The Reason Why You Are Receiving the “Not Registered On Network” Error

If you notice a "Not registered on network" error on your Samsung Galaxy or Android phone, it may be because the software is not updated and your phone is running an earlier version of this software. "Not Registered On Network" error is a standard Android problem that occurs on T-MobileVodafoneAT&TAirtel, Straight Talk, Verizon and Rogers even after rooting your device.

Also, when your phone is locked to a carrier, it may display such an error. Unlocking your phone might help.

How To Fix The “Not Registered On Network”  Error on Samsung & Android Phones

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. 

Quick Check

Perhaps you accidentally enabled the Airplane mode on your phone, disabled Mobile data, etc. Before we go further, perform these quick troubleshooting steps:

  1.  Make sure the Airplane mode is disabled. You can also toggle the Airplane mode on and off
  2.  Toggle Mobile Data


Method 1 - Software Update

Make sure you are connected to a Wi-Fi network.

Software Update on newer devices

From your home screen, select :

  • Settings

Software Update on older devices

  • Navigate to Settings
  • Scroll down to the extreme bottom
  • Select Software Update

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.

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)  in conjunction.

  • A message will appear saying that you need to "Restart your Phone"- click it.
  • Finally, your Android phone should boot up with no errors.

Method 3 - SIM Card

If the methods above did not work, then the problem lies with your SIM Card.

First, try to reinsert the card. Open the SIM tray, take the SIM card and check it out. Make sure it is not damaged. If it is, contact your carrier for a replacement.

  • Dial (*#197328640#) or (*#*#197328640#*#*) from the phone dialer. Users are required to select the option 'Common.'
  • Next, select option #1, Field Test Mode (FTM). It should be OFF.' This process will restore the IMEI number.
