Of course, anyone who encounters a block on their phone for the first time will certainly want to know who is blocking their phone and why, and most importantly, what to do about it and how to get the device back to work. Our article will talk about this.

The first thing to start with is what is " unlock" or " unlock"Unlocking means the process of unlocking a device operating in the network of a certain operator or only in a certain region, so that the device begins to work in the networks of any other operators in the World.

Almost all popular brands of smartphones are subject to blocking: iPhone, Samsung, LG, ZTE, Huawei, Alcatel, Motorola, HTC, BlackBarry, Nokia, Sony, Lenovo and many others.

The blocking of the device is installed directly by the manufacturer in agreement with the operator. The operator buys a batch of devices for their subsequent sale with a contract or other special offers. Depending on the country and the specifics of the legislation, operators undertake to provide unlocking for those devices that have been fully paid by customers and for which there are no debts to this operator. But even in this case, the unlocking is not done “automatically”. It is assumed that a client wishing to unlock a device must contact his operator with a request for unlocking and if all the requirements and conditions of the operator are met, the request will be approved.

But in reality, quite often we are faced with a situation where the client was not aware that the device was blocked. It is not uncommon for “victims” of various auctions to contact us, who have become owners of phones with a request to enter a code and they do not even know approximately who the operator is and where to get the code. In all these cases, our service can help you get necessary information and unlock the device.

Now let's move on to the most popular questions from owners of locked devices.

1. Is the unlocking done remotely, or do you need to send your phone to someone?

In 98% of cases, unlocking for all brands is carried out remotely. For unlocking iPhone, if the service thatDo you need in this moment available,it is enough to know IMEI (You can view IMEI by typing the combination *#06# ) Choose a service on the list , place an order and wait for the specified time. After the period specified in the description of a specific service has expired, you receive a notification that the phone is “unlocked”. You don't need to enter any codes. Simply turn on the phone, insert any SIM card and enjoy the full functionality of the device.

For other brands you will need to enter an unlock code(Samsung, LG, ZTE, Huawei, Alcatel, Motorola, HTC, BlackBarry, Nokia, Sony, Lenovo),which can be ordered in this section. After entering the code that we provide, you will see the message " unlock succesufull", after which the device will begin to accept other SIM cards.

In 2% of cases, unlocking foris possible only with the help of special professional equipment. This method is used by workshops and service centers for devices for which entering the factory code did not work. The most common reason why the code might not work is a change in the factory firmware version. Often to unlock with boxes such asZ3X Box,Smart-Clip2, Sigma, Octopus, Infinity Box, ATF Box, MT Box, SeTool or DC unlocker, The technicians pre-update the firmware and unlock the device using the equipment. We mention this method, since for some devices this method is the only one.

2. How difficult is it? Will there be special unlocking instructions needed?

The number of codes you receive will vary for different brands. If necessary, we will provide you with instructions and video instructions that will help you perform the unlock independently and without errors. For most devices, the prompt for input appears immediately after installationSIM cards another operator. You must enter the numbers of the code you received from us. The procedure for entering the code is simple and even a child can do it. If there are several codes, then they must be entered one by one until one of them unlocks.

For some brands ( LG, Samsung, Alcatel, Sony), the codes will be signed - the code will be preceded by a combination of letters of the name of this code, for example:

For LG: nsck 7897763084466988 nck 3496229542329057 spck 9873062026239162 cpck 8169703907966748 simck 1650700

For Samsung:NETWORK=13082493 PROVIDER=94448471 SUBPROVIDER=17849373 DEFREEZE=31709637 EXTRA=00000000

For Alcatel: NCK: 39781674-30 NSCK: 25659724-12 SPCK: 12578039-80 CPCK/SIM: 26233258-74 CCK: 31735499-64 PCK: 39845806-62

For Sony: SPCK 3919008101778412 NCK 7525182958172609 NSCK 4944786986880749 CCK 6413809135118675

Letters do not need to be entered in the code field. Only numbers from the result obtained. For brands such as ZTE, HTC, Motorola, BlackBarry, Nokia, Lenovo, usually you receive 1 or 2 codes that are not signed and it does not matter in what order you enter them.

3. How can I find out in advance whether my phone can be unlocked?

In order to find out in advance whether an unlock is available for your iPhone, just order a GSX IMEI report check. This check will show the blocking status (locked or not) and show which operator or region the blocking is on. The check will also show whether the phone was locked or was sold already unlocked.

You can also check the operator and blocking status for other brands, such as HTC, LG, Nokia, Samsung, Sony:

All these checks will help you find out remotely, using IMEI only, whether you need an unlock for of this device. In all other cases, for models Motorola, BlackBarry,ZTELenovo, Alcatel, You will not be able to verify whether unlocking is possible until you insert it into the device. SIM cardsu.

If after installation SIM cards You saw a request to enter a code, which means you can place an order to receive an NCK code. If the phone does not request a code, then unlocking it is not possible, or it can be done with special equipment in the service center.

It is worth noting that there are a number of operators that block devices without providing the possibility of unlocking: VerizonSprintTracfone,Net10,Straight Talk

These are all American operators, and it is better not to buy phones with such a lock. Dedicated to this issue.

4. Is the unlocking temporary or permanent? What does this depend on?

Unlock for brands Samsung, LG, ZTE, Huawei, Alcatel, Motorola, HTC, BlackBarry, Nokia, Sony, Lenovo, etc., which was carried out using the code entry method, is permanent. If the unlock was successful and the code was accepted, then no matter what manipulations, firmware or updates you perform with the device, the phone will not be blocked again.

In case of iPhone, the unlock can be permanent (official) or temporary (WorldWide service). It all depends on whether official unlocking services are available from a particular operator or not. If the unlock you plan to order is not permanent, this will be stated in the service description.

There are also rare operators and unpopular services for which unlocking may be temporarily unavailable. If the service is disabled, you can subscribe and wait for the service to resume. As for disabled services, there is no preliminary deadline on when they will resume operation. If it turns out that youriPhoneblocked by a rare operator for which there are no active unlocking services, you can contact the sellers of R-SIM adapters, perhaps they will help you get a temporary unlock using a chip.

5. In what cases does the unlock fail?

Concept " Unlock is gone " (re-locking a device that was previously unlocked) applies exclusively to the brand iPhone, to phones that were unlocked using an unofficial method. This kind of unlock is used for those devices that, for a number of reasons, cannot be officially unlocked (for example, the device was lost and is blacklisted by the operator). That is, the operator will not approve the unlocking of such a phone.

There is also a risk of re-blocking for devices that have been removed from the blacklist and subsequently officially unlocked. For anyone who has carried out such manipulations with the device, it is recommended to follow several rules to avoid repeated blocking:

Do not restore via iTunes;

Avoid complete loss of charge and overload of the phone;

Do not remove the battery if it is removable;

Do not reinstall the SIM card.

6. Is it possible to unlock devices that are on the operator’s blacklist?

This unlock is only possible for some operators. In our price list, the service names usually indicate whether unlocking of blacklisted devices is supported. To check if your device is blacklisted, you can order a special check - Check iPhone Blacklist Worldwide . This check may showBLACKLIST status - if the device was lost or stolen and blacklisted by the operator.

To clarify the possibility of unlocking your iPhone, consult us via support@site

7. How does unlocking affect the phone's performance? Will there be any restrictions?

Unlocking, regardless of the brand, does not affect the operation of the device in any way and does not limit its functionality. After unlocking, the device must operate in the frequency range declared by the manufacturer, according to its specifications. An unlocked device will function exactly the same as a device that was originally sold without being locked. You will not see any difference in its work.

As you can see, today there are many various methods unlocking that allows you to bypass restrictions from mobile operators. Often these are official unlocking methods through the operator or using the factory code. In rare cases, special boxes and equipment are needed so that you can freely use your smartphone.

SIM card lock or Network lock is a restriction built into GSM and CDMA smartphones either by service providers or smartphone manufacturers to restrict the use of the device in certain regions or restrict access to other network services. Phones can be programmed to only receive certain ones.
Mobile country code (will only work in one/predefined country).
An identification number mobile subscriber(MSIN only accepts certain SIM cards)
Code mobile network(accepts network provider only).

The main reason why network providers block SIM cards is because the service providers offer phones at discounted prices and sell their service limited so that customers only use their specific network so that the service providers can not only get the discounts they were offering , but also new profits from user access to their services. This method can increase the number of customers for both smartphone manufacturers and service providers. Thus, they come together to implement a business model.

In this material we have collected the most important information about what SIM-Lock is on a phone, where it comes from and how to disable it. We will also talk about whether it is possible to determine whether it is blocked by the operator or not before purchasing.

What is operator SIM-Lock?

SIM-Lock is a generally accepted designation for SIM card locking, which is used by the GSM operator cellular communications. Simply put, if your phone, when installing a SIM card, starts asking for a network unlock code for the SIM card* or displays a text stating that “SIM card is invalid,” then we are dealing with blocking from the operator.

*Do not confuse with the SIM card PIN, which is set by the user.

Who locks phones and why?

Your phone is blocked by your mobile operator to ensure that you only use its services and pay your mobile bills monthly.

There is also quite a large demand for locked phones, since a phone with a lock costs significantly less than an identical device without a lock. But the whole secret is that with the phone you take on a contract - that is, you undertake to pay for the services of this operator certain time. Thus, what you “saved” on the phone itself is secretly included by the operator in the cost of its services, which you agreed to pay.

But what if you suddenly change your mind and want to change your communication provider before the contract is closed? It is to avoid such situations that the operator introduces “sanctions”; in essence, it insures itself against unscrupulous clients and automatically blocks the operation of the device if a “foreign” SIM card is installed in it.

Unpleasant “surprises” with a locked phone most often await buyers on various online platforms, when buying second-hand or on other popular internet auctions.

How to unlock your phone and remove operator lock?

In the vocabulary of masters and service centers, removing the lock from the operator is usually called “unlocking”. This is the process of so-called “decoupling” of a device from its “native” network.

It is worth noting that the phone cannot always be unlocked and there are models that cannot be unlocked. Also, unlocking can be permanent (forever) or temporary (if you update the device to latest version- may be blocked again).

But let's start with what we have different ways and unlocking methods:

unlocking using the operator who blocked your phone,
unlocking using special equipment (boxes and dongles for unlocking in a service center or from an experienced private technician),
unlocking using Smart chips (R-sim, Gevey...),
unlocking using special programs (DC-unlocker, Sam-KEY...),
unlocking using specialized sites that work remotely using IMEI (https://imei-server.ru/).

Let's take a closer look at each of these options and evaluate its disadvantages and advantages.

Unlocking your phone using an operator

In this case, we are talking about the fact that if you are the buyer of the device or you have personal data of the person for whom the purchase contract was issued, then you have the right to contact the operator’s technical support directly (for example, through the official website of this operator) and demand that your device be unlocked. The operator will accept your application and check your accounts in the database. If you have no debts, the term of your phone contract has expired, if this phone is not blacklisted as lost or stolen, then you will be provided with FREE unlocking within a period of a couple of hours to several days.

- absolutely free,

— unlocking carried out by the operator himself will NEVER fail.

— you need to have information about the owner who made this purchase (including the number bank card and other personal information)

— you need to contact the operator yourself and communicate with their support. If the phone was brought from a country whose language you do not know, difficulties may arise.

Unlocking your phone using special equipment

This type of unlocking is carried out exclusively by service center masters and private craftsmen. They buy special equipment that allows them to unlock phones in bulk and at minimal cost. We are talking about boxes: Z3X, ATF, Infinity Box, Octopus, Furious, Sigma, DC-unlocker, etc.

To unlock one phone, it makes no sense to buy this equipment, since you need to be able to use it and the cost will be commensurate with the price of the phone itself.

— you can unlock phones for which the operator refused to provide unlocking for a number of reasons (not a closed contract, debts, phone on the black list),

— the unlocking will not fail.

- paid service,

— you need to look for a service that has equipment that can unlock your particular model.

- not relevant for iPhones.

Unlocking using Smart chips (R-sim, Gevey...)

This unlocking method is only applicable for Apple devices, if you have a different smartphone, this information is not relevant for you.

Unlocking an iPhone with a Smart chip means purchasing a special “spacer” chip, which is installed in the SIM card tray along with the SIM card in order to “deceive” the phone into accepting it as its own. This cunning way to bypass the blocking was invented by craftsmen from China, who spent a long time racking their brains over how not to pay “Uncle Sam” extra money.

- one of the cheapest unlocking methods.

- this is a temporary unlock, the chip can stop working at any time. Apple is trying to combat this in an illegal way bypass the blocking. There is a known case when, 6 months after the launch of the R-sim chip, Apple company changed the algorithm for registering a device on the network, as a result of which all R-sim smart chips “died” in an instant all over the World! The owners of such phones had no choice but to look for other unlocking methods, or wait until the Chinese come up with and release a new chip for sale with a new algorithm.

- you need to properly configure your phone to work with this chip,

— glitches and temporary loss of the network during operation are possible.

This unlocking method does not work for iPhones; it is only available to owners of phones from other brands.

Through DC-unlocker you can unlock the following models: Huawei, ZTE, Longcheer, Lonsai, MOMO, Maxon, MegaFon, Merlin, Micromax, NETGEAR, Nokia, Novatel, ONDA, Optimus, Option, Orange, Ovation, Pantech, Sierra, SkypePhone, TMN, Toshiba, Vodafone, iNQ.

Via Sam-KEY - Samsung models.

The essence of the method is this: you need to download it to your computer special program from the official websites of these products, then install it on your computer. Then connect the phone to the computer with a cable, the program will immediately detect it and offer to unlock it. All you need to do is click on the “next” and “ok” buttons several times. In total, the procedure takes 5 minutes and is accessible to any user who does not have any special knowledge.

Both sites (DC-unlocker- www.dc-unlocker.com and Sam-KEY- http://www.samkey.org/) have been working for a long time and successfully, in addition to software unlocking, they provide the SC with unlocking equipment, so they can safely trust.

- one of the cheapest unlocking methods,

- no special knowledge is required to unlock your phone using this method,

— such unlocking is permanent and “lifelong.”

— you need to obtain a login and password to enter the program. You can get, or rather buy, this login and password not on the developers’ website, but only from its official resellers. For example, the official reseller of DC-unlocker is the previously mentioned resource https://imei-server.ru/.

In this case, we are talking about ordering an unlocking service on a specialized website that works remotely and provides a wide range of services, including the sale of equipment for the service center, activation and extension of support for boxes and dongles, which we mentioned earlier. This is the so-called indirect unlocking method, when you contact an intermediary to quickly and efficiently receive a service.

In fact, there are a lot of unblocking offers on the Internet, both from individuals and from similar sites, so the risk of falling for scammers is quite high. In this regard, we will not list all the sites known to us, but will focus on the one that does not cause us any doubts and has positively proven itself, working in this area for many years.

In this case, we were interested in the section of the site that contains video instructions for unlocking - these are short videos that show the entire process of unlocking a phone in order to understand what it is and what it really looks like.

This site can be used not only to order any unlocking services, but also for regular consultations. For example, you want to buy a phone of a certain model from a certain operator, or make sure that such a phone can be unlocked. To get information, just contact the site’s help chat with a question that interests you.

— specialized unlocking sites provide services remotely using IMEI (You can view the IMEI of any phone by dialing *#06#). You can unlock your phone online - without leaving your home.

— any brands are supported. Find out the cost of unlocking specific model You can use a consultant in the chat, or look at the price list on the site.

— unlocking for most brands is “lifetime” (with rare exceptions)

— the ability to unlock those devices that can no longer be unlocked. For example, Sony phones that have exhausted attempts to enter the code, or Samsung phones with the same problem.

- the ability to order a special check that will show complete information about the phone - whether it is blocked by the operator or not, whether iCloud is enabled (on iPhone) or Mi Account Lock (on Xiaomi). You can find out the warranty status and also check if the phone is blacklisted.

— getting unlocked is easy: place an order, pay and wait for the result. In case of any problems, the order can be canceled and the payment refunded.

— a wide range of prices, many expensive services.

In general, as you can see, today there are many options that allow you to disable blocking from operators. Each method has its own advantages and disadvantages that are worth considering.

Finally, we note that neither the activities of large companies blocking devices, nor the activities of their opponents who are engaged in removing blocking, are in any way regulated at the legislative level in the CIS countries. That is, there are no laws that would prohibit operators from blocking devices, or, on the contrary, that would prohibit removing this blocking.

Thus, all activities of both parties continue to remain a “gray zone”, where those who adapt faster and better to rapidly changing conditions succeed.

We hope this review will be useful to you and help you avoid unpleasant situations with the purchase of locked devices. For those who are interested in this topic, we attach a video of the unlocking process Sony phone Xperia L1 G3311, which has exhausted attempts to enter the code because the wrong code was entered many times. Unlocking was carried out remotely using the S1 network unlock tool.

Reading this article lets you know the three best ways to sim unlock your Android without code. You can adopt any one of the mentioned methods to remove the restriction imposed on your phone. The steps as you read are simple and easy to follow. The most important fact about these methods is that you don’t needany unlocking code.

When purchasing a smartphone second hand, buyers pay great attention to checking it appearance and basic functions, however, they completely overlook one important point: they do not check with the seller whether the gadget is locked. A locked smartphone will cost the buyer less, but then you will have to pay a hundredfold for the immediate benefit. What is a locked device and why is it not recommended to buy such a device?

Locked iPhone ( Sim-Lock) is a gadget that can work with SIM cards of only one mobile operator. Such smartphones are sold together with mobile communications contracts (usually two years). By purchasing a Sim-Lock device, the user voluntarily deprives himself of the right to choose: if the conditions offered by the communication provider no longer suit the iPhone owner, he will not be able to go to competitors.

A SIM card from the “right” operator is required to activate the locked device. This means that a gadget with Sim-Lock cannot be used even as a multimedia device - for watching movies or listening to music.

The practice of selling locked iPhones is common in the USA, Australia and Western European countries. In Russia, you won’t find iPhone Sim-Lock in the windows of large electronics stores and cellular communication stores, but when purchasing via the Internet, you can easily come across such an example. Most likely, the device will be locked to SIM cards from a non-domestic provider mobile communications, but foreign (like AT&T), so you won’t be able to solve the problem by simply switching to another operator.

How to find out if an iPhone is locked or not?

Rather than solving a problem, it is better to prevent its occurrence. In order not to get into a stupid situation, finding yourself with an expensive device, but absolutely unsuitable in Russian realities, you should check your iPhone for the presence of Sim-Lock before transferring money to the seller.

There are several ways to understand that an iPhone is locked:

Insert your SIM card. Device without Sim-Lock quickly recognizes the operator. If the gadget is locked, you will see the message “ Activation Required» (« Activation required»).

Through Internet services. Thematic sites claim that free services There is no information left to check Sim-Lock iPhone by IMEI, thereby misleading readers. At the time of this writing, the website www.iphoneox.com exists and works perfectly, where they won’t ask for a single ruble for such a check.

Before using the site, please find out Device IMEI– this number can be found on the iPhone box or in the smartphone settings (path “ Settings» — « Basic» — « About this device»).

A table will appear with detailed information about the smartphone. Find the item " Sim-Lock Status"- if opposite it is “ Unlocked", which means the gadget will be able to work with SIM cards of all operators.

There are other similar portals (for example, the more famous www.imei.info service), but you have to pay to use them. The cost of the test will be about $3.

By model. This is not about modification ( 5S, 6, 6S), namely about models. You can find out the model in the section “ About this device» in the device settings.

The two letters after the numbers in the model designation indicate the country for which the device is intended. In our example, these are the letters “ RU“We understand that this iPhone is for Russia, which means Sim-Lock it cannot be on it.

If you buy second hand and see that in the model designation instead of “ RU" is worth, say, " LL"(gadgets for Americans), you will need additional verification, because in the USA iPhones are sold both with and without a SIM lock. Pay attention to the digital code in the designation: numbers 608 , 610 , 318 , 319 they say that the device is blocked.

How to unlock an iPhone?

There are two ways to unlock an iPhone, and each of them requires material costs on the part of the owner of the gadget.

Hardware unlock

Hardware unlock involves the use of a special adapter called Turbo Sim, which is placed in the SIM card tray along with the card itself. The chip of such a device contains unique IMSI identifiers of several well-known mobile operators– this allows you to get rid of the blocking.

When activation occurs, on an iPhone with Turbo Sim a special code arrives that unlocks the radio module and modem of the device.

Hardware unlock has a number of disadvantages:

The connection is getting worse.
After each signal loss, you have to carry out the activation procedure again.
Functions iMessage And Face Time difficult to set up.
Many Turbo Sim(for example, companies R-sim) do not allow you to perform any actions with the gadget’s firmware - in particular, update the OS.

Common in Russia Turbo Sim manufacturers such as Gevey, R-Sim, Heicard. Adapters from each company have their pros and cons. Let's say Turbo Sim from Gevey are very fragile, but they allow users to update their iPhone. R-sim, on the contrary, are durable, but for each upgrade the owner of the gadget will have to buy a new adapter from this manufacturer. Heicard stand out from others in that they provide high quality communications.

The cost of one adapter ranges from 1300 to 2000 rubles.

Official "unlock"

What to do if you don’t want to endure the inconvenience associated with using Turbo Sim? Then you need to create an official request to the operator, notifying him of your desire to remove the blocking. The operator can meet halfway, but you will have to pay him the nth amount - we can say that the owner of an iPhone purchases from a specific provider the right to choose a cellular service provider.

The cheapest way to unlock an iPhone locked to an American operator AT&T– it will cost about 1 thousand rubles. Request to cancel blocking AT&T should be submitted here - www.att.com/esupport/index.jsp. The cost of “unlock” reaches 15 thousand rubles (upon withdrawal Sim-Lock, say, a Finnish operator DNA).

You can contact not only operators directly, but also third-party providers who are able to organize an official “unlock” faster (the operator will have to wait about a month for a response to a direct request). It is important to approach the choice of contractor responsibly: you should contact companies that have real offices, and avoid companies that require payment by electronic money and promise instant unlocking.

Conclusion

Before you make a conscious purchase of a locked smartphone, consider whether this deal will be profitable in the long run. To do this you need to consider the cost of the adapter Turbo Sim or specialist services unlocking iPhone(depending on the preferred type of unlock). It should also be taken into account that the buyer will not be able to use the iPhone straightaway– he will have to wait until the removal work is completed Sim-Lock or delivery the required adapter. This inconvenience gives the buyer the right to demand an additional discount.
