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

We kept getting the ‘Not registered on Network’ message when trying to make calls. Many times the network connection was lost for a while. Then we realized by trying to make a call that for a period of time people were unable to get a hold of us or send text messages. We tried everything to try to resolve the issue, and ultimately we replaced our phones with another Samsung Galaxy S5. Guess what, the issue is still there and we still get ‘Not registered on network’ errors. Is this an Android issue or an Android issue? It’s no surprise that Google said that it’s a T-Mobile issue and not an Android issue. Please help!”

 

Every week, no, make that every day, at code4gsm, we get customers writing in with a variety of problems relating to any number of different cellphones. In this article we look at a problem that occurs most often with Samsung phones but can apply to other Android phones in general. First, to acquaint you with the problem, here is a typical customer complaint:

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. Please take note of the following   models:

  • Galaxy S7 Edge
  • Galaxy S7
  • Galaxy S6 Edge
  • Galaxy S6
  • Galaxy S5
  • Galaxy S4
  • Galaxy S3
  • Galaxy Note 5
  • Galaxy Note 4
  • Galaxy Note 3
  • Galaxy Note 2

 

What Does Not Registered on Network Error Mean? 

The reason why you see Not Registered on Network error is because your SIM card is unable to connect to your carrier’s network. And when you can’t connect to the network, you won’t be able to make or receive calls and text messages. Aside from Samsung, this is a common issue among Android phones, regardless of who your carrier is or your phone’s make and model.

What causes Not Registered on Network error?

Based on the customer’s experience above, their device is unable to detect the network and up comes the “Not Registered on Network” message. There are many ways this can happen, and below are the reasons why: 

  1. The IMEI number was changed. This usually occurs after getting an update and the device IMEI number (serial number) is changed to “SN 0000″ and it shows that your device SN number has been broken and need to be fixed.

  2. You’re APN or network settings are not properly set up. 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.

  3. Your device has been blacklisted. 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.

If the problem was the APN or network settings, 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.

For everybody else here are the four ways to fix this problem and finally have use of your cellphone.
