Dense urban development, terrain, power lines and remoteness from transmission towers greatly affect the quality of signal reception, which can disappear at the most inopportune moment.
And today I want to talk about several ways to enhance cellular communication on the phone with your own hands and how really they help. But before you perform any actions with your device, you need to make sure that it is working.
After all, poor reception may be due to a malfunction of the radio module, unreliable contact with the internal antenna, or firmware that has flown down.
Making sure that your smartphone is working is very simple. It is enough to compare its reception level with another, obviously working, not necessarily of the same model.
If it is very different, then most likely the mobile phone is faulty and it has a direct road to the repair shop. But there is no need to rush. I had a similar situation with Lenovo 316i, when the level bars on the display constantly disappeared, while other mobile phones worked fine. For some reason, I sinned on the buggy software.
And, of course, I tried to reflash it, but the result did not change. Having studied a considerable number of forums, I was inclined to the conclusion that the cause of poor reception may be poor contact at the junction of the antenna and motherboard.
This is a common disease of Chinese gadgets. The next step I decided to take was to disassemble it.
And in fact, having opened the case, I found that the middle spring tab on the board is slightly bent down and does not come into contact with the antenna, which is a flexible cable glued to the cover.
Armed with tweezers, I bent it up a little, screwed everything back on, replaced the SIM cards, the battery and pressed the power button. After the system booted, all four divisions appeared in the status bar and this time they did not disappear.
Thus, having skills and certain knowledge, I myself managed to repair my mobile. But now let's talk about the methods by which you can significantly improve the quality of communication.
Software way to amplify a cellular signal
This time we will not disassemble anything, but install it on Android special application MTK Engineering Mode, with which we will enter engineering menu and change some parameters there. It is free and you can download it from the Play Market. Please note that it is only suitable for devices based on the MediaTek processor. You can find out which processor you have using the CPU-Z program, which you can download, again, from the Play Market. So, we click on the shortcut of the program and immediately get into such a menu.
Go to the MTK Settings tab
As a result, we will see such a window with settings on the display, where we remove all the checkmarks. We leave only
- EGSM900;
- DCS1800;
- WCDMA-GSM-900.
Thus, we turn off unnecessary frequencies that are not used in our country.
We do the same operation with SIM2.
Then we go to the “Network Selection” where we select the GSM only item. This is a 2G communication standard, which originally appeared when building telecommunications networks.
It has wide coverage across the country and handles voice calls very well. Select this tab if you do not use 3G internet.
After these manipulations, your handset will work longer by turning off scanning of unnecessary frequencies and keep the radio signal more stable, as it will not jump between WCDMA and GSM standards.
Connecting a homemade antenna
Before Cell Phones they had an external radio antenna or a plug-in connector located on the back of the case, into which any piece of wire could be plugged, which significantly increased reception.
Now everyone has modern smartphones, to which, apart from charging and headphones, nothing can be connected anymore. But, if you disassemble it, then inside, on the board, you can see a small golden cylindrical connector with a hole in the middle.
It is intended for network diagnostics and is used only in service centers. But, if you insert a small piece (no more than 5 cm) of a thin insulated wire into it, you can observe a noticeable increase in the signal level.
Only in this case it is necessary to comply with certain conditions. The wiring should not bend anywhere and touch the current-carrying parts. You can carefully lay it inside the case, between battery and cover.
Again, this method is not suitable for everyone, since most devices are non-separable or do not have such a connector.
Installing a repeater
This option is ideal for use in the country or in the countryside, where, as a rule, the quality of communication is not important due to the remoteness of the towers.
Its principle of operation is to capture electromagnetic waves, preamplify them and transfer them to the user's phone. The system consists of a block - a repeater, an external and internal antenna. The disadvantage of this equipment is the expensive price of the device, the complexity of installation, configuration and a small radius of action. But you can try to build a home-made installation to amplify the signal yourself.
To do this, we need a metal rod, about 50 cm long, a coaxial cable, a piece of foil about 100 by 40 mm in size, glued to plastic or plywood. It would be better if you have foil textolite.
So, we bend our rod in the shape of a rhombus and solder a cable to it, the other end of which is soldered to the foil.
An example of connecting a cable to a rod We install our rhombus on the roof of the house or on a pole, preferably higher.
Now let's check the amplifier. To do this, we put the phone close to the plywood and notice how much the signal quality has improved.
sticker sticker
Often on sale you can find a universal compact antenna amplifier, which is a thin self-adhesive plate with a special geometric pattern of metal tracks, which, according to the manufacturer, reduce the amount of interference and can significantly enhance the signal where there is practically no cellular connection.
The sticker is glued to the inner surface of the phone, under the battery. But to buy it, in my opinion, there is no point. With the same success, you can put a piece of foil under the battery and the effect will be the same.
Here, with the help of such simple manipulations, you can do it yourself, with the help of inexpensive materials, to amplify a weak cellular signal on your phone.
P.S. I am attaching a screenshot of my earnings in affiliate programs. And I remind you that everyone can earn money in this way, even a beginner! The main thing is to do it correctly, which means to learn from those who are already earning money, that is, from Internet business professionals.

Despite the widespread use of mobile communications, the question is still relevant how to strengthen the signal of the phone, or rather cellular communication, to which it is connected. It doesn't matter if you live in a small village or in a metropolis, the chance that your device will stop receiving a signal is everywhere. Gradually, this problem is solved by operators, new base stations appear, communications are increasing. But what if the problem lies in your phone, and not in the network? Today we decided to figure out what the bad signal level is connected with and whether it can be fixed by hand.
The principle of operation of cellular communication is quite simple: there is an operator’s base station and your phone, a radio frequency channel is organized between them, through which SMS messages are transmitted, calls are made, and Internet data is exchanged. There are several cellular communication standards that differ in signal transmission method and frequency. As a rule, base stations are built on hills in order to provide maximum coverage. However, you can’t get away from the barriers that prevent the passage of the signal. These can be walls, trees, and other obstacles, upon contact with which the signal weakens.
It is clear that in open areas where high-rise buildings do not abound, the coverage area will be higher. For example, for stations operating according to the GSM-900 standard, in this case, the zone is no more than 30,000 kilometers. In urban areas, the figure is reduced to 7 kilometers. Stations with more advanced communication standards in the face of 3G and LTE cover an area half the diameter.
Why do we have a weak phone signal?
Due to the above mentioned barriers, so-called dead zones or holes in the coating can be formed. That is, places where the signal is weak, unstable or completely absent. Where do you most often encounter poor signal strength on your phone:
- places located at a significant distance from the nearest station (there is simply no coverage);
- basements, underground parking, lowlands (the signal is simply unable to penetrate here);
- hills, skyscrapers (often "to rise higher" does not mean the obligatory presence of a signal - above the 12-14th floor there is often no signal at all);
- buildings made of metal structures that do not transmit a signal.
However, obstacles and distance from the station are not always the reason for the lack of a signal. Often the user's phone becomes the cause. You have probably been in situations where a friend has a cellular signal, but you do not. And at the same time, you use the services of one operator. There are cases when different signal levels are observed on two identical phones. There can be many reasons:
- a phone in a metal case or in a metal case can catch the network much worse than a plastic device;
- quite often, no matter how surprising it may sound to you, the reason is the “clumsy” firmware of the phone;
- damage to any components as a result of falls, immersion in water, and so on;
- the phone may have a defective antenna from the factory, which is especially sinful for Chinese manufacturers of inexpensive models.
How to strengthen the phone signal with your own hands?
So, let's go over the theory, let's move on to practice. We will analyze several ways to boost a cellular signal, starting with the simplest, ending with quite complex and expensive ones.
Reason for the firmware
It's worth starting with checking the correct operation of the software before trying to get to the insides of the phone. With the deterioration of the communication signal that appears after flashing, hundreds of users are faced, so attention should be focused. We have already written, so we will not repeat ourselves. Firmware is a fairly simple process, but with its own nuances. Most importantly, remember to back up your important files.
If the flashing helped, then we congratulate you, but if the phone still does not catch the network well, then proceed to the next step.
Poor signal reception due to damage to the phone
As already noted, often the phone does not pick up a signal well after it accidentally fell on a tile or plunged into the sea. In this case, the average user has no choice but to go to a service center. Modern phones are quite complex devices, therefore it is not possible for most to identify the source of the problem on their own. It is likely that specialists will detect damage and perform the necessary work so that your phone can again cope with network searches without any problems.
How to boost your phone signal
In most cases, the cause of a weak cellular signal lies in the defect of the antenna, which, in fact, is responsible for this function. Often, owners of inexpensive smartphones from the Middle Kingdom are faced with the fact that the manufacturer cheated a little by loosely connecting the antenna to the device's motherboard. You can fix the mistake yourself, but you need to understand at least a little how the phone works. Otherwise, please contact service center with a description of the problem.
- now smartphones are represented by a very different design, and therefore they are disassembled in different ways; it is easiest to get to the insides of a phone with a removable cover and battery, it is more difficult when the smartphone is not collapsible;
Take your time. Before starting disassembly, find a video or text material on the Internet that will show and tell how your particular device is disassembled, what you should pay attention to.
Please also note: after disassembling the smartphone, you lose the warranty.
- as a rule, the antenna is hidden in the lower or upper part of the case, represented by small copper strips (again, for the location of the antenna specifically in your model, see the relevant materials);
- after you get to the board, you will find several spring contacts, which should fit snugly against the cable located on the back of the structure;
- if the spring contacts of the motherboard do not adhere well to the cable, carefully correct them, armed, for example, with tweezers;
- collect the phone and enjoy good signal networks.
We connect a homemade antenna to the phone to amplify the signal
The methods discussed above only work if the problem lies in your phone. But, as we noted at the beginning of the material, the cause of a bad signal can be various kinds of obstacles or a significant distance from the station. In this case, you can try to strengthen the antenna of our device with just a piece of wire.
Just note that the method is not suitable for all phones. The fact is that for its implementation you will need a special diagnostic port, which is difficult to get to in a modern non-separable smartphone (in a number of models you can’t find it at all). It looks like a small round connector of golden color.
take a small piece of thin insulated wire;
insert into the connector;
lay it so that it does not interfere with other components and closing the lid.
Everything, as practice shows, the signal of the phone network is amplified to a large extent. Isn't it surprising?!
Some users inserted a piece of wire into the 3.5 mm port (for headphones). Sometimes that works too.
Sticker sticker or foil to boost phone signal
In the vastness of foreign online stores, it will not be difficult to find a bunch of different devices for signal amplification. Among them, a small sticker-sticker is popular, which is a few metal tracks, which, according to the manufacturer, allow you to get rid of interference.
Similar stripes can be seen in some smartphones by default, so the "magic" properties of the sticker have the right to life.
However, to achieve a slight improvement in the signal, according to a considerable number of users, a piece of ordinary foil will help. It is located under the cover of the phone, closer to the antenna. The method is simple, so you can try.
Strengthening communication with a repeater
In some cases, when the signal cannot be amplified by any of the methods (too thick walls of the room, remoteness from the base station), they resort to the use of special antennas or repeaters. Similar devices are capable of greatly amplifying the signal, but their cost often scares away a potential buyer.
Where to buy cheap?
You can build something similar with your own hands, but often it does not amplify the signal at all or does it very, very badly.
For example, some use the following method:
- we take a metal rod (50 cm is enough), a coaxial cable, a piece of foil (about 10x4 cm) and plywood or plastic;
- we bend the metal rod so that we get a diamond-shaped design;
- glue the foil to the plywood;
- we connect the metal rhombus and the foil using a coaxial cable (solder);
- the end, on which the rhombus turned out, is raised higher, the other, with foil, is left below;
- We bring the phone to the foil to check the signal quality.
It will probably be necessary to find the most suitable place for the resulting structure to catch the signal.
It is clear that such an amplifier is unlikely to provide communication to a large company that was not lucky enough to have an office in an area without network coverage. Here you will have to seek help from specialists. Today, many companies provide similar services, and not only will offer modern equipment, but will also be engaged in installation. By the way, you should not save on specialists - for installation, workers use special devices that help determine the most suitable place, select frequencies, and so on. For an ordinary user, of course, it will be difficult to cope with such a task.
The positive thing is that engineers have already come up with several options for getting rid of such inconveniences. The disadvantages include the requirements for additional financial investments and the complexity of setting up communication amplification systems. However, let's not get ahead of ourselves and tell about all this in order.
Mobile phone signal booster
The simplest option to avoid a weak signal is to install the amplifier not on a certain area or building, but on a specific phone. Similar antenna amplifiers look like stickers and are glued inside the body of the device or on its back cover.
Amplification of the signal occurs due to a change in the radiation pattern of the phone's own antenna and an increase in the total induction of the two antennas.
The disadvantage of this method can be considered a change in the circular reception of a mobile phone to a narrowly focused one. Simply put, the signal will improve significantly when you point the phone towards the tower of the mobile operator. In other cases, the signal quality, on the contrary, will fall. How effective is such a signal amplifier mobile communications for you personally, it is worth, of course, to decide on your own.
The next way to enhance the quality of communication is a point-to-point mobile signal amplifier with a small coverage radius. This option is suitable for cases where the strong signal zone is only a few meters from your workplace.
Despite the widespread use of mobile communications, the question of how to strengthen the signal of the phone, or rather the cellular communication to which it is connected, is still relevant. Whether you live in a small village,...

Programmatic way
Not everyone can afford to buy a phone with enhanced signal reception. To try to improve the performance of Wi-Fi, 3G and 4G, owners of smartphones and tablets based on MediaTek processors can use MTK Engineering Mode. The program must be downloaded for free in the Play Market. Steps after installing the software:
- Go to the Telephony tab, select Band Mode.
- Click on SIM1. Remove all checkboxes in the settings, except for EGSM900, DCS1800, WCDMA-GSM-900. This disables unused frequencies in Russia. A similar setting is made for SIM2.
- Next, you need to go to the "Network Selection" item, and install GSM / WCDMA auto. Then, when the phone is working, the 2G signal will not be lost.
- If you select GSM/WCDMA (WCDMA preferred), the device will try to connect to 3G networks, but there may be interruptions in GSM operation.
Internet Speed Master application using ROOT rights
When the reception of web data on a smartphone slows down, users begin to blame the operator and the selected tariff plan. The Internet Speed Master application can improve the situation. The user must first root the phone, otherwise the software will not change the system files. The procedure after obtaining root-rights on android:
- Log in to the program, grant superuser rights.
- Go to the ApplyPatch tab, restart your smartphone. The signal amplifier will then work.
- If you need to restore the old settings, you need to go to the main menu of the program, click Restore.
Many craftsmen are trying to create a 4g signal amplifier for the phone on their own. The efficiency of a homemade antenna is at the level of the initial ready-made signal amplifiers. To create a device, you will need an antenna from an old radio, copper wire no more than 4 mm thick, a screwdriver, a small washer, and soldering accessories. Procedure:
- The antenna is disassembled at the base.
- Solder the wire to the washer.
- The washer is carefully screwed back to the base of the antenna.
- Some craftsmen advise making a foil reflector to further enhance the signal. As a base for the reflector, you can take a sheet of cardboard. You need to glue foil to it. For convenience, you can purchase foil fiberglass. The reflector is placed behind the antenna.
- The finished amplifier can be connected to a phone or to a 3G modem:
- It is necessary to remove the back cover of the smartphone, find the receiver connector or to connect the antenna. Strip the wire, and then connect to the hole.
- If the modem has an input for connecting a third-party antenna, the wire is connected there. In the absence of a connector, the first third of the device is carefully wrapped with wire.
How to strengthen the cellular signal in an apartment or country house through a repeater
The coverage area of Tele2, MTS, Megafon, Beeline formally includes all the settlements of Russia, but in villages far from cities, GSM and 3G do not work so well. You can increase the strength of the incoming cellular signal using a repeater. The device consists of internal and external antennas, a repeater. A homemade passive repeater can be done like this:
- Take 2 wires 4-5 mm thick, make a circle out of them.
- Homemade antennas place on a coaxial cable, solder them at a distance of 5 to 10 cm from each other.
- Connect the cable to the phone or simply place the structure next to it.
