Owners of mobile devices and gadgets insert a memory card into a USB drive, mp3 player, or camera. Many devices, starting with the ones listed above, are made so that most people see a SIM card as a type of information storage device like Compact Flash, SD, MMC. All of them are non-volatile. A SIM card is in other words called a “smart card”. It has memory and a small processor. The latter works without power, so you can’t do without a phone. Each card contains a set of small programs. They are provided by the manufacturer. The GSM standard has a minimum set of operations that any SIM card must meet. The latter's behavior includes permission to enter various parts of her memory. Each has 2 “logins” which are called PIN 1 and PIN2. The first gives access to only some functions. In order to use it, it is recommended to have a data cable that works from a computer. In some cases, the phone does not accept the SIM card.

Global failures in the operating system
The operating system may stop working correctly due to reasons such as an unsuccessful software update or the installation of unofficial firmware that has communication bugs. If you use a custom build, go back to stock.
Check for available updates. If a communication bug is widespread, the vendor will quickly release an update. If the failure occurred as a result of errors during the update and the new build did not fix it, do a factory reset. Then the device will probably recognize the SIM card.
- In the device settings, open “System – Advanced” – Reset settings – Delete all data.
- Reread the warning again and start the process.
- When downloading, you need to reconnect your account and restore your data.
Attention! Hard Reset will erase all data from the device (apps, photos, videos, accounts, etc.), so make a backup copy of your data.
If your mobile phone falls into water, falls and is damaged, or the connection stops working after other damage and the manual did not help, contact a repair center so that a professional can diagnose the device, find out why it does not recognize SIM cards and repair the contacts or tray if necessary.
How to activate a SIM card correctly
To start using the services of a cellular communication company, you first need to correctly activate the SIM card. After activation, you will be able to make calls, gain access to the Internet, send various messages and more.
Now, to properly activate the SIM card, follow these instructions:
- The first step is to fill out the form provided by the seller at the Megafon mobile store. By signing an agreement, you automatically agree to the terms and conditions stated in it. Take this point into account. Next, the consultant provides the client with the document in the form of several copies. The document will contain all the important information that can be used in the future if problems arise. Each of the copies is stored both by the user and by the operator himself;
- Now you need to correctly install the SIM card in your smartphone. Firstly, the socket must be correct for the SIM card to fit correctly. To activate the SIM card, you need to turn on your smartphone, since it is with its help that your plan can be implemented. Once the card is activated and you choose your plan, the consultant will give you the opportunity to deposit funds immediately so that you can make calls and also send messages to you and your relatives. It is mandatory to deposit funds into your balance, since by replenishing your account, you determine which tariff will be set for your smartphone.
However, even if you did everything correctly, the SIM card may not work for some reason. In this case, there is no need to panic, since the problem can be solved quite simply. Next we will look at a list of examples why the SIM card does not work.
Cellular problems
Even cellular communications can fail over time, leaving many users unable to make calls. Most likely, if you encounter a similar problem, it is a technical failure with the operator. If this is indeed the case, then you will see that you have no network at all. That is, you will not even be able to make calls if necessary. More information about this can be found on the official website of Megafon.
Lack of SIM registration on the tablet
Why doesn't the tablet see the SIM card? The reasons for the error in registering the subscriber module in a tablet device may coincide with the circumstances of the lack of communication on smartphones:
- The client’s mobile phone breaks down, it becomes inoperable, the device is unable to see the SIM card;
- Damage to the SIM card - external influence, internal malfunction;
- A user of cellular services leaving the coverage area of a mobile operator.
Specialists from the Megafon user service salon will help identify and eliminate the circumstances of the impossibility of registering on the network when a company client contacts you.
Megafon SIM card does not work
Modern cellular communications have reached the highest level. Clients of large companies can use various communications, such as 3G, 4G, 5G. A high level of communication makes it easy to interact with other subscribers, but there are still problems with the operation of mobile devices. While connecting SIM cards to your smartphone, you may encounter the message “SIM card does not work.” To understand how to get rid of this problem, this article was created.
Reasons for lack of Internet
As you know, many modern subscribers use mobile Internet every day. Some users need a high-speed connection for entertainment and a good time. And for some clients, the Internet is needed for work. But what to do if the connection is interrupted and access to the World Wide Web is blocked? What are the reasons for the lack of Internet on Megafon?
In fact, there may be several reasons why the web connection is unavailable:
- incorrect WAP settings of the mobile device or non-working SIM card;
- technical work on the line;
- there is enough money in the subscriber’s account to access the network;
- The “Data transfer” function is turned off on the phone;
- the subscriber has exhausted his Internet limit provided within a particular tariff plan;
- no network coverage.
As you can see, there may be many reasons why there is no interneta on Megafon. However, almost any of them can be eliminated.
Internet does not work on phone or tablet
If the Internet does not work on your Megafon phone or tablet, try to correct the situation as follows:
- Check your account status. To do this, send the system command *100# from your phone. You can also view your balance status through your Personal Account or a similar application. If there is no Web connection due to lack of funds, a simple account replenishment will correct the problem.
- If there is no network, it is also worth checking the remaining traffic on the package. To do this, send the USSD command *558#. You can also find out the rest of the Internet in your personal account. To do this, go to your page, go to the “ section and view the information you need.
- Make sure the Data feature is turned on on your cellular device.
- Perhaps the problem lies in an incorrectly inserted SIM card. To optimize the device's performance, reinsert the SIM card and restart the phone.
- Make sure the Mobile Internet function is enabled on your device. This information can be viewed in your personal account, in the “Services” section. You can also obtain the necessary data by sending a request *105*306#.
- Try moving the SIM card to another cellular device. If the SIM card also does not work on another device, contact the nearest Megafon service center and request a replacement SIM card.
- If the Internet works correctly on another phone, correctly setting up the access point will solve your problem. The algorithm of actions here is as follows:
Go to the “Settings” section, then “Data transfer”, then “Access point” and set the following parameters:
- APN address: internet;
- APN type: default;
- MNC: 02;
- MCC: 250.
Save the settings and reboot the device.
Internet is not available on the modem
What to do if the Internet does not work on Megafon on a modem? If the Internet on your USB device stops working, do the following:
- check your account status and top up the balance if necessary;
- view the balance on the packages. Perhaps the lack of a Web connection is due to the exhaustion of the quota. If necessary, purchase an additional traffic package;
- update your router software and reboot the device;
- check your settings. To do this, go to the modem management program, then select the “Settings” tab and enter the following data:
- if APN is set near “RAS”, change the value to “NDIS”;
- if the access point is located near “NDIS”, change it to “RAS”.
After that, press the “Save” button and try to enable the Web connection.
- check the serviceability of the SIM card. To do this, move it to any mobile device and try to connect to the Internet. If everything works fine on another gadget, contact the sales office and ask to replace the SIM card.
Communication parameters are lost
Sometimes on Android these settings change spontaneously or disappear after updating the firmware. This often leads to a loss of connection. To resolve the issue, do the following:
- Follow the path “Settings – System” – Advanced – Reset settings.”
- Click on "Reset Wi-Fi, mobile data and Bluetooth settings."
- Confirm the operation.
Next, reboot your mobile if this does not happen automatically.
Replacing a SIM card
Incorrect handling and action by the user also creates a lot of trouble. There is no need to think long about why the SIM card has completed its work. Operators will exchange the old card for a new one. This will be free of charge. Here the reason does not play any role. To get a duplicate you need to fill out an application with your operator. To do this, you need to go to a branch or place an order for home delivery, which will be paid. You can also purchase a copy in the store without any problems; it will only take the client a few minutes. Many reasons can create a problem. As a result, the phone will not detect the SIM card.
If your device does not see Sim:
- Open the phone, take the battery, examine the card. It may be that she has moved from the right place. Perhaps the contacts are not touching.
- The SIM card is poorly positioned to the card reader. The device will work if you place folded paper between the battery and the card.
- Dirt - carefully review the contacts. Wipe and clean it thoroughly. Sometimes this is the only reason why the device does not work. A piece of microfiber cloth and an eraser will solve this problem.
- Other device - insert a card into a phone from another operator. If it works, then there is a problem with your card.

Its employees are energetically working on new projects to improve the quality of work. MegaFon provides mobile communications services, access to the World Wide Web and local telephone communications. It operates in 83 regions of our country, as well as in South Ossetia, Abkhazia, and Tajikistan. MegaFon has a wide mobile coverage area. It works in most regions. For the first time, this company introduced the 3 G service. MegaFon is considered the leader in the provision of Internet services, as well as the second in the number of regular subscribers. The company is trying to introduce new services for clients. Sometimes the MegaFon SIM card does not work. This happens in very rare cases. Relatively high-speed Internet, high-quality voice services, and a stable connection are not all the advantages of this company. Let's find out why the MegaFon SIM card does not work:
- Technical work in the company may be one of the reasons. To do this, restart your phone and wait for the second login to the network. This universal procedure must be done often when a failure occurs and MegaFon does not receive the SIM card.
- If this does not help, then it is possible that the company is holding some kind of measures. Therefore, the MegaFon SIM card does not have a network. You can ask other users. Massive absences indicate that there are technical problems or malfunctions on the company’s equipment. Wait half an hour, then turn off the phone and turn it on again.
- Equipment failure - no cell phone is immune from such a problem. If MegaFon SIM does not work, most likely your device has serious cause for concern.
SIM card problems
It is also possible that your SIM card may be damaged. Most often, a similar problem occurs after using a SIM card for some time, but sometimes this can happen several days after purchase. In this case, obvious signs of a problem will be the lack of Internet, a constant problem with access to mobile communications, difficulties when making a call, problems when sending SMS and more.
In this case, you can go to the operator’s office, where the SIM card will be replaced with a newer version. In this case, take your passport with you.
