With

Let's say you decide to change your operator, but the new SIM card refuses to work in your phone. Frustrated, you call support and find out that your smartphone is blocked on the network of the first operator, and nothing can be done about it.

Of course, this is not entirely true. If you are using an Android device (), you always have options.

Unlocking a SIM card is not rooting

Before we start unlocking Android phones, let's briefly explain what network/SIM unlocking is.

This is simply the process of entering a specially generated code through your phone's keypad to remove the restriction imposed by the operator distributing the device. This will allow you to insert compatible SIM cards from any other operators and use their services.

Unlocking to use other SIM cards does not allow you to full access to the phone. Unlocking the bootloader or rooting is a completely different matter. Both of these types of unlocking are legal, but SIM unlocking often requires operator assistance.

Is your phone locked?

Not all phones are locked to SIM cards of the same mobile network. To find out if this applies to your device, first check the documentation. If the word “unlocked” appears on your 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 from other cellular networks. Or, try inserting a different SIM card into your phone. If a card from another operator does not work, then your device is definitely blocked.

Phones purchased directly from the manufacturer or a third-party retailer like Motorola, OnePlus or Amazon at full price (usually $500-$700) are often unlocked, unlike devices purchased from carriers like Verizon, T-Mobile or AT&T at a subsidized price (from 0 to 200 dollars).

But if you find that your phone is under Android control blocked to a certain operator/mobile network, how can I unblock it?

Fraudulent applications for unlocking SIM cards

First, don't look for unlocking tools in the store. Google applications Play. Such services have a bad reputation, and most of them are simply scams. At best, they won't be able to unlock your phone.

In addition, you should avoid “phone unlocking tools” presented on file-sharing sites or Bittorrent networks. These utilities are most often infected with Trojans and other malware and very rarely match the phone you are trying to unlock (contrary to their description).

There are legal and safe ways Unlocking your smartphone to use another SIM card.

Surprisingly, you can contact your operator about unlocking your phone or tablet. In fact, this is your best option.

Starting in February 2015, cell phone owners in America can ask their cellular networks to unlock their devices to switch to a different carrier. This puts the US on par with the European Union (and repeals an unpopular law passed in 2013). In addition to this, operators are required to inform their customers about the possibility of unlocking the device through a note on the monthly bill.

First, find out if your phone can be unlocked. If the smartphone was purchased under a contract, it contains unlocking conditions. If the initial two years have not yet passed, you will have to pay a penalty for early termination of the contract. After this, you will receive an unlock code and can safely use another SIM card.

People who bought their phones outright usually need to wait 12 full months from the date of purchase to ensure all bills are paid. Then the network will provide you with an unlock code.

To remove a network/SIM lock, you will need to verify the IMEI (International Mobile Equipment Identity - a unique code used to identify your phone on any network) of your phone or tablet.

IN Android number IMEI can be quickly found by typing *#06# or by opening Settings > About phone > Status > IMEI information. After transmitting this 15-digit number, the operator must provide you with a PIN code that allows you to use a SIM card from another network.

(This process may vary depending on cellular network. For example, a new operator may require you to enter a special code to use their network.)

This is especially useful if you are traveling in other countries and your device does not support two SIM cards at the same time.

Although carriers in America are prohibited from charging for this service, in the UK and Europe you sometimes have to pay a small administration fee to unlock your phone.

Find a reputable smartphone unlocking service

If your network does not support requests to unlock your phone, you can use one of the reliable online unlocking services. However, finding such a service can be difficult.

We advise you to use such services only as a last resort, if the operator refuses to help and you have no other choice. These sites require you to enter your IMEI to generate an unlock code. But they are not regulated in any way and, although paying with 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 we do not guarantee that they will work for your smartphone or tablet.

Have you unlocked your device?

Unlocking a smartphone or tablet is not perfect solution for each. We recommend that you first weigh the pros and cons of this process, and also think about what you will gain from it.

Another operator offers Better conditions? If you live in a major city, local Wi-Fi (secured via a VPN) may be a much better (and cheaper) option.
Have you unlocked your Android device? Tell us about it in the comments.

To date mobile phone is not just a means of communication. This is a multifunctional device, without which it is hard to imagine the average person’s weekday (or weekend) day. Now the phone can store a large number of confidential information, the publicity of which is absolutely not interesting to the owner. In this regard, you often have to block your phone and set different codes and passwords. But in the daily routine, you can easily forget assigned passwords. The code itself can also be accidentally installed by an inquisitive child or an acquaintance who sticks his or her nose where it doesn’t belong. This way, not only the phone, but also the SIM card itself may be blocked, after which you will have to rack your brains over the question “how to unlock the phone?” This problem is global, so phone manufacturers often provide a self-unlocking feature for phones. But before that, you need to figure it out and determine what type of blocking occurred and what exactly was blocked? To this end, we will divide our article into the following points:

Rescue a phone blocked by an operator.
Unlocking the phone, depending on the manufacturer.
Unlocking the SIM card.
Restoring the functionality of a phone whose memory has been blocked.

And now, in order.

How to unlock a phone locked by an operator?

This type of blocking is used by operators mobile communications for the purpose of making it impossible to use a phone (usually branded) in the network of another operator. If you insert another SIM card (from any other operator), then when you turn on the phone will ask you for a password or unlock code. Then the question arises: “how to unlock a phone code?” The best option, of course, if you have a fairly loyal operator who will kindly provide you with a code during a call to support. To do this, you will only need to name the IMEI of your phone (a number that is individual for each device, usually you can find it under the phone’s battery). But this is an ideal option, which is extremely rarely possible. If the operator refuses you, then do not despair, as there are plenty of craftsmen who can unlock your phone using flashing. Detailed manuals can often be found online, so if you have a sufficient level of knowledge, you can do this procedure yourself. But if you are not confident in your abilities and knowledge, then it is better to entrust this work to a specialist. Often, a jailbreak program is used for unlocking, which is supported by such a well-known company as Apple.

Unlocking the phone, depending on the manufacturer's brand

Many modern phone models support the function of protecting the phone using special passwords that the user sets independently. But there is always a risk of forgetting the code you set, which will make further operation of the mobile device impossible. In this case unlock phone You can use the firmware reset function. In other words, this is resetting all phone settings to factory settings. Of course, you will then have to make all the previously installed settings again, but there is no other choice. This type of phone unlocking is different for different manufacturers.

How to unlock a Nokia phone?

Nokia Unlocker Tool program, which should also be on your computer.

Next, launch the program, insert the cable into the computer and connect it to the phone. When the phone is recognized Nokia program PC Suite, you can run the NokiaUnlockerTool program. After this, the phone will be recognized by this program. Make a code request and the program should unlock phone. If this method does not help, then contact a phone repair shop or your nearest service center manufacturer of your mobile device.

How to unlock a Sony Ericsson phone?

In the case of phones from this manufacturer, two unlocking methods are possible: using the cable that was included with the phone and using a special service cable. For the second option, you will also need additional software (SEMCtool_v8.4 or TMS 2.45 program). If you plan to use the cable from the kit, you will need the WotanClient program, which, unfortunately, is not free. There are also some smartphone models that can be used with the DaVinci client.

How to unlock a Samsung phone?

Phones from this manufacturer are also equipped with an access lock function using a special security code, which can easily be forgotten... If just such an incident happened to you (well, or someone else blocked your phone, anything can happen) and you don’t know how to unlock your phone, then install a program called Samsung @ home 9.41 on your computer. With its help you can easily cope with this problem. The functionality of this utility is quite simple, and you can easily understand its settings.

How to unlock your LG phone

With phones from this manufacturer, everything is not as simple as with others. If your phone is locked, you can restore its functionality only with the help of special codes. The whole difficulty is that each model has its own code, so general solution simply doesn't exist. The only solution is to take your phone either to the store where you bought it (if the phone is still under warranty) or to a specialized service center. Only there they can help you.

Unlocking your phone's SIM card

A small plastic card with a chip in the middle is an irreplaceable device without which a mobile phone is simply useless as such. We are talking, naturally, about a SIM card. The chip that it uses, although small sizes, but allows you to store a certain amount of information, which is often confidential. To ensure the safety of this data, protection technology is also used using the so-called PIN code, which is requested when you turn on the phone. If you enter your PIN code three times unsuccessfully, then mobile device will ask you for another code, the so-called PUK code. It usually consists of eight digits and is provided to you along with the SIM card. If you cannot use your phone because you do not know the PIN code, then simply use the PUK code. If you don’t know it either and it’s not written down anywhere (and the documents from the SIM card are lost, for example), then the first thing you need to do is call the support number of your mobile operator. There they will tell you how to find out your PUK code (you may even be able to find it out over the phone). If there is no way to call, then contact the nearest customer service center, taking with you the SIM card and the phone in which it was used (you may also be asked for a passport). You can look at the numbers of mobile operators in Ukraine, as well as how to quickly contact them.

Unlocking your phone memory

Some phone models allow you to separately block access to various files that are located in the memory (either the phone or, most often, an additional memory card). In this case, again, a situation is possible when you will not know (or remember) set password and the functionality of the device will be partially unavailable to you. It is very unpleasant when the information you need seems to be at hand, but at the same time is not available to you. To solve this problem, you will have to worry about unlocking the memory card. There is such an option as formatting, which will allow you to quickly resolve the issue of ignorance of the code. But it will not solve the issue of information recovery, since all of it will be destroyed as a result of formatting. Therefore, this option is not suitable for everyone. All other methods that allow unlock phone memory, are based on the use of additional software. To do this, you will need the cable that came with the phone (or was purchased by you additionally) to connect it to the computer, or a card reader ( small device, which will allow you to read information from a memory card by connecting it to a computer separately from the phone). One of the programs that can be used to unlock is JetFlash Recovery Tool. You can download it from the official website of the developers. It can also be used to format a memory card.

The main thing is that you are aware of all your actions and understand perfectly what you are doing. Otherwise, you can simply disrupt the functionality of the phone, which cannot always be restored. So if you don't know yourself how to unlock your phone, perform any other action with it, then it is better to seek help from professionals. But I still hope that you will not encounter such problems and will handle your telephone wisely.

Did you enter the pattern key incorrectly? Is your phone blocked? We'll show you how to unlock it

It also happens that you forgot the pattern key (or you found a phone that is locked using the pattern key) and cannot unlock your phone. An unpleasant situation, of course. In this case, as in all others difficult situations, the main thing is not to panic. A couple of minutes, the correct query in the search and you can restore everything yourself. To simplify this procedure, I scoured the Internet and found several videos for unlocking phones from different manufacturers. You can find them below.
