In most tablet models, manufacturers have built slots for SIM cards. Why? This was done in order to be able to access the Internet from this device not only via a Wi-Fi connection, but also through a mobile network, for example, Tele 2.
Often, users immediately after the purchase of gadgets are faced with a problem: the tablet does not see the SIM card, and there may be several reasons for this. Let us consider in detail each of them in this article.
Hardware Fault
The tablet may not see the SIM card for several reasons, but first we will consider one of the most important - the malfunction of the device itself. Since the sim-reader is a fragile device, with careless use (frequent change of SIM cards, attempts to insert a SIM card by the other side) it can be very easily damaged.
After careless attempts to insert a SIM card into the tablet, the connector, the contacts, or the cable, which is the connector of the slot to the motherboard, may be damaged.
Attention! If this type of failure occurs, there is only one way out - contact the specialists at the service center, since repairs on your own can lead to a complete breakdown of the gadget.
A malfunction of the tablet can also be due to the manufacturer. If you purchased a gadget of Chinese manufacturers of a budget class, and immediately after purchase, your tablet cannot detect a SIM card, 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 the service center.
Important! Famous firms for the production of gadgets do not allow factory marriage.
Damage to the hardware type also includes a malfunction of the GSM communication module. This chip is responsible for communication: calls and messages. The breakdown is not recommended to be corrected by yourself; you should take the faulty device to a service center, where specialists will check the antenna connection and diagnose the power supply.
Before contacting a service center, you need to make sure that your gadget is really faulty. To do this, fully charge the tablet battery, reboot it and do a full reset to factory settings.
Attention! In most cases, defects of this type are found in cheap tablets or dubious build quality.
Software problems
Problems with the tablet software often cause the lack of mobile Internet:
- In most cases, the mobile network disappears on the gadget immediately after installing a new application. To fix this problem, you just need to remove this program from the device.
- Very often, due to the negligence of subscribers, the mobile Internet may disappear if the “On the plane” or “Autonomous” mode was activated. To solve the problem, check the settings of the gadget and disable these features.
- Also, in the absence of a mobile network, a connected Wi-Fi network may be to blame, which interrupts the signal of the mobile operator.
- If the system firmware fails, the mobile network may stop working. To resolve this problem, you should reflash your gadget.
Important! If you decide to reset all the settings of the tablet to the factory settings, it is recommended to backup all the files you need.
Among the 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 eliminate this problem, you must change the name of the mobile operator providing the services to you, and manually enter its parameters.
SIM card issues
If your tablet cannot detect the inserted SIM card, then the cause of the malfunction may be hiding in it, since most new models of these gadgets require a certain size of cards. That is why many users have to cut them. And very often, subscribers are trying to cut the SIM card on their own with ordinary scissors. They are unaware that they can spoil not only the SIM card itself, but also damage the SIM reader's pad. For the process there are specialized stores in which this service is provided completely free of charge.
Also in this case, you need to check the contact pad, which should be intact and without scratches. The presence of even minor scratches, can lead to the fact that the tablet will not be able to identify 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, both independently and 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 when buying a gadget to pay attention to the manufacturer and build quality, as well as better to buy the original tablet, and not a fake.
