2. Remove and Re-Insert SIM Card

If you are still dealing with the network registration issue, then you need to consider the most obvious cause, which is an improperly inserted SIM card. 

Therefore, you need to remove the SIM card from the SIM card tray and insert it again. Also, check for any visible damages when you remove the SIM card. 

So, turn off your Samsung Galaxy. Then, remove the SIM card and check for damages. If there aren’t any, insert the SIM card back into your smartphone.

If the SIM card is defective, take your phone to the nearest wireless carrier store for a SIM card replacement.

3. Select Your Network Manually 

Modern Android smartphones including Samsung galaxy devices are configured to locate and connect to the proper carrier network automatically. 

Usually, this works out well for the users as they don’t need to go through all the trouble to set up the correct carrier network.

Unfortunately, when you are getting the Not Registered on Network error message, you may need to set the carrier network manually on your Samsung mobile. The steps below will show you how. 

  1. Launch the Settings app on your Samsung Galaxy mobile.

After the scan is finished, a list of all the available networks will be visible. Tap on the proper carrier network.

4. Change Network Mode 

The network registration error can also be related to the network mode. If you are in an area where your network is not available, you need to change the network mode to a more suitable type. Here’s how to do it. 

  1. Launch the Settings app on your Samsung Galaxy mobile. 
  2. At the top of the list, select Connection and then tap on Mobile Networks

  1. Launch the Settings app on your Samsung Galaxy mobile. 
  2. At the top of the list, select Connection and then tap on Mobile Networks
  3. Tap on Access Point Names

6. Update One UI 

An outdated operating system can cause a lot of trouble. If you are someone who never bothers to check for new OS updates, maybe it’s time to do so. 

Updating the Android OS or in the case of the Samsung Galaxy device, known as One UI, involves pretty easy steps. Let’s check them out.   

  1. Launch the Settings app and select the Software Update option.
  2. After that, tap on the Download & Install option.

Your Samsung Galaxy phone will start looking for the new One UI updates. If there’s an update available, download it.

Then, you will come across the Install option. Tap on it and the new version of the One UI will be installed which may fix the network registration error as well.  

7. Reset Network Settings 

At this moment, if you have successfully registered the network, then great. Unfortunately, the people who are not so lucky, have to go through an ordeal known as Resetting the Network Settings. 

This is a serious action and should only be used as a last resort. Executing a network reset will remove any saved Wi-Fi networks, saved paired devices, and all the customization. 

  1. Launch the Settings app and select General Management
  2. After that, tap on Reset and then tap on Reset Network Settings in the next panel.

In case none of the previous methods worked and you are still getting the “Not Registered on Network” error message on your Samsung Galaxy mobile, you’ll need to contact your mobile network provider

Now, contacting the service provider won’t be easy since you can’t make calls with your Samsung mobile. So, you can either visit the Mobile Service Provider’s store if it is nearby or call them using a different mobile.

  1. None of those fixes worked. 🙁 I live in a valley in the country, occasionally, we lose power. Every time this happens, I lose connection to the network. This time it has lasted going on four days. I have spoken to tech, spent 4 hours, still unresolved. Carrier says there is no reason I should not be connected. When I drive towards town, say at least a mile, I get connection back.

    • Hi Connie, sorry to hear that. It looks like you have a poor network coverage problem since your connection is back when you’re close to town.
