Android smartphone stopped catching the network, what to do. The Megafon operator does not catch the network: possible causes and solutions to the problem Why the phone does not see 3g
It is not always possible to use wired Internet, for example, in the country house, in country house, in a new office, and the mobile Internet works poorly or disappears altogether. In order not to burn nerve cells, trying to download a video or a heavy page for 10 minutes, you can buy an antenna amplifier. This article is devoted to one of the modern models - HiTE HYBRID, which helps to increase the speed of both 3G and 4G (LTE) Internet, does not require long settings (it took me no more than five minutes to connect) and is connected using one cable, through which both power and data transfer takes place.
The HiTE HYBRID antenna amplifies the signal using MIMO technology, which greatly increases the quality and stability of the Internet connection. The declared antenna gain for 4G is 2 × 16 dBi, for 3G - 2 × 13 dBi.
In addition, the Internet can be distributed through a router: HiTE HYBRID is compatible with all routers, and you can connect it to both a PC and a router.
We tested the HiTE HYBRID antenna for 4G signal amplification and got good results not only in Internet speed, but also in the convenience of installing and configuring the antenna.
By the way, since the 4G Internet is far from ubiquitous, in the absence of it, the antenna amplifies the 3G signal, and this deserves special mention.
Already now and for the future
Now all mobile operators are switching from 3G to the fourth generation Internet, but still 4G coverage is not everywhere.
It turns out that if you decide to amplify the 3G signal, you need to buy an antenna specifically for this reception frequency, and in a year or two, when the 4G coverage area reaches your area, you will have to buy a new one.
With HiTE HYBRID such troubles are excluded. It amplifies 3G and 4G signals and selects the best, so you don't have to worry about frequencies or buying new equipment.
Complete set and setup
In the box you will find the antenna itself and a neatly folded PoE adapter, Ethernet connection cable, power adapter and mount.
Antenna and accessories in the box
The HiTE HYBRID antenna has a durable and fully sealed metal and plastic housing with dimensions of 250 × 250 × 75 mm and a weight of 2 kg.
Antenna housing with waterproof connectors Of course, it is best if the antenna is installed outdoors, on the roof of a building or on a bracket outside the window. In this case, you can achieve maximum gain.
Working temperature range from -30 to + 50 °C. The manufacturer promises that work is possible even with more low temperatures if you do not turn off the power in winter. Mounting on a mast (or bracket) is included in the package.
A cable with a length of 30 m is suitable for the antenna. This is quite enough to stretch it from the house to the roof, but if you need more, you can extend it up to 100 m.
As we wrote above, this cable is used for both power and data transmission, which further simplifies installation - you do not have to buy any adapters and extension cords. The kit already has everything you need to operate the antenna.
Choosing a SIM
You will need a SIM card for the antenna. If your SIM card does not support 4G network at a frequency of 2500-2700, the antenna will work with a 3G network at a frequency of 1900-2200.
In general, the antenna will work with any Russian operator that provides mobile Internet using 3G or 4G technology. I tested the antenna with a Megaphone SIM card with 4G Internet.
SIM-card "Megaphone" 4G We insert the SIM card into a special slot and twist the waterproof cover. Sealed, so you don't have to worry about the safety of your SIM card.
We open the address indicated in the instructions on the PC and see the connection management interface.
Connection management interface Here is the connection status and statistics.
Statistics Antenna testing in the field
To test the speed of the antenna, I used the Speedtest.net service. To compare the speed, I took a modem from Megafon with me and tested it with the same 4G SIM card.
We decided to test the antenna in field conditions for which it is, in fact, intended. Since I have neither a dacha nor a country house, we just went to nature - to the forest not far from the city (about 12 km).
Location 1. Glade in the forest, 12 km from the city
6.21 Mbps - incoming speed, 1.21 Mbps - outgoing speed.
Modem: does not connect.
In the meadow We assembled it according to the instructions included in the kit: we connected the antenna to the POE adapter, the adapter to the laptop and connected it to the car network through the converter.
Antenna connection 
Connected and ready to go I must say right away that we tested in more than one place - somewhere the antenna worked better, somewhere worse. In the original location, where the modem completely refused to catch a 4G signal, the antenna gave out an incoming speed of 6.21 Mbps.
Location 2. On a hill, 12 km from the city
8.62 Mbps - incoming speed, 1.05 Mbps - outgoing speed.
Modem: does not connect.
It was the best fishing near the car, although due to the long cable we moved around the clearing, trying to catch the best signal. The most successful indicator in this area is 8.62 Mbps (stopped on a hill).
Speedtest results in the second location The next place was closer to the city, about 5 km away, in a field.
Location 3. Field, 5 km from the city
11.95 Mbps - incoming speed, 0.44 Mbps - outgoing speed.
Modem: 0.05 Mbps - incoming speed, 0.05 Mbps - outgoing speed.
We catch a signal in the field Here the modem from Megafon began to work. He gave out 0.05 Mbps (not to mention the fact that we barely waited for him to open the speed test at all).
With the antenna, the mobile Internet from Megafon soared to 11.95 Mbps. In principle, these were the best indicators that could be achieved.
General impression
If you use a 3G / 4G antenna outside the city, where the Internet often disappears altogether, the performance is very different from the same modem (which can be seen in the screenshots above).
In a forest clearing 12 km from the city, we got the speed with which you can use the Internet without the risk of breaking your computer from rabies.
In principle, if instead of a person who wanders around the field and forest glades, raising the antenna above his head, there was a master who would install the antenna on the roof of the cottage, the speed would be even more cheerful.
But, as I said above, to connect an antenna and get your legitimate 5–10 Mbps even on 3G, you don’t need any knowledge and skills.
So if you have been suffering from a slow mobile Internet(or lack of it), read the detailed specifications and order the antenna here↓
Hite Hybrid 3G/4G Antenna
P.S. HiTE also produces more powerful 4G LTE antennas, but we chose the HYBRID model for testing for its versatility and ease of setup.
Sometimes it happens to owners of smartphones on the Android operating system that the phone stops catching the network. To find out why the smartphone does not catch the network, first of all you need to understand whether there is a problem with the SIM card and the mobile operator or a problem in the device itself.
It often happens that the smartphone does not catch the network due to poor coverage of the cellular operator, or simply this frequency is not supported. For example, the 4G (LTE) signal catches mainly only in large cities and does not work outside the city at all. Also, the problem may be in a broken SIM card. In any case, you first need to check the network performance with different cellular operators. If not one of them did not work, then read below.
The phone bought in China does not catch the network.
What phone do you have? If you bought a phone from China and, for example, it does not catch 3G or 4G, then the problem is that the frequencies in China and Russia do not match, you cannot do anything here. That is why everyone is advised to buy phones from abroad with European firmware and with European communication standards, which, as you may know, are different from those used in Asian countries.
The smartphone on Android stopped catching the network after the firmware.
A very common problem. After installing custom firmware, such as CyanogenMod, OmniRom and others, the cellular network stops working. The whole problem is that the firmware contains settings for other frequencies, for example, as we wrote above - for Asian countries.
If you had signal reception before the firmware, then you need to select the frequency settings. To do this, go to the phone (dialer) and enter the code: *#*#4636#*#* , you will be taken to the engineering menu of the Android operating system. Go to the phone information, scroll to the middle, click on the button to turn off the radio, and then select the preferred network type GSM Auto, WCDMA preferred or WCDMA Only from the drop-down list.
GSM Auto - the phone itself will determine the best network coverage and select the required frequency, for example 2G/3G/4G.
WCDMA Preferred - will try to use 3G by default wherever possible.
WCDMA Only - always use 3G. By the way, this option does not work on some phones, for example Meizu.
If after selecting one of the three options, you still see the old option, don't panic. The desired option is selected and already saved.
Then press the button to turn on the radio again.
Reboot the device, after rebooting the smartphone, you should have a network again. If this does not happen - write in the comments, we will try to figure it out.
And finally, I would like to say that if the engineering menu did not help you and Android still does not catch the network with another SIM card, then the problem may be in the antenna or radio module. In this case, it is necessary to send the device for diagnostics to service center.
Each person at least once encountered a problem when the phone does not catch the network. Such a nuisance can manifest itself at the most inopportune moment. On the Web, users often discuss this topic. Surprisingly, this does not affect it at all. This can happen both with an expensive "iPhone" and with a cheap "Chinese".
However, if the phone does not catch the network, this does not mean that the device is broken. Before drawing conclusions, you need to check if there is a signal. The corresponding icon should be displayed on the main screen. It often happens that the user selects a network that is not supported by the operator. All the necessary information about this is in the gadget menu. And this is only one reason, but there are others that will be discussed in this article.
Does not catch or search for a network
Not the most pleasant reason, which can lead to the fact that the phone does not catch the network and stops looking for it, is a serious breakdown. This happens when an amplifier breaks down in the gadget that increases the power of the transmitter. To return the device to working condition, you will need to replace the components with new ones. It is not recommended to carry out these actions on your own, as it may be necessary to check other details, for example, the SIM connector, controller, antenna, and others. In order to be sure of the result, it is better to contact a qualified specialist.
The network suddenly disappeared
When the phone does not catch the network, it is worth looking for the reason in its internal details. If the signal suddenly disappeared, then this may indicate a breakdown of the radio path. This element is essential for the operation of the gadget. It is connected with a lot of details. It is impossible to check its performance at home, as well as independently make repairs. In order to be 100% sure that the problem is in the radio path, you will need a complete diagnosis of the device. Such services are provided by service centers or workshops specializing in phone repair.
The phone does not catch the network well
If the phone has a signal from a cellular operator, but it is either very weak, or disappears altogether, and then recovers on its own, then most likely the reason is in the antenna. This breakdown is by far the most common. Although the antenna is not visible externally, it still remains a rather fragile element. For example, if the phone is dropped, deformation may occur. Accordingly, it will lead to breakage. Repair consists in replacing the antenna. The work is simple and does not require large expenses from the owner.
Intermittent signal loss
Unstable signal, the phone does not catch the network? Why does this happen even with new devices? In most cases, the reason is quite banal - an unscrupulous attitude with the device. Not every user is aware that even a very small drop of water, getting inside the device, can lead to unstable operation of the phone. The consequences are unpredictable.
In this case, the owner is advised to take the gadget to a service center, where specialists will make a diagnosis. This will determine the exact reason why the loss of signal occurs. If the penetration of moisture into the device is confirmed, the master will clean all contacts to prevent corrosion.
It is important to remember that if you do not clean the device in a timely manner, then soon malfunctions will appear much more often, affecting other elements.
Cellular network missing
What to do if the phone does not catch the network? No signal icon is displayed on the device screen. The machine does not attempt to connect to the network automatically. Every second owner of modern smartphones faced such a problem. The most common cause is a software glitch. If rebooting the device did not fix the problem, then you will have to take drastic measures, that is, reflash the system.
In order to be sure of a positive result, it is recommended to consult a specialist. But at present, firmware for all brands of phones can be found on the Internet, so advanced users do these manipulations on their own. Each person, having decided on this step, performs actions at his own peril and risk. After flashing the system, the gadget is automatically removed from the warranty, so if something goes wrong, even experienced craftsmen will not save the phone.
Phones from China
With the advent of access to the World Wide Web, every resident of Russia has the opportunity to buy cheap phones through Chinese online stores. It is worth noting that the difference in price is significantly different, but there are more risks. By purchasing a phone at an authorized point of sale, the buyer can inspect the gadget, try it in operation, and also receive a guarantee that provides free maintenance for a certain period.
And what do shops in China offer? You can judge the purchased phone only by the picture. It is not always possible to find out the exact characteristics, so some buyers are faced with such a problem as the phone does not support Russian standard cellular communication. In this case, the user can no longer do anything.
Problems with mobile signal reception are common. In this article, we will look at the main reasons why a phone can “lose” the network, causing inconvenience to its owner.
Since today MTS is three technologies at once (2G / 3G / 4G), and they all operate at different frequencies and according to different principles, there can be a number of reasons for interruptions in communication.
Why is MTS not catching the network today?
If the signal has always been stable, but suddenly there are interruptions, it can be assumed that technical work on the network. The operator regularly upgrades the network, therefore, on the scale of Russia, several "white spots" appear daily on the coverage map.
In addition, common causes of no or poor signal quality are:
- Bad network architecture. If the operator has saved on base stations, or the terrain has difficult terrain (you are in a lowland), there is a high probability of a lack of signal.
- Obstacles in the signal path. For example, the signal often disappears inside monolithic houses, since the reinforcement in concrete partially shields the radio signal. Therefore, sometimes it is enough to come closer to the window.
- Infrastructure damage. If the base station fails or the cable infrastructure is damaged, the signal may also disappear.
Why the phone can not catch the Internet from MTS?
Quite often there is a situation when the MTS voice communication is functioning normally, and the data transmission service is unavailable. This may be for the following reasons:
- There are flaws in the network architecture, due to which the data transfer service de facto cannot work normally.
- The network is overloaded and cannot withstand the influx of subscribers. Sometimes it helps to simply restart the communication module (turn on and off the "airplane" mode on the smartphone).
- 3G/4G networks are simply not available. accustomed to high speed the subscriber may decide that the Internet does not work at all when he has to wait for a response for 20-30 seconds.
- The account has run out of money or service packages have been exhausted.
Why does MTS not catch the 3G network?
Problems with access to the 3G network are a common problem among MTS subscribers. The most common reasons:
- Lack of "carpet" covering of the third generation. Unlike GSM, 3G is available only in cities, on major highways and in some small towns.
- Bad radio planning. Often a situation arises when the phone displays the 3G or HSPA icon, but in fact the network does not work. This means that there is no real coverage in your location.
- Sometimes the signal is so low that the waiting time for a response increases significantly. And if the data transfer rate itself is satisfactory, then the response time can reach several tens of seconds.
Why does MTS not catch the 4G network?
4G coverage of MTS has even more "white holes" than 3G. Even across the territory of Moscow, there are many zones where there is no reliable signal, not to mention the regions of Russia. Therefore, the most likely reason for the lack of a 4G signal is the banal lack of coverage.
In addition, the 4G network does not have the best indoor coverage in Moscow, therefore, in many residential and commercial buildings, the connection may be lost.
Why does the MTS sim card not catch the network?
In conclusion, we note that sometimes the problem is in hardware elements: a SIM card or a phone. You can verify that there are hardware problems by trying to put another SIM card into your phone, or by putting your SIM card into another phone.
