. If your iPhone exits the recovery mode screen, wait for the download to complete in your computer and then repeat Step 5.
  2. Finally, wait for it to finish the process and your iPhone will restart.

Now that you have restored your iPhone iOS, do not restore your iPhone from back up. To avoid conflicts, set up your iPhone like it is new and observe if you are still having iPhone 11 Pro Max 4G LTE signal issue.

Once resolved, you can restore your important data from the backup such as contacts and messages.

 

 

12. Get Help from Apple.
