One of the main problems of Russian users is the Internet. Rather, its complete absence. It may be absent for a variety of reasons, but the worst is for those who live outside the areas of widespread use of sane providers. Of course, there is satellite Internet, but in our country it is so expensive that you can go to its use only from extreme degrees of despair.
But there is a better way and a little cheaper. As you can already understand, we are talking about USB-modems, especially popular recently. However, it happens that you have the modem of one company in your hands, and it catches a network of a completely different operator in your region. What to do? Buy a second modem? No, you can get by with a little blood, as the modem firmware will come to the rescue. This is an operation after which the obstinate device begins to calmly accept the SIM cards of another operator.
In addition, after the firmware, it becomes possible to fully work with the device. You can not only receive SMS, but also write them, and also get full access to the phone book located on the SIM card. Despite the fact that in most cases, “experts” scare novice users with the “incredible complexity” of this procedure, updating the modem is a fairly simple and fast operation.
So what do we need? First of all, the modem itself. Secondly, you need a computer and at least partially straight arms. It should be noted right away that you perform all manipulations with the equipment solely at your own peril and risk. If MTS modem firmware is detected, then the beloved by many cellular companies will immediately void the warranty.
Most likely, the IMEI calculator will be the subject of primary importance. Turn your modem upside down. See the number on its back? This is the desired value. Insert the SIM card of the operator you want, and then connect the device to the computer. Most modern modems will immediately require you to enter a special unlock code, which you need to generate yourself. How to do it?
Download the so-called IMEI calculator (there are a lot of them on the Internet), drive into it the same number that was found on the back, and then get the required code. In 97% of cases, the entire modem firmware is in this. If not, then “heavy artillery” must be launched. We are talking about specialized firmware that can untie the equipment from a particular mobile operator.
As a rule, these are installation files prepared by craftsmen, which automatically completely change the standard software of the device. Remember that before doing this, it is advisable to save all mutable files to the hard drive, since in this case you will have the opportunity to roll back all changes. This may be necessary if the modem firmware is not very successful.
In addition, do not forget to check all downloaded firmware with antivirus software, as some enthusiasts like to attach viruses to the archives with installation files and firmware. Apparently, as a gift bonus ...
Thus, the firmware of a 3g modem should not cause any particular difficulties to anyone who is at least somewhat versed in computer topics. There are no tricks in it, so you can immediately use the SIM cards of any operators.
