Greetings, friends! Admit it, you bought a tablet for Internet surfing, games and other simple tasks. But, suddenly you need to make a call, and your native smartphone is failing, so it comes to mind to use a tablet. Due to the lack of experience, this was not so easy to do? And the device refuses to see the SIM card. What to do? Let's somehow find out why the tablet doesn't see the SIM card and use the tablet's capabilities to the fullest!

The earliest models of tablet devices were not equipped with a SIM slot. Now things are different. Almost every model, even the most budget one, has one or two cells for mobile chips.

Attention! If you plan to use a laptop computer for calls in the future, make sure there is a connector before purchasing.

The first, most common reason that the tablet does not see the SIM card is that it is inserted incorrectly into the slot. How to insert a SIM card into a tablet? The chip card of any operator must be inserted with the logo facing up. And nothing else! Otherwise, the contacts in the device’s special socket simply will not be able to read information from the SIM card and transmit it to the screen.

Special connectors

Tablets with slots for micro SIM cards are becoming increasingly popular. An example of such tablets is a Samsung device. Apple devices require a special format - sa-SIM cards.

Some latest tablet models, for example, Lenovo, have a “cunning” design of the receiving tray. There is only one there, but it is divided into two sections. The size of the card determines where to insert it. The slot for a smaller SIM is marked with a marking picture. Be careful!

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:

1. SIM card of traditional form factor
2. Stationery knife or scissors
3. Sharpened pencil
4. 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.

For what reasons does the device not see the card?

Have you figured out the format, but the tablet still does not detect or show the SIM card?

There may be several reasons:

• Check the activity and serviceability of the card itself. It may be damaged or out of date. To do this, insert another card into the device. If it appears, buy yourself a new card.
• It's worse if he doesn't find another card. Then the reason is the tablet's operation. Most likely, the contacts in the slot are broken. It is best to find out this at a service center.
• Android OS is not infallible, and maybe a simple flashing will fix the situation. It happens that the software is “naughty” and does not read the card. Or you, accidentally or intentionally, have the “Airplane” mode enabled on your device.
• Installing a new system didn't help? Cheap Chinese tablets may simply not include mobile operators in other countries. Then you need to make the settings manually.

Problems with the mobile operator

It may happen that the tablet has stopped seeing the SIM card of a certain mobile operator. For example, it happens that the tablet does not see the Beeline SIM card, but sees MTS. What should you do in this case? You need to restart your phone again. During automatic signal connection, the code from the card is read and it will find the network.

Another solution to the problem is to try sending SMS from your tablet, then permission to send will be automatically requested. Make a confirmation. This option might work. If none of the methods help, it makes sense to change the card to a new one. Beeline service centers will do this for free.

Bottom line

Do not panic if the SIM card in your tablet does not work immediately after installation.

Try a few simple steps:

1. Carefully inspect your SIM card. It may be greasy, dirty or dusty and may not be read correctly. Carefully clean it of excess debris.
2. Remove and reinsert the chip. Sometimes it just doesn't fit correctly in the tray and the connection doesn't happen. Samsung rarely lets its owner down, but “no-name” models are often equipped with loose slots.
3. Reboot your device. All devices can sometimes act up and should be helped from time to time.
4. The card is a fragile material. Over time, the contacts may simply move away or become worn out. Just change it.

In any case, the SIM card must be handled carefully and transferred from one device to another as little as possible.

I want my advice to be useful to you, and I try to become the best I can. Leave your comments under the article and!

Bye everyone, my dear subscribers! Sincerely, Rostislav Kuzmin.

For some time now, tablets have been equipped with special 3G modems and GSM modules, which has allowed the manufacturer to bring devices of this type to a new level of demand. However, along with new communication capabilities, the above-mentioned tablet devices inherited from their smaller brothers (meaning ordinary cellular devices) a certain predetermination to various kinds of network failures. However, in most cases, the seemingly problematic situation “the tablet does not see the SIM card” has a fairly simple solution. This article will help you understand the reasons that led to the “technical blindness” of the device and understand how you can independently eliminate the identified malfunction. So let's turn on the positive and move on!

Form factor features of starter packs

You will be surprised, but in most cases the reason that the tablet does not see the SIM card is precisely the incorrect positioning of the SIM card itself. If the subscriber GSM chip does not fit into the special slot of the device or unnaturally falls into the bowels of the electronic device, the SIM card may not meet the required standard.

Today, the most common use of SIM cards is the traditional type (MINI SIM). The slightly reduced size of GSM cards belongs to the MICRO SIM type. The NANO SIM standard closes the list. By the way, these are exactly the SIM cards that Apple devices are equipped with.

So, if after installing the starter package you suddenly find that the tablet does not see the SIM card, make sure that the installed SIM meets the technical requirements of the tablet device manufacturer. You may need to purchase a special adapter or carefully trim off the extra millimeters of the plastic frame of the GSM chip. In the context of the above, it becomes clear: the size of the SIM card matters.

“Naughty hands” and the consequences of their owner’s thoughtless haste

There are often cases when an unlucky user tries at all costs to shove or squeeze a SIM card that clearly does not want to go in (for known reasons) into the corresponding housing hole. As you understand, after such an “execution” the device is unlikely to work fully in the future. Usually, excessively applied force and the reluctance of some users to understand the current situation in more detail (the tablet does not see the SIM card) lead to a disastrous result: the internal connectors of the SIM receiver break. In the latter case, the “hurry” cannot avoid specialized repairs. Well, if you take into account the fact that the model is a brand name, then this kind of repair will cost a lot of money.

Chinese "troubles", or Where is my operator?

Sometimes the user does not even know that he has become the owner not of the original device, but of a clone from the Middle Kingdom. It is worth mentioning that recently the stereotype “Chinese means...” has become somewhat outdated. However, the relevance of the consequences still applies to devices whose cost more than corresponds to the concept of “cheap”.

So, it may happen that when you insert a SIM card, your device will not be able to detect the operator, that is, the automatic settings will not work. It’s quite natural that the question will definitely arise in your head: “Why doesn’t the tablet see the SIM card?” The answer to such difficulties could not be simpler: search for active GSM networks manually, and after you specify the desired communication provider, the problem will be resolved.

Software failures and methods for eliminating them

A rather difficult situation is when, for example, a Lenovo tablet does not see a SIM card that is known to be working. What to do in this case?

• Contact the store with a reasoned complaint about a malfunction of the device.
• Check the firmware version yourself for compatibility with your device.
• Uninstall third-party software.
• Perform a hard reset of the device, first saving the necessary data to the memory card.

If there are no positive results, seek help from a specialized workshop. Calm down, the flashing process is a fairly quick and relatively inexpensive procedure for this type of electronics such as a tablet.

Finally

So, we can say the main points of the question: “The tablet does not see the SIM card, what should I do?” You and I have allowed it. However, we should not forget that the cause of unnecessary worry may be the user’s banal inattention. Agree, turning to a specialist for help will make a person look a little stupid after the problem with the SIM card is resolved by simply deactivating the autonomous or “flight” mode. By the way, the priority assigned to Wi-Fi networks by the user can also become a kind of culprit for the inactivity of the GSM chip. And lastly: do not discount the negative impact of the environment. After all, sometimes the question voiced in the article “why the tablet doesn’t see the SIM card” can have a funny and, nevertheless, truthful answer: “Write less SMS in the rain!”

That's all. All the best to you and... protect your gadget from bad weather!

Why do you need a SIM card for a tablet?

This gadget has two key advantages. The first is mobility. The device is light weight and small in size. This makes it easy to carry with you. The second is the ability to access the Internet. Together, these two factors allow you to access various online services at any time and anywhere. But there is one nuance here. Tablet computers are equipped with Wi-Fi modules, i.e., access to the network can only be obtained through certain access points to which the gadget can connect. This could be a home router, a public network in a vehicle or a cafe, i.e., a limited list of places from which it is possible to use Internet services. For greater freedom of access to network resources, you need a SIM card for your tablet. With its help you can connect to or even 4G networks of a cellular operator.

Types

Tablet computers can support MiniSIM or MicroSIM. The first type is SIM cards used in cell phones. Their dimensions are 25x15x0.76 mm, i.e. those used by cellular operators. The second type of SIM cards is less known. They are 15x12x0.76 mm. It is almost impossible to find them on sale, but they are easy to obtain from MiniSIM. For this you only need scissors.

You can also contact your cellular operator, where this procedure will be performed by a company employee.

Installation and configuration

To use the capabilities of the mobile Internet on your gadget, you must first insert a SIM card into the tablet. To do this, you need to find the appropriate connector. On the case it is usually indicated by a corresponding pictogram in the form of a SIM card. On some models, this slot may be covered with a protective plug. This is done in order to protect it from dust and dirt. Also on the case is usually indicated the method of installing the SIM card into the slot. If there is no such data, then you can try different ways of inserting the chip. There are 4 possible options in total. If the SIM card is installed correctly, it will lock into the slot.

Next, you can test the network. If there is no connection, you should check the OS settings. By default, this is disabled on tablet computers. This is due to the increased power consumption of the modem. After enabling this option, network access should appear.

If the SIM card is not detected

It happens that the gadget does not access the Internet via the mobile network, even if all the parameters required for normal functioning are set in the OS settings, i.e. a situation arises when the tablet “does not see” the SIM card. In this case, several possible faults are possible.

SIM card defect. This problem is quite common. To diagnose it yourself, you need to remove the SIM card and install a known working one from another device instead. If after such manipulations access to the network appears, then you can go to your cellular operator to replace the faulty chip.

2. Modem defect. If the SIM card used for the tablet works normally on other devices, then there is a high probability of a hardware malfunction. In this case, you should contact the service center to replace the failed module.

3. Software malfunction. Sometimes it happens. To fix this problem, you should reflash the device. You can do this yourself by first downloading the required files from the manufacturer’s website, or you can entrust the work to professionals from the service center.

The modern technology market today is overflowing with various devices for communication, communication and access to the Internet. Tablets are constantly being improved, and more and more fashionable new items appear each time. The famous company Apple produces iPad and iPad Mini tablets equipped with 3G and GSM modules, which allows you to make calls with a SIM card inserted in these devices. Other companies are not far behind Apple: Samsung, Asus, Lenovo. Among budget models, including little-known Chinese ones, there are also tablets with a SIM card at quite affordable prices.

The modern variety of tablets sometimes leads to a real stupor. Even if there are special requests, for example, the mandatory presence of a SIM card slot in the tablet, the number of available models is too high. Among all the variety, there are several best options for purchase.

How to insert a SIM card into any tablet

To install a SIM card, you will need to take into account the following sequence:

1. Turn off the device.
2. Place on a flat surface.
3. Open the tray on the back side of the tablet (the corresponding icon is the guide).
4. Insert the SIM card into the tray.
5. Insert tray.
6. Turn on the tablet and check the functionality of the inserted card.

If the SIM card is not inserted from the side, but under the cover, then you need to remove the cover, and after installing the SIM card, put it in place until the owner hears a characteristic click.

Apple iPad Pro

Of course, the first thing that comes to mind is the development from Apple, which is distinguished by its stability. For a long time now, products from this American company have shown themselves to be one of the most stable. This became possible thanks to the MacOS operating system. The cost of the Apple iPad Pro ranges from RUB 46,990.00 to RUB 96,990.00, depending on the model purchased. The price is the only downside.

• design;
• operating system;
• durability;
• the quality of any part of the device;
• Apple stylus support;
• battery (8,827 mAh);
• power (six-core processor at 2360 MHz).

• price.

Galaxy Tab S3 LTE

Galaxy Tab S3 LTE

Unique design and high quality. This is the motto of the Galaxy Tab S3 LTE. The excellent high-contrast screen allows you to view videos and photos in excellent quality. And thanks to four speakers, surround sound is transmitted. And any task will be feasible for the tablet thanks to its “stuffing”: the Snapdragon 820 processor and 4 GB of RAM.

One of several distinctive features of the S3 LTE is the ability to connect the tablet to the keyboard using a POGO connector, which will have to be purchased separately.

As an alternative, you can purchase the younger Galaxy Tab S2 LTE model, which also has the ability to make calls using a SIM card. This will save money and get a good model that will be relevant for most users today.

The downside is the frankly high cost. Because of this parameter, many people choose products from Apple, since a lot depends on operating systems (performance, quality and speed of work, responsiveness, system wear, and so on), which directly affects the comfort of working with the device.

• battery (6,000 mAh);
• the body is made of metal and glass;
• surround sound;
• AMOLED screen;
• Memory;
• autonomy;
• possibility of connecting a keyboard.

• price;
• Android operating system;
• front-camera.

Huawei MediaPad M3 Lite LTE

Huawei MediaPad M3 Lite LTE

Chinese equipment manufacturers are already serious competitors for companies from Korea, America and other representatives of large brands. The reason for the rapid popularization of products from Chinese brands is the price-quality ratio. Phones and tablets are the best in this regard, especially when compared with any other analogue with a big “name”.

The tablet from Huawei shows itself as a serious competitor. A good screen with a diagonal of 8 inches and a resolution of 1920*1200 pixels. Eight-core processes coupled with 3 GB of RAM provide ample opportunities to run the most demanding applications. The cost is 25,000 rubles.

• identical cameras (front and rear – both 8 MP);
• price;
• metal case;
• performance;
• possibility of expanding memory capacity.

• Not the most powerful rear camera.

Huawei MediaPad M5 8 64 GB 3G, LTE

Huawei MediaPad M5 8 64 GB 3G, LTE

This is the older model of the M3 tablet described above. In all its characteristics, the M5 surpasses its predecessor. The screen diagonal is 8.4 inches with a resolution of 2560*1600. High picture quality in 2K resolution will be available thanks to a good screen. And the eight-core processor is responsible for playback here, where each core produces 2.4 GHz, coupled with 4 GB of RAM, any task will be easily accomplished. The cost is 28,000 rubles. The low price is possible due to the fact that this manufacturer, like Xiaomi, adheres to a policy in which every willing buyer can get good quality for relatively little money.

• maximum permissible memory card 256 GB;
• rear camera 13 MP;
• power;
• screen;
• permission.

• battery capacity 5,100 mAh.

The existing disadvantage can be corrected if you purchase a model with a diagonal of 10.8 inches. In this case, the battery capacity will increase to 7,100 mAh. But this will directly affect the price, then the tablet will cost the buyer 36,000 rubles. At the same time, the technical specifications will not be increased, and the processor power will drop altogether (eight cores at 2.1 GHz, instead of 2.4 GHz).

Irbis TW44

One of the most budget top models, which is included here precisely for this indicator. If we consider cheap options if you need to purchase a tablet for making calls from a SIM card, then Irbis will be able to boast the best price-quality ratio. The cost does not exceed 8,500 rubles. And this immediately suggests that the model cannot compete with flagship models.

All characteristics of the model are based on the cost of the device. If the picture quality on the display is satisfactory (at 10.1 inches, the resolution is 1280*800), then the performance of the cameras will cause dissatisfaction among selfie lovers, only 2 megapixels, both front and rear. But the capacious battery will not allow the tablet to quickly discharge. A quad-core processor and 1 GB of RAM will allow you to run most applications without any problems.

• battery (7,000 mAh);
• ability to connect a keyboard;
• value for money;
• CPU;
• screen.

• cameras (2 MP);
• RAM;
• materials used.

SUPRA M84A 4G

It may seem that a model from such a not-so-common manufacturer made the list. But the reason for this is simple: if you need to purchase a tablet that will perform the functions of a phone, without costing a lot of money, it is quite difficult. If you purchase flagships, then any model will satisfy the client, which cannot be said about cheap tablet options. There are many manufacturers here, most of which do not produce the highest quality and cheapest products. It is not for nothing that there is a saying “The miser pays twice.” To prevent this from happening when purchasing a budget tablet, you should pay attention to this particular model.

Based on the cost, which ranges from 4,500 to 5,500 rubles, the model shows excellent performance results. A quad-core processor with 1 GHz and 1 GB of RAM allows you to use standard functions without problems. There will already be difficulties with launching serious applications, since the processor simply will not be able to perform all the necessary calculations. The average screen is 8 inches with a resolution of 1280*800 pixels. Not the best cameras: rear 5 MP and front 2 MP. Best for reading, surfing and watching videos. Another major drawback is the low battery capacity, only 4,000 mAh, which will not allow the device to last even under average loads for one day. In these parameters, this tablet is not even suitable for comparison with leading models.

• price;
• decent screen;
• performance for the price;
• rear camera

• low battery capacity.

Lenovo Tab 4 Plus TB-8704X 64 GB 3G LTE

Lenovo Tab 4 Plus TB-8704X 64 GB 3G LTE

Another representative of compact options, the diameter of which is 8 inches with a resolution of 1920*1200 pixels. The Tab 4 Plus tablet has 2 SIM card slots and a Snapdragon 625 processor, which has a frequency of exactly 2 GHz. 8 cores and 4 GB of RAM make this tablet quite fast and performs almost all tasks of the average user.

The biggest disappointment with the Lenovo purchase may be its autonomy. The low battery capacity (not much more than the Supra M84A) and high performance results in a not very good result. As a result, when using the tablet’s capabilities at full capacity, the charge may not be enough for a couple of hours.

The cost is 19,500 rubles.

• support for two SIM cards;
• high performance;
• light weight;
• design;
• image quality.

• small battery (4,850 mAh);
• front camera 8 MP.

Prestigio Grace 3101 4G, 3G, LTE

Prestigio Grace 3101 4G, 3G, LTE

One of the options for those users who want to get only basic functions from the tablet, while having a large screen. As far as the budget allowed, the engineers implemented a screen with an IPS matrix with a diagonal of 10.1 inches and a resolution of 1280*800 pixels. Weak processor with four cores with a frequency of 1 GHz. But this is partly compensated by the 2 GB RAM.

The cost of the model is 8,000 rubles. The main reason for being included in this top is the impossibility of purchasing a model from Supra in some cities of the country, as an alternative to buying a tablet with a SIM card slot.

• support for two SIM cards;
• battery capacity (6,000 mAh).

• inconvenient speaker placement;
• cameras (front only 0.3 MP);
• autonomy (resources are not spent rationally).

Lenovo Yoga Tab 3 Plus X703L 3G, LTE

Lenovo Yoga Tab 3 Plus X703L 3G, LTE

One of the competitive devices that is worthy of its price. This cost is formed from the combination of good parts: a 2K resolution screen with a diagonal of 10.1 inches, a Snapdragon 652 processor. The user receives a total performance of 1.8 GHz with 8 cores.

An undoubted advantage is the most capacious battery: 9,300 mAh. It's a little disappointing that the maximum SD card size is 128 GB. The cost of Yoga Tab 3 Plus is 25,000 rubles.

• screen;
• ergonomics;
• sound;
• power;
• Wi-Fi module;
• build quality;
• battery (volume is 9,300 mAh).

• the camera is not in the most convenient place;
• heavy (weight is 635 grams).

ASUS ZenPad 10 Z301MFL-1H006A 3G, LTE

ASUS ZenPad 10 Z301MFL-1H006A 3G, LTE

Tablet from the middle price category. Despite this, it has a good screen (10.1 inches 1920*1200 pixels). But problems may arise for users when using ASUS in conditions where high performance is required. Not always 4 cores at 1.45 GHz are capable of realizing the ideas of the device owner. But 3 GB of RAM allows you not to load and work in standard mode without rebooting for a long time. A separate negative side is the cameras, which could be of better quality given the price of the tablet.

The cost of a tablet with a ZenPad 10 call function is 17,000 rubles.

• good battery, despite the small volume (4,900 mAh);
• sound.

• camera;
• low screen sensitivity;
• outdated operating system.

Each of the presented models is designed to find its own client. The right choice will not disappoint any consumer. If someone only needs it, budget models may be suitable, but if you need a device that can easily “digest” the most demanding applications, you will have to pay attention to the flagships from manufacturers Apple, Samsung, Huawei.

Owners of brand new tablets often find it difficult to immediately understand their device. A particularly common problem that occurs on all IT forums is how to remove a SIM card from a tablet or how to insert a SIM card into a tablet. From the outside, everything seems obvious. But in reality there are difficulties with the SIM card slot. The simple tips collected in this article will help you solve them.

Install and connect the SIM card in the tablet

First, you need to determine which SIM card your device supports. Today there are several types of SIM cards for tablets: regular SIM, miniSIM, microSIM and nanoSIM. They differ only in size, and are listed in order of decreasing dimensions. The most common today are microSIM.

Installing a SIM card is sometimes not so easy, in order to understand how to insert a SIM card into the tablet and avoid any problems, use the instructions:

1. Before installing the SIM card, turn off the device and (for convenience) place the tablet on a smooth surface with the display down. Make sure the surface is clean and will not scratch the screen.

2. As a rule, there is a SIM card slot on the bottom or side of the tablet (check the instructions), often it is located next to other slots or buttons. Pay attention to the design of the socket access system; you may need to use a special key-clip that comes with the tablet. How to insert a SIM card into a tablet using this key? There will be a small hole next to the socket; when you press the key into this hole, the SIM card slot will slide out, then you need to place the SIM in the special tray that slides out.

If there is no hole, it’s even clearer how to insert a SIM card into the tablet: just move the slot flap, pull out the SIM card holder, insert the SIM card from the holder up with the contacts.

3. Push in the tray or holder, put the flap in place (if it is not installed automatically when the holder is pushed in), turn on the tablet and check the connection.

If the SIM card was installed correctly, the question of how to remove the SIM card from the tablet should not arise - just perform all the above steps in reverse order. If something went wrong during installation, it will not be so easy to get the SIM; you will have to use tweezers to pick it up and pull it out.

A short video showing how to insert a SIM card into a Samsung GALAXY Tab

Why doesn't the tablet see the SIM card? This is all in the order of things, just like the usual thing when a smartphone sometimes loses contact with the Sim card. It doesn’t matter what kind of tablet you have – a branded one or a Chinese one, all tablets suffer from this problem.

First, let's understand the process...

How to insert a SIM card into a tablet correctly?

The SIM card is connected to a special connector. A prerequisite is that the SIM card must be inserted so that the operator’s logo is facing up.
IMPORTANT! You don’t need to look at the interior, but look at which side you insert the SIM into the tablet. Naturally, if you insert it upside down, the tablet will not see it, and sometimes you can even damage the card.
Most tablet computer models support the standard SIM card form factor. However, there are devices that only accept a special type of card - the so-called Micro-SIM. An example of such tablets is Asus FonePad, Samsung GALAXY Tab, Acer Iconia Tab, Lenovo, etc.

By the way, the Galaxy S8 is gaining more and more popularity. Our reviews section provides a detailed review and comments from the owners of the popular replica.

On the Apple iPad it looks like this:

How to make a micro SIM yourself from a regular card?

For this procedure, you only need a ruler, scissors (a stationery knife) and a pencil or pen. The micro-SIM dimensions should be as follows: 15x12mm.
It is better to cut out a SIM card, of course, with ordinary scissors, but you can also use a stationery knife and a metal ruler.
After you cut out the micro sim, the corners can be slightly processed (smoothed) with fine sandpaper or a file.

Video on how to make a micro SIM card with your own hands:

Be careful. You can damage the SIM card by cutting it out yourself. You do all manipulations at your own peril and risk. If you damage the card chip, you will have to restore it through the operator’s service center.
