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

Every week, no, make that every day, at UnlockBase, 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:

“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!”

The ‘not registered on network’ error

The ‘not registered on network’ error

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
  • Galaxy

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.

    I applied the ariza patch. But it still says that my phone is not registered to the network. How can I fix this ? Ihave a rooted galaxy note 2 gt-n7100 .

    • When you type *#06# your IMEI seems correct ? Did you try the other method ?

  • Sillo Syben

    Do you guys answer your support line, voice mail or emails? Galaxy S6, SM-G920T on AT&T, was unlocked with your tool for about two months, now getting “Invalid SIM Card” “Network locked SIM card inserted” error. These troubleshooting steps either don’t apply to my phone or don’t work. Been without my phone for 3 days. Do you have any sense of urgency?

    • We provide 24/7 support by email where we answer of 500+ email / days from Monday to Friday in less than 12 Hours and from Saturday to Sunday in less than 24 Hours. Our email is [email protected]

      • Sillo Syben

        Then why have you not responded to my issue yet? My unlock code was working for two months and now is not. None of the troubleshooting steps on your web site have helped. What additional information do you need from me and who on your side is looking into this?

        • I don’t even know what’s your email, I just did a search on my mailbox with keyword “syben” and find nothing. We do also check our Spam Folder every week so we clearly don’t receive any email from you. But I can assure you we answer any single email we receive… You are one of the 600 email we receive daily, and we take care of every single request we receive. So please forward all details by email to [email protected] (IMEI, License ID, etc….) so we can move forward.

  • Paul Alexandru Cazacliu

    In my case, changing in the mobile networks from WCDMA/GSM (auto connect), to WCDMA only, has solved this issue. Thanks, so Dear Unlockbase team.

  • Roland Sz

    Guys i have a same problem and when i wanna select virgin is just say unable to select this network

  • DonM

    Thank you for the time and effort in making this. It helped fix my problem. Ultimately I ended up removing the battery and SIM card while the phone was on (I have a Samsung) and cleaning the contacts of the SIM and battery with a soft pencil eraser. When I put everything back together it worked! What a relief!
