Turn your attention to second way It is necessary only in those cases: if your tablet freezes, contains a lot of malware and in addition displays a notification about blocking the SIM card slot. Since the second method involves the full firmware of a tablet or phone, without returning to the old version of the system.
Method One: “We will use the Engineering menu”
To call the engineering menu, you need to download the tablet, the PIN code entry form appears again, press the END key, or if it doesn’t appear, just click on the blue phone’s tube, well, where to call and type the following command:

We reveal all the secrets of Android Devices
Phones have long become full participants in our lives. Mankind is so used to gadgets that few can refuse even a day to use the phone. But, like everything in this world, phones are not eternal and various breakdowns often occur. Today we will talk about unlocking the SIM card slot in the phone. If you are a happy owner of a smartphone, we recommend that you visit the official website of the project, which is located at: https://dipol.com.ua/. Here are the most important articles that will help you in some cases, with your own hand, will cope with a broken phone.
The problem of a blocked SIM card slot
Sometimes there are times when phone users decide to change their mobile operator. But, during the attempt itself, the phone gives an error and writes that the SIM card slot is locked. When contacting the support service, you can only hear that the smartphone is configured on one specific network and nothing can be done with it.
Naturally, this problem has a solution, and today we will try to figure out which one. First, you need to understand the very term "unlocking a SIM card slot." This process is very simple and requires entering a special code using the telephone keypad. The main goal is to remove the lock and the ban on the use of other operator cards established by the manufacturer or seller of the phone.
If we carry out this action, it becomes possible to use SIM cards of any other compatible operators. But, it’s too early to rejoice and if you got the opportunity to use other SIMs - this will not provide you with full use of the phone.
How to determine if there is a restriction on the SIM card slot
First of all, you need to look into the package of documents that the seller provided to you at the time of purchase. If you meet the word "Unlocked" on any of the pages, it means that your phone is fully capable of working with any SIM cards of various operators. Another method is simply to contact the operator and clarify this information or insert another operator card and see.
Our official resource has collected even more detailed information about solving various problems that arise with smartphones. There are difficulties using the phone - rather, contact us and find out how to fix or prevent a more serious error yourself.
SIM lock, simlock, network lock or subsidy lock - This is a special type of phone lock, the essence of which is that the device can only work with SIM cards specific operator ( SP lock or Service provider lock) or within a specific country. About how to get around these restrictions (do sim unlock), you can read in this post, but first a few words about the problem itself.
On the Android smartphones are locked using two codes - country code (Mcc) and operator code (Mnc) At startup, the phone recognizes both codes indicated on SIM card. If they do not match the values \u200b\u200bset by the operator, then the device does not start and displays a message that SIM card not suitable. If both codes correspond to the specified parameters, then the smartphone boots in normal operating mode. It can also be used as a lock. Msin - code of each specific SIM-cards. In this case Android smartphone will only work with one single SIM-by card.
SIM lock It is often used by operators on phones that are sold for less than the factory price, but with the obligation to use a contract for the provision of communication services of a given operator for a specified time. Thus, the operator covers the costs associated with buying a smartphone and then selling it at a lower price: due to blocking Android the user simply cannot change SIM card, and use the services of a competing mobile provider.
To unlock Android smartphone ( sim unlock) you must use a special code. As a rule, upon expiration of the contract, the operator informs the user of it, but for this it will have to wait at least a year, or even two. But the problem can be solved much faster. Firstly, mobile operators sell unlock codes. Most likely, you just have to cover the costs incurred by the operator when selling the phone at a lower cost. You can also use special services and applications, but more on that later.
Separately, it is worth noting the legality of the procedure. In the territory of the CIS countries, there is not a single law that would prohibit sim unlock. Moreover, there is legislative practice in the world according to which the sale of phones with locked SIM cards prohibited.
The main ways to unlock Android smartphones (sim unlock)
This is an application that allows you to unlock smartphones and tablets. Samsung Galaxy (S, S2, S3, S4, Tab, Tab2, Note, Note2). In this case, no code is needed, and unlocking is carried out in a couple of tapas. The application itself is free, but you will have to pay to remove the restrictions. also allows you to create and restore backups Efs and provides full information about nv / lock.
Unlock.io from SDWebs
And this application works on a slightly different principle. It issues unlock codes. On the page in Google play it is written that from Sdwebs works with all models Nokia, Samsung, Sony, Alcatel, LG, Motorola, HTC, Sony Ericsson, Huawei, Blackberry, iPhone. Users complain that the cost of the service is too high, but this did not stop to collect more than 20 thousand installations. Payment is made through Paypal. And to get the code, you must enter data on the Android smartphone and pay for the service.
An analogue of the application described above. Gets an unlock code for the following Android smartphones:
- Samsung (Galaxy S2, Galaxy S3, Note, Note2 and)
- LG (Optimus L3, L7 and L9)
- HTC (One S, Inspire, Desire HD and Sensation)
- Motorola (RAZR XT, ATRIX HD, Defy mini, Motoluxe)
- Blackberry (Torch 9860, Curve 8520, Bold 9780)
- Huawei (Ascend, Huawei U8650, Fusion)
The cost of the unlock code in both cases depends on the model. Android smartphone and country operator. Payment is also made through Paypal. The only serious difference from that is that the application allows you to become a reseller and unlock other smartphones with it, making money on it. To do this, you need to contact the developers and activate a special account.
Suppose you decide to change the operator, but the new SIM card refuses to work on your phone. Frustrated, you call the support service and find out that your smartphone is blocked on the network of the first operator, and there is nothing to be done about it.
Of course, this is not entirely true. If you use an Android device (), you always have options.
Unlocking a SIM card is not a root
Before you start unlocking Android phones, let's briefly explain what network / SIM card unlocking is.
This is simply a process of entering a specially generated code through the keyboard of your phone to remove the restriction imposed by the operator involved in the distribution of the device. This will allow you to insert compatible SIM-cards of any other operators and use their services.
Unlocking with the purpose of using other SIM-cards does not give you full access to the phone. Unlocking the bootloader or rooting is another matter entirely. Both of these types of unlocking are legal, but operator assistance is often required to unlock a SIM.
Is your phone locked?
Not all phones are locked onto SIM cards of the same mobile network. To find out if this applies to your device, first look at the documentation. If the word “unlocked” appears in the receipt / invoice, you can be sure that the smartphone can be used with any operator.
Of course, you can contact your operator and ask if you are allowed to use SIM cards of other cellular networks. Or, try inserting another SIM card into the phone. If the card from another operator does not work, then your device is definitely locked.
Phones purchased directly from a manufacturer or a third-party retailer such as Motorola, OnePlus or Amazon for the full price (usually $ 500-700) are most often unlocked, unlike devices purchased from carriers such as Verizon, T-Mobile or AT&T at a subsidized price (from 0 to 200 dollars).
But if you find that your Android phone is locked to a certain operator / mobile network, how can it be unlocked?
SIM fraudulent apps
First, don’t look for unlock tools in the Google Play app store. Such services have a bad reputation, and most of them are simply involved in fraud. At best, they will not be able to unlock your phone.
In addition, you should avoid the “phone unlocking tools” presented on file-sharing sites or on Bittorrent networks. These utilities are most often infected with trojans and other malicious programs and are very rarely suitable for the phone you are trying to unlock (contrary to their description).
There are legal and safe ways to unlock your smartphone in order to use a different SIM card.
Surprisingly, you can contact your operator regarding unlocking your phone or tablet. In fact, this is your best option.
Starting in February 2015, mobile phone owners in America may ask their cellular networks to unlock their devices to switch to another service provider. This puts the United States on a par with the European Union (and repeals the unpopular law passed in 2013). In addition to this, operators are obliged to inform their customers about the possibility of unlocking the device by means of a note on a monthly account.
To get started, find out if your phone can be unlocked. If a smartphone is purchased under a contract, it contains the conditions for unlocking. If the initial two years have not yet passed, you will have to pay a fine for early termination of the contract. After that, you will receive an unlock code and you can safely use another SIM-card.
People who buy their phones directly need to wait 12 full months from the time of purchase and make sure all bills are paid. Then the network will provide you with an unlock code.
To unlock the network / SIM card, you will need to confirm the IMEI (international identifier of mobile equipment - a unique code used to identify your phone on any network) of your phone or tablet.
In Android, IMEI number can be quickly found by typing *#06# or by opening Settings\u003e About phone\u003e Status\u003e IMEI information. After transmitting this 15-digit number, the operator must provide you with a PIN code that allows you to use the SIM card of another network.
(This process may vary depending on the cellular network. For example, a new operator may require you to enter a special code to work with its network.)
This is especially useful if you travel to other countries, and your device does not support working with two SIM cards at the same time.
Although operators in America are not allowed to charge for this service, in the UK and Europe sometimes a small administrative fee is required to unlock the phone.
Find a Reputable Smartphone Unlock Service
If your network does not satisfy phone unlock requests, you can use one of the reliable online services involved in unlocking. However, finding such a service can be difficult.
We advise you to resort to the services of such services only as a last resort, if the operator refuses to help, and you have no other choice. On these sites, you need to enter IMEI to create an unlock code. But their activities are not regulated in any way, and although payment via PayPal provides you with some protection, they are not always reliable.
We have tested the sites www.safeunlockcode.com and sim-unlock.net in practice, but does not guarantee that they will work for your smartphone or tablet.
Have you unlocked your device?
Unlocking a smartphone or tablet is not an ideal solution for everyone. We recommend that you first weigh all the pros and cons of this process, and also think about what you will gain from it.
Does another operator offer better conditions? If you live in a large city, local Wi-Fi (secured via VPN) can be a much better (and cheaper) option.
