The SIM card is damaged (not detected). What to do

If Android does not see the SIM card, then the problem is most likely in the SIM card itself or a hardware failure of the phone. But the causes of the problem may also lie in the operation of the operating system, especially if the problem arose after an unsuccessful root or the next Android update.

This article is suitable for all brands that produce phones on Android 9/8/7/6: Samsung, HTC, Lenovo, LG, Sony, ZTE, Huawei, Meizu, Fly, Alcatel, Xiaomi, Nokia and others. We are not responsible for your actions.

What can be done

In order to open the program, you must follow the step-by-step instructions:

1. The modem connects to any working USB port on a laptop or computer. The connection drivers are automatically loaded onto the device, and, without fail, the MTS Connect program (or Connect Manager). If in the area where the subscriber is located there is a 3G coverage area (displayed by a special indicator), to access the Internet after starting the program you just need to give the “Connect” command by clicking on the corresponding button, since all the parameters necessary to connect to network are installed in the program by default.
2. If the specified zone is missing or unstable, it is recommended to change the network settings. To do this, select the “Options” section in the menu, then select “Network” - “Network Settings”.
3. Next, the connection type is set to “WCDMA”. In the event that the 3G network coverage is poorly received, either “GSM” is set, and if 3G is completely absent - “3G Priority” or “EDGE/GPRS”.
4. Sometimes it helps to establish a connection to the coverage area of ​​another network using the MTS kit. To start the transition, select the “Profile Management” - “New” section in the “Options” menu, after which all the requested data is entered into the specified lines (in more modern versions of the program, select the “Modem Settings” section).
5. You can use a regular telephone or smartphone as a modem device. To do this, it is connected to a laptop or computer via a data cable, bluetooth or infrared. If necessary, drivers are installed, after which a connection is requested. To configure the connection, select the “Phone/Modem” section in the “Control Panel”, then “Properties”.

↑ Hardware faults

↑ Incompatibility of SIM card and phone

For example, you bought a super modern flagship smartphone and inserted a SIM card into it that you have been using for a very long time. There is a high probability that the device simply will not be able to read such a SIM card. In this case, we simply go to the nearest office of our operator and change the SIM card to a new one (the number will remain the same).

↑ Problem with slot and SIM card contacts

If you accidentally wet your smartphone or it was left in a dusty room for a long time, then perhaps the contacts of the SIM slot and the SIM card itself are simply dirty or oxidized. To fix this, just soak a cotton swab in alcohol and wipe the contacts here and there.

Utility features

The small software component includes a number of functions that can be used during everyday work with the Internet:

1. automatic detection of a wireless modem with subsequent installation of the appropriate drivers;
2. the ability to manually and automatically change operating modes (2G, 3G, LTE);
3. intuitive traffic control in the form of graphs and statements for a certain period of time;
4. system for sending SMS and USSD directly from the program interface (no need to use a mobile phone);
5. voice calls if appropriate equipment is available.

Although the first version of MTS Connect Manager was released several years ago, the program is in active development status and receives timely updates that add both new functionality and control user security.

Common problems

First of all, if you have problems with the network or Bluetooth, check the SIM card, which should be active. Then you need to check it for defects. If you have another tablet available, you need to insert the card into it to find out whether the problem is with it or with your device.

There may be problems with the tablet if Airplane mode is activated. This can be changed by disabling this mode. Find the cause of the problem by checking that the APN and network data settings are correct.

The reasons for iPad malfunction are usually the following:

• problems with software settings
• SIM card malfunction
• mechanical damage to the device
• moisture getting into the tablet

It happens that the iPad writes “No network” not because of a problem in the software, but does not connect due to mechanical damage. If the iPad has been dropped or been in a damp place, this may cause the cable to break, causing the buttons to not turn on or the network connection to start.

How to install MTS Connect Manager on a laptop

The software is freely available and is necessary for stable operation of wireless modems. You can download the utility from the official repositories of the telecommunications operator, or using other authoritative resources. It is recommended to pay attention to the official source, as this guarantees that you will receive the latest version of the software.

• Run the installer file;
• Select the storage path, the operator recommends using the system disk;
• Wait for the installation and configuration of all necessary components to complete;
• Now you can connect the modem and begin further work.

Windows 10 may require you to set it to compatibility mode with earlier versions of the operating system.

1. Disconnect from the World Wide Web and disconnect the modem from the USB port;
2. Uninstall the software using basic Windows tools. To do this, go to Control Panel, select the Programs and Features tab. In the menu that appears, find Connect Manager and click on the delete button;
3. Restart your computer and reinsert the modem into the USB port;
4. Reinstall the software, after which you will be able to use the Internet.

Causes of the problem

There are many problems that, if they occur, can cause a situation related to the gadget, SIM card, or simply be a temporary problem in the telecom operator’s network. However, the question arises of what to do if the Beeline, MTS or MegaFon phone is not registered on the network, because this means that you cannot use the services.

Of course, it is necessary to understand the cause based on when such a problem arose. Let's assume that you have a contract with Beeline, and to connect to communication services you need to register in the operator's available network, but the phone gives an error and indicates that the SIM card is not registered.

The problem may have different causes, depending on how long the number has been in use. If previously there were no problems connecting the number, then it may depend both on the device itself and on the operator. If this is a new number, then the problem is most likely with it or the SIM card.

Let's try to understand this situation, and what does it mean that you are not registered in the Beeline network or another operator?

If there is no registration, the number is not identified by the network, and therefore communication services are not available. The provision of communication services is available only if the SIM card is identified by the operator’s network. The problem can arise for three reasons: an error in the operation of the gadget, SIM card, or in the operator’s network.

With a device, it can be caused by a simple malfunction in the operation of its system, which is especially true for modern smartphones. But the problem with the SIM can be either due to the lack of proper contact with the receiver, or in its full functionality - the SIM may be old, and the contact field has been worn out due to frequent rearrangement.

It is more difficult to independently determine the problem in the operator’s network, since it can be caused by a simple malfunction of equipment on the company’s side. Such situations, although they occur infrequently, do occur.

Connect Manager does not see the MTS modem - what to do?

If the software does not function correctly and the computer does not see the modem, it is necessary to diagnose the software components and equipment. For this:

• make sure there is a positive balance and traffic;
• reinstall Connect Manager and turn off the antivirus;
• try installing the modem in a different USB port. Check if it is detected in the Windows device list;
• reinstall the modem SIM card.

If the above methods do not help, contact a technical support specialist at your telecommunications operator. This can be done by calling a toll-free phone number, or using the form to send a text request through your personal account or mobile application. Formulate your request in advance and indicate the steps taken. You will then be given instructions to connect to the network.

Today we will tell you what to do if your computer says mts modem not detected , as well as problems with modems from other manufacturers.

As you probably understood, we will talk about 3G modems of mobile operators (MTS, Megafon, Yota and others). Sometimes it happens that after prolonged use, suddenly the computer starts to write modem not detected , here are some tips to correct the situation when the computer does not see the USB modem:

- the simplest thing is to try turning off the computer, plug the modem into another USB connector and turn on the computer again. If you are using a USB extension cable, try plugging in the modem without it; sometimes the reason lies in a faulty cable.

- disconnect the modem from the computer - uninstall the program for connecting to the Internet (Megafon Internet, Mts Connect, etc.) - restart the computer - turn on the modem and try to install the program again PS you can read how to remove the program here

— if the modem stops working after the update, then you can try to select a restore point before this update. • press WIN+R • insert rstrui into the window • press enter • select the restore point when you think the modem was working • We wait. If after restoration nothing works, you can go back using the same steps.

How to restore a SIM card

When all possible verification and analysis options indicate that the registration error appears due to an inoperative SIM card, then you should contact the appropriate communication center. Of course, they won’t be able to fix it, but the mobile operator is obliged to replace the damaged element. In this case, the subscriber must take with him the documents for which the old SIM card was issued. If the staff cannot correct the error during registration, then the client will receive a new starter package.

To Beeline

If the problem node turns out to be a SIM card from the Beeline company, then you should first of all contact the hotline at 0611. Employees of the organization are obliged to carefully study the problem that has arisen and take further action. If the result does not meet expectations, then you need to go to the nearest service center. After filling out the application and explaining the problems, the manager will solve the problem or replace the card.

To Megafon

When a communication element falls under a registration error, you need to call the operator at 0500. During the conversation, you should explain in detail the essence of the problem, as well as how and under what circumstances the card stopped functioning. In the worst case, you will have to go to a communication store and purchase a new starter package.

In MTS

The principle of restoring the functionality of a SIM card at MTS is similar. First, you need to call the operator and report the problem that has arisen with the communication element. If the operator cannot take any action, then you will need to contact the nearest office and purchase a new package. What does that require:

1. Visit the service center, having with you your passport, for which a new card will be issued. Next, you should return the inoperative item and fill out the appropriate application.
2. When the manager completes the documents and verifies personal information, the client will find out when and where he can receive a new starter package.

It is noteworthy that MTS replaces broken SIM cards absolutely free of charge. Additionally, the subscriber can assign the old number to himself if the latter remains free. Previously connected options and services will remain fixed on the future package.

In Tele2

In the case of Tele2, things are simpler. The client does not need to call the operator, but should immediately go to the manager at the service center. You must have documents and a deactivated card with you. The company's employees will conduct several tests and identify the cause of the breakdown. If the element is incapacitated, the subscriber will receive a new starter pack for free. As with MTS, the old number can be retained on the new package with all connected services.

After reading the instructions provided, the user will be able to figure out the problem that arises during the registration of a SIM card. In any difficult situation, you should always contact your own mobile communications staff.

The last way to get rid of the “Registration failed” problem is to configure the GSM, WCDMA frequencies

Many modern mobile phones support GSM and WCDMA networks. On some devices, installing GSM operator SIM cards is only possible in one of the SIM card slots. Check your device and its specifications. If everything is correct, and only emergency calls are available on the SIM card and the network registration error is still present, we will try to eliminate it by adjusting the network operating mode. Some phones have network mode settings and you should change "GSM/WCDMA (automatic)" to "GSM only". To do this, go to settings - other networks - mobile networks - network mode and select the GSM only tab. After this, you should restart your phone. Very often, this solution allows you to get rid of problems with registration in the mobile operator’s network.

To be honest, when I had an old Lenovo dual-sim, everything worked fine on it, probably I was just lucky. But the phone itself was so-so. Later, having changed the device to an HTC with support for two SIM cards, everything also worked without problems, although the HTC was on a Lenovo-like MTK platform, but it worked much faster and I liked it because the GPS on it did not glitch, unlike...

So, I'm going off topic. On a fresh Samsung device, I encountered the fact that the SIM card of the second operator refused to register on the network. Trying to select a network manually led to a long, tedious wait for the device to respond, and then I received the message “Registration failed.” I swapped the SIM cards, but nothing changed, I checked the SIM card of the operator that was faulty, but it works in another device. I left one in Samsung - it works. Through trial and error, I found a solution that helped in my case. Perhaps it will help you too.

My main SIM card was in the first slot and worked perfectly. It is chosen as the main one for voice calls, SMS and mobile Internet. Sim 2 was in the second slot. After turning on/off the “Airplane” mode, it was able to register on the network, but after 3-5 minutes it was no longer registered and I could not make calls from it. Since my Samsung did not have a choice of GSM/CDMA mode, I paid attention to the choice of operating mode in the LTE/3G/2G network available for each SIM card. Through trial and error, it turned out that for the first SIM card I set LTE/3G/2G. And for the second I set “Only 2G”. In this case, it registers and works fine. Any other combinations did not help. I hope it helps you too.

After solving the problem, I found out that LTE/3G/2G is a GSM/CDMA mode. The Samsung website states that 2G = GSM, 3G = WCDMA, 4G = LTE and also states that on a smartphone with two SIM cards, one always works only on the 2G network - this is normal operation of the device and cannot be changed! It turns out that the second SIM card could not register on the network because 3G was selected in the settings.

SIM card information

A SIM card is a physical electronic module that allows you to identify a subscriber on the network using a special number. Although e-Sim has already been invented and implemented in some smartphone models, the world is not yet ready to abandon the physical identification medium.

The SIM card has gone through several stages of modernization and you may be familiar with some of these stages by the name of the form factors:

1. Full-size - an outdated look, the size of a plastic bank card.
2. Mini-SIM is a popular format for smartphone models from 2000 to 2010.
3. Micro-SIM has become popular in many smartphones, including Android ones.
4. Nano-SIM - performs the same functions as the Micro form factor, but the edges are trimmed as much as possible for compactness.
5. E-SIM is a chip sealed into the device during its manufacture at the factory.
6. Virtual-SIM – identification using software that transmits a signal through other communication modules (Wi-Fi, Bluetooth) to a SIM card located in another device.

Understanding why the phone does not see the SIM card, you need to understand the interaction chain of the module in the device and access through it to the mobile operator’s network:

1. The SIM card is installed in a special card reader, connector and fixed so that the phone contacts come into contact with the contact pad of the electronic module.
2. Using the GSM module, the phone is registered in the network. If this does not happen automatically when you turn on your smartphone, you need to activate mobile communications in the settings.
3. When a network is detected, an identification mark will appear on the display.
4. If you specify "Searching" or "No network", you may be in a location where there is no coverage area.
5. If there is enough money on your balance for a call, you will be able to make it or “go online”.

There are some nuances that prevent the phone from accepting a SIM card.

IPhone does not see SIM card

The iPhone is a more premium device and is less likely to have problems with “bad contact” of the SIM card, and the latest models with dust and moisture protection according to the IP68 standard prevent oxidation of the contacts even when water gets on the case.

However, mechanical influences cannot be excluded. Impacts to the iPhone can deform the contact pad or tray; the SIM card can simply move or become deformed (break).

But what to do if the phone does not see the SIM card on an undamaged and fully working device?

In addition to the number expiration, there are three more reasons:

1. Outdated iPhone models with problematic Airplane function.
2. Locked iPhones.
3. Network settings are lost.

iPhone with SIM-LOCK

An iPhone with SIM-Lock is a device that can only work with a SIM card from a specific operator. If you install another one in it, the device will not perceive it. Also, without a SIM card from the desired operator, it will be impossible to activate the smartphone.

Such devices are usually made to order for a specific operator, are cheaper, but deprive the owner of the right to choose to switch to another operator. These iPhones are mainly sold in the US and Western European countries.

This must be taken into account when picking up the phone. It is recommended to check the functionality in mobile networks with a new SIM immediately by installing it in the tray and making a call. You can determine whether your iPhone is locked or not:

1. Install a SIM card into the device and turn it on. If “Activation Required” appears on the display, it means the lock is installed.
2. Using the iphoneox.com service. Enter your iPhone's IMEI and check the device status. If Unlocked, then everything is in order, the device can work with all operators.

Airplane mode feature

The iPhone 5 and some variants still have an issue with the Airplane mode feature. This function disables all communication modules, which is useful when you are on an airplane.

Unfortunately, disabling this feature takes some time. That is, for the communication module to work, you need to wait more than a minute. Sometimes the phone needs to reboot.

New models with good hardware have gotten rid of this problem. At least, there were no global alerts about problems with the aircraft regime in this direction.

Enable network in settings

If you are in a network coverage area, check your iPhone settings:

1. Go to "Settings" and select the "Cellular" section.
2. Enable the data transfer function.
3. Reboot your device.

If the network is not detected, you can reset all network settings (including Wi-Fi access points):

1. Go to “Settings” – “General” – “Reset” – “Reset network settings”.
2. Then connect to the access point and open the “Settings” - “General” - “About this device” section.
3. Update your cellular operator settings.
