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

Posted


At Swiftunlock, 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:A


“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!”


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.

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