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.

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.

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.
