A tablet may not see a SIM card for several reasons, but first we’ll look at one of the most important ones - a malfunction of the device itself. Since the SIM reader is a fragile device, it can be very easily damaged if used carelessly (often changing SIM cards, trying to insert a SIM card on the other side).
After careless attempts to insert a SIM card into the tablet, the connector, contacts, or cable, which is the connector of the slot with the motherboard, may be damaged.
Attention! In the event of a breakdown of this type, there is only one way out - contact a service center as the repair on your own can lead to a complete breakdown of the gadget.
A tablet malfunction may also be due to the manufacturer. If you purchased a gadget from Chinese manufacturers of a budget class, and right after the purchase, your tablet will not can detect a SIM card, in this case it is necessary to return the device back to the store and demand replacement. If there is no guarantee for a faulty gadget, then it is better to visit a service center.

Damage to the hardware type also includes a malfunction of the GSM communication module. This chip is responsible for communications: calls and messages. The breakdown is not recommended to be corrected on your own, the faulty device should be taken to a service center where specialists will check the antenna connection and conduct diagnostics of the power circuit.
Before contacting a service center, you need to make sure that your gadget is really defective. To do this, fully charge the tablet’s battery, reboot it and make a full factory reset.
Attention! In most cases, defects of this type are found in cheap tablets or of dubious build quality.
Software Issues
Problems with the tablet software often cause a lack of mobile Internet:
- In most cases, the mobile network disappears on the gadget immediately after installing some new application. To fix this problem, you just need to remove this program from the device.
- Very often, due to the carelessness of the subscribers, the mobile Internet may disappear if the “Airplane” or “Offline” mode has been activated. To fix the problem, check the gadget settings and disable these functions.
- Also, in the absence of a mobile network, the connected Wi-Fi network, which interrupts the signal of the mobile operator, may be to blame.
- If a system firmware failure occurs, then the mobile network may cease to function. To fix 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 that you first back up 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 malfunction, you need to change the name of the mobile operator providing the service 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 hide in it, since most of the new models of these gadgets require a certain size of cards. That is why many users have to crop them. And very often, subscribers try to trim their SIM card with ordinary scissors. They do not suspect that they can spoil not only the SIM card itself, but also damage the contact area of the SIM card reader. For the process, there are specialized stores in which this service is provided 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 can lead to the fact that the tablet will not be able to identify the SIM card.
In conclusion, I want to note that any of the causes of a 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 engage in amateur activity if you are not able to fix it on your own.
Important! We recommend that when buying a gadget pay attention to the manufacturer and build quality, it is also better to buy an original tablet, not a fake.
