If you are a Samsung Galaxy S22 user and are experiencing the “Not Registered on Network” error, you’re not alone. This is a common issue that is a nuisance for a lot of Galaxy S22 users.

The “Not Registered on Network” error typically indicates that your device is unable to connect to your service provider’s mobile network. This could be due to a couple of reasons such as a problem with your SIM card, network settings, or a temporary outage from your service provider.

But don’t worry, in this guide, we will walk you through step-by-step solutions to fix this issue. Let’s dive right in.

Note: Solutions in this guide will work on any Samsung Galaxy S22 model (S22, S22 Plus, S22 Fe, and S22 Ultra models.)

Editor’s note: We created these instructions using a Samsung Galaxy S22 running Android 13. Depending on your device’s software version, some steps and menu positions may look slightly different.

Fix 01: Power Off and Restart the Device

When you restart your Galaxy S22, it clears out minor software glitches and temporary bugs that may be causing network registration issues.

Therefore, try restarting your Galaxy s22. Here’s how you can do that:

1. Press and hold the Power button and Volume down button simultaneously until the power menu appears on the screen.

2. Tap on the “Power off’ option.

3. After your device has completely powered off, wait for a few seconds.
4. Now, press and hold the Power button again until the Samsung logo appears on the screen.

Once your device restarts, check if the “Not registered on network” error has been resolved.

Fix 02: Re-insert the SIM Card

One of the common reasons behind the “Not Registered on Network” error is a loose or improperly inserted SIM card. 

Simply put, the SIM card is your gateway to the network. If it’s not properly placed, your device will fail to register on the network.

Therefore, follow the steps below and re-insert your SIM card:

1. Turn off your device.
2. Remove the SIM card tray: Locate the SIM card tray on your Samsung Galaxy S22. Then use the SIM card removal tool (or a small paperclip if you don’t have the tool) to eject the tray.
3. Check the SIM card: Look for any visible signs of damage. If the SIM card is damaged, you may need to replace it.
4. Re-insert the SIM card: Place the SIM card back into the tray. Ensure that it fits perfectly and that it’s not loose.
5. Insert the SIM card tray back into the device.
6. Turn on your device.

Fix 03: Clear “SIM Toolkit” App Cache

The SIM Toolkit is a system service (part of the operating system) on your Samsung Galaxy S22 that provides additional features and services on your SIM card. It stores SIM information and controls network registrations.

Sometimes, the data stored in the SIM Toolkit app can become corrupted or outdated, which may cause the “Not Registered on Network” error. Clearing the app’s cache can help resolve this issue by removing the temporary data and allowing the app to start fresh.

Here’s how you can clear the SIM Toolkit app cache:

1. Navigate to the Settings menu on your Samsung Galaxy S22.
2. Scroll down and tap on Apps.
3. In the list of apps, find and tap on SIM Toolkit.

4. Tap on Storage.
5. Tap on Clear Cache.

After you’ve cleared the cache, restart your device and check if the network registration issue has been resolved.

Fix 04: Check If the Service is Down

Before delving into more technical solutions, you need to ensure that the “Not Registered on Network” error isn’t due to a service outage from your network provider. 

Network providers occasionally undergo maintenance or experience unexpected issues that can disrupt their service. During such times, your Galaxy S22 may not be able to register on the network, thus leading to the error.

To confirm this, you can reach out to your network provider’s customer service. They should be able to inform you if there are any ongoing issues or outages in your area. Alternatively, you can also check their official website or social media platforms for any service disruption announcements.

If there is indeed a service disruption, you’ll have to wait until the network provider resolves the issue. If not, you can proceed to the next solution to fix the “Not Registered on Network” error on your Galaxy S22.

Fix 05: Register Network Manually

In some cases, your Samsung Galaxy S22 might fail to register on the network automatically. This could be due to a temporary glitch in the system or a problem with the automatic network selection feature. 

When this happens, manually registering the network can often solve the “Not registered on network” error.

Here’s how to manually register your network:

1. Open the Settings.
2. Scroll down and tap on Connections.
3. Tap on Mobile Networks.
4. Tap on Network Operators.
5. Now, tap on Select Manually. Your phone will start searching for available networks. This might take a few minutes.
6. Once the search is complete, a list of available networks will appear. Select your network provider from the list.
7. Wait for the phone to register on the network. If successful, you will see your network provider’s name at the top of your screen.

Fix 06: Reset Network Settings

The “Not Registered on Network” error can also be a result of incorrect or corrupted network settings on your Samsung Galaxy S22. 

This can happen due to a software glitch, a recent update, or because of misconfigurations. Therefore, resetting the network settings is what you need to solve this issue. Here’s how to do it:

1. Go to Settings > General management.
2. Tap on “Reset”.

3. You will see a couple of reset options there. Tap on “Reset Network Settings”.

4. Confirm.

Once it is completed, restart your Galaxy S22 and then it will have fresh network settings. Now, try to connect to your network again.

Fix 07: Try a Different SIM Card

If none of the above fixes worked for you, it’s possible that there is no network coverage for the current Network provider in your area or the SIM card is not working.  In such cases, trying a different SIM card from a different network provider will resolve the “Not Registered on Network” error and help you to determine the real culprit behind the issue.

If the “Not Registered on Network” error disappears with the new SIM card, it’s likely that the issue was with the original SIM card. You may need to contact your previous network provider for a SIM card replacement.
