There is no connection on the phone what to do. Mobile phone does not catch the network

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, the brand of the phone does not affect this 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 cellular network 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.

Faulty SIM card

Often the problem lies in the SIM card, which is responsible for communicating with the network. Items tend to fall into disrepair and "sim cards" are no exception. Especially if the card is often rearranged from phone to phone. This may damage the contacts. In this case, the phone simply cannot register on the network.

If the problem is in the SIM card, then diagnosing it is easy. Take another card and insert it into your phone. If the problem has disappeared, then the card needs to be changed. Go to the nearest mobile operator's customer service center and change to a new one.

The phone does not catch the network - the reason is in the device

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

Also, this problem is 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 telephone basics on your own. Experts will help you with this by determining the reason why the phone does not catch 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 the phone (dialer) and enter the code: *#*#4636#*#* , you will be taken to the engineering menu of the Android operating system. Go to the phone information, scroll to the middle, click on the button to turn off the radio, and then select the preferred network type GSM Auto, WCDMA preferred or WCDMA Only from the drop-down list.

GSM Auto - the phone itself will determine the best network coverage and select the required frequency, for example 2G / 3G / 4G.
WCDMA Preferred - will try to use 3G by default wherever possible.
WCDMA Only - always use 3G. By the way, this option does not work on some phones, for example Meizu.

If after selecting one of the three options, you still see the old option, don't panic. The desired option is selected and already saved.

Then press the button to turn on the radio again. Reboot the device, after rebooting the smartphone, you should have a network again. If this does not happen - write in the comments, we will try to figure it out.

And finally, I would like to say that if the engineering menu did not help you and Android still does not catch the network with another SIM card, then the problem may be in the antenna or radio module. In this case, it is necessary to return the device for diagnostics to a service center.

However, we note that the most common failure in a situation where the phone does not catch the network, 90% are 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 in itself is an obstacle to the normal operation of the antenna and signal reception. You can find out the cost of repairing the loop on our website, in the appropriate section. Just select your phone model and problem.

Often the problem of finding a network is not critical to repair and does not require much time. However, its mere presence is depressing, because it forces you to look for a way to call each time you have your almost working phone. So don't delay the renovation. And if you can’t identify the cause yourself, go to the experts.

Why is the phone not picking up the network? Other reasons

Additional reasons why the phone does not catch the network:

You are in an area with low base station signal strength. If you are far out of town, in a forest, in a basement, in the subway, in the depths of an old foundation 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 the loss of the network is caused by a low signal strength of 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.
If the phone stopped catching 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 about the problem.
The lack of communication may be due to the fact that the radio path has become unusable. To determine the problems, a complete diagnosis is required, carried out only by specialists.
The phone may not catch the network when the signal transmission power amplifier is out of order. To fix the problem, you need to completely replace the components. It is impossible to do this at home, so go to the experts.
Another common cause is related to moisture getting into the phone. If you accidentally dropped your phone in the bathroom or got it wet in the rain, then you need to go to the service for diagnostics as soon as possible, because over time this will lead to corrosion.
Phones from China. With the advent of access to the World Wide Web, every resident of Russia has the opportunity to buy cheap phones through Chinese online stores. It is worth noting that the difference in price is significantly different, but there are more risks. By purchasing a phone at an authorized point of sale, the buyer can inspect the gadget, try it in operation, and also receive a guarantee that provides free maintenance for a certain period. And what do shops in China offer? You can judge the purchased phone only by the picture. It is not always possible to find out the exact characteristics, so some buyers are faced with such a problem as the phone does not support the Russian cellular standard. In this case, the user can no longer do anything.

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

Why does the iPhone not detect the network?

There are many prerequisites that entail disruption of the smartphone.

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

reset to factory settings
device was flashed
iPhone has been repaired
the gadget has not been used for a long time
time set incorrectly

Sometimes iPhone does not find the network when exposed to inclement weather conditions or when incorrect software features are installed.

After updating the device, you need to check the cellular settings to make sure that all functions are available, the iPhone sees the SIM card and catches the network well.

Signs of broken Apple technology

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

Signs of a malfunctioning network include:

the gadget does not see the cellular network
iPhone lost network and can't find it
bad signal reception
looking for internet providers
constantly displays the inscription "Search"

Also a sign of a problem is the situation when the connection on the smartphone disappears in a place where there is no network, but when it returns to the coverage area, it weakly resumes. If the iPhone writes “Search” and does not find the operator for a long time, then there are malfunctions that need to be fixed.

If the 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 the iPhone does not catch 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"
reboot gadget
extract and inspect the sim
check for updates
insert another sim card

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

If these steps did not help, and you do not know what the problem is, you can try resetting the network settings. If, after performing these steps, the mobile device does not see the cellular network or finds the operator poorly, then you need to seek qualified help from specialists who will diagnose the device, be able to quickly determine the cause of the breakdown and fix the problem.

An annoying problem that many users face is that the phone does not catch the network. Once in this situation, it is easy to feel cut off from the world.

To begin with, it is worth seeing if there is at least some level of signal reception on the display. If yes, it is quite possible that you have selected a network that is not supported by your operator. In this case, fixing the problem is not difficult. Just go to "settings" and select the network search function "automatically". In case of failure, specify the required network manually in the same menu.

Why is the phone not picking up the network?

There are several reasons why there is no network in the phone. Consider the possible options:

The network on the phone is gone - it means that the radio contact is out of order. It is impossible to eliminate such a breakdown on your own, since the radio contact is a complex mechanism consisting of many elements. Finding out which of them is out of order is possible only with the help of a complete diagnosis in a service center.
The phone stopped catching the network (does not search for a network). This indicates a breakdown of the transmitter power amplifier. The only way to fix the problem is to replace the part. At home, it is impossible to make such repairs. To solve the problem, you should contact the service center for the repair of mobile phones.
The phone does not catch the network well. In this case, the reason lies in a faulty antenna. Since the antenna is a rather fragile device, it often stops functioning due to a strong impact or when the phone is dropped. Replacing the antenna will fix the problem.
The phone cannot find the network and writes that there is no signal. This indicates a software failure. To resume normal operation, the phone needs a flashing. You can qualitatively reflash the phone only in the service center.
The phone loses the network. Most often this happens due to the fault of the user or due to flooding of the device. To find out the cause of the malfunction, you must return the phone to a service center for diagnostics. If the phone has been exposed to moisture, you need to contact the service center specialists as soon as possible, since the corrosion that has begun is killing the phone more and more every minute.

Common causes of malfunction

You are in an area with low base station signal strength
If you are far out of town, in a forest, in a basement, in the subway, in the depths of an old foundation 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 the loss of the network is caused by a low signal strength of 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.
Software failure
If the problem with the network is caused by a software failure, perform the following operations in sequence: remove and insert the battery, if it doesn’t help, do a soft reset through the menu, if it doesn’t help, do a hard reset through the service menu. For android, this is a certain key combination: you need to turn off the device, hold down the volume button and at the same time the power button for 3-5 seconds until the service menu appears on the display. For different models, different key combinations are used (volume up, volume down, home button), but always with the simultaneous pressing of the power button. In the service menu, use the volume buttons to select the item wipe data or factory reset. A hard reset will completely delete all client data from the device’s memory (book, photo, installed programs, etc.), i.e. the device will return to the factory state in which the device was when the device was purchased. If a hard reset does not help, then your device needs a software update in our authorized service centers using official programs provided by phone manufacturers. By updating the software in our authorized service centers, you can be sure that you will be installed with the latest latest version of the software from the manufacturer.
Defective antenna, antenna key, radio processor, power amplifier, displetor, etc.
If your device stopped seeing the network in the zone of reliable reception, then most likely a component repair and electrical replacement of the radio unit chips are required. Self-repair by the user of such a defect is not possible. In our SC, they will diagnose the main board, determine the damaged microcircuit and replace it with the help of a soldering station, and in case of damage to the microcircuits of the radio unit under the compound (glue), they will replace the entire main board with a new one.

MegaFon boasts a decent cellular coverage area - it is present in almost all regions, so communication problems rarely occur. Stable reception, high-quality voice services, relatively fast Internet - this is what this operator can please us with. Let's see what to do if there is no network on MegaFon. This rarely happens, and there are many reasons for this.

Technical work at the operator

If the MegaFon network on the phone is lost, you should immediately do one simple operation - restart the mobile phone and wait for re-registration in the network. This procedure is universal, that is, you should restart your phone every time it stops seeing a cellular network signal– only after that other actions are performed.

If rebooting the phone did not bring visible results, it is quite possible that MegaFon is holding some kind of events on the network. This may be the reason for the lack of acceptance. In order to check the guess, it is advisable to somehow clarify whether other subscribers have reception. If the lack of communication is widespread, then the problem lies in technical breakdowns or work on the operator's equipment - wait 20-30 minutes, then try restarting your phone again.

The phone is broken

Unfortunately, not a single mobile phone is insured against breakage - it is simply impossible to ensure 100% reliability with current technologies. If you find that there is no network on MegaFon on your phone and its presence on other people's handsets, most likely something has happened to your device. You can check the performance of your mobile phone using another SIM card. If the mobile phone still does not work, give it for repair by choosing a good service center.

Damaged SIM card

Some subscribers perceive the facts of SIM card breakdowns with surprise on their faces. In fact, there is nothing surprising here. Like any other electronic device or module, a SIM card can fail because a microcircuit is installed inside it. If it breaks, the phone will not be able to register in the MegaFon network. The result will be a complete lack of communication - the antenna indicator will not display the presence of a network signal.

But it's too early to get upset - even though the SIM card is out of order, you can always restore access to your phone number. To do this, you need to arm yourself with a passport and contact the nearest MegaFon service office. Here you will be given a duplicate SIM card, which will need to be installed in the phone - now the mobile phone will be able to register on the network.

Before sending to the service office, make sure that your number is issued specifically for you. Otherwise, the issuance of a duplicate will be refused.

No network in the area

Now you know what to do if the MegaFon SIM card does not work and there is no network - you need to contact the service office for a duplicate. At the same time, the balance, tariff and service sets are fully saved on your number. Let's find out what to do if you arrive in any locality and find that there is no MegaFon network coverage. First you need to send the phone to reboot - it is quite possible that some kind of network error has occurred that prevents the registration of the mobile phone.

If the reboot helped, that's good. But if the results turned out to be negative, you need to make sure that there is MegaFon coverage in the area. In Russia, there really are settlements where a limited number of operators operate - for example, only MTS or only Beeline. It is possible that you were lucky enough to get into places where there is no MegaFon network.

There is only one way out of this situation - to purchase a SIM card from the operator that definitely works in the area.

Now you know what to do if there is no MegaFon network - you need to check in sequence:

phone performance;
SIM card performance;
The presence of MegaFon in a particular area.

If you know for sure that there is a network here, but for some reason registration does not occur, you should go to the settings and perform a manual search - sometimes this helps if there is no network on MegaFon.

If you came to this page, then most likely your phone has stopped seeing the Wi-Fi network, or networks. It can be a home network, somewhere away, a public wireless network, etc. The problem is that the network we need does not appear in the list of available ones on the phone. He simply does not find it, does not see it, and, accordingly, it is impossible to connect to such a network. It is not uncommon for a mobile device to not find a specific Wi-Fi network. Which, for example, a laptop sees and connects without problems. Or it may be that the phone does not find any network, but other devices see them and work fine with them.

In this article, I will try to collect all the most popular causes and solutions that can help you solve this problem. As usual, first it is desirable to find out what the problem is: in a mobile phone, or a Wi-Fi router. If the problem is with the Wi-Fi network at home, then we have a better chance of fixing everything, since we have access to the router itself. If this is someone else's network, then it is unlikely that something will be done.

In fact, it doesn't make much difference on which device you have a problem. It is clear that this is most likely an Android or iOS phone. Well, maybe Windows Mobile. Since this problem can hardly be solved in the settings of the mobile device itself, it doesn’t matter what device you have. It's the same with a router.

I have already written separate articles on Android and iOS devices:

The phone does not see the Wi-Fi router: possible reasons

1 Disable / enable Wi-Fi, restart your phone and router. To get started, just go to your phone settings and turn off Wi-Fi. I think everyone knows how to do it.

Then turn it back on.

Reboot the phone:

On Android, just press and hold the power button, then select Restart. Depending on the manufacturer and version of Android, the steps may be slightly different.
On iPhone, press and hold the Home button and the Power button. The phone will reboot.

We reboot the router. If you have access to it. It is enough to turn off the power for a minute and turn on the router again. You can perform multiple reboots in a row. More details can be read.

2 We determine what is the reason.

Check all three items:

If your phone does not see any Wi-Fi networks, but they exist and other devices find them, then it is clear that the problem is specifically in your smartphone. All I can advise is to reboot it, and remove the cover from it. If he is. If this does not help, then you can try performing a hard reset. If this does not help, then you will have to carry the device to a service center.
When a device does not find one network, the first step is to check if other devices can see it. If they do not see, then most likely the problem is on the side of the router. Let's reboot it first. If this does not help, then see the article:.
If other devices find a Wi-Fi network, but your phone does not, but it sees other networks, then the problem is most likely in the router settings. As a rule, changing the wireless network channel and region helps. Below I will talk about this in more detail.

3 Change the router settings.

You need to go to the settings of your router, go to the section with Wi-Fi settings, and try to set a static wireless network channel and another region. You can also set the channel width to 20 MHz. It's better to take turns.

On TP-Link routers, it looks like this:

More details in the article:. You can experiment with the channel and region. For example, put the region USA. If you have a static channel set in your settings, then set it to "Auto".
