Why not call? Why can’t people reach me on the phone, reasons and ways to fix it. Communication module and hardware failures

Quite often in our service center Clients complain that no one can reach them by phone. The reasons for the occurrence of such problems can be different and in such cases it is not always necessary to contact a service center. In this article we will look at the most common possible reasons, why do you no one can call on iPhone.

What to do if no one can get through?

Software settings

So, if no one can get through to you often, you should first check software settings phone. We'll tell you point by point where to look and what to do.

Do Not Disturb Mode. This function Allows you to turn off incoming calls and notifications from all applications on your phone when the iPhone screen is locked. If the "Do not disturb" mode is active, the caller will not hear the connection sound and the call on his part will end, and a notification about a missed call will appear on your iPhone. You can disable the Do Not Disturb function in your phone settings or in the Control Center (crescent icon).
"Show number" function. If it is disabled, you may experience problems receiving incoming calls. You can enable this feature in your iPhone settings: Settings → Phone → Show number.
TTY mode. The TTY feature is intended for users with disabilities hearing If TTY mode is enabled, then the iPhone may experience problems with dialing in both directions (no one can reach you, you have problems with outgoing calls). You can also disable TTY mode in the device settings: Settings -> General -> Universal access -> TTY.
Operating system system errors. In this case, it is impossible to establish the exact cause. If you have problems receiving incoming calls (no one can reach you), try resetting the network settings: Settings -> General -> Reset -> Reset network settings. After the reboot, observe the “behavior” of the phone. Very often reset network settings solves similar problems.

iOS Errors

Resetting the phone settings does not always solve the problem, although the reasons for its occurrence may still be at the level system files and operation of the iOS operating system. If resetting the network settings does not help, you should probably do it after saving all the necessary information. In fact, this means that you need to reinstall operating system and test the phone after that. You can perform the flashing yourself or by contacting us.

Incorrect operation of the SIM card / Operator settings

Also, quite often, problems with incoming calls on an iPhone can be associated with incorrect work SIM cards. To eliminate this, exchange the SIM card for a new one at your dealership or office. mobile operator.

Hardware problems

If all of the above methods do not give results and no one can still reach you, the causes of the problem probably lie in the hardware problems of the iPhone. You won't be able to do this without contacting a service center. If the problem appears regularly and interferes with the full use of the iPhone, come to our service center. After diagnostics, our specialists will identify the true causes of the problem and offer solutions.

MTS subscribers quite often encounter situations when their phone is turned on, but they cannot receive incoming calls. There are quite a few reasons why MTS cannot reach you. Let's look at the most common ones.

Reasons related to your phone

First, let's look at the basic reasons why you may not be receiving incoming calls. It could be:

Phone radio module freezes. If your phone is registered on the network, but incoming calls are not being received, the easiest way to diagnose it is to try calling somewhere yourself. If you see a “connection failure” message instead of ringing tones, you need to restart your phone. For smartphones, a suitable option is to turn on “airplane mode” for 10 seconds.
Alternate operation of telephone radio modules with multiple SIM cards. If your phone supports multiple SIM cards, in most cases the other SIM cards are blocked when one of them is active. Accordingly, while you are talking on one number, it is impossible to reach others.
Phone or SIM card malfunction. In particular, a breakdown may be indicated by the lack of indication of the name of the mobile network and error messages associated with the absence of a SIM card. You can find out what's wrong using a second phone. Try removing the SIM card from your phone and inserting it into another one. If another device registers on the network and receives calls, then the problem is with your device. If the same symptoms appear on another phone, there is a problem with the SIM card or network.
Presence of malware, various filters for incoming calls and other solutions for blocking calls. If configured incorrectly, they can make your number unavailable for incoming calls.

Network-related reasons

The mobile network also does not always work flawlessly, so situations arise in which it is impossible to reach you.

Poor quality of coating. If you are in an area of uncertain signal, it is likely that you will be constantly . Accordingly, they cannot reach you during those periods of time when your phone is not in service.
Repair work or accidents in mobile networks. If you are within service radius base station, which switched to mode Maintenance, the connection may be temporarily lost.
In some cases, with poor radio planning, There are situations when the phone shows a signal level of 100%, but they cannot reach you. In such situations, it may be enough to simply move or restart the phone.
Incoming calls can be missed indoors. If you have descended to underground levels (ground floor or basement), or gone deep into a monolithic building, it is likely that your phone is no longer serviceable.
Simultaneous calls. It’s quite a funny situation when two subscribers are trying to call each other and cannot do this because they are interfering with each other. The reason is that if you dial the number of the person who dials your number, you will be “out of network coverage” for each other.

Therefore, the recipe for dealing with “network” glitches is to reboot the phone, move it and have a little patience. Sometimes in 5-10 minutes all problems are solved by themselves.

Reasons for blocking a number

It is important to listen to what the answering machine says when your number is dialed. If you hear a message that “Subscriber is temporarily unavailable,” this means that the network “does not see” your device. If you hear a message that “Subscriber is temporarily blocked,” this may indicate financial or other reasons for blocking your number by the operator.

The “Do Not Disturb” function is enabled on the subscriber’s device

The Do Not Disturb feature makes your iPhone unavailable for calls from any number, but it can be activated and disabled automatically at specified times (for example, at night), detailed guide How to configure the mode can be found here. When Do Not Disturb mode is active (an icon with a picture of the month appears in the status bar), the iPhone also answers incoming calls with short busy beeps.

Of course, there is always the possibility of missing a really important call, for example, from family and friends. To avoid such situations, you can make an exception for certain subscribers and allow them to dial on an iPhone that is in Do Not Disturb mode. To do this, you need to perform two operations:

1. On the page of the desired subscriber in the Contacts application, click “Add to Favorites”;

2. Go to Settings → Do not disturb → Call Allowance and check the box next to “From favorites”.

Why is it “busy” only on the first call on iPhone?

Another option that, in theory, allows you not to miss an important call in Do Not Disturb mode is called “Repeat calls”; you can enable it in the same menu Settings → Do Not Disturb (see screenshot above). In active mode, the function skips a call to the iPhone if this is the second attempt to call in the last three minutes.

Your number is blocked (blacklisted by the subscriber)

Blocking subscribers using the “Black List” is easy and quick ( detailed instructions information on working with this function can be found here and here), while the marked contacts from the address book can't get through to User's iPhone
, immediately after a call on the handset short busy beeps will sound
. Thus, the “Black List” allows you to solve the problem with specific subscribers, messages and calls from whom you want to completely ignore.

Based on materials from yablyk

The load on mobile operator networks increases every year, resulting in various problems communications. Even now in places with good signal reception it is not always possible to get through. In addition, there are many other factors that can interfere with communication. We will discuss one of these situations further. The subscriber's phone is constantly busy - what does this mean and what are the reasons? We will consider general points that apply to all operators (MTS, Beeline, Tele2, Megafon).

Blacklist and Do Not Disturb mode

Modern devices are capable of emulating any action. A properly configured Black List completely excludes unwanted incoming messages and more.

What can be done to bypass it?

Send SMS. Enable receiving a delivery report, and in the text of the message itself, ask the subscriber to remove the number from the list.
Call from someone else's number. If calls do not go through from your phone, but do from another, then there is a high probability of being included in
Use alternative communication channels: Viber, Skype, WhatsApp. You can write a message, make a voice call or video call.

We should also talk about setting up the Black List. Its flexibility depends on specific model and manufacturer. Many manufacturers include a really large list of features in their products. For example, you can set up groups, allow incoming calls from phone book numbers, block calls from specific subscribers or groups in certain time and much more. Even the arrival of SMS can be turned off. Smartphones can signal “busy”, “subscriber unavailable”, and the device can also pick up and hang up. And much more.

There are modes in the phone settings. Each of them has its own operating scenarios. In particular, when you select the “Do Not Disturb” option, incoming calls may not go through, giving the caller a “busy” or “subscriber unavailable” message, or they may go through, but without signals.

Often, phone owners do not know about activating these functions, or they are turned on, for example, by children. It is recommended to check the network settings, Black list, actions for groups, settings for specific subscribers and operating modes.

SIM card and phone

The possibility of damage cannot be ruled out. As a rule, the owner himself is interested in such a question due to missing important calls. This can be checked quite simply: using another SIM card and another phone.

If the problem is in the SIM card, then you need to go to the branch of the mobile operator and replace it with a new one. Don't forget to take your passport with you. If the problem is with the phone, then the cause may be damage to the card slot or a software failure. This is often observed when flashing the device. Installing an official ROM or visiting a service center will help restore normal communication.

Reasons why you can’t get through to the subscriber

There could be many reasons for this. The most common of them is a malfunction of the cell phone or SIM itself. The mobile phone could have fallen, gotten wet, etc. That's why it stopped working. The SIM card may fail as a result of demagnetization. This can happen if it is many years old, its chip is subject to frequent friction, the phone has several SIM cards installed at once, etc.

The second reason may be problems with the cellular operator's network. You've probably noticed yourself how communications are lost in elevators, basements, and outside the city. To understand why this happens, you need to know how mobile network works.

Cellular network operation diagram

Every mobile phone works on certain frequency. The quality of the cellular connection depends on it. After you press the "call" button on mobile phone, the signal travels a long way: base station, controller, switch, etc. The connection will not be made until the signal is received back.

Communication, in some buildings and far from the city, malfunctions due to the fact that there is a problem on the signal path from your device to the operator’s base station. a large number of obstacles (thickness of the earth, massive walls, etc.).

Additional reasons

You've probably noticed that on major holidays, for example New Year, it is very difficult to reach anyone by phone. This is due to the fact that during this period a lot of calls are made and the switch simply cannot cope with this load.

Cellular communications may be disrupted due to weather conditions. For example, due to heavy rain, snowfall, thunderstorm, hurricane. It also cannot be ruled out mechanical reasons subscriber unavailability. The optical cable may be damaged, the computers at the base station may malfunction, etc.

There is another reason for the subscriber's unavailability. On some tariff plans mobile operators, the call cannot go through due to a negative account balance. You just need to add money and the connection will resume.

There may also be problems with the phone settings. For example, airplane mode may be enabled, redirection to disabled mode may be configured phone number or a subscriber who cannot get through is blacklisted. To fix this problem, simply read the instructions for use. There you will find detailed information, how to enable the necessary settings. Or just go to any communication shop and ask specialists to help you.

How to get rid of the problem

If you cannot reach the subscriber or the signal does not reach you, do not immediately panic and start calling technical support your operator. Try simply rebooting your phone. If this doesn't help, try searching for the network on your device manually.

If attempts to fix the problem on your own do not bring any results, you can contact your mobile operator. Explain everything to him calmly, without unnecessary emotions. If something happened on telephone line As a rule, this does not depend on the human factor. The task of the cellular operator is to provide communication services in such a way that they satisfy the client. Typically, system problems are resolved quickly.

Technical difficulites

As mentioned earlier, mobile connection increases its power, which leads to various failures. Oddly enough, this happens all the time, even though popular operators (MTS, Beeline, Megafon, Tele2) are improving their equipment.

Technical problems are typical for major holidays - for example, New Year. During the chiming clock, everyone wants to exchange congratulations with loved ones, which happens at the same time.

During the holidays, the network of operators may be overloaded

The result is that the network is loaded, and the subscriber hears an annoying phrase in the speaker that the subscriber’s phone is busy and he needs to leave a message after the signal. The only option is to try to call again and again until the “winning attempt”.

“Why can’t they reach me even though my phone is on” – frequently asked question, which is set by subscribers of different operators (MTS, Beeline, Tele2, Megafon). Most often, the caller receives short beeps (busy) or a return message that “The subscriber is temporarily unavailable.” It also happens that when the antenna is full, the call does not go through, a little later only messages arrive notifying about missed calls. Today we will talk about all the sources of failure in which it is impossible to get through.

Reasons for failure of communication with the subscriber

It is impossible to answer this question in advance. It is necessary to comprehensively study all the circumstances on the basis of which conclusions can be drawn. Let us immediately note the most popular reasons:

malfunction and/or damage of the SIM card;
OS damage, firmware malfunctions, software glitches;
incorrect settings of the communication module or other hardware failures;
Operator problems are the most common cause.

What to do if they can’t reach you?

As a rule, the cause is found out by eliminating options. For convenience, let's look at each source of the problem separately. Let's start by studying the SIM card.

Faulty or damaged SIM card: how to determine?

A simple and logical solution would be the following procedure:

Partial malfunction or damage may result in the call being unable to be completed. By inserting the card into another phone, history repeats itself exactly. At the same time, the other SIM card in my native phone works well and without problems. In this case, you just need to contact the communication center and make a request for a replacement SIM card with the same number.

Software failure

Glitches and bugs occur regularly when using the device intensively. Their scale can be determined as follows.

Communication module and hardware failures

To begin with, it’s worth saying that some smartphones with two SIM cards have only one radio module. Accordingly, then only one of the cards will be “online”. If this is not your case, then simply try rebooting the device or entering airplane mode. It helped, but the problem appears regularly? Use a hard reset or reflash the device stock firmware from the office site. Such moments are quite problematic to diagnose:

OS problems

Can a smartphone stop receiving incoming messages after an unsuccessful firmware update? Other malfunctions may also occur. This occurs due to the use of an inappropriate ROM file (usually custom firmware) or version of the radio module. Incompatibility can be resolved by flashing the firmware. If critical damage occurs, you will have to contact service for help.

Failures can also be caused by system updates arriving over the air. Therefore, it may be effective to roll back the operating system to previous version followed by disabling auto-update.

Operator problems

The lack of a quality network is commonplace. Often, in a densely populated area, rather weak equipment is installed that is not able to correctly serve customers. The problem is especially acute during the holidays and affects all popular operators - MTS, Beeline, Tele2, Megafon, etc.
Another option is lack of coverage or repair work. One way or another, the subscriber temporarily leaves the network coverage area. It is quite logical that in this case the signal in the phone is either absent or at a minimum.
The operator can block a subscriber for violations of the rules for using the network (hooliganism, spam, etc.) or in the absence of replenishments for a certain period of time (usually a year). The message from the caller's operator speaks specifically about blocking.

To improve the quality of communication, you can use special software or connected equipment. The software's capabilities are very limited, so this is not about improving communication, but about optimizing it. There are enough programs in the Playmarket that allow you to automatically configure your phone to the desired operating mode - for example, “Quick Settings”.

The connected equipment is selected depending on the distance from the tower and the presence of interference on the line. Some professional systems can actually improve the quality of communication in a small area at a distance of 30-50 km from the tower. It is often used by owners of country houses.
If you find a malfunction after flashing, be sure to check if the Phone IMEI. You can find out by dialing the combination *#06#, and you can compare the code with the number indicated on the box or under the battery. A lost IMEI can be restored - there are many video instructions on this matter.
If they call and you are always busy, turn it off Mobile Internet- fully! And all the synchronization too. Especially if the operator transmits data over a 2G or 3G channel, then it is sometimes impossible to receive calls using the Internet. At least on standard equipment.
There is a possibility that your phone does not allow incoming calls. This can be done in the device itself, for example, in the Mode settings, or through the operator. In the first case, disabling this function or any type of reset helps, and in the second, calling the operator.

Conclusion

In most cases, problems are short-term, regardless of the cause. If you have tried all the suggested methods and tips, but they can’t reach you and your phone is turned on, then, most likely, we are talking about a deeper breakdown, which can be diagnosed at a service center.
