Unlocking the modem is to untie the operator's SIM card from the device in any way. The fact is that most of the devices run on customized firmware with a link to the provider. Because of this, the device is not able to function with cards of other operators. Examples of such modems include products from ZTE, Huawei, MTS and Kyivstar.
In order to unlock the modem, you need to use a special method. There are both paid options and free ones. An example of the first method is the DC-UNLOCKER program.
Unlock programs

There are hacked versions on the Internet, so in order to save money, they are the most suitable. But you need to trust the source from which the download occurs. Quite often, instead of this program, the so-called killer is distributed. After using this program, the modem stops working.
DC-UNLOCKER
Not always free methods can help, but there are still several working options. If they do not work specifically on any modems, then even then you should seek help either from a specialist or from the DC-UNLOCKER program. Problems may arise with Kyivstar and MTS devices. Unlocking the modem and any flashing is prohibited due to the factory lock. How to understand that the device belongs to such? If IMEI starts at 359, then you already need to be wary - most likely, it will be quite difficult to unlock the modem. In any case, you can try.
The cheapest and simplest options are the easiest to "free" from the binding. They usually requirethe usual unlock code when connecting someone else's sim card. It can be both purchased and calculated using methods on the Internet. Calculators and similar programs are freely available on the Web, so unlocking such a modem will not require much effort and time.
HyperTerminal
There are models with a ban on entering the code. Then the program for unlocking the Hyperterminal modem will come to the rescue. It needs to be activated. In the "Start" menu - "Accessories". In this section, you should find "Communication", this is where this software is located. After it starts, you need to select your modem in the list and click "Connect". The bottom line will appear. You should write the AT command in it, press the send button.
Unlock ZTE MF180 ("Beeline")
When connecting the modem to a computer, you need to install software called "Beeline USB modem". Unlocking can be done through it, or through some other unofficial utilities, for example, MTS Connect Manager. For the successful completion of the process, the PCUI. VN file is required, which will avoid incompatibility of versions of pre-installed software, firmware (described above), QPST package. All this can be easily found on the Internet in a second.
To unlock the ZTE modem, it is best to use a laptop with an operating system from Windows. First of all, you need to install the QPST application. Next - get all the files from the desired firmware. Modem followsconnect to a laptop and install a regular program from the operator. Be sure to go to the device manager and check whether all drivers and virtual utilities have been installed for this particular device. Next, you need to remember which COM port is connected to the modem, this will come in handy when working with QPST. We launch the last program, enter into it the connector to which the virtual interface is connected. The next step is to create a new port. It synchronizes with the COM connector. Next, through the "Standard" in the "Start" menu, you need to launch EFS Explorer. Then you should confirm the selected port, and the program will open the modem files. There must be a PCUI. VN file in the device memory. If it is missing, then it should be added. Then you need to drag it into the program window.
Work with the EFS Explorer program is over. Now you need to run the firmware from MTS. It is factory installed and does not require additional installation. If you have problems starting, you can try to open it as "administrator".
Immediately after that, the flashing of the device will begin. The maximum time it takes to do this is 20 minutes. Do not interrupt the download - 90% chance that the modem will not turn on after that.
After the flashing is successful, you need to remove the software from Beeline from your computer. Now you can use the services of any operators without any restrictions. If you connect the modem again to the computer, "MTS Manager" will be installed.
Also, do not forget that you need to configure network profiles. It is especially important to register the operator's APN. If the network is available without preliminary settings, then the last parameter is unimportant.
Modem unlock for all operators
Using the example of HUAWEI E173, you can explain how the unlock occurs immediately for all possible operators.
It is necessary to find the firmware that best suits the needs of the user. Ideally, you can easily find a manager on the Internet that allows you to use the Internet, send and receive SMS, MMS, voice and video calls. Below we will consider detailed instructions on how to unlock a Huawei modem. Before starting the process, it is necessary to install the factory manager, otherwise an error will occur during the flashing. The fact is that it installs drivers into the system that allow you to contact the modem and perform all the necessary manipulations. Next, you need to reflash the manager itself to the one you need. After this is done, you need to check if the modem works with other operators. If not, follow the instructions below. There are two options for solving the problem. Check them out below.
Option 1
You need to download the connection manager, which initially changes the operator's settings on its own. After correct installation, when changing the card, a window will pop up asking you to enter the unlock code. This can be “cured” using a program that generates code according to IMEI. There are many working options on the Internetboth paid and free.
Option 2
First you need to check if the router is unlocked. This can be done either by using a third-party card from another operator, or by using special programs. Next, thanks to Huawei Modem Unlocker, you need to create a special code like NSK. It's just for unlocking. After entering it, you can freely work with any operator.
