How to Fix ‘Not Registered on Network’ on Android Phones


This annoying problem is often found in Samsung Galaxy devices, particularly when users update their Galaxy phone to the latest Android version and something went wrong. Their device is unable to detect the network and up comes the “Not Registered on Network” message. This occurs because after getting an update, your device IMEI number is changed to “SN 0000″ and it shows that your device SN number has been broken and need to be fixed.

Another reason is when you try to use the SIM Card from a new Network Provider and your Samsung fails to keep up when you’re trying to switch networks and needs a little help from you involving manually providing the new APN settings / Networks name in order to fix it.

In this situation the ‘Not registered on network’ error will show itself when you attempt to make a call or text. This occurs because your Service Provider is simply not notified of your IMEI number so on the screen you will see “Not registered on Network“. They even have the cheek to supply an OK button for you to press which does nothing to solve your problem at all! Frustrating, but don’t worry, we can solve this issue. First you should be aware that your phone is already unlocked. It’s not the case that you have to unlock your device in order to remove the ‘Not registered on Network’ error.

However, another reason for this error is if unfortunately your device has been Blacklisted, and by that we mean if your phone is reported as “Lost” or “Stolen” in the national blacklist database in your country. In this situation you have no choice but to take the following steps :

  •  Go to the police and report the scam,
  • Try to get your money back from the seller,
  • Change the IMEI of your Phone (which is illegal),
  • Sell your cellphone overseas.

Removing your Android activation lock

An activation lock prevents someone else from gaining access to your phone should it be lost or stolen. If you're returning, replacing, or selling your phone the lock should be disabled beforehand. If the activation lock is not removed from the phone it renders the phone unusable to anyone other than yourself.

Google and Samsung each have their own activation locks and offer different methods of removal. For Samsung phones, it is possible that both types of activation locks are present and you would need to remove both. 

In most cases, a factory reset does not remove the activation lock from the phone. For example, if the phone is the factory reset with the Google account still signed in, the phone will still ask for those credentials once it turns back on. Therefore it is safer for the account to be removed before the factory reset takes place to ensure your account is fully removed.

Note: If a Google account password is changed before performing the reset instead of being fully removed the message “Please sign in using one of the owners accounts for this device” will appear. This indicates the Google account on the phone is now locked for 72 hours and you must wait for it to reset.


Removing your Google activation lock from device settings on your phone

Depending on the exact model of the Android phone, the steps to remove your Google account may differ slightly. The general steps listed below should allow you to remove your Google account from your phone, but some phones may skip some of the steps.

  2. Tap Accounts or Users & Accounts.
  3. Select the account type, which in this case would be Google.
  4. Tap the email address.
  5. Tap the menu icon (three vertical dots) on the top right-hand corner.
  6. Tap Remove account.
  7. Confirm by tapping Remove account again.

If you are unable to complete the steps above, you would also be able to remove the Google Account from the phone by accessing your Google account online. 

Removing your Google activation lock online

  1. Log into your Google account.
  2. Once logged in, go to Device activity & notifications which is located under Sign-in & security.
