How to unlock an MTS phone if you forgot your password

Recently, many operators provide their customers with the opportunity to buy a good phone at a good price, but at the same time blocking the ability to install a SIM card from another operator. Of course, this drawback is written in small print and not all buyers know this “zest”, although the instructions always say so.

But what if you inserted a SIM card into your phone and received a notification asking you to enter a special unlock code for this SIM card? What to do in such a situation? Is it possible to remove the lock yourself so that you can continue to use your phone as before? These questions are of interest to many users, so we will try to give the most detailed answer to each of the above questions.

MTS phone is blocked - what to do

In solving the problem of unlocking an MTS phone, it is necessary to start from the reason for the appearance of the block. If it is associated with the smartphone itself, which stopped working due to an incorrectly entered software password, this can only be eliminated with the help of flashing and other special methods that are offered by modern service centers. If the block occurred as a result of incorrectly entering the PIN or PUK code, you will need to replace the SIM card with a new one at the sales office.

There is also a third type of blocking - linking a smartphone to one operator. It is also possible to remove it if you have certain skills, but it is much more difficult to do.

How to find out the network unlock code

This is paid, you can get it from your operator, or rather buy it. Don't think it's cheap, not at all. In some cases, you can unlock the device yourself using various utilities, but this is illegal, of course. The same applies to 3G/4G modems that have operator lock. If you saw on the Internet a “sweet” offer to unlock your smartphone, then it is better not to believe such an offer. A reasonable solution would be to unlock it on site, in some workshop, if the operator is expensive. And by entering the left codes it is possible to get a brick (operators also install protection).

How to unlock an MTS phone if you forgot your password

In this case, it all depends on which digital code was forgotten or lost. When selling a SIM card, two main passwords are attached: PIN and PUK. If you enter the PIN password incorrectly three times in a row, the phone will be locked and then the phone will start asking for PUK. The latter can be entered ten times, after which the SIM card will be completely blocked. To avoid this, you must always keep the card sales agreement at hand or remember the numerical combination by heart.

Even if the PIN and PUK were entered incorrectly and the card was completely blocked, it is possible to restore it with the same number, balance, tariff plan and set of options. To do this, you will need to contact the MTS sales office with your passport and old card and explain the current situation. The replacement will be made on the same day.

Delivery of a new set

When a gadget is stolen or lost, the SIM card becomes inactive. This is a serious problem that requires an immediate solution. It is not always possible to contact company employees. MTS decided to expand the list of services by introducing a useful “delivery” option. Now clients receive a new copy with the same number without visiting the company.

The official website of the operator invites subscribers to fill out an application. A special form will open that must be filled out. The questionnaire requires indicating the city and type of delivery. On the page, the user enters the number of the SIM card that requires restoration. Fills in other required fields. Next, the online system will offer help and tips to complete the procedure. After confirming the request, the client can only wait to receive a new card that will replace the blocked one.

How to unlock an MTS phone if you forgot your graphic password

It is possible to unlock your MTS phone using a hard reboot. In this case, not only the graphic key will be canceled, but also all information from the MTS phone, which you also need to prepare for.

The procedure is carried out in several steps:

Turn off power.
Press the power button and volume up button at the same time.
Using the same volume key, select “Wipe data/factory reset” in the menu that opens.
In the next window, select “Yes - delete all user data”.
In the newly opened menu, select “Reboot system”.
Leave the smartphone until it is completely restarted.

It is also possible to unlock an Android smartphone using a call. To do this, you need to call this phone from another and accept the call. During a conversation, you will need to further go to the settings and the “Device lock” menu item to deactivate the pattern.

Model Surf 4G

Free unbinding of MTS Smart Surf can be done in the same way as described above. Through the Engineering menu. If the performed procedure turns out to be useless, there is a second method:

Unlocking MTS Smart Surf 4G begins with obtaining Root rights (using the KingRoot application).
Follow the link to download the archive. Install RootExplorer.

https://gsm-obzor.ru/wp-content/uploads/2016/01/MTS-Smart-Surf-4G-Unlock-Gsm-obzor_ru.zip

Next, you need to unpack the archive and copy the file from it to the phone’s flash drive.
Free decoupling of MTS Smart Surf 4G from the operator continues by opening the file copied from the archive in RootExplorer and calling it with a long tap on the pop-up menu icon. We copy. We follow the path ROOT/protect_f/md/. Copy the file here with replacement.
Click on the inserted file and hold down until a menu appears. In it, select the Permissions item. Set the license to 0777 (all checkboxes). We complete the action by clicking OK.

Reboot the device. Ready. If done correctly, the phone will be unlocked.

In order to unlock the MTS Smart Surf 4G dual sim lock black smartphone, you need to find out the IMEI of both slots (enter *#06# in the dialing window). You must enter the combination by inserting a SIM card from another operator into each slot. Then use unlocking services by providing IMEI.

How to unlock a phone from MTS for other operators

This type of blocking can be removed by contacting a service center or by yourself. To do this, it is recommended to use the following instructions:

Insert a SIM card from any telecom operator into your phone.
Turn on the device and wait for a window to appear in the form of which you will need to enter the NCK code and click “back”. In the input line, type the command *#*#3646633#*#*.
After that, once in the engineering menu, find the “Simme Lock” tab and select “Network Personalization” from the menu that opens.
In the “Unlock” button, type “12345678” and click “Finish”.
Select the item “unlock pemanently”.

Now the smartphone will be able to work with any telecom operator. This mechanism works both on MTS phones and smartphones from other companies.

Unlock Huawei from pattern or number code

Have you forgotten the graphic or numeric code? We have prepared instructions for you on how to remove it! Attention, all data from the phone will disappear!

In this article we will try to lift the veil of secrecy over the Huawei and Alcatel unlocking algorithms. Everyone knows that devices from these manufacturers are unlocked with a code, but how is it calculated and where does the unlock code come from?

In our article about we wrote that the unlock code

may be a function of the phone's IMEI (and thus can be calculated) or it may be hardcoded into the phone's flash chip (and then it will only be recognized through the manufacturer's internal database). Let's look at Huawei modem models with the old algorithm, which we wrote about earlier -. As we said, the unlock code for them can be calculated with a special calculator, but how does this calculator work inside?

Naturally, the manufacturer carefully hides the algorithm for generating unlock codes (in the case of Huawei modems with the old algorithm, Old Algo, the unlock code is a function of IMEI, i.e. NCK = f(IMEI)

), but in this case the algorithm has already leaked into the network and in this article we will look at it. I repeat that everything described applies only to models E150, E1550, E155, E156, E156G, E160, E160G, E161, E166, E169, E169G, E170, E172, E176, E180, E182E, E196, E226, E270, E271, E272 , E510, E612, E618, E620, E630, E630+, E660, E660A, E800, E870, E880, EG162, EG162G, EG602, EG602G, Vodafone K2540, Vodafone K3515, Vodafone K3520, Vodafone K3565 , Vodafone K3715, etc.

NCK code generator algorithm for Huawei

The source code of the algorithm in PHP looks like this:

Huawei Algo PHP Source function CalcOldNCK($imei,$secret = "hwe620datacard") { $magic = substr(md5($secret),8,16); $n = str_split(md5($imei . $magic),2); foreach ($n as &$v) { $v = hexdec($v); } $n1 = $n ^ $n ^ $n ^ $n; $n2 = $n ^ $n ^ $n ^ $n; $n3 = $n ^ $n ^ $n ^ $n; $n4 = $n ^ $n ^ $n ^ $n; $s = sprintf(“%02s”,dechex($n1)) . sprintf("%02s",dechex($n2)) . sprintf("%02s",dechex($n3)) . sprintf("%02s",dechex($n4)); $n = sprintf("%d", (hexdec($s) | 0x2000000) & 0x3FFFFFF); return $n; }

Here, at the input of the CalcOldNck function, $imei is a string from the IMEI of the device, and $secret is a secret constant equal to hwe620datacard.
As we can see, first the MD5 hash from $secret is calculated, which is equal to “a32fe72c 5e8dd316726b0335
d5513ba0″, then the selected 16 characters are taken from it. This will be $magic.
Then we calculate the MD5 hash from the IMEI contact and the resulting $magic constant. Let’s assume that our IMEI is 860650020246212, then combining IMEI and $magic will give us the string “8606500202462125e8dd316726b0335”, and the MD5 hash from it, respectively, “9423f197fafad4887ee169fe0547cf7a”.
Let's split this string into bytes in hexadecimal representation, i.e. 0x94, 0x23, 0xf1, etc.
As a result, we get an array:
Array => 148 => 35 => 241 => 151 => 250 => 250 => 212 => 136 => 126 => 225 => 105 => 254 => 5 => 71 => 207 => 122)
As you can see, the zeroth element of the array is 0x94 (148 in decimal notation), the first is 0x23 (35), etc.
Next, we count the numbers n1, n2, n3, n4 (in fact, these are the bytes of the future NCK) using the formulas:
$n1 = $n ^ $n ^ $n ^ $n; $n2 = $n ^ $n ^ $n ^ $n; $n3 = $n ^ $n ^ $n ^ $n; $n4 = $n ^ $n ^ $n ^ $n;
Where is the “exclusive OR” operation, i.e. XOR.
Thus we get:
N1 = 148 xor 250 xor 126 xor 5 = 21
n2 = 35 xor 250 xor 225 xor 71 =
127
n3 = 241 xor 212 xor 105 xor 207 =
131
n4 = 151 xor 136 xor 254 xor 122 =
155
Or in hexadecimal (n1,n2,n3,n4) = (15.7f,83.9b). We combine these numbers and get a hexadecimal number - 157F839B (360678299).
And we have the last step left, namely, to obtain NCK we perform the following transformation on it - 0x157F839B
or 0x2000000 and 0x3FFFFFF. This can be done using a standard Windows calculator, switching it to programmer view.
As a result of this operation we get 0x37F839B
.
Converting it to the decimal number system, we get the desired NCK (unlock code) - 58688411
.

We check the result obtained with any publicly available Huawei calculator and make sure that we got the correct result:

At the beginning of the article, I said that we will also tell you about the algorithm for generating unlock codes for Alcatel

.
In the archive below you will find Delphi sources for the following Alcatel phone models - V670, C700, C701, PLAYBOY, C707, C717, V770, C820, C825, MANDARINA DUCK, S215, S218, S319, S320, S321, S520, MISS SIXTY, S853. The authorship of the source code belongs to ulymar (atf team member)
. The code is very structured and understanding it will not pose any particular problems even for novice programmers. The compiled application form looks like this:

The article briefly explains what an NCK code is on a phone, and is it possible to get it?

Let's say that you decide to buy a brand new phone from any mobile operator (" MTS

", "
Megafon
", "
Tele2
", "
Beeline
").
They will sell you a phone with a ready-made SIM card from this operator. You have been using this phone for a while and suddenly decided to change the SIM card, and not just to a new number, but to change, for example, “ Beeline
” to “
Megafon
”.

So, you insert a new SIM card into the phone, turn it on and, instead of the expected greeting, you see a similar message on the display: “ Enter the NCK code

" What it is? Why are we required to enter some codes?

What is an NCK code on a phone? How to get an NCK code

Removing the SIM lock

The opportunity to unlock a gadget under the MTS brand to work with MegaFon or Beeline SIM cards is of interest not only to those who buy a phone, but also to other devices for using the Internet - modems and routers. So, on various forums on the Internet you can find questions about unlocking the MTS 823F router model in order to use it with a SIM card from another operator.

Today, four models of branded smartphones are available to purchase from the operator. Their cost does not exceed five and a half thousand rubles, and the most affordable one will cost less than two thousand, and does not have a lock.

Despite this price tag, the phones have quite a wide range of functionality for their category. With them you can use not only the basic functions of cellular communication, but also new solutions. Thus, two of the models currently presented support Wi-Fi calls, which helps to save significantly for those who use their phone to communicate in another region and abroad. That is why unlocking phones from MTS remains a pressing issue for those who want to use them with a SIM card from another operator.

Given the interest in the possibility of converting an MTS phone for use with another SIM card, it is not surprising that there are a lot of proposals on how to do this, and not always for free. So, the simplest option is to get help from specialists in any radio market. For a small fee and within a few minutes, they will help you unlock old models with MTS 970 (970H) and 268 phones, as well as unlock new models of the Smart line if your SIM is blocked.

However, this option is not suitable for those who recently purchased the device. This is due to the fact that in case of flashing, the warranty ceases to apply.

But if you need to unlock a new phone model, you can do it yourself, through the service menu. The task is not difficult, and even an inexperienced user can cope with it.

To get into it you need to type the command ##3646633##, then go to the “network settings” section of the SIMmeLock section, and then to “unlock”. Here you will need to enter a special unlock code. Please note that various sites offer to purchase it online, but do not rush to do so. Enter eight digits from one to eight (or in reverse order) as the code and confirm unlocking.

If the universal method of self-unlocking does not bring the desired result, then you should contact the operator at the salon. Here, after submitting your application, you will be provided with a universal code to unlock your specific device. The service is provided free of charge, but only upon request of the phone buyer, and for this, be sure to take a receipt with you.

other methods

If none of the above options suits you, there are only two options left that will save you from replacing the device.

Transition to MTS;
Help from specialists at the service center.

Go to MTS

Check out the tariff plans that MTS provides to its customers. Look, maybe there is one that will be the same or more profitable for you. If you are ready to switch to MTS, then the issue automatically becomes resolved. Taking into account the fact that the leading cellular operators are now Beeline and MTS, it is likely that at least one of the tariffs will be to your liking.

The MTS company allows its clients to switch to them with the condition of maintaining the number. This will eliminate the need to notify all your contacts about the number change. Although this service is not free, it is an excellent opportunity to unlock your MTS phone in the shortest possible time.

If this method does not suit you for personal reasons, there is another option - contact a service center for help.

Contact service center

This method has one serious drawback - the high cost of payment. Considering that this service does not fall under the guarantee provided to the client when purchasing a device, you should understand that the price for unlocking a smartphone will depend on the price of the phone itself and the prices of a specific service center.

Find out in advance which service centers serve users of your brand's smartphones. If you bought a smartphone from a well-known manufacturer, it is likely that finding a service center will not be difficult. If your device does not have an official representative in your city or even country, it is likely that you will have to pay extra to the technicians for repairing a device that is not included in their price list.

These are all the methods that can be used to solve the problem with a blocked MTS phone. We hope that the tips that were described in this article helped our readers. Remember that MTS is ready to provide comfortable conditions for its customers and the most reliable option for solving the problem will be this option.

Other locks

Often in reviews about branded phones from the MTS operator you can find questions about other types of blocking that their customers have encountered. In fact, such situations have nothing to do with a specific model, and arise due to problems in the operation of the SIM card, or the forgetfulness of the users themselves.

So, you can often come across questions about how to unlock, for example, the MTS 970 phone model using a pattern key. If the user has forgotten the patterns set for blocking, he can remove the blocking using an alternative option. When installing a graphic key, an alternative option is always installed in the form of a digital code or password. If the user has forgotten it too, then the only option is to reset the device to factory settings. In this case, you can save information on it only if data copying via cloud services is set, and for contacts and settings via a Google account.

But if the phone does not see your SIM card, which previously worked properly on an MTS phone, then the problem may be either physical damage to it or to the SIM card tray.

In this situation, just try to reinstall it again, and if that doesn’t help, then to any other phone. If it does not register on another device, you will need to replace it with a new one. This can be done at the company's showroom for free. If the old SIM card works in another phone, then the problem is most likely in your phone, and it will require repair or replacement.
