How to Fix iPhone 13 Pro Max No Service Error 2024

✅ We last checked all the steps in this guide on iPhone 13 Pro Max with 17.2.1 installed. The latest iOS version is 17.2.1.

The iPhone 13 Pro Max No Service error leaves you in a situation where you cannot make or receive phone calls or text messages. Connecting to cellular data is out of the question as well.

In this article, we will answer why the error is present and what you can do to eliminate it. 

Why Does My iPhone 13 Pro Max Say No Service or Searching?

Let’s start with the question WHY. It is hard to determine the reason given how many different causes there are. Knowing potential causes gives you the knowledge to troubleshoot the problem.

The No Service error could be the result of one of the following:

  • Carrier network issues
  • Network outage
  • Airplane mode
  • SIM card
  • Lack of updates
  • Damage

How to Fix an iPhone 13 Pro Max No Service Error?

Do not expect the problem to fix itself. You need to work on finding the solution to get rid of the No Service error on your iPhone 13. The suggestions below are precisely for that.

1. Check If Cellular Data Is Turned on

Let’s start with cellular data. Accidentally or intentionally, you might have disabled cellular data, and that led to a worse signal on the iPhone.

To check whether cellular data is enabled, open Settings, tap Cellular, and find out whether the feature is turned on or off. One thing to note for the British users. If your iPhone is set to British English, it will say MOBILE instead of CELLULAR.

2. Switch Airplane Mode on and Off

Tinkering with the Airplane mode is another potential solution to the issue. If you finished your flight and forgot to disable the Airplane mode, it is to be expected that there will be service-related issues.

Once again, go to Settings and switch the Airplane on and off a couple of times to get rid of signal issues. And to top it off, you can restart the device, which we will cover in the next section.

3. Restart iPhone 13 Pro Max

To restart iPhone 13, press and hold one of the Volume buttons and the side button simultaneously and wait for the power-off slider to appear. Drag the slider and wait for the iPhone to restart. It should not take more than 30 seconds.

To turn the iPhone back on, press the side button located on the right side and hold it until the Apple logo appears on the screen.

4. Take Out SIM Card and Insert It Back

Sometimes, the problem lies not in the connection or the device, but rather the SIM card. In this case, you also need to consider the fact that the dirt accumulates inside the smartphone over time, and if the substance ends up in the SIM card tray, then it makes even more sense to take the card and reinsert it.

5. Reset Network Settings

Network reset clears accumulated glitches, some of which might be the reason behind the No Service error. 

Open Settings, tap General, then click on the Transfer or Reset iPhone tab, and select Rest. You will see the option to Reset Network Settings. 

6. Check Date and Time Settings

You can try to set a different date and time setting. The idea behind this suggestion is that the device relies on the current date and time when it connects to a network. Thus, if the settings are not up to date, there might be some issues.

To set up the date and time on iPhone 13, go to Settings, tap General, and click on the Date & Time tab. Enable the Set Automatically option if it was disabled, and the smartphone will collect the information and adjust what is necessary.

7. Check Your Coverage Area

In case you end up in the middle of nowhere with no service connection, it is to be expected that you will not be able to make or receive phone calls. 

Your best bet is to find the closest location that offers phone service. Unless you find one, it is futile to expect a change.

8. Update Carrier Settings

The odds are that your current carrier has recently updated its network, which calls for an update on the iPhone as well. You want to sync your device with the current carrier settings to avoid potential issues.

First of all, join a Wi-Fi network. Then, open Settings, go to General and tap About. Here, you will see the option to update carrier settings if a new version is available.

9. Change Voice and Data Settings

Some voice and data signals also affect the overall network connection, meaning that you need to try to change the current settings. 

Access the Cellular tab via Settings. From here, you need to tap on Cellular Data and click the Voice and Data option. Now, you can make the changes by switching from 4G to 3G and vice-versa.

10. Reset All Settings

Resetting all the iPhone 13 settings might seem a bit excessive, but it is one of the go-to options when users cannot overcome network issues. 

To reset the settings, you will need to go to the General tab via Settings and tap on Reset. Then, select Reset All Settings and enter your passcode to finish the reset.

11. Update iOS

A missing iOS update is another example of a cause why you see the No Network error on your iPhone 13. 

As a rule of thumb, you want to keep iOS updated to benefit from the latest features and overall performance improvements, but not having iOS up to date is also known to cause network glitches.

Go to Settings, select General, and tab on the Software Update tab. If you see a new version of iOS available, tap to download it. 

12. Factory Reset

Think of the factory reset option as a way to give your iPhone 13 a clean slate. The method is similar to reinstalling an operating system on a computer.

Before you commit, make sure to back up the iPhone data on iCloud or an external storage accessory/device because a factory reset wipes all the data on the device.

Now, for the reset, open Settings>General>Transfer or Reset iPhone>Erase all content and settings.

13. Contact Your Carrier

Now that you know how to troubleshoot the No Service error on iPhone 13 Pro Max, you should be able to take care of the problem. And if the issue persists despite your best efforts, there are still a few options that have to offer.

Get in touch with your carrier. They might have some news about the network problems on their side, such as unforeseen factors affecting the signal throughout various areas, including yours. 

14. Get in Touch With Apple Support

Apple support is worth a shout as well. If you are not too tech-savvy and miss something, a person who is well-versed in iPhones might have an outside-of-the-box suggestion to give you.

15. Check for Physical Damage

The last bit of advice is about physical damage. If you recently dropped your iPhone on a hard surface or immersed it in water, it is possible that the accident affected the network service. 

Before you can solve the No Service error, you will first need to fix the iPhone’s hardware that was affected by physical damage.


All in all, there are multiple methods to troubleshoot the iPhone 13 Pro Max No Service error. We hope that this article helped you solve the error. The next time you see it on the iPhone, you will know what to do.
