The phone is inaccessible, although it is turned on and working

Android is far from a perfect platform. Therefore, there is nothing to be surprised that from time to time certain incidents occur with its users. Either the application does not load , then the charger runs out too quickly , then updates do not arrive , or it is impossible to answer the call. But if the first three problems are guaranteed to depend on the smartphone, then for some reason the last one is always blamed on the operator. But this is not always the case. So, before you complain to tech support, try doing a few things yourself.

If they can’t reach you, there are different ways to solve this problem.

The reasons why you cannot receive a call can be very different. It makes no sense to list them all, especially since they can be combined into one term - “failure”. After all, that’s what they call problems that cause something to not work. But for us this is not so important. It is much more important to be able to correct the situation. And, if it doesn’t work out, ask for advice in our Telegram chat.

SIM card damaged

The reason that the phone becomes unavailable for calls is sometimes a damaged SIM card. It may stop working if it was recently removed and then the contacts were accidentally damaged. Problems can start with an old SIM card that has been used for many years. Damage may occur due to the phone being dropped, hitting a hard surface, or coming into contact with water.

It's easy to check - insert the SIM into another mobile device. If it doesn't work or there are any interruptions, you just need to replace it with your mobile operator. It's free now.

How to contact a subscriber - solutions

Since a subscriber may be unavailable for several reasons, it is worth using several methods to contact him. Consider the following options:

Phone damaged

Shocks and falls can damage not only the SIM card, but also the phone itself. If problems with the connection appeared after mechanical impact on the device, this may be the problem. You can detect a phone failure in the same way as in the case of a SIM. It is enough to transfer it to another smartphone and check whether calls have resumed. If this happens, the problem lies in the device itself. However, the fault may not only be damage, but also other factors, which are described in more detail below.

Fixing a glitch in the phone software

So we checked the phone settings and everything is fine, we checked the SIM card - it is also working. But, they still can’t get through to you, it’s time to look for a problem in the phone software. To identify the error and correct it, you need to take the following steps:

Activate Flight mode for 20 seconds.

After turning off “Flight”, check whether incoming calls are received or not. If there are still no calls, proceed to the next step.

Restart your smartphone.

After each step, check whether you can be reached by phone.

Check the apps on your smartphone.

Calls are often blocked due to incorrect settings in the Black List or Call Recording applications. I recommend removing applications from unknown sources.

Check your smartphone for viruses.

To do this, you must first connect it to your computer in “Storage” mode in order to scan the files for viruses with a computer antivirus program. Then install an antivirus application (for example, Kaspersky Internet Security or Security Master) and check your smartphone. With viruses, people trying to call you usually hear “Busy” or a message that you are offline.

Clear the Phone app cache.

Go to your phone settings in the “Applications” section. Among all the applications installed on your smartphone, find “Phone”. Clear the cache and data in it, and then stop and start the application again. On some smartphones, this application may be called "com.android.phone".

Soft reset.

Save all the necessary data in the cloud or on your computer. Turn off your smartphone, remove the SIM card and press the volume-down and power buttons simultaneously. The smartphone will start in recovery mode. Use the Volume buttons to select Soft Reset, and then confirm by pressing the Power button. In some phones, such a reset can be done from the settings.

Hard factory reset

Since the soft reset did not help, then again go to recovery or system settings and do a hard reset (Wipe data/factory reset).
The phone will return its settings to factory settings - like new. These steps will resolve almost any phone software issue. A reset should only be used in very extreme cases, as applications are removed and all content is erased. It should be noted that some viruses are resistant to resetting, so follow all the points and steps in the order in which they are written. Then you won’t have to look for an answer to the question “why can’t they call me?”

Lack of communication

The inability to reach a subscriber can be explained by a simple lack of communication in certain places. For example, in densely built areas (with a large number of high-rise buildings), with poor coverage, as well as in basements and even elevators. There, the phone may not be accessible at all times until the owner physically moves it to another location or area.

Subscriber is out of network coverage area

Each operator has a coverage area, which cannot be 100%. In some areas there is no connection at all. There may be several reasons for this; in particular, it is inappropriate to organize a broadcast zone in this territory. If a person is in such a place, his mobile phone simply cannot register on the network. If at this moment someone tries to call us, he will hear an automatic voice recording in the handset stating that this number is unavailable.

Questionable applications

Programs downloaded from unverified sources can negatively affect mobile communications. If the owner thoughtlessly installs dubious applications and also gives them access to various phone functions, they can end up managing the settings of the mobile device themselves. To fix this problem, you need to completely remove unverified programs. After this, it is recommended to additionally check the phone for viruses using an antivirus application.

What services limit communication?

Restrictions are set for non-standard reasons. For example:

. The ban is created by the user himself, specifying a monthly limit on call minutes in the contract. When the limit is reached, the operator blocks all outgoing calls to the subscriber;
may be limited by company owner for corporate phones. The boss specifically sets a limit or a list of white numbers that the user can call. There is a ban on other directions;
Incoming calls while roaming may also be blocked. All this is done for the sake of preserving the funds of the number owner.

The subscriber can independently stop receiving calls and outgoing calls if he goes on a business trip. Each operator, including Megafon, has a service that helps to create a call ban without terminating the contract.

For your information
In this case, the subscriber may be charged a daily payment for the action of suspending the connection.

Using mobile internet

This factor often applies to smartphones with dual SIM cards. In some of them, heavy use of the mobile Internet may prevent calls from being received. Therefore, in order for the phone to stop being inaccessible, you need to temporarily turn off the mobile Internet. If the problems disappear, then the problem may lie in both the phone (it has only one radio module, which processes either calls or the Internet connection) and in the SIM card, which is worth consulting with your mobile operator.

Why can't my phone calls go through?

In order not to miss calls, it is important to prevent such a situation, and if it does occur, you need to understand what needs to be done to correct it. When a person tries to figure it out and contacts the caller, he finds out that he heard a busy signal. Below we discuss in detail the main situations when this can happen and suggest ways to solve the problem.

SIM card or tray is faulty

One of the most common reasons is a faulty SIM card. This can happen for various reasons:

When used, it is scratched by metal contacts, which leads to additional wear over many years.
Dust and pollution are often an integral part of life. When contacts become dirty, contact deteriorates and malfunctions occur.
A person can use their SIM card for many years. During this time, it wears out and its performance deteriorates.
In some cases, damage may result from mechanical impact.
Chemical reactions, such as oxidation, may occur when some liquids come into contact.

If there is a problem with the SIM card, you need to remove it from the tray and carefully inspect it for damage or dirt. If there is such a possibility, you can put it in another phone and check its functionality. You can also put another card from the same mobile provider in your phone. As a result, you can know for sure whether the card is working properly.

In some cases, stains can be removed by gently scrubbing the surface. In case of serious damage, you must contact a specialist for replacement. It must be remembered that sometimes the problem occurs when the user cropped the card himself.

Sometimes the card remains fully functional, but malfunctions occur in the tray. For example, when there was an attempt to take it out, but it got stuck. In this case, you must act carefully so as not to damage either the card or the tray.

Contacts may oxidize. This can be verified by their appearance. If this happens, then you need to clean them. Usually after this the problem disappears.

Incorrect operating system update

A modern smartphone is not only a means of communication, but also a full-fledged computer. There is a sufficient amount of system resources for effective work, a powerful processor, a high-quality operating system and everything that is necessary for work.

The manufacturer is constantly working to improve functionality, develop the operating system and core applications. The result of this activity is the appearance of new firmware, which is published on the manufacturer’s website. The operating system is usually updated automatically, in each case receiving the consent of the phone owner.

The update procedure, as a rule, is carefully debugged and occurs without any problems. However, in some situations failures could not be avoided. This applies to the following cases:

As improvements are made and previous inaccuracies and shortcomings are eliminated, extensive code changes occur. The results of their actions are very difficult to predict, and sometimes almost impossible. Therefore, updating the operating system in very rare cases can lead to problems with the operation of various nodes, including making an incoming or outgoing call.
The update procedure cannot be interrupted. Although it starts at the user's command, he cannot always wait for it to complete. For example, if the battery charge runs out, the procedure will be interrupted at a random moment. Because of this, various violations can occur, including making calls.
When performing a manual update, the corresponding code must be downloaded from the manufacturer's website. It is important that it is designed exactly for the model that the user has. If he downloaded a file related to another phone, then the result of the update cannot be predicted.

If a problem occurs due to an incorrect update, you need to roll back the update and perform it again. In this case, everything must be done accurately and carefully.

You also need to remember that the latest update must be installed on the gadget. Usually the smartphone itself warns about its appearance, but sometimes it may miss the appearance of a new version. In order not to miss it, it is recommended to regularly check for new firmware on the manufacturer’s website.

Software failure

If you have to deal with the problem of missed calls, then first of all you need to make sure that the SIM card is working properly. If the reason is different, then the most likely cause may be a software failure.

Typically, a user uses a large number of applications. In some cases, they may impair the functionality of the phone. In this case, it becomes necessary to check which program caused this. Sometimes problems can arise due to the installation of programs from third-party sources.

In this case, you need to be sure that the application does not contain malicious code and is made so well that it does not impair the functionality of the smartphone. To check, it makes sense to uninstall it, and then check the card’s functionality again.

In some cases, applications may have introduced a computer virus. To check this, just connect your smartphone to your computer in “Storage” mode and check it using an antivirus program.

Problems on the operator's side

If problems arise, it is not necessary that the reason is in the phone. Sometimes this is due to poor connection quality in certain places. To avoid this, for example, in the country, you can use signal amplifiers.

If the load on the operator in this area is high due to a large number of calls, then he may not be able to cope. This may also be the reason why calls are not being received.

To maintain a mobile network, it is necessary to carry out regular maintenance. Communication problems often arise at this time. The user can find out about such work by calling the provider's technical support service.

In all of these cases, you need to make sure that we are talking about problems on the part of the operator. By calling him, you can clarify what to do to avoid such problems in the future.

Mobile Internet included

If mobile Internet is actively used during a call, this may lead to communication failure. However, this happens extremely rarely.

Conflict between two SIM cards in a smartphone

Some mobile phones have trays for using two SIM cards. This is very convenient for the user. Although you have to pay for both, there can still be important advantages in each case. In each case, the subscriber can choose the card that is more profitable to use.

However, you need to remember that both cards are used by one module. Therefore, during a conversation on one of them, you may not receive a call on the other. This situation cannot be avoided. Therefore, the user should regularly check for missed calls.

Problems with the radio module

If normal measures do not restore normal communication, the problem may be due to a faulty communication module. In the event of a hardware failure, you should contact a specialist to fix it.

These types of problems can occur due to strong mechanical stress, water ingress or other similar reasons. Risk factors also include wear and tear of equipment or the use of defective parts.

Self-repair in such situations is undesirable. This is due not only to the fact that repair requires painstaking work, but also because the damage can be microscopic in size. In the latter case, you will not be able to detect them yourself (for example, they may be microcracks).

In some cases, only replacement of the damaged unit will be required. In this case, the cost of repairs may be slightly less.

Problems with IMEI

When performing the firmware, IMEI changes may occur. To check this, you can use the command *#06# - after dialing it, you must click on “Pick up the phone.” After this, the phone's IMEI will be shown on the display. It needs to be compared with the one specified in the technical documentation - they must match. If we are talking about different values, then you will need to contact the service center to restore the correct value.

You can also do this yourself by performing a factory reset. This option is preferable for experienced users, since you will need to install all the necessary updates, install the necessary applications and re-specify your settings.

Problems with firmware update

A failed firmware update may cause your phone to stop receiving incoming calls. You need to check whether the mobile identifier (IMEI) number matches the one listed on the smartphone box or under its battery. To do this, just enter the code *#06# on your phone, and then compare the number that appears on the screen with the phone code. If it does not match, you will need to reflash the phone, which is best handled by specialists at the service center.

If your phone is constantly busy, read these instructions.

Can't they call you? Check your phone settings!

The first place to look for the reason is the phone settings. Often users themselves get tricky with the settings. The reasons why they may not reach you are the following:

you have added a number to the blacklist;
there is a ban on incoming calls;
There is a restriction of calls for subscribers not included in the phone book.

Check your Call Barring settings

Go to the “Phone” application and go to settings, they are usually located in the upper right corner of the screen; these are icons with a gear or “hamburger” (three vertical dots. You need to check how the markers are set in the “Call barring” item. Then check the numbers on the black list. It is likely that in it you will find the number of the one who tells you: “I can’t get through.”

Check your Call Barring settings

Check your Forwarding settings

Another point to check is redirection. If forwarding is enabled, you need to configure it correctly. It is better to enable redirection:

if you are out of network access;
if you are talking to another party;
Always.

If they complain to you: “I can’t get through, the answering machine is working.” Change your settings or turn off forwarding completely. To ensure you don't miss a call while you're talking to someone else, turn on Call Waiting. In this case, when the second line is triggered, you will hear short beeps.

The caller constantly hears a busy signal.

Turn off mobile internet and synchronization

If you have checked the forwarding settings and everything is fine there, but the caller always hears a busy signal, turn off mobile Internet and synchronization. This usually occurs in areas where operators use old equipment and there is no LTE connection. Usually the person trying to get through then says: “I can’t reach you, it’s always busy. But as soon as you leave the unfortunate area, the calls go fine.

Technical difficulties

First, let’s give a definition and figure out what “Subscriber is temporarily unavailable” means on Megafon. This voice message appears when a random user makes an outgoing call. It signals that you will not be able to contact your interlocutor at the moment.

Most often, the problem does not depend on people - let’s look at the main parameters of the problem:

Being outside the coverage area. The operator has installed a huge number of towers, but in some places they simply do not exist - remote and small settlements, suburban areas;
Weak base station signal. Sometimes the user may be far from the tower; often the signal is interrupted by bad weather conditions, landscape features and buildings. This problem often occurs in the subway;
The interlocutor has entered airplane mode, which means he is on board the aircraft;
Carrying out technical or preventive maintenance by the operator - sometimes problems can arise due to equipment failure.

What to do if a Megafon subscriber is unavailable, what does this mean? Try to wait a while - most often the connection is restored after a certain period.

Outdated or low quality phone

Outdated phones or low-quality counterfeits often have more communication problems for various reasons. The main one is problems with the firmware, which an ordinary user is unlikely to be able to fix on his own. In addition, older models may have problems with calls if an Internet connection is used.

We have already looked at a similar problem, we recommend reading: The phone is dropping calls.

Coverage problem

Banal communication problems cannot be ruled out: poor coverage areas, densely populated areas, distance from base stations, basements and ground floors, obstacles and interference. These problems will be solved as soon as the user or the subscriber calling him changes his location to a more favorable one for making calls.

Other reasons why there are problems with cellular communications are collected here.

Why is he doing this about the blacklist?

The favorite option of a number of subscribers is “Black List”. But it was not there. If you absolutely need to get through to a person, you can “go around the mountain” and avoid restrictions. Follow the instructions:

Write an SMS and ask to be removed from the emergency situation. Turn on message delivery notifications in advance.
Check if you are in an emergency by calling from another number. If the person decides to answer you, you can find out whether you fell out of favor by accident or on purpose.
21st century, guys! We use Viber, WhatsApp, Telegram, Skype - organize a regular or video call. Online regulars can write or send an audio message even via Instagram direct (if you haven’t been banned there either).

The only thing that cannot be bypassed is the “Flight” or “Do Not Disturb” mode, which turns off all incoming messages and SMS.

Operator network overload

There is such a term as “Network Planning”. It is understood that the operator calculates its equipment with a certain margin to support a certain number of connections. When the reserve is exhausted, dialing becomes a problem. At the same time, the operator will not expand the network in advance, since it does not pay off.

Sometimes the PBX signal becomes very difficult to catch

Therefore, when a large number of people try to make a call at the same time, the network becomes congested. Most often this happens on New Year's holidays. There are other reasons that increase the load on substations. For example, a large new building was recently put into operation nearby. As a result, the substation, which was not designed for such a volume of work, could no longer cope with maintaining communications. This means that then the line will be busy when you call the phone.

Santa Claus with a mobile phone

Some operators set an automatic voice message to notify users when the network is overloaded. However, not everyone does this. Therefore, you only hear short beeps on the handset, or simply experience a connection reset. To cope with this situation, you can continue making calls, or move to another mobile substation.

Network errors

Why, when you call MTS, they say that “this type of communication is not available” - this question worries many. It becomes unclear what the soulless autoinformer meant. In fact, there is nothing unusual in such a response - it is often pronounced as a result of some network errors.

Cellular communication is a kind of organism consisting of many elements. And if an error occurs in some module, subscribers can hear this phrase. The most interesting thing is that the phone of the called interlocutor may be turned on at this moment. There is no need to panic in this case - just try calling later. Sometimes it happens that the error disappears after just a few minutes, allowing you to contact the desired interlocutor. But in general, the likelihood of encountering such an error and hearing the phrase “This type of communication is not available to the subscriber” is extremely low.

Wrong network type

If you only hear short beeps during an outgoing call, the problem may be that the network type is not selected correctly. For example, a call goes through a cell tower that only supports 2G and 3G, but the phone has 4G enabled. You can fix this in the settings by selecting a different preferred network type and trying to make the call again.
