A smartphone or tablet on the Android platform does not dial numbers, does not ring, does not call, nothing happens after dialing the number. What to do and how to fix it.

Many smartphone users encounter this problem when the phone does not accept incoming calls. There are many reasons why this can happen, ranging from a banal software failure to a hardware failure. Today I would like to talk in more detail about the most common reasons why incoming calls are not accepted. Well, and, of course, they will be given useful tips for troubleshooting. Well, let's get straight to the point!

Software glitch

One of the most common reasons why the phone does not accept incoming calls is a malfunction operating system. This is quite a common occurrence, so there is nothing special about it. In general, failures and disruptions in the operation of the OS can be caused primarily by not very good firmware or poor system optimization. As a rule, cheaper phones are from not very famous brands are more often susceptible to this “phenomenon”.

To correct this problem maybe two different ways. The first one, which is also the simplest, is to reboot the phone. You can even simply remove the battery for 10 seconds, then insert it back and turn on the device. In most cases this decision helps.

The second method is to reset to factory settings. If the first solution did not help, it means that the failure occurred at a more global level, and a simple reboot will not fix it. In this case, resetting the settings to their original state helps a lot. You can perform this procedure through the device settings.

Airplane mode

The second reason why the phone does not accept incoming calls is airplane mode. Many users like to use the Airplane Mode function so that no one will disturb them for some time. But, as practice shows, a very large percentage forgets to turn it off after this function, as a result of which they do not receive incoming calls.

The solution to this problem is incredibly simple - you just need to disable this function. This can be done either through the status bar or, as it is also called, the “curtain”. You can also disable “Flight” through the settings in the “Networks and Connections” section (on different phones, this section may be called differently). “Airplane mode” is also disabled through the shutdown menu, which is activated when you hold down the power/lock button.

Incorrect network detection

The next reason why the phone does not accept incoming calls is incorrect network detection. Usually the phone automatically detects the network on its own mobile operator, but sometimes malfunctions occur, as a result of which the device switches to the wrong frequency.

In order to fix this problem, you should follow 2 simple steps:

  1. Go to settings and go to the “SIM cards and networks” menu.
  2. Next, you need to select the “Mobile networks” section and set the definition there either to auto mode, or search and select the required network according to your mobile operator.

Radio module malfunction

The next reason why the phone does not receive incoming calls is a faulty radio module. Unfortunately, nothing can be done about this. Often, communication modules in devices fail. This can happen due to manufacturing defects, frequent falls of the device, moisture getting inside, etc. The problem can only be corrected in one way - by replacing the module with a new one.

Antivirus for Samsung

Well, at the end there is a small point dedicated to Samsung smartphones. Very often, many owners complain that their Samsung phone does not receive incoming calls. This happens not only because of the above reasons, but also because of another, separate one, which concerns only devices of this brand. The fact is that if you install Dr. antivirus. Web on a Samsung smartphone, the application automatically blocks most of the numbers from which incoming calls will not be received.

There are two ways to fix this problem. The first is to remove the antivirus and find a replacement for it. The second is to go to the application settings, go to the “Profile” item and there check the box next to “Receive all calls and SMS”. It's simple!

  • SIM card, number, tariff

      To find out the name and conditions of the current tariff, go to your Personal Account and select the “Tariff” section or dial a free command * 105 * 3 #

Owners of smartphones running Android OS often encounter situations where the basic functionality of the device malfunctions. So, the problem with the lack of connection to the mobile network and rejection of calls can arise for absolutely any subscriber mobile operator. The phone seems to be turned on and working without failures, but other subscribers cannot get through - the operator reports unavailability, and a busy line signal sounds.

It is important to solve the problem as soon as it is identified, otherwise there is a possibility of missing an important call.

Causes of the problem:

All the reasons why the phone does not receive calls can be divided into two categories:

  1. failures in the hardware or software of the smartphone,
  2. problems at work cellular network.

Among the most common reasons from the cellular network are:

    Lack of coverage area. Despite the prevalence of mobile networks and the constant development of new communication transmission standards (3G, 4G, 5G), there are still places where the phone simply does not receive the network. Most often, the problem can be encountered in basements, in areas remote from populated areas. Solution to the problem - if the phone does not receive calls or ring, try moving the device in space, controlling the number of network bars on the screen.

    Accidents in mobile networks. If the base station of the mobile operator in whose coverage area you are located is under repair or maintenance, the phone will receive calls every other time. You can wait until the work is completed or connect to another base station by using special utilities for phone.

    Lock mobile number. The operator has the right to block a subscriber if he violates the rules of service, or if there is insufficient amount on the account Money. You can verify that you are blocked by calling the blocked number. Instead of the standard message “subscriber is temporarily unavailable”, the operator will notify about “temporary blocking of the subscriber”. You can find out the reason why the phone does not accept incoming calls from your operator.

Software problems

If third-party or malicious software is installed on the phone, or beta applications that are malfunctioning, the phone will drop incoming calls and other subscribers will not be able to get through.

Solution to the problem:

1. all suspicious applications from your smartphone.

2. Install on your phone, scan the device for viruses.

3. Remove blacklists or check the settings of blockers (such as Antinuisance for Android, Mr. Number, Should I Answer, etc.)

4. As a last resort, you can do it (keep in mind that when resetting, all personal data and downloaded files will be deleted).

Hardware causes of malfunction

Mobile Internet included

Quite a lot of smartphone users are faced with the fact that they cannot get through to them due to the activated mobile Internet function on the smartphone (most often due to connection to 2G networks). Solution:

If the phone does not accept incoming calls, these standards will allow you to simultaneously receive calls from other subscribers and surf the Internet.

Two SIM cards in a smartphone

This problem is typical for outdated phones, where there is only one module for receiving a radio signal. Despite two slots for SIM cards, while one card is online, the other is simply inaccessible. The only solution is to purchase a smartphone with two radio modules.

Problems with the radio module

Owners of absolutely any Android device may encounter this problem. The solution to the problem is to reboot the phone:

  1. Press and hold the device's power button for a few seconds;
  2. Wait until the smartphone turns off;
  3. Turn it on again after 10-15 seconds.

Another way is to enable/disable airplane mode through the Android settings or quick access panel.

Faulty SIM card or tray

If the SIM card is faulty, incoming calls will not work on the device. You can detect a breakdown in the following way:

  1. Try inserting the SIM card into another phone.
  2. If it receives signals, then the problem is in the SIM card slot.
  3. If the SIM card is not registered on the network on another device, contact the nearest mobile operator office and ask to replace the SIM card.

Problems with IMEI

If current Phone IMEI does not match the factory one, the smartphone may stop receiving mobile calls from other subscribers. Most often, the problem is encountered by users who independently flash the device from one OS to another.

  1. Determine the current IMEI code of your smartphone by dialing *#06#.
  2. Compare the number on the smartphone screen with the combination on the device box. If the box is missing, you can check the factory IMEI using the image under the device’s battery.
  3. If both codes match, the problem is not with the IMEI. In case of discrepancies in data, please contact service center to restore the device.
