Reasons why the phone does not pick up the network Megafon, Beeline, MTS, Tele2

Recently, more and more subscribers are faced with the problem of poor communication quality or dropped calls. The reason for this is overload of cell phone towers. Base stations, despite even the most modern equipment, do not always cope with the mass of active subscribers.

If the phone stops receiving the network, users begin to think about changing their mobile device or provider. Let's figure out whether it's worth immediately deciding to take such radical measures, and what opportunities there are to correct the situation on your own.

Poor cellular communication can be due to several reasons:

• An unstable signal coming from the tower. This happens when the repeater is located at a great distance from the user’s mobile device. As a result, there is no cellular network signal at all.
• Features of the local terrain;
• The presence of objects that screen the incoming signal - these are either dense buildings or dense forests;

One or more of these factors affect the mobile communications of 70% of users in Russia and make them think about how to try to improve a weak cellular signal themselves. If there is no mobile network signal on your phone, the solution should be comprehensive:

• Find out the prospects for the construction of new repeater towers from your provider. Each operator posts a map of existing and under construction towers on its website. It is possible to immediately reconnect to a provider whose repeater is located at a minimum distance from you;
• If possible, get rid of objects that block the passage of radio waves or use gadgets in places with the clearest reception (on the street, near a window or on some hill);
• Refuse to talk on the speakerphone, since usually the device lies on the surface, and its receiving antenna is located horizontally and does not provide optimal reception of radio waves;
• Make sure that the battery does not discharge. Low battery is one of the causes of communication problems, as it does not provide the necessary signal clarity;
• Install a cellular repeater.

Basic diagnostics

Let's first try to rule out the problem on the telecom operator's side. If the SIM card is detected on your device, but there is an inscription: “Emergency calls only,” go to the network settings.

You need to find the menu “Mobile network settings” and “Network operators”.

Next, go to “Search for networks.” Let's try to find available operators manually.

When the phone's modem is working, it will search for available networks of all telecom operators.

Of course, problems on the telecom operator’s side cannot be ruled out. There may be problems with towers or technical glitches.

If yours is not among the operators found, try the following:

1. Reboot your phone;
2. Remove and reinsert the SIM card;
3. If possible, try installing the SIM card in a different slot;
4. Try installing a SIM card from a different carrier.

And yet, it also happens that the SIM card simply becomes demagnetized and stops working. This applies to old cards. Over time, any SIM card fails.

Communication module failure

As a result of mechanical impact on the smartphone body, the modules responsible for receiving the network signal can be damaged.

• Disabling the SIM slot cable or antenna is a fairly common cause of problems. To fix it, it is best to contact a specialist, since any tampering with the device’s body will void the warranty.
• Replacement of the antenna with a low-quality Chinese analogue during repairs. Some “masters”, hoping to save money, use the cheapest modules. This leads to deterioration in the quality of signal reception and rapid failure of the board.

Error during registration

If the phone cannot find the network or cannot register with the operator, then there may be a problem with the antenna and coaxial cable.

The coaxial cable may move away from the board connector if it hits the surface of the smartphone. Without this cable, the connection will be unstable. Therefore, the phone cannot register with the network.

And both the antenna itself and the connectors for its connection may be damaged.

Such problems can only be diagnosed after opening the device. But do not rush to do this if you have not tried another SIM card.

Reset

After incorrectly flashing the device, the network may periodically disappear or work intermittently. In this case, you need to carry out a full diagnostic of the device and return the factory firmware.

In “especially advanced” cases, you cannot do without a complete reset of the settings.

1. Go to your smartphone settings.
2. Open the “Backup and reset” tab, tap “Reset settings”.

Important! Do not check the box next to “Delete all user data and clear internal memory.”

1. Confirm the reset. The procedure may take from 15 to 30 seconds, depending on the load on the phone's processor.

Moisture ingress

And it’s not uncommon for the lack of communication to be caused by water getting on the board. Even if you have dried your phone well, there may still be water left under the chips. Contacts oxidize and rot. Sometimes even one oxidized SMD capacitor near the antenna is enough for your phone to stop receiving the signal from the telecom operator.

For example, the new iPhones have modem and communication chips located directly under the SIM connector.

And in the old ones they are located nearby, but nevertheless, the risk of moisture getting through the connector onto the microcircuits is quite high.

Without soldering and cleaning the microcircuits with special liquids, the connection cannot be restored using software methods.

What does the signal level depend on?

When installing a mobile network, operators take into account several factors that affect the level of reception.

Distance from transmitter

High-quality antennas easily pick up a signal at a distance of 10-15 kilometers from the tower. But this is an ideal indicator. Typically, the reliable reception distance for an average smartphone is only 5-10 km and is highly dependent on the terrain.

Natural obstacles, hills and wooded areas

Slopes, valleys, hills and other terrain features make reception inaccessible, as they are impenetrable to radio signals. Communication is especially bad if you are in a lowland and the tower is located on a flat area behind a hill.

Atmospheric phenomena and weather

When there is a thunderstorm front or atmospheric storms, good communication cannot be obtained even near the transmitter. If you are 3-5 km away from it, there will be only one or two sticks on the screen.

Amplifier model and built-in antenna power

This factor depends on the manufacturer of the device and the quality of the components. Some Samsung and Nokia models have particularly high performance, but some Chinese smartphone leaders also don’t skimp on good antennas.

Dead spots

Certain areas are simply not covered by specific service providers. Thesis is called blind spots or dead zones. If you find yourself in such a place, the best thing you can do is quickly leave it.

SIM card is not detected

This is also a fairly common problem when the SIM card is not detected and therefore there is no connection.

There can be four main reasons:

1. Damage to SIM connector contacts;
2. SIM card demagnetization;
3. Incorrect card installation;
4. Moisture ingress.

We have previously discussed cases of SIM card demagnetization and moisture penetration. Now let's look at cases with damaged contacts and incorrect SIM installation.

Main reasons

All reasons can be divided into several categories: hardware and software.

Hardware

• Failure of the SIM card slot. A malfunction can happen for many reasons - dropping the phone, carelessly connecting the SIM card, or moisture getting into the case.
• Damage to the SIM card itself is a fairly common cause. This may occur if the SIM card is constantly moved from one device to another or is handled carelessly.
• Disconnection of the antenna loop or breakdown of other modules associated with connection to the operator. In this case, the device stops picking up cell towers and the network constantly disappears.

Software

• Malfunctions in the operating system that caused the communication module to turn off.
• Incorrect cellular settings in the smartphone settings.
• Infection of the device with malicious software that can affect signal reception.

Can a phone break after a software update?

Remember when you updated your phone software and whether you used the network after that. If the update was on the same day, and you did not pick up the phone after that, such coincidences cannot be accidental. Most likely, something went wrong during the update or the update itself had errors.

New firmware is good for everyone, but it can damage the phone.

In this case, you need to go through the methods for solving the problem indicated above, and if all else fails, reset the phone to factory settings, having first created a backup copy of the data. If you have difficulties with this, it is better to contact a service center or at least friends who understand.

Phones from the Middle Kingdom

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 also more risks. By purchasing a phone from an authorized sales point, the buyer can inspect the gadget, try it in operation, and also receive a guarantee that provides free service for a certain period.

What do shops in the Middle Kingdom offer? You can judge the phone you are purchasing only by the picture. It is not always possible to find out the exact characteristics, so some buyers are faced with the problem that the phone does not support the Russian cellular communication standard. In this case, the user will no longer be able to do anything.

Beeline number holders, as a rule, do not complain about the quality of communication: this operator has traditionally excellent quality. But no one is immune from accidents, and one fine day you may discover that your Beeline phone or tablet does not pick up the network.

Why did this happen? Let's figure it out.

Using a backup network

This method is suitable for cases when conventional connection methods are not available. For example, the user is disconnected for non-payment, there is no power, or there is a breakdown or accident.

To create a backup connection, you need:

• 3G modem;
• router.

3G allows you to connect to a cellular operator. The router can amplify the signal and distribute it to devices. This option will work anywhere where there is an electrical power source.

Even if there is no outlet nearby, the user will have about 20 hours. With a 3G connection, the speed will be up to 42 Mbit/s. With 4G you can expect speeds of up to 150 Mbps. Up to a dozen people will be able to use the network.

No connection Megafon today

A complete lack of communication may indicate possible problems:

1. Being out of reach. Problems often arise when traveling in another region. To avoid them, it is recommended to find out information about the availability of coverage in advance.
2. Internal breakdown of the phone. As a rule, this concerns damage to the SIM card slot, modem or antenna.
3. Damage to access points. In such cases, the tower providing communications in a specific area is probably not working. You can check this information by calling or sending an online request to the customer support center.

You should also find out information about possible breakdowns or preventative maintenance from the customer support center. However, in such cases, you should be prepared for the fact that network congestion and busyness will not allow you to quickly find out what is wrong with Megafon communications today.

SMS does not work on Megafon: what to do?

First of all, you need to check the balance status or the presence of SMS in the purchased package of messages (if any). If in both cases there are no resources, the message will not be sent. To resume their use, you will need to top up your account or purchase an additional package of services.

Other possible reasons include:

• Incorrect entry of SMS center number. It is necessary to check the accuracy of the recorded number and the presence of +7 or 8 at the beginning (the number must be 11 digits).
• There is a ban on sending instant messages. To disable the service, you need to dial *330*111#.
• Phone limitations or problems. In this case, you should check the SIM card on another phone, or reboot yours.

If Megafon still doesn’t work today in terms of sending SMS, it is recommended to contact support service. It is available via hotline number, technical support, as well as online chat on the company website.

Why is cellular communication unstable?

The fact is that a mobile communication signal is a radio frequency electromagnetic wave transmitted in encoded form between two base stations. Even with a large coverage area and powerful repeaters, this wave is not able to penetrate barriers.

Such barriers include the walls of buildings made of solid building materials, for example, cement, concrete, and a variety of wood. And what can we say then about those areas where poor Beeline or MTS communication is due to incomplete coverage and difficult terrain!

If mobile communications “show signs of life” in such buildings, it is only due to the penetration of the signal through windows and doors. Thus, you can criticize the poor connection of a megaphone or another operator as much as you like, but the company is not to blame for such instability of reception.

Modern cellular companies are actively increasing the capacity of their networks, expanding their coverage area, and increasing the list of services provided, but they cannot eliminate the causes of communication instability. Physics dictates its own laws.

Why is the internet bad?

Normal internet at the dacha is needed for uninterrupted operation of programs, viewing various content, performing banking transactions and other actions. Not everyone takes the time to figure out why the Internet connection is poor. Therefore, they waste a lot of time waiting for content to download to their laptop, PC or phone.

Among the causes of the problem:

• Browser crashes;
• viruses in the device;
• bad connection;
• many connected users.

Often the browser begins to lag when it has not been reinstalled on the computer for a long time. Some people have been using the old version for years. Sometimes the user may blame the operating system and gets to the point where they have to reinstall it.

After reinstallation, a new version of the browser is downloaded and the problem is solved. However, the reason remains unclear. To check the status of the browser, you can reinstall it and see how the pages load.

Viruses are often the cause of the problem. In this case, unknown icons appear on the program taskbar. Unknown pages may also open on their own.

To solve the problem, you need to pay attention to the notifications of your antivirus program. If it detects any malicious components, you must follow the suggested recommendations. For those who do not have an antivirus, it is advisable to download it and scan your computer. You can also use special utilities.

Some users place routers far from the computer or, trying to hide the cable indoors, pinch it. Gradually the wire becomes deformed and causes a weak signal. If the network begins to slow down due to cable deformation, just contact your provider and replace the cable. You can also place the router closer to your laptop or PC, which will improve its performance.

Every year the quality of content improves. Accordingly, the volume of downloaded files increases. Online games take on a lot. If at the same time several people in the family use the Internet source at once, the download speed is significantly reduced.

The phone has poor network reception

If the phone has a signal from a cellular operator, but it is very weak, then disappears completely, and then recovers on its own, then most likely the reason is in the antenna. This breakdown is considered the most common today. The antenna, although not visible from the outside, still remains a rather fragile element. For example, if the phone is dropped, deformation may occur. Accordingly, this will lead to breakdown. The repair consists of replacing the antenna. The work is simple and will not require large expenses from the owner.

SIM card contamination

Communication may deteriorate due to problems with the SIM card: if you often move it from one slot to another or put it in another phone, corrosion will appear on it over time. You only need to move the card with clean hands, since corrosion occurs when you touch the contact pad with greasy or dirty fingers.

Dirt and oxidation can be cleaned with a stationery eraser, and contacts can be wiped with alcohol.

Why are there network problems?

Are you going to find out why your phone has poor network reception? Consider all possible reasons.

Remoteness of the operator's base station

Most often, problems concern people who use transport (for example, a personal car). This occurs due to the fact that the subscriber moves away from the operator’s station and leaves the network coverage area. Improving the quality of communication and comfortable use of the phone require the purchase of a repeater - a special device that amplifies the signal.

Natural Obstacles

Natural barriers can interfere with the normal propagation of the signal: mountains, hills, forests (especially in spring and summer, when the trees are covered with leaves). It is possible to partially correct the situation at the dacha by pruning the branches, but this procedure is expensive and requires obtaining the appropriate permit. The simplest, most effective option is to buy a cellular communication booster kit, which allows you to use your phone regardless of natural conditions or distance to the city.

Use of muffler building materials

Brick walls, double-glazed windows, and aluminized insulation interfere with signal transmission. Most often, the problem affects residents of areas where there are many high-rise buildings (especially owners of apartments on the lower floors).

Design features of a mobile phone

Small antennas have low power and therefore are not able to guarantee uninterrupted communication everywhere. When leaving the city or moving into brick buildings, the device stops working fully, and the signal quality inevitably decreases. Owners of phones with weak emitters are recommended to use amplification kits that include a repeater, indoor and outdoor antennas.

Network congestion

Large cities are characterized by the problem of network congestion, when hundreds or thousands of users use one repeater tower. The repeater's task is to collect information about several communication towers, connecting the subscriber to the least loaded one. If the power of the phone's antenna does not allow you to connect to a distant station (this happens quite often), conversations are interrupted and the Internet disappears.

Wi-Fi connection

Reconnecting the network

As with cellular communications, Wi-Fi needs to be reset somehow. If airplane mode helped before, now you just need to reconnect the network. You may need to “forget” it and enter the password again.

Checking the router settings

Often poor working Wi-Fi is a direct consequence of incorrect operation of the router. It is worth knowing that cheap routers may have limitations in speed and the number of connected devices. Even despite the numbers stated by the manufacturer. Therefore, connect to Wi-Fi and from the same device type the following line in the browser: 192.168.1.1 .

Next you will be asked to enter your username and password. By default, this is admin-admin , but not always, it is better to check with your provider. Then fully study the presented menu. Maybe a cunning neighbor is stealing your network, and because of this, everything is working poorly for you.

Changing the frequency from 2.4 GHz to 5 GHz

Nowadays, most routers operate in two bands: 2.4 and 5 GHz. This allows you to relieve the channel and have a higher transmission speed . If your router supports a 5.5 GHz connection, then it is best to do this through it. Compared to 2.4 GHz, it has a shorter range, but is faster.

These are the recommendations that can be made in terms of dealing with a slow network. How do you deal with poor communication on a smartphone?
