But in any case, besides, when one of them is 3G and the other is 4G, it makes no sense to rearrange SIM cards.
What to do if the phone does not see the second SIM card?
If the problem occurs on a phone with two SIMs (dual SIM), then the cause of the breakdown may be that the SIM card is turned off. This function is present in them in case it is undesirable to use only one of the two SIM cards. In this case, just go to settings and enable the card you need.

In some cases, when you try to turn on the SIM card, the phone freezes for a short time, and then closes the window for turning on the card, without activating it. This may mean that it has been erased Phone IMEI. You can check this in the following way. IN standard application“Phone” dial *#06#. A system message with a fifteen-digit number will appear. This is your phone's IMEI. Compare it with what is written on the box or under the batteries. If these numbers do not match, then you will have to reflash the phone.

If the above does not help, or if the phone is single-SIM, then you should check the following:
Firstly, the contacts of the SIM card or the slot for it could become dusty or, on the contrary, fog up after being in a dusty room or in a room with high humidity. In this case, it is enough to wipe the contacts with alcohol. Under no circumstances should you use perfume or cologne for these purposes, as they contain oils that can settle on the contacts, creating a film that prevents the passage of electrical signals.
Secondly, old SIM cards may simply be incompatible with new phone models, both Android and iPhone. In this case, you will have to contact the nearest office of your telecom operator to reissue the SIM card.

A SIM card is the most important part in any cell phone, since without it the phone cannot be used for its intended purpose. The user will be deprived of the ability to send and receive messages, as well as call anywhere other than the emergency service. Unfortunately, no one can predict the breakdown or malfunction of a SIM card; sometimes such moments come at the most inopportune time. It also happens that the phone does not detect the card and informs the owner about this, demanding to insert the card into the slot in which it is already located. You can learn what to do in such situations from this article. Several action plans for different situations are detailed below.
How can I find out what is causing the SIM card to malfunction?
The first thing you should do is remove the card from the slot, having first examined its location. It is quite possible that the SIM card has moved a little, as a result of which contact with the phone was lost. In the case when the SIM card slot is located under the battery and not next to it, there is a possibility that the SIM receiver does not contact the card through special micro-contacts. To solve the problem, you should try to press the SIM card more tightly to the slot, using a small roll of paper folded several times. You need to place the package between the card and the battery, and then assemble the phone. It is likely that contact will be restored and the SIM card will function again.
If this does not help, remove the card from the SIM receiver again and carefully inspect all contacts. Are they damaged or dirty? This may be the reason why the card does not work. Take a simple eraser and wipe everything visible contacts, and then insert the card into the slot and start the phone. Works?
Not again? Then bend the SIM card slightly so that the side on which the contacts are located becomes slightly convex. The reason may be that when long-term use The SIM card overheats and begins to deform, as a result of which the contacts of the slot and the card do not touch.
Is your card still not working? Then the problem may lie in the phone itself. To check, insert a card from another operator into your cell phone. If it works, then the problem is in your first SIM card, if it doesn’t work, then the problem is in the SIM receiver.
Why doesn't the SIM card work?
The reason may be in the phone itself; some cell phones are “locked” exclusively for specific operator mobile communications, therefore another SIM card similar phone won't find it. It often happens that in phones with two SIM cards only one of the inserted cards works. Therefore, you should inspect both slots and insert a “suspicious” SIM card into both the first and second.
Many physical damage greatly affect cell phone performance. For example, if water gets on your phone, certain time The contacts of the SIM card or slot may oxidize, which will lead to a malfunction. Regardless of whether your phone has fallen into a puddle or been caught in a light rain, and it seems that water has not penetrated under the case, you should disassemble the device and easily wipe the contacts and places where the cables connect with a napkin. If after cleaning the SIM card still does not work, then the only thing the right decision there will be an appeal to service center, where specialists will solve the problem in a short time.
Take into account the fact that the damage will not show up immediately. After a certain period of time, the phone may suddenly break down, although it would seem that before that it worked perfectly without the slightest suspicion. Even a sharp increase or decrease in temperature can be detrimental to a SIM card or connector. You come in from outside where the weather is cold or humid and find yourself in a warm room, unaware that liquid is condensing inside the phone. Everything is extremely simple: disassemble the phone, remove the SIM card and wipe it with a soft, dry cloth.
What to do when the SIM card is to blame for the problem?
Some SIM cards have a specific expiration date indicated on the starter pack, when purchasing, pay attention to the packaging, it may indicate the service life. If inactive for a long time, the card is automatically blocked or fails, turning into useless garbage. Also, the card may be blocked due to negative balance, preserved for a long time. Each operator sets its own rules that you need to know to avoid problems. Most mobile networks will activate your SIM card only after the first top-up. Often, when purchasing a card, a consultant will inform you on how to properly activate it.
Many modern smartphones have slots that only accept cut-off cards called mini-SIMs. Often iPhone owners and other smartphones are forced to cut the SIM card on their own, which can cause damage. This action You should trust specialists in special centers, or, in extreme cases, people who have previously successfully cut SIM cards and have valuable experience. But still, when the SIM card does not work, you should do the above steps and make sure that you cannot solve the problem yourself.
Contact your mobile operator if you have a problem with your SIM card
The situation when the phone does not see the SIM card can arise for any subscriber Russian operator- MTS, Beeline, MegaFon, Tele2, or Yota. This can happen for a number of reasons, not always dependent on the person using the device. Today we will tell you why the phone may not see the SIM card, and what needs to be done to solve the problem.
Finding out the reason
The main thing to do if the phone does not see the SIM card is to find out the reason. The cause of the problem may be either the device itself, which uses the SIM card, or the card itself.
You need to determine why this is happening - the phone does not see the SIM card at all, or the operator’s network is just unavailable. It's quite easy to find out. If you installed a SIM card in your phone, and the device writes that the SIM card is not installed, this means that the phone does not see the SIM card. If the phone does not display a notification about the absence of a card, but does not see the operator’s network, then this may be due to both the SIM card itself and the device.
There are many reasons why the phone does not see the SIM card, and this problem occurs both on push-button telephone, as well as smartphones on Android and iOS. If cellular telephone does not see the SIM card or the network, then analyze why this problem appeared - after a fall, or a software update, or maybe this situation occurs periodically.
You shouldn’t rush to take a phone that doesn’t see the SIM card for repair, since the problem may lie in the SIM card itself, and you can also solve it yourself. The first thing to do in such a situation is to turn off the device and remove the SIM card. After that, insert the SIM card into the phone and turn it on. If the problem persists, then you need to check the device with a different SIM card, as well as the SIM card in another phone. These simple steps will help you determine why the device does not see the SIM.
If no phone sees the SIM card, then the problem is most likely in the card itself. If the SIM card works normally in another device, then the reason can only be a gadget.
Solution
If the problem is with the SIM card itself, then the only solution is to replace it. There are many reasons why a SIM card can fail: it can be damaged or blocked by the operator.
All mobile operators They replace SIM cards for free, and the procedure itself will not take much time. To do this, just go to the nearest company salon with your passport and apply for new SIM card. Within a few minutes the subscriber will have a new card in his hands.
After replacing the SIM cards, you will have access to: old number, as well as the tariff and services connected to it. The account balance will also be maintained. Paid replacement is made only if the SIM card is sent by mail, which will require some time from the subscriber, since delivery is carried out by regular mail.
Even if the problem lies in the device itself, then you should not rush to the service center, since in most cases the problem can be solved yourself.
Most often, subscribers encounter this problem after updating software, or installing new software. If the problem occurs in this case, then you need to reset the device to factory settings. How to perform this procedure can be found in the user manual, or by contacting hotline manufacturer.
Situations also arise when a person bought a new phone that does not see the SIM card. This mainly concerns gadgets that were not officially imported to Russia and are “locked” either under a specific operator or European providers. If the phone is intended for use in European Union networks, then the situation can be resolved simply by inserting a SIM card from any European operator into the phone. You can remove the blocking for a specific provider (most often this applies to American ones) remotely, using the services of “craftsmen” on the Internet.
If none of these options are suitable - you are not ready to look for a technician on your own online, or buy a European SIM card, then you will have to contact a service center. Please also consider that official services Often such unlocking is not performed, so you need to use the services of unofficial salons.
If the device is not “locked” under foreign operator, or it worked fine before, but now it doesn’t see the card, then you need to contact a service center to have it repaired. We recommend that the device be diagnosed and repaired only by an authorized representative. This will not only allow you to be confident in quality repairs device, but will also help avoid additional costs. This is due to the fact that third party services can be added to the bill Additional services for repairs that were not carried out on the gadget. Also, if the device has a warranty, then its repair will not cost a penny if the cause of the malfunction was not your fault.
conclusions
If the device stops seeing the SIM card, then the first thing you need to do is determine the reason. You can check the functionality of the card itself in any other device, and if necessary, replace it free of charge at the operator’s salon.
If the reason lies in the gadget itself (the SIM works in another phone), then determine why it stopped working normally. If this happened after a software update or flashing, then resetting to factory settings or re-flashing will help.
In case of another problem, you must take the device for diagnostics and repair to the manufacturer’s service center. Don't forget to take with you warranty card, which can save you money.
