Not every user knows how to set up a SIM card on a tablet. Many tablet computers are equipped with at least one SIM card. Sometimes situations arise when the tablet does not recognize the SIM card. Manufacturers are gradually expanding the functionality of devices. Modern tablets make it possible to make voice calls and send SMS. Mobile operators are developing new tariffs. SIM card chips are being improved and the speed of mobile Internet is increasing. Why doesn't the SIM card work in the tablet? Today we’ll talk about what needs to be done in such a situation.
The tablet does not see the SIM card, what should I do?
When the tablet does not see the SIM card, the first thing to do is to find the cause of the problem. The problem may periodically remind itself. For example, the network does not connect to the SIM card. Or the Internet does not work - the network was not found.
There are several reasons why SIM cards malfunction:
- operating system failure;
- mechanical damage to electronics;
- careless handling by the user.
The main reasons why the tablet does not see the map:
- a software glitch occurred;
- the SIM card is damaged;
- the operating system was updated incorrectly;
- activation of flight mode;
- no 3G or LTE;
- data transfer disabled;
- poor quality firmware;
- the tablet computer is infected with viruses;
- the connector is broken;
- The communication module burned out.
First of all, the gadget needs to be rebooted. In some cases, such simple actions help solve the problem. Try installing the SIM card in another device. If the SIM card is recognized in another gadget, then the tablet is faulty. The drastic method to solve the problem is to reset to factory settings.
Causes
To begin with, it is worth noting that the situation under consideration has exactly the same reasons and solutions that are provided for a similar problem when using a regular smartphone. This similarity is especially acute on devices from “masters from the Middle Kingdom”, who offer their customers an abundance of built-in modules and functionality for a “meager” price. But such a “cheap vinaigrette” can and will definitely have certain “pitfalls,” since the colossal difference in the market price imposes certain limits on the quality of the final product. Cheap smartphones and tablets almost always lack mandatory preset settings, the presence of which ensures proper operation of the SIM card, and most importantly, the functionality of the network and its actual location/determination. The solution to this issue will be discussed a little later.
A cause-and-effect relationship can also occur as a result of a hardware problem, both on the side of the SIM card itself and on the side of the tablet, for example, the module itself or the SIM slot is faulty. In addition, as many probably know, many mobile operators produce gadgets under their own brand (Beeline, Megafon, MTS), and set certain restrictions on the use of SIM cards from other operators. It’s logical, because who wants to “feed” competitors. This restrictive “sim-lock” function blocks the very possibility of recognizing components, the release of which is not the developer/manufacturer of the device itself, and this is precisely what leads to the situation discussed in this article. And now it’s time to touch on the main questions: “How to fix all this? And is this possible in principle?
What to do if the SIM card does not work?
Check if you installed the card in the slot correctly. It doesn't matter what Tele2 or MTS SIM card you have. You need to insert the SIM card carefully. If you need a different SIM format for full operation, you need to contact a mobile phone store. Don't know where to buy a Yota SIM card for your tablet? On the VsemSimki online store website you will find cards of all formats. What not to do? Try to cut the SIM card yourself. If you do not fit the card correctly, the chip will get stuck in the slot. As a result, the operation of the Sim reader will be disrupted.
If the tablet does not read the card that you cut yourself, you should contact a mobile phone store for help. The SIM card can be replaced while keeping the number. When the tablet does not see the map, it is impossible to use the Internet. If, for example, the Beeline SIM card for the modem does not work, you need to act differently. Check your access point settings. It can be configured if necessary. Information on settings can be found on the official website of your operator or by contacting technical support. If your tablet computer does not read the card, you can use another option. It's worth trying to clean the contacts with an eraser. They are located on the yellow SIM card chip. Very carefully use the tip of the eraser to clean out the recesses of the card. Blow off any remaining eraser and place the card in the slot.
How to make a micro-sim or nano-sim
Mobile operators keep up with the times and sell chip cards with an imprint. What does it mean? This means the presence of special grooves on the plastic part of the card to independently transform it into a micro-SIM card. And this format is supported by most tablets of the latest year.
If your SIM card dates back to the times when phones could only make calls (imagine!), then you can adjust its size yourself.
What you need for this:
- SIM card of traditional form factor
- Stationery knife or scissors
- Sharpened pencil
- Ruler and...PATIENCE!!!
How to proceed? Draw new boundaries on the plastic field with a pencil. The new dimensions must strictly comply with the parameters 15 x 12 mm. Cut one end diagonally and sand the edges with very fine sandpaper. Proceed with extreme caution and take your time.
Remember! Damage to the metal plates on the card will inevitably lead to its damage. Then you will have to restore the card again at the service center of your mobile operator. There is an automatic card cutting service available at a specialty electronics store. They are very inexpensive. If you are not confident in your abilities, you should go there for pruning.
Nano SIM is 0.09 mm thinner than cards of other formats. You can't tell it by eye. But Apple even has smart slots in iPhones - a SIM card cut to fit the format may not fit. Craftsmen from the Internet recommend removing the excess layer with sandpaper. I advise you to make a replacement from your mobile operator. Both Beeline, Megafon and MTS make such replacements at subscriber service centers.
Support 3G and 4G LTE mode
Another simple way is to check the modes. To work in a tablet, the card must support 3G and LTE networks. All SIM cards of the latest generations can support these standards. Therefore, most often the problem of lack of connection occurs on outdated cards. In addition, you need to check the signal level in the place where you want to connect. We go to the official website of the operator. We check the signal according to the coverage area. You can also contact a mobile phone store for help. If necessary, a SIM card with an updated chip will be issued. Do not rush to change Megafon SIM or MTS card. You may be using an outdated device. Therefore, the tablet does not “read” 4G signals. If the gadget does not support this communication format, it needs to be replaced. Alternatively, you can set up 3G.
Checking airplane mode
Airplane mode is available on all modern devices. If you enable the option, all types of received signals will be deactivated. The tablet computer will work autonomously. When airplane mode is turned on, the corresponding icon will be displayed at the top of the screen. To enable or disable the option, go to the quick commands panel. Checking the status of the symbol. Usually the icon is made in the form of an airplane. If the mode is enabled, it must be deactivated. Now try going online again. If the option is enabled, the tablet computer will automatically disconnect from communication lines.
Installing applications
The main applications needed for the main functionality of the tablet are already on it. This is a browser, proprietary software (if offered by the manufacturer), camera shell, photo gallery, phone, messages and much more. To install your programs or games and use your tablet comfortably and correctly, you should launch PlayMarket . Its icon is usually located on the main screen, accessible after downloading.
Before you search for programs, you need to establish an Internet connection. The launched PlayMarket automatically logs into your Google account. The search bar is available to the user. Here you can write both the name of a specific application and wishes. For example, “games of balls”. After searching, the user is presented with a list of available programs. Application icons can be clicked. The user is taken to the program page, where its functionality and purpose are described in detail. Here you can read reviews from people who are already using this software.
To install the program, you need to click on the big green button with the corresponding inscription. The application will download automatically. After the installation process, the Open button becomes available, which is used to launch the program.
Setting up data transfer
Data transfer is needed to access the Internet via 3G and 4G LTE. These signals take a lot of charge from the tablet's battery. Therefore, on some gadgets this function is enabled independently. You can activate the option through the command panel of your tablet computer. The icon resembles an antenna. Data transfer can be configured in the settings menu. We find a category called “Communication and Signals”. Next, look for the “Data transfer” item. Here you need to enable the option. The following problem is typical for Chinese devices. The tablet sees the map, but cannot connect to the network. Let's consider the solution to the issue. By default, the device is configured with the settings of Chinese providers. We set the settings manually. To do this, select the desired cellular operator.
Problems with “Chinese” devices
Currently, many “fake”, non-original tablets are sold in markets and stores. Such devices with the names of world brands are assembled by craftsmen. All their components are of low quality, and the declared parameters are always overestimated. Therefore, it is not surprising that such gadgets sometimes do not detect a SIM card.
If you know that your device is not original and does not see the SIM card, you can enable it yourself.
- To do this, go to the tablet settings,
- then find the menu that says "Network", "Antenna", "Connection"
- "Operators" and so on. This section should include a manual network search.
- Click on it, all available networks should appear, then select your operator from them and connect, your SIM card should work.

Updating the system
Updating the OS is an effective way to eliminate malfunctions and glitches. If the operating system on your tablet has not been updated for a long time, you need to reinstall it. Sometimes, due to software glitches, problems arise with the operation of the SIM card. You can make an update through the gadget settings. As a last resort, we try to reset all settings. Press and hold the volume button and the power button. After the Hard Reset procedure, all information from the tablet will be deleted. Therefore, make a backup copy first.
