Understanding the Cause of the 'Not Registered On Network' Error

When a phone displays the "Not Registered on Network" error, it means that the device is unable to connect to the cellular network. There are several reasons why this error may occur, including SIM card issues, software issues, network issues, and hardware issues. The "Not Registered On Network" error is a standard Android problem that occurs on T-Mobile, Vodafone, AT&T, Airtel, Straight Talk, Verizon and Rogers.

SIM Card Issues

One of the most common reasons for the "Not Registered on Network" error is a problem with the SIM card. The SIM card may not be inserted properly into the phone, or it may be damaged. In some cases, the SIM card may not be activated, or it may have been deactivated by the carrier.

Software Issues

Software issues can also cause the "Not Registered on Network" error. If the phone's operating system or firmware is outdated, it may not be compatible with the network. In some cases, a software update may be required to resolve the issue. Additionally, incorrect APN settings can cause the error, preventing the phone from connecting to the network.

Network Issues

Network issues can also cause the "Not Registered on Network" error. If the network operator is experiencing a problem, the phone may not be able to connect to the network. Additionally, if the phone is in an area with poor coverage, it may not be able to connect to the network.

Hardware Issues

Hardware issues can also cause the "Not Registered on Network" error. If the phone's SIM card tray is damaged, the SIM card may not be inserted properly, causing the error. Additionally, if the phone's power button is not functioning properly, it may prevent the phone from connecting to the network.

In some cases, the solution to the "Not Registered on Network" error may be as simple as resetting the network settings or trying a different SIM card. However, if the issue persists, it may be necessary to contact the carrier or seek professional assistance to diagnose and resolve the problem.

How To Fix The “Not Registered On Network” Error

If you are experiencing the "Not Registered on Network" error on your Android device, there are several solutions that you can try to fix the issue. In this section, we will explore some of the most effective solutions to this problem.

Basic Troubleshooting

  • Ensure you have an active and valid mobile data plan with your current carrier and that your reception is strong.
  • Ensure that the Airplane mode is OFF. Sometimes, we accidentally enable this feature. Open Settings > Connections > Airplane mode. Toggle the switch button.
  • Reinsert your SIM card, check for damage, and ensure it is inserted correctly. If you have another phone around, place your SIM card in it and try to make a phone call.
  • Restart your phone.

Software Update

Make sure that your device is running the latest version of the Android operating system.

Software Update on newer devices

From your home screen, select :

  • Settings
  • Navigate to System updates
  • Check for system updates

Software Update on older devices

  • Navigate to Settings
  • Scroll down to the extreme bottom
  • Select Software Update
  • Please wait for it to reboot and complete the update
  • Finished!

If your device finds a new update, tap Download now. When it is finished downloading, a new screen will appear, alerting you that the software version is ready to be installed.

Rebooting and Reinserting

If this method does not work at first, try doing it again. Follow these steps:

  • Turn off your phone by holding the Power Button and the Home (or Volume Down Button) simultaneously.
  • Wait for two minutes while the phone is off.
  • If your phone battery is removable, remove it along with the SIM card.
  • Press and hold the Power and Home (or Volume Down) buttons together ten times.
  • Hold the Power and Home (or Volume Down) buttons together for 1-3 minutes.
  • Re-insert the SIM card and the battery (if removed).
  • Turn on your phone.
  • Once your phone is on, remove and reinsert the SIM card five times (skip this step if you have to remove the battery before removing the SIM card on some Android phones).
  • You will see a message asking you to restart your phone; click on it.
  • Your Android phone should now boot up without any errors.

Checking SIM Card

If your SIM card is physically damaged or not inserted properly, you may encounter network issues. Try removing the SIM card and inspecting it for any physical damage. If the SIM card appears to be fine, try inserting a different SIM card and see if the issue is resolved.

Access Service Mode

This method requires you to open the dialer first, following the steps below.

  • Open the dialer on your Android phone.
  • Enter the code ##4636## in the dialer.
  • This will take you to the Service mode.
  • Click on the top option which could be either "Device information" or "Phone information".
  • Next, tap on the "Run Ping test" option.

  • You will be prompted to reboot your device.
  • Click on the "Reboot" button and your phone will start rebooting.
  • Once the reboot is complete, check if the "Not registered on network" error is gone.

Troubleshooting Corrupt ESN

  • Turn on your device and go to the dialer.
  • Enter the code (*#06#) in the dialer to display the IMEI number. If it shows 'Null,' the IMEI number is likely corrupt.
  • Dial either (#197328640#) or (##197328640##*) from the phone dialer.
  • Select the option 'Common' from the menu that appears.
  • Next, select option #1, Field Test Mode (FTM), and make sure it's OFF. This process will restore the IMEI number.
  • Return to the key input and select option 2, which will turn off FTM.
  • Remove the SIM card from the device and wait for 2 minutes before re-inserting it.
  • Turn on the device and dial (*#197328640#) again from the phone dialer.
  • Go to and select Debug screen > phone control > Nas control > RRC > RRC revision.
  • Select Option 5.
  • Restart your phone.
  • After the restart, check if the 'Not registered on network' error is resolved.

Select Network Operator

If you are in a low reception area that doesn't support 5G or 4G, it's best to switch to 3G or 2G.

Go to Settings on your phone.

  • Go to Wireless & Networks Or Connections
  • Select Mobile Networks
  • Select Network Operators
  • Tap on Search Now
  • Then, Select your network.

You can also select "Choose automatically" to let your device select the best network mode based on your location.
