Possible problems and solutions

The first difficulties, as a rule, appear at the stage of installing programs. Antivirus software can recognize the software as a virus and does not allow it to be installed on a PC or laptop. In this case, it is better to disable the antivirus. There is another reason that does not allow you to change the IMEI on the modem.

1. Check the software. It shouldn’t be open. When working in the background, the program sends commands to the COM port, which causes difficulties in operation.
2. Enter the Task Manager and close unnecessary processes mentioning software.

If the above steps do not produce results, and replacing the IMEI on the modem is impossible, go to the Internet and find the official firmware for the model you are interested in. Next, close the DC Unlocker program and run the firmware. At the stage where you need to specify the Flash code, do not enter it, but simply close the software or click on the cancel button.

Why change imei on the modem?

Today, almost all operators offer unlimited tariffs. The most advantageous offers are from Yota, Beeline, MTS and other operators. There is only one minus. The applicable tariff can only be used on a phone, but may not work on a modem. Here we are getting closer to solving the question of why change the IMEI of the modem.

Let’s look at an example. A person bought a tariff from one of the providers to gain access to unlimited Internet. He inserts the card into the modem and uses it to surf the Internet. After this, the operator contacts the client and asks to move the SIM to the phone.

In this case, you can change the IMEI of the modem and thereby solve the problem. A similar output is also relevant for those cases when it is necessary to use the tariff plan of another operator, and the USB modem is “firmware”. In other words, replacing IMEI allows you to expand the capabilities of your equipment and get rid of company restrictions. For example, if you need to bypass the restriction on Internet distribution from MTS “Unlimited”.

This instruction will also be useful to you if you decide to use the modem as a telephone.

How to change imei on a modem: simple instructions

Note that IMEI is a unique number consisting of 15 digits. It is provided for phones, USB modems and other devices. The presence of such a code allows the SIM card to recognize the type of equipment and decide on the possibility of “cooperation”. In simple words, this is an individual device identifier by which it can be found.

Now let’s look at how to change the IMEI of a modem using the example of a product from Huawei. If you do the work according to the above points, changing the individual code will not be difficult. The instructions are provided for the E3372 model, but they can also be used for other Huawei devices.

To change IMEI, follow these steps:

• Copy the key to unlock. In many cases, V201 code is suitable. Try it first, and then test other options, for example, V1 code or V2 code.

• Enter the DC-Unlocker program and paste the code into the special column. There should be a line here at^datalock=»CODE». The word “CODE” must be replaced with the data mentioned above.

How to find out the brand of your phone: Honor and Huawei

First of all, let’s study ways to determine the model of a Huawei smartphone. Some allow you to verify information through system settings, while others require the original box or documentation.

How to find out the product code of a Huawei device?

The gadget product code is designated – Product Code or P/c. It is a service code and is located on the label next to the barcode. You can view this information in a special menu — in the engineering menu. But, this section can be called up differently depending on the smartphone model. Usually the command *#*#1357946#*#* is used, if it does not work, then look for the combination on the Internet for your device.

The serial number includes model information and manufacturer information, so you can know the authenticity of the smartphone. You can see the S/N on the packaging (near the IMEI), in the documentation, or under the battery when removing the cover.

How to find out your imei?

You can find out the IMEI of your device in a bunch of ways. On the phone itself you can dial *#06# or look into the settings, phone information:

Android: “Settings” – “About phone” – “General information”

iPhone: “Settings” – “General” – “About this device”

IMEI can also be found on the device box. And the most hardcore detectives can find the IMEI under the battery.

Let’s see what else is interesting on the box? By the way, if you find two IMEI numbers at once, this means that you have two SIM cards in your phone. Or one regular SIM card and one eSIM. Here’s how it is on this iPhone, for example.

By the way, the EID number on top is the identifier of the built-in SIM card. To activate the built-in SIM card, the operator must receive your EID number (Embedded Identity Document), after which he can assign a phone number to it.

And the MEID code is essentially the same as IMEI only for CDMA networks. Therefore, if you see such a code, it means you can easily travel to America with such a phone, where CDMA networks are common.

Fraud

But if you are selling a phone. Is it safe to send such valuable information to a stranger? How can I tell you? In general, yes it is safe. But there is a risk of falling into an unpleasant fraudulent scheme.

You send your IMEI to a potential buyer, and in response he sends you a link to that very dubious site sndeep.info. Where does it say that your IMEI is now listed as stolen.

And in order to remove IMEI from the list, they require a certain amount of money from you.

The only problem is that this site is for informational purposes only and anyone can enter any IMEI there, indicating that the phone is lost or stolen. This doesn’t affect anything.

Keep this in mind and don’t worry if you fall for such a scam. Unfortunately, this often happens when buying/selling used equipment.

iPhone model number

By the way, when buying a used iPhone, you can also check the model number in this format:

It can be viewed in the “About this device” section.

The first letter in this number is responsible for the “status” of the device.

For example, if the first letter is M, it means the device is new. And if F — the phone is refurbished.

Here are all the letters and their meanings:

And by the last two letters you can determine the region:

Judging by the statistics of the Russian portal for checking IMEI, the most popular used devices in Russia are iPhones. Therefore, I think that the information will be useful to you.

Bypass operator lock

Operators receive information about the fact of using the Internet on the phone through TTL indicators. It is different for each device, and after specifying it, each traffic packet is reduced by one when passing through the router. In order to make traffic readable, you need to use a special utility or contact your operator.

Determine the smart watch model

It will be even more difficult to recognize a Smart watch by its appearance, because their design is very similar to each other.

Let’s look at the numbers

First, a little numerology!

IMEI consists of 15 digits and contains a lot of useful information, where the phone was made, what model it is, what its serial number is.

TAC — Type Approval Code — the first 8 digits of the number. And it, in turn, consists of two parts.

The first 2 digits are called RBI — Reporting Body Identifier — and indicate the code of the GSMA authorized representative. That is, the company through which the new model is submitted for registration with the GSMA? This must be done for each model.

For example, if the first two digits of the IMEI are 35, then the model was registered in Britain.

The next 6 digits are the model serial number. It is determined by the manufacturer and must be unique for each model.

But the most interesting thing is that one TAC only applies to 1 million devices. And if more is needed, the manufacturer must register a new TAC.

How he will do this is his choice: either through another registrar (then the first 2 digits of the IMEI will be different) or by assigning a new serial number.

Thus, the TAC number in the same model may change from batch to batch. Therefore, if you meet a person with the same TAC number, know that this is fate! There are 2 of you in a million.

And the last digit is the control digit. It checks whether the IMEI is correct, and it is calculated using the Luna algorithm.

You can also find another number in the device information — IMEI SV. What is this? In fact, this is also an IMEI, even the first 14 digits are the same as in a regular IMEI.

Recommendations

Carrying out the transformation into a phone will require:

• special plug;
• shielded cable and connector.

For a reliable connection between the cable and the modem, it is necessary to tighten the screws on the connectors.

To prevent voltage surges, connecting the modem transformer should be done using special devices and then connecting with a cord.

After installation, you should connect to the telephone network.

Since the modem has two telephone connectors, one of them is connected to an additional telephone (it is preferable to use an adapter).

When connecting an additional device, the quality of communication may deteriorate significantly.

Change imei

And, by the way, IMEI can actually be changed, and in Russia it is even legal. This is necessary, for example, if the phone was lost or stolen and the original IMEI was blocked.

In order to change the IMEI on an iPhone, you need to write to Apple support and collect a bunch of documents.

And on Android, theoretically you can change the IMEI yourself, but on rooted devices. But we, of course, do not recommend doing this.

Method 1 – packaging

The first option requires a box. Pay attention to the label on the side of the package, the necessary information is there.

If you have any questions or complaints, please let us know

Ask a question

Method 2 – marking on the back cover

The second option involves disassembling the device, or rather removing the back panel. Attach a suction cup to it, then lift it and place a pick or plastic card into the resulting gap. Run this tool around the entire perimeter of the cover to release the clips. The information is located on the battery, but if the battery is removable, the markings will be located under it.

Method 2 – marking on the body

The second option is to look at the label that is glued to the outside. Depending on the watch series, the sticker is located in the following places:

Method 3 – system settings

Another simple option that allows you to find out the model of your Huawei and Honor phone without documents is to use the parameters. Instructions:

“Access to the network is closed. Connection failure» on Honor and Huawei: reasons, how to fix it? If you see two IMEI numbers, it means you are using two SIM cards. You can also check the identification code by entering the command — #06#.

How is imei useful?

So why do we even need to know IMEI? There are two scenarios in which IMEI can be very useful:

First. When purchasing a used model or a new phone at unofficial locations. For example, if we take a used device, we can find out:

It will also be possible to check this original device or a copy. What is useful when ordering devices from China. We’ll tell you how to do this later.

And the second scenario. If you have lost your phone or had it stolen. Using IMEI it will be possible to calculate the location of the device. As soon as the device turns on, it will immediately register on the network.

Results

Having at hand information on how to find out the IMEI of a modem and change it, you are no longer tied to a specific operator and tariff plan. Now you can use a USB modem with your phone’s SIM card without worrying about blocking the device or switching to a more expensive tariff.
