The phone drops the call during a conversation. The phone turns off during a conversation - what should I do? Faulty or damaged SIM card: how to determine

If the phone does not receive calls, the reason may lie in a failure in the network settings or the device as a whole. Let's look at how we can solve this problem.

Method number 1. Selecting the Correct Network Settings

In some cases, choosing the right signal source helps. It is not known for what reasons failures in such settings occur, but they do occur and need to be addressed.

Due to such failures, situations arise when the phone does not accept incoming calls and/or does not ring itself. That is, the call is dropped or other problems occur.

Here's what you need to do:

Go to settings and open the menu there Mobile networks».
Select “Network Operators”.

First, click the “Search for Networks” button. All available ones will appear below. Choose the one you need. You can recognize it by its name.

Attention! If you have two SIM cards, go to the tab of the one that is associated with the problem in question.

If you use 3G, be sure to select the appropriate mode in the “Mobile networks” menu for the SIM card with which the problem is associated. This is done by clicking on the “SIM network mode” item and selecting the desired option from the list that appears.

Clue: 3G is WCDMA. It will be called that way in the menu.

Problem not solved? Try rebooting your phone. If nothing has changed then, you will have to do a reset.

Method number 2. Reset

Important! Before you perform any type of reset, be sure to copy all important data to a flash drive or transfer it to the cloud. In some species they will be removed.

In more detail, you will need to use three types of reset - for network parameters (most likely, the problem is in them), smartphone settings and data.

To do this, follow these steps:

Open settings and go to the “Backup and reset” section.
There, at the very bottom, you will see the three reset options discussed above. First, perform “Reset network settings” (click on this item and confirm the action). Reboot your device.
If nothing has changed, use "Reset settings" and "Reset data". Be sure to reboot after each one.

If after this the smartphone does not receive calls, but rings or vice versa, that is, the problem still occurs, you will have to perform hard reset, that is full reset devices.

Method No. 3. Full device reset

This method differs in that it resets not just settings or data, but the entire operating system. The phone is reset to factory state. After such a procedure, the OS will be completely clean and, of course, there can be no failures in it.

Before performing a hard reset, be sure to ensure that all important information has been copied to a safe place and can be restored at any time.

The full reset procedure itself is described in detail (method 5). It is important to take this procedure extremely responsibly and carry out everything as described in the article. If you do something wrong, the device can be turned into a brick. Therefore, if possible, it is better to take it for repair or have it reset by professionals.

“Why can’t they reach me even though my phone is on” – frequently asked question, which is set by subscribers 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:

SIM card malfunction and/or damage;
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 is 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

The smartphone may stop receiving incoming messages after unsuccessful firmware? 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 proposed methods and tips, but they cannot reach you and the phone is turned on, then most likely we are talking about a deeper breakdown, which can be diagnosed in service center.

Many users encounter a problem when your Android phone or tablet starts acting up. It seems that nothing happened that could cause a malfunction, but it does not work as it should.

For example, the device has problems with the fact that the call is constantly or periodically interrupted or ends on its own. The reason for this may be:

1st: Software glitch- i.e. the problem is a software glitch

2nd: Hardware failure- i.e. the problem is in the hardware (i.e., replacement or restoration of spare parts for the gadget is required)

However, do not rush to get upset - in 90% of cases there are problems call connections smartphone a or Android tablet is to blame software glitch which you can easily fix on your own.

Fixing a software glitch:

Method 1. Quite simple - go to "settings", find there « backup and reset", in which you choose full reset settings with deletion of all data. Be careful, using this method is often effective, but it entails deleting all photos, contacts, passwords, music, games, videos and, in general, all information stored on your smartphone e or tablet e. Therefore, first save everything you need by connecting the gadget to your computer. If this method does not suit you, or if after this the problem is not resolved, see Method 2.

Method 2.

Based on solving problems with communication and network reception phone number and tablets based on Android by introducing additional software. Utilities that control all processes inside gadgets. Today, there are quite a lot of them, however, the fewer functions an application contains, the more effective it is, as a rule. The best way to monitor system functions, corrects, and correct all possible settings and synchronization errors is a small, easy-to-use, free utility for Android-based devices. You can download the application from Google Play and see its additional options in the description. After installing the application, all that remains is to launch it. Further, in principle, nothing more is required from you. The application will take full control of the device's functions. (By the way, among other things, the gadget will begin to charge 20% faster, and its performance will also increase significantly, which will affect the loading speed and operation of all applications, games, and the system as a whole. On average, after scanning, the system runs at 50% faster.)
Method 3.

Changing the device software, or as it is also called "re firmware ". This method, as a rule, requires certain skills and can be solved by contacting the Service Center. To carry out this task yourself, you need to contact the website of the manufacturer of your device, download the utilities necessary for flashing the firmware and the firmware itself, and then reinstall it on your gadget.

If none of the methods brings results, unfortunately, you will have to contact the Service Center for repairing your tablet a or smartphone a.

The conversation (call) is interrupted when calling from a smartphone or Android tablet.

Reasons for turning off the phone during a conversation

Shutdown may be caused by the so-called protection mechanism, which is activated in order to prevent a more serious problem with the device components.
The reason for the gadget turning off may be a failure related to both software device, as well as its technical part.
This can also happen as a result of installing a new and incorrectly working firmware version.
The phone turning off during a conversation can also be caused by mechanical damage that was caused earlier: the device was dropped or water got into it, or contacts became clogged with dust.
It also happens that the charge control indicator shows a false battery charge level during a call, i.e. a little (or even a lot) more than it actually is.

What to do if your phone goes off

First, you still need to try to reboot the device, or better yet, remove the battery (if the device has one), turn on the phone again and make the call again.
Sometimes it helps to completely restore the phone battery, or even in particularly difficult cases, replacing the original battery, which wears out over time and may well be the reason why it turns off during a conversation mobile device.
You can check it like this: If while the phone is charging, it does not turn off during a conversation, then the problem is most likely a faulty battery.
If the problem recurs, you need to take the phone to a specialist who will diagnose it and determine the cause of the breakdown. The service center will help eliminate the consequences mechanical damage, they will solder the components or warm up the mobile phone chip, check the battery indicator or reflash the device.

As a conclusion, I would like to say that if a forced reboot and full charging of the battery did not help, it is better to seek help from professionals rather than try to solve something at home, because this can only cause harm and aggravate the problem.
