Why is there no signal from the cellular network megaphone. Why is there no MTS connection?

Sometimes it happens to owners of smartphones running the Android operating system that the phone stops receiving the network. To find out why a smartphone does not catch the network, first of all you need to understand whether there is a problem with the SIM card and cellular operator or a problem in the device itself.

It often happens that a smartphone does not catch the network due to poor coverage mobile operator or simply given frequency not supported. For example, the 4G (LTE) signal is received mainly only in large cities and does not work at all outside the city. The problem may also be a broken SIM card. In any case, you first need to check the network functionality of different cellular operators. If none of them work, then read below.

The phone bought in China does not connect to the network.

What phone number do you have? If you bought a phone from China and it, for example, does not receive 3G or 4G, then the whole problem is that the frequencies in China and Russia do not match, there is nothing you can do here. That is why everyone advises buying phones from abroad with European firmware and European communication standards, which, as you may know, differ from those used in Asian countries.

The Android smartphone stopped connecting to the network after the firmware update.

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 your phone (dialer) and enter the code: *#*#4636#*#* , you will end up in engineering menu operating system Android. Go to phone information, scroll to the middle, click on the turn off radio button, and then select configure your preferred type from the drop-down list GSM networks Auto, WCDMA preferred or WCDMA Only.

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, do not panic. Required option selected and already saved.

Then press the radio button again.

Reboot your device, after rebooting your 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 in another way SIM card Android still does not catch the network, then it may be the antenna or radio module. In this case, it is necessary to submit the device for diagnostics at service center.

In most cases, the problem of signal reception deterioration can be solved at home, or by contacting the operator cellular communications. But in some situations it may be necessary service repair, replacement of individual components. Let's look at the most common reasons why the mobile network becomes unavailable on Android, as well as methods for solving them.

Without a mobile network, a smartphone turns into a sophisticated toy with which you can listen to music, watch a movie and play an application. It’s no longer possible to call from him, which means she’s lost main function mobile phone The first and most common reason for absence mobile communications there is a problem with the SIM card. In this case, several scenarios are possible:

• The SIM card is blocked by the operator. As a result of a long period of inactivity, the operator intentionally blocks the SIM card, and, accordingly, such a card cannot receive a signal.
• The SIM card is damaged. With prolonged use, as well as frequent replacement of the SIM card, its contacts may be damaged. As a result, a phone with a weak radio module may have poor reception or even display the message “mobile network not found.”
• The SIM card is cut incorrectly. New Android smartphones can only support SIM cards of -micro or -nano sim. This means that the user needs to trim his old SIM card to the required sizes. If you do this at home, you can damage the contacts and ruin the card, which will not receive a signal. mobile operator.

A similar situation often arises only when using the same SIM card for a long time. Although in some situations the problem may appear in the first days of operation. Let's consider how this problem can be solved.

How to solve a problem

If your Android phone does not see the cellular network, then try inserting another SIM card into it and preferably from the same operator. In the case when the smartphone immediately will find the network, then the problem is definitely in the SIM card. If it is blocked, you can contact the service center of your mobile operator to remove the blocking. But if it is damaged, then it will not be possible to save it. You can only restore old number phone number in the customer support center, which will be assigned to the new SIM card.
When cutting a SIM card to -micro and -nano sim formats, it is recommended to take the help of professionals mobile center. They have a special device for this, a stapler, the dimensions of which strictly correspond to the necessary standards. And when performing this operation yourself, you should be careful not to damage the SIM card contacts.

The reason is the smartphone

If, even after replacing the SIM card, the phone displays the message “no connection to the mobile network,” then the problem is probably in the device itself. At the same time, it bifurcates into two components:

• Software. For example, failure of mobile network settings or mobile phone software as a result of updates, viruses, etc.
• Hardware. As a result of falling, careless handling and wearing without a case, the cable of the mobile phone is damaged and problems with the antenna may occur. Problems of failure of the radio module can also be: electrical short circuit, prolonged exposure to low or high temperature conditions.

If the phone crashed just before the selected mobile network stopped working, then the problem is probably in the mobile phone. Don’t immediately despair and run to the store for a new one. After all, the problem with a certain degree of probability can still be corrected. Let's consider what to do in this case.

How to solve a problem

If the cause of the problem lies in a software failure, then you should go to the menu system settings Android and select the “Automatic” network search mode. When this method did not give the desired result, and the network still does not work on the phone, configure it manually. As a last resort, restart your mobile phone and reset it to factory settings.
If the cable or the radio module itself is damaged, they will need to be repaired or replaced. You can do this work yourself, but it is safer to contact a specialized service center. The cost of the work will depend on the brand of your phone and the extent of damage. We recommend watching a training video on replacing the antenna on an Android phone.

The reason is incorrect flashing

One of the most common reasons why the signal disappears in phones running Android OS is incorrect flashing. Installing custom firmware, which have higher functionality, personalization capabilities, etc., is fraught with compatibility problems with specific model phone. As a result, system failures occur, which can also lead to the phone no longer seeing the network.

How to solve a problem

Instructions for custom firmware

If the firmware used is not compatible with the version of the communication module used in the phone, then you just need to install the required version of the custom firmware. To do this, before downloading zip archive, read the instructions and find out for which smartphones it is intended.

If the firmware is compatible with your smartphone, but there is still no network, then use the following method. Through the file manager, we find the Dev Tools application preinstalled in memory. Having launched it, click on the item Bad behavior - Crash the system server and restart the mobile phone. After a normal reboot, the phone will begin to display the reception of your operator's network.

You should also not forget about the banal reasons why your Android may not receive a signal. These include being outside the operator's coverage area or not having a SIM card in the corresponding slot on the phone. Only after checking that this is not the case should you begin to eliminate the causes using the methods described above.

A comment

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 very inopportune moment. Users often discuss this topic on the Internet. Surprisingly, the brand of the phone does not affect this 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, it is necessary to check whether there is a signal cellular network. An icon should appear on the home screen. It often happens that the user chooses a network that is not supported by the operator. All necessary information 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.

Faulty SIM card

Often the problem lies in the SIM card, which is responsible for communicating with the network. Items tend to deteriorate and SIM cards are no exception. Especially if the card is often moved from phone to phone. This can cause contacts to deteriorate. In this case, the phone simply cannot register on the network.

If the problem is with the SIM card, then diagnosing it is easy. Take another card and insert it into your phone. If the problem disappears, then the card needs to be changed. Go to the nearest mobile operator subscriber service center and change to a new one.

The phone does not connect to the network - the reason is in the device

On at this stage The problem is divided into software and hardware. First, check your settings. Perhaps, through the spontaneous intervention of your children or the children of your guests, they were shot down. To do this, go to the “Settings” of your phone and select the “Automatic” network search mode. If this does not help, try to find the network manually directly from your operator.

Also this problem possible due to incorrect firmware if you have recently used it. Or software glitches. They should already be diagnosed by specialists; it will be difficult to figure out the basics of telephone yourself. Experts will help you with this by determining the reason why your phone does not connect to the network, completely free of charge.

If you had signal reception before the firmware, then you need to select the frequency settings. To do this, go to your phone (dialer) and enter the code: *#*#4636#*#* , you will be taken to the engineering menu of the operating room Android systems. Go to the phone information, scroll to the middle, click on the turn off radio button, and then select from the drop-down list to configure the preferred network type GSM Auto, WCDMA preferred or WCDMA Only.

• 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, do not panic. The desired option is selected and already saved.

Then press the radio button again. Reboot your device, after rebooting your 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 with another SIM Android card If it still doesn't pick up the network, it might be the antenna or radio module. In this case, you must send the device to a service center for diagnostics.

However, we note that the most common breakdown in a situation where the phone does not receive the network, in 90% of cases, is problems with the antenna. As a result of falling or careless handling of the phone (throwing it on the sofa after a conversation, carrying it in a bag without a case), the cable is damaged. Which of course is an obstacle to normal operation antennas and signal reception. You can find out the cost of repairing the cable on our website, in the corresponding section. Just select your phone model and fault.

Often the problem of finding a network is not critical to repair and will not require much time. However, its mere presence is depressing, because it forces you to look for a way to call every time if you have your almost working phone. So don't delay with repairs. And if you cannot identify the cause on your own, go to specialists.

Why can't my phone connect to the network? Other reasons

Additional reasons why the phone does not connect to the network:

1. You are in the zone with low level signal strength base station. If you are far out in the country, in the forest, in a basement, in the subway, in the depths of an old building with meter-thick brick walls, and your device shows a low network level or has lost it altogether, then most likely your device is working. And network loss is caused by low signal power from the base station in a particular location. Also, the loss of the network by the device can be caused by a temporary shutdown of the base station itself on the operator’s side.
2. If the phone stops receiving the network after contacting the service, then most likely the problem is of a software nature and the technicians simply updated the firmware incorrectly. Contact the service and tell us about the problem.
3. The lack of communication may be due to the fact that the radio path has become unusable. To identify problems, a complete diagnosis is required, carried out only by specialists.
4. The phone may not receive the network when its signal transmission power amplifier fails. To fix the problem, you need to completely replace the components. It is impossible to do this at home, so go to the specialists.
5. Another common cause is due to moisture getting into the phone. If you accidentally dropped your phone in the bathroom or got it wet in the rain, you need to go to a service center for diagnostics as soon as possible, since over time this will lead to corrosion.
6. Phones from the Middle Kingdom. With the advent of access to World Wide Web Every resident of Russia now 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.

Many people are interested in which phone catches the network better, especially in unusual situations. According to existing reviews and some studies, Nokia devices stand out in this regard.

Why doesn't iPhone detect the network?

There are many prerequisites that lead to disruptions in the operation of a smartphone.

If the iPhone has stopped receiving the network, this means that one of the following reasons is present:

• Reset to factory settings was carried out
• device firmware was being flashed
• iPhone was repaired
• the gadget has not been used for a long time
• the time was set incorrectly

Sometimes iPhone does not find the network when exposed to adverse conditions weather conditions and when installing incorrect software functions.

After updating the device, you need to check the cell phone settings to make sure that all functions are available, the iPhone sees the SIM card and has good network reception.

Signs of Apple equipment breakdowns

It happens that new smartphone does not see the operator’s network even in an area with an excellent signal, this indicates problems with your device.

Symptoms of an incorrectly functioning network include:

• The gadget does not see the cellular network
• iPhone lost network and can't find it
• poor signal reception
• looking for Internet providers for a long time
• constantly displays the message “Searching”

Another sign of a problem is the situation when the connection on the smartphone is lost in a place where there is no network, but upon returning to the coverage area, it is weakly restored. If the iPhone says “Search” and does not find an operator for a long time, then there are problems that need to be fixed.

If a smartphone catches the network well, but connects poorly to it or loses it, this means that it needs repair.

How to fix the problem yourself?

If your iPhone can't connect to the network, you can try to fix the problem yourself.

To do this you need to perform a number of specific actions:

• check network settings
• turn on and after 10 seconds turn off “Airplane mode”
• overload the gadget
• remove and inspect the sim
• check for updates
• insert another SIM card

If your phone does not find an operator while abroad, follow these steps. Turn on the “Operator” item in the settings menu and select the “Automatic” function. After this, you will see a list of mobile operators and available mobile networks, from which you can choose the appropriate one. If everything worked out, this indicates that the iPhone is working properly.

If these steps don't help and you don't know what the problem is, you can try resetting your network settings. If after performing these steps mobile device does not see the cellular network or has difficulty finding an operator, which means you need to contact qualified assistance contact specialists who will diagnose the device and be able to quickly determine the cause of the breakdown and fix the problem.

Poor mobile signal reception or simply “no network”, quite common problem when working with modern smartphones. In some cases, it “does not catch” due to the large distance to cell towers; other malfunctions occur due to errors in the operation of the software or hardware parts of the device.

Some problems can be solved by changing the phone settings; to resolve others, you need to contact your mobile operator or the manufacturer’s service center.

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 quite common reason. 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.
• Device infection with malware software, which can affect signal reception.

SIM card malfunctions

If you suspect that your SIM card has failed, first try installing the problematic card in another device. Everything works fine - that's not the problem. If your smartphone has 2 SIM slots, move the card from one to the other.

This procedure can be performed independently and does not require disassembling the phone case. If you determine that it is the SIM card that is broken, contact the service center of your mobile operator for help. Registration services new card usually free when the old one is out of order, but a passport may be required.

Communication module failure

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

• Disabling the loop SIM slot or antennas are 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.

Provider failure

In some cases, it is enough to wait about an hour and the problem will go away on its own. There is an overload of equipment on the side of the cellular operator, as a result of which the entire network goes down. Technical specialists react very quickly to such accidents with cell towers and correct the situation in a matter of minutes.

Checking the settings

Android and iOS devices may “lose” the signal after errors in the operating system. Below is how to set up the network on your phone.

1. Open the notification shade and go to the device settings.
2. Go to the " Mobile points access" and find the list of SIM cards. If your card is not detected, check whether it is installed correctly in the slot. Open the "Access Points" menu.
3. Click on the "Add" button. In the window that opens, enter the parameters for the current configuration.

Important! All necessary data can be found on the mobile operator’s website. If you do not find information on the web portal, contact any of the offices and request data from consultants.

1. Save the information and check whether the cellular signal is working (as an option, whether “sticks” have appeared in the status bar of the device).
2. Tap on the “Search...” item. The phone will scan for available access points. The procedure can take from 30 seconds to several minutes on older Android smartphones.
3. After completing the search, click on the name of the mobile operator whose SIM card is in the phone.
4. Check if the “Data in roaming” checkbox is checked. Try turning the radio button on and then off again.

Reset

After incorrectly flashing the device, the network may periodically disappear or work intermittently. In this case, it is necessary to carry out full diagnostics device and return the factory firmware.

In “especially advanced” cases, one cannot do without full reset 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.

Roaming error

The signal may disappear when weak signal or incorrect setting roaming parameters. To resolve most problems, simply restart your smartphone or reset your network settings. How to do this is described in the previous paragraph.

Incorrect firmware

If you flash your device with incompatible firmware or perform the procedure incorrectly, the communication module drivers may fail. At the same time, the message “No network” will be displayed on the screen. In some cases, it will be enough to reflash the gadget back to the factory one iOS version or Android, sometimes you will have to turn to specialists for help.

Conclusion

Problems with cellular communications occur due to various reasons– in some cases the fault lies with the operator, but most problems are caused by user actions. If malfunctions are detected - cell phone it says the mobile network is unavailable, it is best to contact a service center, but a normal reboot, reset and replacement of the SIM card can be done at home.
