TOP 5 Reasons Why Mobile Internet Doesn't Work

If Android does not connect to the Internet via the mobile network, then the cause of the problem should be looked for in the system settings. In rare cases, the mobile Internet does not work due to failures on the side of the telecom operator; usually, the user can fix the error on his own.

This article is suitable for all brands that produce phones on Android 9/8/7/6: Samsung, HTC, Lenovo, LG, Sony, ZTE, Huawei, Meizu, Fly, Alcatel, Xiaomi, Nokia and others. We are not responsible for your actions.

Reasons why the phone stopped receiving the network

The problem when the phone stops receiving communication may be caused by a malfunction of the SIM card or the smartphone itself. In the first case, you can solve the problem yourself or by contacting specialists from your GSM mobile operator. In the second case, the assistance of qualified technical specialists may be required.

When faced with the fact that your phone has stopped receiving 3G, you first need to make sure that you are in the coverage area. As a rule, mobile communications work much worse outside the city or in underground premises. If you are within the city and in the service area, then pay attention to exactly how the phone works. The reason to contact the operator is when the phone:

does not search for a 4G network,
4G signal is poor,
can't find 4G network,
Loses 4G signal.

Just in case, you need to check whether your neighbor’s or friend’s phone has a signal. If the problem is only in your smartphone, then you should check the SIM card and diagnose the device.

Often the reason why the phone stops receiving the network is moisture. To avoid corrosion of parts, only a service center specialist should repair the fault.

Setting up your phone manually

So, phones predominantly have only 3G family protocols, with a transition to 2G when communications with a higher bitrate fail. This means that access to the Internet is always carried out using third-generation protocols, if conditions allow. 4G can sometimes come into play if supported by the cellular operator. For example, on the MTS website, according to the classification, the intermediate generation of specification 9 is advertised, unless the moderators and designers made mistakes.

The settings are different and depend on the mobile operator, and the installation method is different for each device model. Therefore, to find out how to connect 3G on your phone, it is better to contact the operator directly. Information about connection can be found at the following links:

MTS – https://www.mts.ru/mobil_inet_and_tv/help/settings/settings_phone/inet_settings/
Beeline – https://moskva.beeline.ru/customers/help/mobile/mobilnyy-internet/nastroika-telefona/
Megafon – https://moscow.megafon.ru/help/faq/#nastroit-internet

If it is impossible to go to the information site of the mobile operator and rewrite the network access settings, then you can try the following data:

Name: Beeline
Username: beeline
APN: internet.beeline.ru
Password: beeline
APN type: default
APN protocol: IPv4
Authentication type: PAP

Name: MTS
Username: mts
APN: internet.mts.ru
Password: mts
MMS protocol: WAP 2.0
MSS: 250
MNC: 01
APN type: default

Name: megafon
Username: gdata
APN: internet
Password: gdata
APN type: default
MCC: 250
MNC: 02

Let's look at the setup procedure step by step using the Nokia Lumia 520 as an example.

Go to the menu and select SETTINGS.
In SETTINGS we find ACCESS POINT.
Click + (add).
In the window you need to fill in: name, username, APN, password.

As soon as access is available, 3G will automatically be picked up. We continue to configure:

Go to the SETTINGS menu.
Click on the item CELLULAR COMMUNICATIONS + SIM.
Set the data transfer lever to the OFF position.
Below, under the inscription “fastest connection”, set the 3G mode.
Click on SIM CARD SETTINGS.
In the menu, set SEARCH FOR NETWORKS.
After a few seconds of searching, select the operator you need.
Go back and set the data transfer lever to the ON position.

The 3G connection icon should appear on the display, it can be: 3G, H+, H, triangle. The absence of an icon indicates that an error has crept into the settings or you are outside the 3G network area. You can try restarting your mobile phone.

If you are using a device with two SIM cards, please note that only one of the two cards will work in 3G. As a rule, the first slot is provided for 3G cards. Some phones indicate the supported connection type next to the slot.

Usually, when the 3G signal is lost, the device automatically switches to 2G mode and back. But in some cases, phones do this incorrectly and may not detect the network at all. In this case, make sure you have automatic network search set. If not, then turn it on.

What should you do if your phone stops receiving the network due to a SIM card malfunction?

As with any other device, malfunctions may also occur in the operation of the SIM card. If it has been collecting dust in the closet for a long time or, conversely, has often been moved from phone to phone, then this may be the reason why the phone has stopped receiving communications. Solving the problem is quite easy - you need to install the SIM on another smartphone. If it turns out to be blocked or damaged, you need to contact your GSM operator. Specialists will conduct diagnostics to find out why the phone stopped receiving 4g, and then they will replace the SIM card.

What to do if your phone stops receiving the network due to a hardware failure?

If the SIM card is working properly, the cause of the problem may lie in the Android Phone itself. In some situations, the problem can be resolved by correcting your network settings. To do this you need to do the following:

go to the “Settings” menu,
select automatic search mode;
select your network.

If the device does not pick up the signal automatically, you need to try to find it manually.

In 90% of cases, the reason why the phone stopped picking up is a malfunction of the antenna, which can be caused by mechanical damage. Only repairs will help correct the situation.

The help of specialists is also needed if the phone stops receiving communication due to a breakdown of the radio contact and the sensor’s power amplifier. In these cases, the network completely disappears on the smartphone or it does not look for it at all.

What to do if the phone stops receiving the network after flashing?

Many users prefer to flash their Android phone themselves, not knowing what problems this can lead to. If your phone stops receiving 4g immediately after flashing the firmware, you need to do the following:

type *#*#4636#*#* on the input panel;
in the engineering menu that opens, go to the “Phone information” section;
Scroll to “Turn off radio”;
select the network standard.

There are three network standards:

GSM Auto for independent determination and selection of the desired frequency;
WCDMA Preferred to select 3G by default;
WCDMA Only to select only 3G standard.

After selecting the network, you need to activate and restart the phone again.

If none of these steps help and the problem is not solved, you need to contact the service center specialists.

In this article, we looked at what to do if the phone stops receiving the network, and why such a problem occurs. To be able to access the Internet or make calls without thinking about why 4G is not working, you need to use your smartphone more carefully and carefully monitor its condition.

The article will tell you why the 3G Internet of different operators is poorly received and how to make your own antenna for a 3G modem.

Navigation

Often, 3G mobile Internet users complain that the connection is poor or non-existent. This problem happens when using almost any mobile operator, so it can be considered universal.

In today's review we will discuss the reasons why 3G Internet does not catch or does not catch well on Beeline

", "
Megafone
", "
Tele2
" and "
MTS
". We will also discuss how to boost the signal and make an antenna for 3G Internet with your own hands at home.

Diagnostics of a modem located in the list of devices

You have polled the modem, it answers correctly, which means we continue to diagnose it. We check the network and its settings.

Start - Control Panel - Network Connection. Or use the “Windows + R” keys, and in the window that opens, write “ncpa.cpl” and click “OK”. In any case, the network connections folder will open.
In this folder we find the connection we need, hover the cursor over it and right-click. Select “Properties” and check in the “General” tab whether the connection is connected to the modem.
After that, open the “Network” tab. We find in it “Internet Protocol (TCP/IP)”. Let's check its properties. There should be no entries there.
After checking, making sure that everything is fine, close all windows and try to connect.

Reasons why 3G Internet does not work

There may be several reasons why 3G Internet reception is poor for various mobile operators. All of them are very common, among them there are both common to all mobile operators and their own specific ones. Let's discuss this.

The mobile operator has not expanded its network everywhere

The fact is that for the mobile Internet, as for radio or TV, appropriate stations are needed that transmit the signal to the antennas of the phones. Such stations should be placed wherever people most often appear, especially in places of permanent residence.

Among all mobile operators, only Megafon

" can boast of efforts to install its stations in a variety of places, including sparsely populated villages.
Other operators, as a rule, establish their networks in metropolitan areas, cities, and close to the countryside. “ Tele2
,” for example, is generally intended for use in certain regions of the country.

In this regard, the mobile Internet will not always and everywhere work stably, depending on the operator you use.

Standard reasons

There is no money in the account
. It is not difficult to guess that if you do not have enough funds in your account to pay for 3G Internet, you will not be able to use it.

No money in account

You are out of network coverage
. Also a well-known reason. If you are in a basement, in an elevator or somewhere else (we described this problem above), then the connection will be poor or completely absent.

You are out of network coverage

The phone is not configured correctly
.
If you have not activated the “ Mobile data transfer
” option, then you must definitely enable it.
This item is in its place in different models of gadgets, but we will give an example with a regular smartphone. In your smartphone settings, go to “ More-Mobile network
” and activate the “
Mobile data transfer
” option.

In the smartphone settings, go to “More-Mobile network” and activate the “Mobile data transfer” option

. Sometimes it happens that you got out of the metro (where there was a bad connection), and there is still no connection to the mobile Internet. In this case, you need to turn off the phone and turn it on again. Everything should work.

How to enable 3G on Android

In the Android OS, the button to turn on the mobile Internet is located on the quick access panel, which appears when the user pulls the “curtain” from the top of the screen down. Just click the “ Mobile Internet”

" to enable or disable 3G on your phone. Depending on the type of network selected, the corresponding icon will appear in the status bar:

"E" for 2G

"H+" or "3G" for 3G

"4G" for 4G

Important to know: Connecting to new generation mobile networks can greatly reduce the battery life of your smartphone. Therefore, if it is important for you to save battery power, you should not turn on 4G, but it is better to turn off mobile Internet altogether when it is not needed.

Every person has at least once encountered a problem when the phone does not connect to the network. Such a nuisance can appear at the most inopportune moment. Users often discuss this topic on the Internet. Surprisingly, this has no effect at all. This can happen with both an expensive iPhone and a cheap Chinese one.

However, if the phone does not connect to the network, this does not mean that the device is broken. Before drawing conclusions, you need to check whether there is a signal. The corresponding icon should be displayed on the main screen. It often happens that the user chooses 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.

How to measure Internet speed on your phone

It is recommended to use the SpeedTest program on mobile devices. Before starting the analysis, restart the gadget, install the application and disable the activation of other programs, close all browser bookmarks.

When evaluating the test, it is important to look at the download speed, since this is indicated by mobile operators in the charging conditions. The upload rate in this case is less important and 0.5 Mbit/s is sufficient for the Internet. Normal network use will be noticeable if the speed difference is 0-1 Mbit/sec and 1-10 Mbit/sec; anything higher is only noticeable when downloading large files or watching videos with a large extension.

For a stable Internet, a value of 5-10 Mbit/sec will be sufficient, and it makes sense to use expensive tariffs only if you need to frequently download large data.

It is recommended to perform testing several times at once to get the most accurate and closest to the real result. If the speed is significantly lower than that specified by the mobile operator, within the tariff limits, or there is instability of access, then you need to use other methods given in the article.

Does not catch or search the network

A serious breakdown is not the most pleasant reason that can lead to the fact that the phone does not catch the network and has stopped searching for it. This happens when the amplifier in the gadget breaks down, increasing the transmitter power. 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 yourself, as it may be necessary to check other parts, 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 best programs to speed up the Internet

You can speed up access to your favorite sites using special applications installed on mobile devices. Among the most popular and effective are:

Net Master is a free utility that allows you to quickly set up an Internet connection. Key features include checking connection speed, VPN protection, wireless connection control, as well as a convenient menu for managing and changing personal settings.
Network signal booster - the program helps improve signal quality by increasing power. The utility is very light and simple, but it turns out to be effective during operation. Support is always in touch.
HSPA+ Tweaker (3G amplifier) – the application is suitable for Android smartphones. Once launched, it optimizes your network connection using reconnection parameters. This makes it possible to significantly reduce ping in gaming mode, and also improves the quality of calls, the use of instant messengers, and videos on websites launch faster.
NetWork Master – Speed Test is a utility with a wide range of capabilities, suitable for Android devices. Simultaneously analyzes, optimizes and speeds up network access. The utility has an anti-virus module, an indicator of network capabilities, and optimization of access to sites from smartphones. The program will easily show the connection speed and can monitor gadgets that connect to the smartphone as a modem.
4G Connection booster is a tool for Android that increases the speed of network access on smartphones. This is achieved through optimization that occurs in less than 10 seconds.

For several years he worked in mobile phone stores of two large operators. I understand tariffs well and see all the pitfalls. I love gadgets, especially Android ones.

Ask a Question

Question to the expert

What is the most effective signal booster method for the Internet?

It is best to buy a mobile router for wireless network access, to which you can connect an antenna and so that the devices function in pairs.

Which amplifier should I choose for fixed mobile Internet stations?

It is recommended that you contact your provider or operator with such questions. If the speed was sufficient before the problems, then there is a possibility of violation of the antenna positions. In such cases, the fastening method is improved and adjustments are made.

What affects the Internet speed on a smartphone?

Much depends on the technologies that the operator uses and the range of the towers. In addition, a critical factor may be the simultaneous use of the network by people, as well as problems with sites and the device itself.

The network suddenly disappeared

When your phone doesn't connect to the network, you should look for the reason in its internal parts. If the signal suddenly disappears, this may indicate a breakdown of the radio path. This element is important for the operation of the gadget. It is connected to a lot of parts. It is impossible to check its performance at home, as well as to carry out repairs yourself. 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 telephone repair.

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.

Intermittent signal loss

Unstable signal, your phone can't connect to the network? Why does this happen even with new devices? In most cases, the reason is quite banal - unfair treatment of the device. Not every user knows 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 recommended to take the gadget to a service center, where specialists will perform diagnostics. This will determine the exact reason why the signal is being lost. If moisture penetration into the device is confirmed, the technician 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.

Green robot

If you own a mobile device that runs on the Android platform, then it probably has a 3G option. When you want to access the Internet using this connection for the first time, most likely, you will see a message stating that the function is inactive or configured incorrectly. Don't panic because before you can access the internet on your device, you'll need to set it up. Accordingly, you have a question about how to connect 3G to Android.

There is no cellular operator network

What should I do if my phone doesn’t connect to the network? An icon indicating no signal appears on the device screen. The machine does not attempt to connect to the network automatically. Every second owner of modern smartphones has encountered this problem. Most often the reason is a software glitch. If rebooting the device does 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 nowadays 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 to take this step, performs actions at his own peril and risk. After flashing the system, the gadget is automatically removed from warranty, so if something goes wrong, even experienced technicians will not be able to save the phone.

Internet Speed Master

You can speed up the Internet on your smartphone and tablet running Android OS using a special web application, the installation of which is free.

Note ! The utility is easy to use, but after installation it requires ROOT rights.

If it was not possible to purchase them, the algorithm of actions is as follows:

run the utility.
On the screen, select the line “Improve Internet Connection”.
In the pop-up window, click the “Restore” button.

To activate the specified parameters, they must be saved by clicking “OK”.

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.

Types of mobile networks

Here is a screenshot from a smartphone that can help you navigate how to set up a 3G network on your mobile phone.

LTE

Long-Term Evolution is one of the wireless communication standards. It is considered a descendant of GSM/EDGE and UMTS/HSPA; the transmission protocol is similar, but the speed of information exchange is higher. Although pure LTE is presented by operators as a 4G technology, its specification does not satisfy this condition and is prescribed by the 3GPP consortium as an intermediate one.

The ranges of this communication group differ by country, so the phone must be multi-band. And this can only be judged by indirect data from the website www.gsmarena.com. However, it is also wrong to classify LTE as the previous generation, because significant improvements have occurred. In fact, the standards are met by the LTE-A (advanced) specification, and it is called True 4G, and is designated 4G+. From the information on www.gsmarena.com it is not entirely clear what exactly Alcatel OneTiuch supports. Thus, the data cannot be called exhaustive.

Throughput has been increased by reducing the waiting time between packets, changing processing methods and nuances of radio signal modulation. LTE operates on its own frequency because it is completely incompatible with previous versions of wireless communications from cellular operators. The real maximum download speed is 326.4 Mbps, which is almost three times lower than real 4G. Uplink is twice as slow.

The division of channels (in addition to the code one) occurs due to the separation of frequencies and time. Along with South Korea and Japan, Kazakhstan is among the leaders of new generation cellular communications. The Russian Federation is somewhere in the middle of the list. The only consolation is that Kazakhstan has surpassed America in this regard. At long distances, the reception frequency decreases, and the actual speed can be 1 Mbit/s. In the Russian Federation, the bands mostly used are 2600 MHz, 1800 MHz (the most common, range up to 6.8 km) and 800 MHz. A number of useful frequencies in our country are still occupied by analogue television broadcasting.

LTE providers benefit from the fact that there are gradual upgrade algorithms from UMTS. But a cell phone will never give maximum performance. For this you need an external antenna. Then the speeds can become truly significant. And so LTE can be called solid 3G. Everything else is advertising gimmicks.

LTE-A

According to 3GPP rules, this protocol is described by the 10th version specification. LTE-A is one of the few officially recognized as the fourth generation of cellular communications. Improvements are achieved through purely quantitative methods. Not only does the channel bandwidth expand, but it also becomes possible to occupy separate pieces of the spectrum scattered across the range. In Russia, LTE-A was the first to occupy the Garden Ring. This happened on February 25, 2014. The network operated at a maximum speed of 300 Mbit/s, but for advertising purposes it was called 4G. Given the above, you need to clarify whether the phone supports LTE-A. If the answer is no, then there cannot be anything other than 3G Internet on the device.

UMTS

One of the most common 3G communication standards. Developed with the aim of introducing this concept into European everyday life. The theoretical speed threshold is 42 Mbit/s with HSPA+. Otherwise - half as much. Based on the GSM standard. Uses code channeling. In practice, the average speed is about a third of Mbit/s.

GSM

Second generation of mobile communications. It comes into operation when other protocols fail. On average, the channel carries a bitrate of 9.6 kbit/s. This is simply zero compared to modern 3G standards. One of the intermediate technologies is GPRS, which is often called 2.5G. The second generation includes:

HSCSD.

To the transitions between 2 and 3:

GPRS.
EDGE.
CDMA2000.

Why doesn't Beeline pick up the network today?

There can be many reasons for the Beeline network to disappear on your phone.

When you leave the city, you may accidentally end up in an area of poor reception or lack of Beeline coverage. As soon as you return to an area with good network reception, the connection will be restored.
Try rebooting your phone. Perhaps an accidental glitch caused him to “lose” reception of signals from Beeline cellular stations. After a reboot, the network may appear.
Remove the SIM card from the phone and inspect it: it may be damaged and is not registered in the Beeline network. If everything is fine with the SIM card, try inserting it into another phone. It is possible that the signal receiver in your phone is faulty.
If you have access to the Internet at home, go to the Beeline website and try to find out if maintenance work is being carried out in your area. Perhaps the lack of network is caused by problems or reconnection of the transmitting equipment at the cellular station.

Why doesn't Beeline pick up the 3G network?

If we are talking about a modem, it is possible that it may be damaged, and as a result, the connecting cable may fail. Try connecting to the 3G network from your Beeline phone.
If your Beeline phone does not connect to the 3G network, check whether the Beeline signal is covered at all. Without receiving a telephone signal and 3G, the network will not work.
Recently, cases of infection of mobile devices with virus programs that block access to the 3G Internet have become increasingly common. Check your device with a good antivirus.
The simplest option cannot be ruled out: Beeline is carrying out repair work, and the 3G network is temporarily disabled. Try connecting to 4G if your device supports this standard.
Check the status of your balance: if the funds on it are completely exhausted, or the prepaid traffic package has expired, you will have to top up your account in any available way to continue working.

Real 3G speed

The speed supported by the 3G connection reaches 42.2 Mbit/s, provided that the smartphone supports the HSDPA+ standard. If the phone only supports HSDPA, then the speed will be half as much – 22.1 Mbit/s. The actual speed is usually much less.

Connection speed can be measured using the Speedtest service. This application can be downloaded for iOS, Android, Windows Phone platforms. The program is easy to use and has only one “Start” button, located under the animated speedometer.

After measurement, the results: traffic speed and connection speed can be sent by email, for example, to the network operator. The Results tab stores data about previous measurements.

It should be noted that the speed may vary and depends on the region, signal strength and speed of movement. At a driving speed of 100 km/h, the speed of data transmission and reception drops several times.

One last piece of advice.
Practical measurements have shown that a smartphone in 3G mode consumes 20-30% more electricity. Therefore, if you do not need to use 3G communications all the time, then work in 2G (Settings menu), and the high-speed mode is turned on as needed. If it's convenient, of course. The technical information can be viewed very simply using the example of an MTS 3G modem that was sold several years ago. views
