More and more tablets are equipped with GSM or 3G modules, giving them the opportunity to access the network anytime, anywhere, and not just within Wi-Fi coverage. However, with the advent of SIM card slots in tablet computers, a rather typical problem arose: the tablet does not see the SIM card.

When the software is to blame

Gadget software can also be the reason for the lack of Internet. For example, if after that the network suddenly disappeared, then, with a high degree of probability, the downloaded program was the cause. Just try to remove it.

And sometimes the user’s carelessness is to blame: they accidentally activated the “Airplane” or “Standalone” mode. In this case, you need to check in the device settings that mobile networks are turned on and data transfer is allowed. There, look to see if priority is indicated: in this case, the mobile Internet may also not work, despite the card being identified.

Another reason could be a system firmware failure. In this case, a hard reset will probably help or, in more severe cases, (remember that if you completely reset the user settings, all information on the tablet will be lost, so it’s worth making a backup copy first).

A common situation among people is when the device sees the SIM card, but does not connect to the mobile network. Most likely, the settings for mobile networks are set to parameters for native Chinese operators. You need to indicate your mobile operator there or, if it is not in the list and is not found in the search, manually set the APN and other parameters necessary for connection (you can find out on the operator’s website, in a communication store, or by calling technical support).

Let's sum it up

So, what should you do if your tablet says “no SIM card”? Here's a short algorithm:

  • check whether the “Airplane” or “Standalone” mode is activated;
  • if the Internet stops working after installing new applications, remove them;
  • check mobile network settings;
  • check the SIM card on another device (tablet or smartphone);
  • if everything is fine with the card, check the SIM reader connector using another SIM card (preferably from a different operator) - take the tablet to a service center to replace the slot and cable;
  • if the connector works and sees a card from another operator, replace your SIM at a communication store;
  • if the network does not appear with the new card, do a hard reset or;
  • If all of the above did not help, go directly to the service center.

We hope that thanks to these tips, you will no longer have to scratch your head in confusion when the connection is disconnected and you will be able to solve the problem yourself in most cases.

Some tablet models are equipped with a SIM card slot, which allows the owner not only to connect to the Internet via 3G/4G technologies, but also to call landline/mobile phones. If you do not know how to install a SIM card correctly, then read the information published below. The article will also provide solutions to some problems associated with the use of a SIM card.

How to install a SIM card?

First of all, you need to carefully study the instructions for the tablet and find an item describing the type of SIM card that this device supports. Some models can only install microSIM cards, while others support standard SIM cards.

General algorithm for installing a SIM card:

  1. Turn off the power to the device.
  2. Open the SIM card slot (by pressing or using a special paper clip) and pull out the tray.
  3. Install the SIM card so that the operator logo faces up and the contacts face toward the back of the device.
  4. Place the tray in place and turn on the tablet.

If everything is done correctly, the device should connect to the network and you can go online or make calls.

Important! In some models, instead of a tray, there may be a connector on the back of the tablet, for example, as in the Lenovo Yoga Tab 8, so installing the SIM card in this case will be carried out differently.

How to make microSim?

In order to turn a standard SIM card into a microSim, you simply need to cut it exactly to the size of 15x12 mm.

You can make a smaller version of a SIM card yourself, but if you are not confident in your abilities, then it is better to buy it at the service center of a mobile operator.

The tablet does not see the SIM card

If, after installing the Sim card, the Lenovo tablet does not detect it, then the problem is either with it or with the device. Here is a list of the main problems:

  • SIM card is not active. You need to try installing another SIM card, if it is read normally, then you need to replace the old SIM card.
  • The contacts on the tablet are damaged. In this case, the device will not be able to read information and will need to be taken in for repair.
  • Some models have default carriers and the tablet will not work with others. You must manually set the operator. You may need to reflash the device.

Conclusion:

Installing a SIM card into a tablet is quite simple, but you need to act carefully. If the tablet does not see the SIM card, then you can try to solve the problem yourself, based on the recommendations given in the article or, if necessary, use the services of a service center.

Tablet computers, which are becoming increasingly popular among mobile and other devices, are primarily created by development companies to satisfy the user’s need for web surfing. Naturally, in addition to this, they have a large number of capabilities, are able to satisfy the most diverse desires of their owners in the field of games and entertainment, and can perform the functions of many other mobile gadgets, such as phones, navigators, and media players. You can set up the Internet on a tablet in different ways, but users are often interested in the question: how to set up a tablet to access the Internet via a SIM card?

This type of connection, compared to others, is considered the most difficult and complex, but, nevertheless, is popular among Internet surfers. Regarding options such as setting up the Internet using Wi-Fi or using 3G modems, this method has both advantages and disadvantages. And also not the least role in this matter is played by the telecom operator chosen by the owner of the device.

Using a SIM card in a tablet

Connection technology

Connection procedure

Connecting to the Internet via a SIM card is based on the same principle as when working with mobile phones. A SIM card of any telecom operator is inserted into the gadget into the appropriate slot.

It is important to make sure that mobile Internet is connected to the SIM card, and that your account is topped up. To check your account, you can call the call center of your mobile operator.

Wireless network settings window

Many telecom operators immediately send SMS messages with Internet settings. But, besides this, all these instructions can be found on the official websites of telecom operators. Almost all of them look the same - you need to register an access point. For example, it can be done like this:

  • APN (access point): internet.life.com.by.

Setting up an access point

In the window you must enter the APN connection data; they depend on the operator the user has chosen. In this case, you can enter any name for the card. For example, this data must be entered for the most popular operators:

  • APN: internet.mts.ru
  • Username: mts
  • Password: mts
  • APN: internet.beeline.ru
  • Username: Ivan
  • Password: 123456
  • APN: megafon
  • Username: Supermen
  • Password: Supermen123
  • APN: internet.tele2.ru
  • Username: Not needed
  • Password: Not needed.

Possible connection problems

The first option that should immediately be considered is the correct operation of the SIM card itself. That is, the owner of the tablet device needs to make sure that the card works correctly and is active. To do this, you can do the following:

  • Install a SIM card in some other device to check the location of the network
  • If another device has mobile Internet, you need to track its operation with this particular card
  • Check with your mobile operator that the Internet is actually connected to the card and there are funds in your account.

SIM cards from different mobile operators

If everything is in order with these points, then the user must make sure that he installed the card correctly in the slot. For successful installation you need to follow some rules:

  • When installing the card, refer to the diagram located next to the slot or the instructions for the tablet
  • It is important to keep in mind that on most tablets the SIM card is inserted all the way, and you can hear a soft click
  • Regardless of the success of installing the card, be sure to restart your gadget, perhaps only then will it detect it.

Installing a SIM card in a tablet device

If these steps do not help, it’s a good idea to make sure that the device on which you need to configure Internet access has a built-in 3G module. After this, you can try the above settings again.

It is important to know that if you cannot set up the Internet after everything, then the owner of the device needs to seek help from a sales consultant who helped him in this choice.

Fast and expensive 3G

Using 3G communication is convenient, especially since the 3G network covers much more coverage than Wi-Fi, the use of which is not possible everywhere.

Regularly, all well-known mobile operators provide their customers with various convenient offers and tariffs for communication services, including wireless access to the Internet. The “Internet for Tablet Devices” service is even included in a separate category. More and more users are choosing this particular Internet option for a tablet, because... it does not need constant contact with a power source. This means there is no need to constantly carry cords or cables to connect the tablet to the network.

Tariff plans for mobile devices

3G communication has recently enjoyed increasing success among users of tablet gadgets, due to the fact that it is capable of providing a stable connection and decent speed. 3G will work perfectly even in a moving car or train. On the territory of the Russian Federation, 3G coverage service is provided by Yota, a wireless Internet provider. A huge number of towers in all cities provide good coverage, but, unfortunately, only in cities and their closest suburbs. As soon as the user and his device travel several kilometers from the city, the connection may be interrupted.

To use 3G Internet, the tablet must have a specially built-in module for this purpose. Typically, all top configurations have two solutions - with and without 3G. The price difference between them can reach several thousand rubles, it depends on the developer. To this you can add communication costs, which can vary from several hundred to one and a half thousand rubles, depending on what tariff the user chooses for his device.

Mobile Internet

Most tablet models have a module for a SIM card, and you can use it for its intended purpose. In this situation, the tablet is used as a phone, but you can use the Internet service only with the help of one operator.

Using mobile internet on a tablet

It also has its positive and negative sides. The towers of the selected telecom operator will be located throughout the country and even in hard-to-reach places you can indulge in web surfing. But a lot of money can be spent on this pleasure. The main tariffs are reduced to the following figures: 1 Megabyte of traffic – 1 ruble. With such a pricing policy, it will be difficult for the user not to limit himself on the mobile Internet. But still, this is a good solution for a tablet gadget.

Video instructions for setting up network access

Owners of tablets can use two options: Wi-Fi or mobile Internet. The latter is convenient because the network can be used everywhere. In addition, it is possible. In the material below we will tell you how to insert a SIM card into your tablet, and what to do if the device does not detect it.

Currently, equipment manufacturers equip devices with slots for different SIM formats. There are three types in total.

  1. Mini Sim usually used in old devices or in inexpensive equipment from brands Oysters, Irbis, Digma and the like. This is a standard size of 25*11 mm.
  2. Micro Sim- more modern look. Initially used in Apple technology, in particular, iPhone 4. Later, other manufacturers switched to this format. Size – 15*12 mm.
  3. Nano Sim- the newest format. Size – 12*5 mm. Here the entire card is a chip with minimal plastic frames. The first company to use this format was Apple in the iPhone. Today, the vast majority of modern models work with this type.

Before inserting a SIM card into the tablet, you need to make sure that its size matches the supported format. You can find it out from documentation for the device. If the card is old, then it can be cut using a special device. You should not do this with ordinary scissors, as there is a possibility of damaging the chip.

Advice! If there is a cell phone store of the required operator nearby, they will issue you a SIM card with a suitable standard for free.

If the card is purchased for the first time, it is universal - you just need to squeeze your format out of the plastic shell. When a small card is available, and the connector is designed for a large one, then it is best buy an adapter for all options.

Installing a SIM card

Important! To install a SIM card in the tablet, it must be turned off. Some devices can operate in hot mode, that is, they will detect it without turning it off, but most often the tablet does not see the SIM card without rebooting.

After turning off, you need to find a place for the Sim. Options may vary. Modern Huawei tablets it is inserted into a special slot. To open it, you need to use the small paper clip included in the kit. The carriage is pulled out of the tablet and the card is placed on it. Regardless of the manufacturer, the appearance of the SIM card is the same - rectangular in shape with a cropped corner. Essentially, it is difficult to place the card on the carriage incorrectly, since there is only one position in which it will fit.

The second option is an open slot. This connector is installed in Asus technology.

Here the Sim is simply inserted into the housing. In order to correctly insert a SIM card into the tablet, you need to look at the icon next to the slot. It shows which side you need to place it in the device. When installed correctly, a click will be heard. To remove the card, you need to lightly press on it with your fingernail - it will pop out, as if pushed out by a spring.

The third option is that the slot is closed with a plastic plug. In this case, there will be a small gap on it, which can be easily picked up with a fingernail. In this case, the installation side of the SIM card will again be indicated on the case. This type of slot is found on tablets Samsung company.

The last option is a removable cover. Often owners Prestigio and Digma They are wondering where the SIM card is inserted in the tablet. These brands are one of the few that allow the use of two cards at the same time. To install the device, you must turn it over. At the top of the device there is a removable panel of small width. In the central part above the camera there is a gap that should be picked up with a fingernail. After removing the cover, the user will see space for SIM and microSD. In this case, the card is placed with the chip inside, the cut corner should be at the top.

There are no other places for placing SIM cards in tablet computers. If the question of where the SIM card is inserted in the tablet remains unresolved, then you need to refer to the equipment documentation. There are instructions on where and how to install.

Most often, after installing the card and rebooting the device, it will automatically detect the SIM and start working. When you install it for the first time, you receive an SMS with the settings on your tablet; you need to open and save them. If you haven’t received the SMS, calling the hotline will help. In some cases, the tablet will have to configure it yourself. To do this, go to the settings and find the “mobile network settings” item. Next, open “access points” and create a new point.

An important point when creating a point is to correctly register the address at which the device will connect to the network. This item is called APN. Different operators have different addresses, so the correct option for setting up can be found on the operator’s website.

The address usually looks like this: internet.tele2.ru. In the case of Tele2, you do not need to set the access point name and password. Megafon and MTS may provide them, so in order not to make a mistake, you need to look for information on the official website or contact the salon.

Problems with the SIM card

What to do if the tablet does not see the SIM card? In this situation, there may be several options.

So, to check all the reasons why the equipment does not read the SIM card, we perform a simple sequence of actions:

  • check that the card is installed correctly;
  • check if the “airplane” mode is disabled;
  • if the Internet stops working after installing new software, then it should be removed;
  • if only the Internet does not work, then check the settings;
  • check the SIM in another device;
  • check the connector using another card;
  • do a system reset;
  • If all else fails, then we go to the service center.

Important point! There is no need to try to repair the SIM card or its connector yourself. Some users try to clean the chip and contacts with alcohol and a cotton swab and perform other incorrect actions. This will not help, but will only make the problem worse. If none of the above helps, then it is better to contact a specialist.

Moreover, we will talk in detail about how the SIM card in the tablet is changed.

First, let's look at one important point. It concerns which SIM cards can be installed in the tablet. After all, each device has a special slot designed for a specific type of SIM card.

It turns out that there are devices into which only SIMs of standard sizes are connected. True, there are fewer and fewer of them. Such gadgets include old tablet models from manufacturers such as Prestige, Irbis, Digma and many others. etc.

At the same time, the slots of many other devices are designed only for micro-sim. This is iPad 2, 3, 4 and most Android tablets - Samsung Galaxy Tab, Asus Phonepad, almost all models from Lenovo and many others. etc.

Moreover, do not forget that there are also tablets with slots for mini-sim and nano-sim. For example, these are the popular iPad Mini and Air devices all over the world.

Therefore, before connecting a SIM card, you need to study the characteristics of the tablet. They will definitely indicate which SIM standard the device supports. Also, this information may be contained next to the connector itself into which the SIM card is inserted.

What to do if the SIM card does not fit into the tablet? If it is slightly larger than necessary, then you can try trimming it. Thus, adjusting it to the required parameters. However, the easiest way is to go to a mobile phone store, where they will change your SIM card and give you one that matches your device.

How to insert correctlysim card into tablet?

We figured out that there are different SIM cards. So now let's move on to the next one. Let's talk about how to insert a SIM card into a tablet:

  1. First of all, turn off the device. Then place it on a flat surface with the display facing down. You can lay down a towel or some kind of fabric so as not to scratch the front of the gadget.
  2. Most tablet models have a SIM card slot on the side (sometimes on the back cover). It can be covered with a special flap, which needs to be moved or pulled out by prying it with a finger, nail or other thin object. On some devices, you can only get to the SIM card slot by pressing a paper clip into a special hole. There are also models where you just need to press the lid and release. After which the SIM tray protrudes outward from the connector
  3. If you can’t pull out the tray, you can use a needle or tweezers. Just be careful not to damage the device.
  4. When you get to the tray, you need to install a SIM card into it. This is done quite simply. Moreover, the holder itself has the shape of a SIM card with a beveled corner. You can only confuse the side. Therefore, make sure that the contact part of the SIM card is turned up and directed towards the back panel, and not towards the display. Sometimes there is a hint on the tray itself on how to correctly position the SIM card.
  5. Next, insert the SIM tray into a special slot. Most often, a little pressure is required to ensure that it locks securely. In this case, much effort is not required, otherwise the fasteners or the holder itself may break.
  6. We try to turn on the tablet. If everything was done correctly, the device will recognize the SIM card, and then give the user the ability to make calls and provide him with Internet access.
  7. However, it also happens that the tablet does not see the SIM card. Most often the reason for this is incorrect installation. Pull out the tray again and make sure that the SIM card is securely fixed and that it does not stick out or fall through. Pay attention to whether you placed it on the correct side in the holder.

How to remove a SIM card from a tablet?

Sometimes it is necessary to carry out the reverse procedure. What should you know about her? Essentially, if the SIM card was installed correctly, then removing it from the tablet will not be difficult. You just need to repeat all the steps described above in reverse order. But if an error was made during installation of the SIM card into the tablet (for example, it was placed on the wrong side), then problems may arise.

In addition, sometimes the latches of the tray itself break. Or on some tablets, due to the rather large connector, the SIM card falls deep inside. What to do in this case? Try to carefully pry the SIM card or the part itself holding it with tweezers. If nothing works, then it is best to contact a service center.

Do not try to force the SIM card out of the tablet. Do not pick with a screwdriver or sharp object. So, you can cause mechanical damage to the device, which will put the gadget out of action for a long time.

What to do if the tablet does not see the SIM card?

It also happens that even after the SIM card is installed correctly in the tablet, the device does not react to it in any way. That is, he simply does not see the SIM card. There are many reasons for this problem:

  1. The SIM card itself is blocked. For example, it has not been used for more than six months. In this case, you should contact your operator.
  2. The connector contacts are damaged. This happens both with expensive tablets (from Samsung, Apple) and with budget models (from manufacturers such as Dexp, Prestigio, Alcatel, etc.). Only a service center can help.
  3. Software problems. For example, old firmware on Android often results in the SIM card being inactive. What can be done? Of course, update the OS.
  4. Symbol wear cards. For some reason, many people forget that a SIM card cannot work forever. In addition, with active use, its contacts quickly wear out. This problem can be solved by visiting the telecom operator and replacing the old SIM with a new one.
  5. Inactive network. Some models of Chinese tablets have restrictions that allow you to use only SIM cards from a particular operator. In this case, you will have to seriously tinker with the settings. It may be possible to register the desired telecom operator and activate the network.
