The phone does not see 3g. Why is the phone not picking up the network? Causes. The phone bought in China does not catch the network

Why the phone does not catch 3G?

If any electronic device stops working, then there are two reasons for this

1. somewhere there is no necessary contact;
2. somewhere extra contact.

This is under constant external conditions. Maybe a house was built between you and the base station?

Not every phone has settings for network detection, usually the network is detected automatically. In the settings, you need to look for the definition of the network (perhaps the name will be different), rearrange the checkbox from automatic to 3G, restart the device and everything should work out. But there are times when the 3G network coverage area changes and it simply doesn’t exist exactly where you are, so the device switches to another network that is available and works in it. It happens that the device is buggy (most often this happens with a usb modem), there may not be a network even for a day, and in order to understand the reason, you need to call the operator, who in turn will look at your statistics and determine the problem.

First you need to check whether 3g is connected or not. You can try restarting your phone, or see if mobile data is turned on.

You need to check the network settings, and switch to another network, maybe 3g will be caught.

Maybe the problem could be for example because of the weather. Close the tower due to rain.

There may also be a bad signal or deterioration. Due to a malfunction of the tower or due to the fact that some object interferes with the signal. It may have been built between the tower and the house.

You need to go to another part of the house, the apartment may be good for catching 3g there.

If all this does not help, then you need to take the phone in for repair.

There can be many versions, one of the common reasons is that you do not have 3G support on your phone at all, or it is not enabled in the network settings. Also, in some phones, 3G is indicated by the letter Hquot ;, above the antenna mark.

If your phone stopped catching 3G, then this only means that your phone was damaged and stopped catching the network, or the free 3G access point simply closed, or simply ceased to be visible to you, this often happens.

Option 1 - the phone does not have a 3G module. The solution is to buy a 3G router to distribute the Internet via Wi-Fi:

Option 2 - no 3G coverage. Nothing will help here.

The phone may not catch 3G for several reasons.

The most banal of them is a too weak signal (for example, you are in a forest or in a field) and there are no towers nearby, so the phone does not pick up.

There may also be problems with the device itself, perhaps this is a glitch or some other malfunction.

if the icon is on, it does not mean that there is 3g.

After the service is disabled by the operator, for example, in the absence of funds, the phone must be restarted.

And be sure to check the Internet and MMS settings, they can fly off after installing other sims

Usually these two reasons are to blame.

And do not forget to turn on data transfer: D

The 3g network may not catch for various reasons.

For example, because the phone is currently far from the tower of the mobile operator and therefore there is no connection and there is also no this network.

In the phone settings, though, not all have network settings in which you can select a network, usually 3g or other networks. If the phone has such settings, you need to rearrange it from the network that is on the 3g network and then it will be caught.

Perhaps the network in the phone is turned off or other settings are due to which 3g is not caught.

Or maybe it's something with the phone and it broke down due to which there are communication failures.

You need to check all this to catch the net.

3G may not catch for several reasons. The first reason may depend on the fact that 3G coverage is not available in your region or it simply does not exist. To do this, call the operator and check if there is 3G in this region.

The second reason may be due to the fact that your phone does not support 3G, or your phone is faulty and needs repair or phone firmware.

Buy an amplifier for a modem, which is used to improve the quality of cellular communication with insufficient mobile Internet speed, this is a 3G 4G amplifier. This is a turnkey solution for providing a stable and fast Internet. These devices are compatible with various USB modems. They differ in the characteristics of the directional antenna, which affects the improvement of the Internet signal and the increase in the speed of the modem. You can see the entire list of Internet signal amplifiers lt;a href=http://select.meldana.com/catalog/repeaters/complect-3g-4g>herelt;/a>

It happens that the phone does not catch 3G after it has successfully caught it. And there is not only one reason for this. Firstly, perhaps your settings have simply gone wrong, set the 3G network in the settings (but not automatic network search) and restart your mobile device.

Also, the reason may be due to the fact that access to the network or free access was simply closed in this area. Or maybe your phone is buggy. For the last two points, you need to contact your operator so that he will answer for sure.

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 contact specialists. 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 from 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 the Russian cellular standard. In this case, the user can no longer do anything.

Good evening!

Thanks again everyone. who took part in the answers to the questions I posed. As promised, I will describe the results of the raised problem ...

1. The trip to the SC ended with nothing. The device was sent to the Kyiv SC "Lenovo", where it was kept for 10 days and returned unopened with a summary of "no defects found."

2. I had nothing to lose and I undertook to torment the poor phone. Since I had CM 13 installed (and on the forums people wrote that the reception on Cyan is worse than on the drain) I decided to roll back to S246_ROW_Deodex . Moreover, recently I noticed such a thing - when loading Cyan, before the logo with horns appeared, the screen blinked in blue, and only then the logo appeared and the download was in progress. This moment with a blinking blue strained me, because I heard that this happens when the "motherboard" dies.

3. I have TWRP 3.0.2 , an excellent recovery for me, and even with the support of the Russian language. I undertook to do a complete wipe of the system .... And when deleting data, I started to see a message about the impossibility to mount the partition Persist. By talking on the w3bsit3-dns.com forum, I found that this section is responsible for Wi-Fi and all sorts of other sensors ...

4. Okay, no Persist so no. I'm loading S246_ROW_Deodex... the phone is loading, while there is no Wi-Fi, but there is a STABLE reception on the phone's SIM cards - call wherever you want from the apartment !!! I don't know why, but it happened.

5. On the forum, I ask the guys to help with the Persist backup for the Chinese made through FlashFire (a cool thing, I must say!). I find my FIRST backup made on TWRP from SevenMax 2.8.6. First I flash S246_ROW_Deodex, then Persist - there is no result ... When I try to make a call, the message "Turn off the Flight mode first" pops up, despite the fact that the mode is disabled, of course.

6. By searching for similar topics on the net, I find that yes ... in some magical way, the Flight mode is associated with the reception of SIM signals. By experimenting with turning the "Flight" on and off and rebooting, I'm convinced that for 5-8 times the signal of the networks MAY appear.

7. I reflash the phone again on S246, but only a little different, on S246_CN_TWRP from respected destroyer71 from the w3bsit3-dns.com forum. During the initial boot of the system, the "Mobile network activation" item appears where the phone tried for 8 minutes (I did not have enough patience) to connect my SIM cards.

6. And here, gentlemen, is the result: when the shell is loaded, there is no network reception signal, but IT APPEARS in the 2-3rd minute of operation. I rebooted three times - at first there is no network signal, but a little later it appears. Sluggish, unstable BUT IS!

My conclusion is that the "mother" is dying, slowly but steadily. I will sell the phone, alas ...

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 interruptions suddenly appeared, it can be assumed that technical work is being done 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. A subscriber accustomed to high speed may decide that the Internet does not work at all when you have 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.

It is not always possible to use wired Internet, for example, in a country house, in a country house, in a new office, and mobile Internet does not work well 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.

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 it is possible to work at lower temperatures if the power is not turned off 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.

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.

Here is the connection status and 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 the field, 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.

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.

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).

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.

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 slow mobile Internet (or lack of it) for a long time, you can read detailed specifications and order an 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.
