How to Fix a 'Not Registered on Network' Error on Samsung Galaxy

Check the SIM Card

If you’re encountering a “Not Registered on Network” error on your Samsung Galaxy, the first step is to check your SIM card. The error could be caused by a faulty or improperly inserted SIM card. Here are some steps you can take to troubleshoot the issue:

Remove the SIM card: Power off your phone and locate the SIM card tray. Use a SIM card removal tool or a straightened paperclip to gently eject the SIM card from its slot. Be careful not to damage the SIM card or tray.
Inspect the SIM card: Once you’ve removed the SIM card, examine it closely for any signs of damage or debris. Clean the card using a soft, lint-free cloth or a cotton swab slightly dampened with alcohol. Ensure that the gold contacts on the SIM card are clean and free from any dirt or residue.

If the issue remains, try the following additional steps:

Try another SIM card: If you have access to another SIM card, insert it into your phone and see if the error message disappears. This will help determine if the problem lies with the SIM card itself or with your device.
Contact your network provider: If the error continues to occur with a different SIM card or if you don’t have access to another SIM card, it’s advisable to reach out to your network provider. They can troubleshoot the issue further and provide you with assistance specific to your network and account.
