Like the Chinese counterpart from Huawei, the MTS 827F comes in the following form:

  1. Actually the modem itself.
  2. A coupon with a warranty period of the manufacturer of 12 months.
  3. Extended manual.

In some cases, this list is supplemented with a starter pack, and it is in this form that such a device is most optimal to acquire. But the CD with the management software and utilities is not included in the delivery list for the reason that all this software is inside the modem. Also on this integrated memory chip can be found and documentation.

Nominally, this modem model is designed to install the SIM card of the MTS operator in it. Then it can be used to both send and receive information from the Internet using the cellular network of the company of the same name. But if necessary, there are special software tools that can be used to eliminate such “binding” of the modem to the MTS equipment.


The presence of the following technical specifications boasts MTS 827F:

  1. Antenna type - integrated. But it is advisable to use it only in large cities. Also, the presence of a communication socket CRC9 allows you to switch an external amplifier in conjunction with an external antenna.

General setup procedure

The corporate modem considered in this material, when connected to a PC or laptop, is configured as follows:

  1. We get this solution out of the package.
  2. Next, you need to remove the protective cover from it, behind which you can find the communication port for connecting to a personal computer. The latter is installed in the socket of a personal computer USB format.

About modifications

By default, the hero of this article can work only with MTS SIM cards. This restriction comes from the software that is wired by the operator in the modem. But it is possible to modify it and due to this unlock the MTS 827F. But, again, this operation is done at your own risk and, of course, at risk. It may be easier to overpay a certain amount and purchase an already unlocked such device from Huawei.

There are two submodels of such modems. One of them is labeled E3372h, and the second - E3372s. They are incompatible with each other, and in each case their own unlock order. In the first group of solutions, the serial number starts with G4P, and in the second - L8F.

Unlock E3372h

First you need to determine the software version of the device. To do this, download the program Huawei Terminal from the Internet and install it. Next, you need to run it and type in the command line: “АТ ^ VERSION?”, And after that the current firmware version of this solution will appear.

If it is 2Х.180, then in the same program just type the following command: “at ^ nvwrex = 8268,0,12,1,0,0,0,0,0,0,0, a, 0,0, 0 ”. Further pressing the “ENTER” button will unlock this solution.

In later versions of this solution, it is necessary to download a special calculator from the global web. Then install a SIM card of another operator in the modem slot and connect it to the PC. Next, you will be prompted to enter a special code. Now you need to run the previously downloaded calculator and enter all the necessary values ​​in its fields. In response, a special code will appear that you need to enter in the query field. After these manipulations, the device ceases to be tied to the MTS equipment and can function in the cellular network of any mobile operator.

Unlocking E3372s

Unlocking MTS 827F version E3372s is a simpler operation. In this case, you need to perform the following actions:

  1. We install the software packages PC-UI Interface and DC Unlocker, which are previously downloaded from the Internet.
  2. Next, download Huawei Terminal and install it.
  3. Then run the previous program. In its command line we enter: “at ^ nvwrex = 8268,0,12,1,0,0,0,0,0,0,0, a, 0,0,0”. Then click “ENTER”.
  4. After this fairly simple command, the device can already work as part of any cellular network.

All commands need to enter as accurately as possible.If an error is made somewhere, the device will lose its efficiency completely and irrevocably.
