When you insert a SIM card from a different cellphone operator than the original, your Samsung phone asks for an unlock code and prompts you to enter the “Network blocking control key” or “SIM Network Unlock PIN“. So at this point you decide to go online and receive a cellphone unlock code.
If upon entering your unlock code you receive a message such as:
– “Failed to unlock network”,
– or “Failed to request“,
– or “Your attempt failed“,
– or “Unlock Code Request Unsuccessful“
There are three possible scenarios:
Scenario #1 (in 90% of cases):
You (or the previous owner) entered too many wrong codes, it’s what we call in our industry “Phone Freeze”. (if so, see the solutions below).
Scenario #2 (In 9% of cases):
Non-original ROM. You (or the previous owner) may have installed or flashed your Samsung with a Custom ROM that is not genuine (like Avatar, or Cyanogen MOD to name two), therefore the code provided will not work (if so, see the solutions below).
Scenario #3 (In 1% of cases):
The code is actually wrong. Yes, we do not claim to be perfect, sometimes the computerized processing of orders produces the wrong code or, very rarely, even Samsung or the cellphone operator has supplied a false code base.
Scenario #4 (New since Summer 2015):
Well the last scenario is even worse than the previous one. Since summer 2015 two networks (MetroPCS and T-Mobile in USA) started to release Samsung cell phone coming with an app install by default called “Device Unlock App”. Those are simply not asking for code, and even if you use some secret code to make those ask for a code, they will simply not work. Do not order code if your phone is one of those since the code you will receive will be simply useless.
How to use the code if your Samsung Cell Phone is “FREEZE”
The message “Network unlock failure” or “Phone Freeze” means that someone has already tried to unlock the phone with a bad code, and the number of attempts has exceeded the allocated number of times permitted, (it’s usually a maximum of 3 trials tries for a wrong code). In this case it is very likely that if you bought a used phone, the previous owner attempted to unlock it out with a bad code by visiting an untrustworthy free unlock website.
At UnlockBase, our codes are 100% correct since they come directly from the Samsung factory.
If you choose a manufacturer code, you receive two codes:
Code 1 => NETWORK unlock code or code (called NCK Code).
Code 2 => UNFREEZE (or Defreeze) Key to unlock the test counter (called MCK Key).
The purpose is to “unfreeze” the phone with the code and thereby unlock the phone from the NETWORK.
Methods for removing Samsung Freeze with MCK code
Depending on your model, several methods exist to unfreeze with the MCK code your Samsung:
Unfreeze Solution #1:
Turn off your phone, take out the SIM card and then replace it with a non-compatible SIM card
(if the phone application demands it, type the PIN number of the SIM card).
When the message “Phone Freeze” appears, call for the unfreeze code and confirm with the button “call” or “#” or “OK” (Note: be careful when entering this code, nothing will appear on your mobile screen, this is normal, you must enter this code blind.)
Unfreeze Solution #2:
Again, insert a non-compatible SIM card into your phone (if the phone application demands it type the PIN number of the SIM card). When the message “Phone Freeze” appears, enter the code: #7465625*638*UNFREEZECODE# (and replace UNFREEZECODE by the MCK Code we provide.)
Unfreeze Solution #3:
Insert a non-compatible SIM card into your phone,
(If the phone application demands it, type the PIN number of the SIM card)
Enter the unlock code 1 (NCK / Network): then press OK. Answer the phone “unlocking the failed network”,
Next enter the second code (MCK/Unfreeze), then press OK. Answer the phone “unlocking the failed network”,
Re-enter the unlock code and the phone will be unlocked,
Turn off and restart your Samsung mobile phone.
Unfreeze Solution #4:
Insert a non-compatible SIM card into your phone,
(If the phone application demands it, type the PIN number of the SIM card)
Emergency call only: Press CALL button and enter the unfreeze (MCK Code) directly,
The phone will ask you the code for the network, enter the NETWORK code that was supplied.
Unfreeze Solution #5:
Insert a non-compatible SIM card into your phone, and turn on the phone,
(If the phone application demands it, type the PIN number of the SIM card)
The phone is blocked, Click Call and enter the following code *7465625*638*CODE#
(where CODE is the unlock code of the operator)
The phone does not accept the code and returns the error:
‘Phone Freeze. SIM not available. Please contact your operator‘
Turn off your phone and remove the phone battery
Replace the battery and turn the phone back on
The phone is now unlocked and everything works
Note that there is no trial “tries” limit to enter the unfreeze code, so do not hesitate to keep trying to enter the correct code and then get the ‘unfreeze’ sign with the display inviting you to enter the NETWORK code.
To received the UNFREEZE CODE, make sure you order “FACTORY CODE”
If you choose the operator solution, which is the cheapest solution, you will receive only the unlock code (NCK Code). For the network code + unfreeze code, choose the option ‘factory code’. It’s usually more expensive but it’s also much more reliable and faster.
The Ultimate Solution: Unlocking software + USB cable
As stated earlier, if you flashed your Samsung with a non-original ROM, it is almost certain that the code will not be accepted. In this case you will need to find the original firmware and use Odin to re-flash the firmware with an original Android version, and if possible one that corresponds to the distribution of the original operator. If in spite of all this, your phone does not accept the unlock code, we can provide you with software to unlock your Samsung, provided that the model is compatible (90% of the models to date are supported).
All UnlockBase customers are offered this method after having tried everything else and still fail to enter the provided code. This requires a Windows PC, USB cable and some studying of our tutorial but at UnlockBase we never give up so easily!

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
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:
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.
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.
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.

We can source the Unlock Code for any Samsung from Argentina. However if you have a Samsung Galaxy Core from this country, you will need to Flash / Upgrade the firmware of the phone to be able to enter the Unlock Code in your Cell Phone. Why ?

Update 19th June 2015: Too complicated ?! Don’t want to risk to flash your phone with new firmware ?! Please take a look to our new Official mobile “Device Unlock” app method to unlock your Samsung using official Android App.
The Samsung Galaxy Avant (SM-G386T) cell phone from T-Mobile USA is using a custom firmware preventing the phone from being unlocked by code as there is no way to enter it (the phone is simply not asking for “SIM Network Unlock PIN”). Before this post, the only way to Unlock the phone was by using the official T-Mobile “Mobile Device Unlock App” which is an Android app called “Device Unlock” that allows you to request and apply a mobile device unlock directly from the device.
So what do you do if you get an Unlock Code but you cannot use it?
Now there is a solution consisting of an upgrade to the firmware of the phone with MetroPCS Firmware instead of T-Mobile, and this will allow the phone to ask for the Unlock Code. Below you will find a tutorial about how to do this. Once you flash (update) your Phone with this New Firmware, please make sure that your Samsung SM-G386T is asking for “SIM Network Unlock PIN”. And if the answer is yes you can then click this link to order the Unlock Code of your Samsung Galaxy Avant from T-Mobile USA.
