Fix the issue by restarting the device

Force restart your device by:-

Actually, these kinds of problems are caused by some bugs at times. Thankfully, the restart act has the potential to resolve these bug problems and glitches. After rebooting, you should no longer come across the error message. A force restart troubleshoots almost all the problems on your device related to phone and network services.

Fix the issue by updating your phone’s system software

Your Android device software might become outdated and require an update. The present version might contain a few bugs which are causing network issues and thus, the error message. Update your Android software to the latest version in order to get rid of such bugs.

Follow these steps to perform this method:-

  1. Open “Settings” on your device.
  2. Scroll down and you will find the “System” option. Tap to open it.
  3. Move down to find the option “System Updates”. Tap it.
  4. Wait for any possible updates. If it shows a newer update, just install it.

Updating your Android to the latest software can solve your problem at ease. Updates are completely free and you can choose the time when to update. You just need a stable internet connection to download the updates. Newer updates should not contain the bug which was causing the issue in the older version.

Fix the issue by manually selecting your carrier

Carriers play the most important part in providing network services. Android devices automatically determine and establish a connection to the carrier by default. But you have the alternative to set this manually too. It helps in case you are facing an issue with the auto-connected carrier network.

To do this, just follow these steps:-

  1. Open “Settings” on your device.
  2. You will find the “Wi-Fi & Network” option. Tap to open it. You can modify the SIM, mobile network, data usage, and hotspot-related things here.
  3. From the screen that appears, you have to select the “SIM & Network” option. You will see the SIM card options here. If you have more than one SIM card on your device, all of them are listed in order. 
  4. Select “SIM 1” to access the SIM settings.
  5. The “ Network Operators” option will appear. Open it.
  6. Toggle the “Choose Automatically” bar sideways to disable it. This will let you manually select the carrier network instead of the device doing that itself.
  7. Now your phone will display a list of carriers. Tap on the preferable carrier network.

Now your phone will get connected to the carrier available in the area of your choice. You will possibly not get the “Phone Not Registered on Network” error now.

Fix the issue by changing the preferred network type

Sometimes all network types are not available in a particular area. Some rural and semi-rural areas don’t have 4G and 5G towers to date. You have to change your preferred network type to 3G or 2G to work smoothly. Connect to the available carrier type in your area by:-

  1. Open “Settings” on your phone.
  2. You will see the “Wi-Fi & Network” option. Tap it.
  3. Open “SIM & Network” by selecting it.
  4. Select the “Preferred network type” option to view the options available. If you don’t get 4G or 5G, try switching to 3G. 

Now go back and check if the “Phone Not Registered on Network” error is coming. Probably it should not come. Android phones give you the liberty to choose the preferred network type according to your needs.

Fix the issue by using a different SIM card

Sometimes the phone network gets hampered if the SIM card has gone through some form of damage or disorientation. That’s when you might get this “Phone Not Registered on Network” error.

  1. Go and open the “Settings”.
  2. Tap on “SIM cards & Mobile Networks”.
  3. Find and select “SIM card provider settings”.
  4. Now navigate to “Mobile Networks”.
