Why does the tablet not see the SIM card?

Manufacturers have built-in SIM card slots into most tablet models. Why? This was done so that you could access the Internet from this device not only through a Wi-Fi connection, but also through a mobile network, for example, Tele 2.

Often, users immediately after purchasing gadgets are faced with a problem: the tablet does not see the SIM card, and there may be several reasons for this. Let's look at each of them in detail in this article.

Hardware type fault

The tablet may not see the SIM card for several reasons, but first, let’s look at one of the most important: a malfunction of the device itself. Since the SIM reader is a fragile device, if used carelessly (frequently changing SIM cards, trying to insert a SIM card with the other side), it can be very easily damaged.

After careless attempts to insert a SIM card into the tablet, the connector, contacts or cable, which connects the slot to the motherboard, may be damaged.

Attention! In the event of a breakdown of this type, there is only one way out - contact specialists at a service center, since repairs on your own can lead to a complete breakdown of the gadget.

A tablet malfunction may also be caused by the manufacturer.If you purchased a budget-class gadget from Chinese manufacturers, and immediately after purchase your tablet cannot detect a SIM card, then in this case you need to return the device back to the store and request a replacement. If there is no warranty for a faulty gadget, then it is better to visit a service center.

Important! Famous gadget manufacturing companies do not allow manufacturing defects.

Hardware damage also includes a malfunction of the GSM communication module. This chip is responsible for communications: calls and messages. It is not recommended to fix the breakdown yourself; you should take the faulty device to a service center, where specialists will check the antenna connection and diagnose the power circuit.

Before contacting a service center, you need to make sure that your gadget is really faulty. To do this, fully charge the tablet's battery, reboot it and do a full factory reset.

Attention! In most cases, defects of this type are found in cheap tablets or of questionable build quality.

Software problems

Problems with tablet software often cause a lack of mobile Internet:

1. In most cases, the mobile network disappears on the gadget immediately after installing a new application. To fix this problem, you simply need to remove this program from the device.
2. Very often, due to the inattention of subscribers, the mobile Internet may disappear if the “Airplane” or “Offline” mode was activated. To fix the problem, you should check the gadget settings and disable these functions.
3. Also, the lack of a mobile network may be due to the connected Wi-Fi network, which interrupts the signal of the mobile operator.
4. If the system firmware fails, the mobile network may stop working. To fix this problem, you should reflash your gadget.

Important! If you decide to reset all the tablet settings to factory settings, it is recommended that you first backup the files you need.

Among Chinese-made gadgets, most of them see a SIM card, but do not connect to the mobile Internet. Most likely, the reason lies in the settings of mobile networks, the parameters of which are set for other operators. To resolve this problem, you need to change the name of the mobile operator providing your service and manually enter its parameters.

Problems with the SIM card

If your tablet cannot detect the inserted SIM card, then the cause of the malfunction may be hidden there, since most new models of these gadgets require a certain size of cards. This is why many users have to trim them. And very often subscribers try to cut the SIM card themselves using ordinary scissors. They do not suspect that they can damage not only the SIM card itself, but also damage the contact pad of the SIM reader. There are specialized stores for the process that provide this service completely free of charge.

Also in this case, it is necessary to check the contact pad, which should be intact and without scratches. The presence of even small scratches may result in the tablet not being able to detect the SIM card.

In conclusion, I would like to note that any of the reasons for the problem with the card in the tablet can be completely eliminated either independently or with the help of specialists. The main thing is to determine the true cause of the defect and not to engage in amateur activities if you are not able to correct it on your own.

Important! We recommend that when buying a gadget, pay attention to the manufacturer and build quality, and it is also better to buy an original tablet and not a fake.
