22.07.2021 Gralbine Samsung

What to do if the Samsung phone does not see the SIM card

There are several reasons why the phone does not see the contacts on the SIM card or the card itself. They can be divided into two groups:

Oxidation and failure of phone contacts;
Breakage of the microcircuit on the SIM card;
Damage to the rest of the internal parts. board or microcircuit

Software glitch i.e. malfunctioning software.

What to do if the Samsung phone does not see the SIM card. methods of solving the problem

A SIM card is a cellular subscriber identification module. Without its correct operation, such operations as making and receiving calls, sending SMS messages, as well as the real functioning of certain applications, are impossible. Sometimes the phone can malfunction, refusing to create the installed card of the 1st of the mobile operators. In the article, we will see what to do if the Samsung phone does not see the SIM card.

The main premises of the problem

All the main prerequisites for problems with a SIM card can be roughly divided into two categories:

Physical malfunctions. These include damage to phone components, oxidation and contamination of contacts, burnout of the SIM card chip.
Software crashes. This group of faults includes difficulties with the smartphone software.

Let’s take a closer look at possible methods for eliminating problems in each of the categories presented.

Elimination of software breakdowns

Software problems appear in the operating system of the phone and can only be solved using radical methods: resetting to industrial options or flashing the smartphone.

A hard reset can be performed in several ways: via the phone options menu or launching Recovery Mode.

After the procedure, all user data will be deleted, therefore, you should transfer the fundamental files to a computer in advance or put them in a cloudy storage.

Re-flashing the operating system will require certain knowledge and the introduction of special programs. If Samsung does not see the SIM card after installing the updates, then you need to search for the previous firmware version, which will be missing the specified discrepancy. In the future, you should disable automatic updates (at least, until another version of the software is released).

If there is no self-confidence or annotations for self-installation of OS are superficial, it is better to seek help from a specialist.

Why does the phone not see a SIM card and what to do with it

The phone may not create a SIM card for several reasons:

Simka is damaged. Maybe you damaged your contacts when you tried to insert it into your phone. Simka could not be able to work due to old age. Contacts over time can become rubbed, oxidized, etc.
The tray is not inserted correctly. In modern devices, the SIM card is located on a special tray. It may be that you didn’t push it all the way.
An error occurred while trying to flash or update the operating system on the phone, which resulted in a malfunction. As a result, the phone no longer sees the SIM card.
Airplane mode was accidentally activated.

We told you about the prerequisites, now let’s talk about how to solve the problem:

After checking the flight mode, it is worth trying the most common method. restarting the phone. You will be surprised when you find out how often he specifically solves a problem.
Another method is to pull out the sim card and insert it back.
If the first two methods did not lead to the desired result, and there are no signs of damage on the SIM card itself, try to remove it and insert it into another phone. If it works in it, it means a discrepancy is uniquely associated with your device. Inspect the tray for damage. If you have recently updated the software, you should roll back or completely reset the device to industrial options. True, before the last step, we advise you to check whether another SIM card works on the device.
If you find traces of damage on the SIM card itself, you should carefully clean the contacts. It is recommended to do this with a regular eraser. Another option is a microfiber cloth lightly dampened with alcohol.
If it was not possible to bring the SIM card back to life without the help of others, contact the operator’s office. For you without any problems, they will change it to the newest one. If the discrepancy is related to the device and it did not work out in home criteria, go to the service center.

As you can see, you can quickly realize why the phone finished creating a SIM card and, in some cases, deal with the problem given to us in a few minutes.

For what reasons the SIM card is not seen and how to fix it

Sometimes it happens that the phone stops generating the SIM card. The problem is nasty and deprives the user’s phone of the main function. to make calls. In the article, we talk about the main causes of the onset of the disease and how to deal with it.

Elimination of hardware failures

In this section, only those methods of solving the difficulty will be presented that can be performed without the help of others at home.

If the advice does not give a suitable effect, you should contact the service center or a specialist for diagnostics and the next repair.

The main steps to eliminate physical damage look as follows:

Checking the correctness of the installation of SIM-cards. Maybe the element was simply installed by the wrong side, which became a prerequisite for the lack of contact.

There are a number of root causes associated with the malfunctioning of a SIM card. Let’s take a closer look at each of them:

Mechanical damage to the element. You should check the SIM-card for severe scratches, chips and bends of the microcircuit. If there are any, you will need to contact the customer service center for replacement.

Among the problems related to the SIM card, there may also be those that do not belong to mechanical damage:

Shutdown due to long inactivity. Mobile operators disconnect subscriber numbers if during the year the account has not been replenished by any amount. By calling from another phone, you can find out the current status of the number and the possibility of its restoration.
The new card has not been activated yet. Balance replenishment often solves the issue.

The third reason why a Samsung smartphone or tablet does not see the SIM card. contacts

The next step is to clear the contacts on the SIM itself. To this end, we achieve 40% alcohol concentration (regular vodka).

There can also be a degreasing liquid. this is the best tool for and cleaning electronic surfaces.

Just apply 10 ml on an anti-static cloth (avoid paper due to its ability to carry electrical charges) and polish the inside of the SIM card, which is with contacts.

[info] If Samsung stopped seeing the SIM card after the fall, then most likely it will not be possible to do without the service, as the module could be damaged. [/ info]

The second reason why Samsung stopped seeing the SIM card. slot

Despite the use of various sealants in the SIM card slots, it is highly susceptible to various types of contamination.

A small crumb is enough to block the connection between the SIM card and the smartphone. In this case, it is worth turning to compressed air, since the presence of moisture can negatively affect.

Therefore, it is not recommended to come into contact with this element with moisture, as this may damage the Samsung phone itself.

Here, a lot also depends on the slot itself, there are open “everything in sight”, and there are those that cannot be reached without disassembly.

The fourth reason why the Samsung phone stopped seeing the SIM card. coverage

The very rapid growth of 4G infrastructure and the need for work includes the shutdown of some transmitters.

It is possible that your phone has been in an operator-disabled area for some time. In this case, most smartphones will automatically connect to another GSM network.

There are a few percent chances that your Samsung was out of reach. For this purpose, also try to enable roaming, which allows you to use another GSM network.

If Samsung stopped seeing the SIM card after the reset, then it may simply not be enabled in the settings.

The first reason why Samsung does not see the SIM card is a failure

The information contained in this miniature integrated circuit allows you to communicate freely, write text messages and go online.

What to do in case of an unexpected failure? It’s OK. Modern technology often does not work like that

Before sending your smartphone for repair, make a trivial act, which is an effective way to solve 90 percent of mobile phone problems.

It is reboot or shutdown and power on your Samsung duos, Samsung note, Samsung Galaxy s4, s3, j3, s5250, gt s5250, s7, j5, s6, s8, a5, s5, j1, t285, a3, i9300, s5, i9505, gt s5230, s6 edge, n8000, gt n5100, s3 i9300, p5100, j1, 5620.

A regular restart can be a recipe for all hardware failures, not just if you can’t see the SIM card.

reasons why the Samsung tablet or smartphone does not see the SIM card

You saw an alarming message turn on the phone, and an unwanted message appears on the screen in the form of the words: “SIM card error”?

Most owners tend to panic, but you do not seem to be one of them, as you are looking for solutions to what to do.

Despite all the tremendous possibilities available to modern smartphones, each of them will become almost useless if they lose touch with the world.

This can happen for a number of reasons with any Samsung Galaxy phone duos j3, a3, a5, s4, a7, c4, j5, a6, j2, s6, j1, s4, s3, s7, a8, s8, j7, c3, c7, gt 19003, gt s5250, gt e1200m, g318h and in most cases it does not depend on the operator, like tele2, mts, beeline or megaphone.

This does not have to be a malfunction of the smartphone itself. Sometimes the reason is the SIM card.

Then many people decide to put their favorite cell phone in the hands of an operator. Only if you care about time and want to save it, use the suggested methods first.

The fifth reason why Samsung does not see the second SIM card. conclusion

If your phone does not see the 2nd (second) SIM card, then keep in mind that not all Samsung devices can simultaneously work with two SIM cards at the same time.

If you are sure that 2 are working at the same time, then try this trick. Paste and disable in settings. Then pull it out. Reboot the device, insert and then turn on in the settings.

Such a simple method sometimes solves the problem. If the problem is still not resolved, it remains to choose a more radical operation in the form of a system reset to factory settings.

Before doing this, you must back up all data that is important to us. The device will be completely cleaned starting from login data through system preferences, music apps, documents and more.

Just before doing this, it is worth checking whether another card will work in another phone. If none of the above methods helped, then you have no choice but to contact the operator.

There, quickly solve your problem. An employee can exchange your SIM card. In any case, sooner or later you will be able to use your smartphone again. Success.

Elimination of hardware failures

This section will present only those solutions to the problem that you can do yourself at home.

If the recommendations do not give the desired effect, you should contact the service center or a specialist for diagnostics and subsequent repair.

The main steps to eliminate physical damage are as follows:

Checking the correct installation of SIM-cards. Perhaps the element was simply installed on the wrong side, which caused the lack of contact.

Testing the SIM card and mobile device. You should install the card in another phone, if everything works fine there, it means that the problem is in the device, if not, the reason for the problem is in the SIM card. The result depends on what you have to do when Samsung does not see the SIM card.

Elimination of problems with the phone is to check the contacts going to the SIM card. The procedure is doable if you have a removable battery. It is necessary to wipe the contacts with alcohol and bend the metal part slightly for a better fit. Also, the culprit of the problem may be a software failure, which will be discussed below. In all other cases, the smartphone will have to be sent for inspection to the master.

A number of root causes are associated with the incorrect operation of the SIM card. Let’s take a closer look at each of them:

Mechanical damage to the element. You should check the SIM-card for strong scratches, chips and bends of the microcircuit. If there are any, you will need to contact the customer service center for a replacement.

Deformation of the SIM card. Long periods of operation and exposure to high temperatures can cause slight bending of the plastic, which affects the tightness of the contacts. It is necessary to bend the SIM card a little so that the side with the microcircuit is slightly convex. The main thing here is not to overdo it, otherwise you can break the element.

Microcircuit contamination. What if Samsung can’t see the SIM for this reason? Wipe the metal part with alcohol to remove dirt and other obstructions.

Among the problems related to the SIM card, there may also be those that do not belong to mechanical damage:

Shutdown due to prolonged inactivity. Mobile operators disconnect subscriber numbers if the account has not been replenished by any amount during the year. By calling from another phone, you can find out the current status of the number and the possibility of its restoration.
The new card has not yet been activated. Balance replenishment often solves the issue.

Mechanical damage to a mobile device and how to eliminate them

When problems arise with the operation of the SIM-card, the first thing to do is to remember whether the phone has been exposed to any external influences. So, if you drop it, there is a possibility of failure or unsoldering of the power amplifier, microcontroller, connector or other module. In such cases, it is better to contact the service center.

To fix the problem, you need to repair IMEI. This can be done through the engineering menu:

Turn off the device and remove the SIM card from it.
Turn it on, and then use the numeric keypad to enter the combination # or ###. After that you will be taken to the engineering menu.
Open the CDC Information. Radio Information section.
Go to the Phone 1 tab and in the top line after “AT” type EGMR = 1.7, ”IMEI”. The quotes indicate the identifier of your mobile phone. It can be found under the back cover of the Samsung Galaxy.
In the Phone 2 tab, enter the IMEI for the second SIM. Only in this case, after “AT” it is necessary to indicate “EGMR = 1.10,”.

After restarting the phone, IMEI will be restored and everything should work. If this does not help get rid of the problem, you will only have to reset all settings to factory settings or reflash your smartphone via PC and Samsung Kies.

First of all, a telephone is a means of communication, and only then is a multimedia player, a tool for surfing the Internet, a camera, etc. And if the smartphone does not accept a SIM card, its main function will be unavailable.

Why Samsung phone can’t see SIM card

First of all, a telephone is a means of communication, and only then a multimedia player, a tool for surfing the Internet, a camera, etc. And if the smartphone does not accept a SIM card, its main function will be unavailable. SIM card problems on Samsung Galaxy can arise for various reasons. Some of them can be eliminated on their own, while others require more professional intervention. Let’s take a look at why Samsung can’t see a SIM card and what to do in a specific case.

The main causes of the problem

All the main reasons for problems with a SIM card can be roughly divided into two categories:

Physical malfunctions. These include damage to phone components, oxidation and contamination of contacts, burnout of the SIM card chip.
Software crashes. This group of faults includes problems with the smartphone software.

Let’s look in more detail with possible troubleshooting methods for each of the categories presented.

Card does not fit well on the receiver

A similar situation can happen when the SIM card was not inserted neatly or correctly into the tray. Sim card pins may bend or break off. If the card tray is retractable, careless use may also damage or deform the card tray.

Also, a similar problem can arise when water gets inside, because it destroys the elements of the circuitry of the card capture reader and oxidizes the contacts. There is only one way to solve this. contact the specialists at the service center.

Samsung does not see the SIM card: causes of the problem and solutions

It is not uncommon for the phone to suddenly stop recognizing the card. Don’t panic. in the case of Xiaomi, the problem is solved quickly. Let’s figure out why the Xiaomi phone does not see the SIM card and what to do.

Other cases

There are situations in which the reasons for not recognizing the SIM are on the surface. For example, this is roaming. to open visibility, turn off automatic network selection, manually set the desired one. Keep in mind that after this there will be a redirection to intranet roaming, which is expensive.

If you cut a SIM card to reduce the size, and it stopped working immediately or over time, buy a new one. Falls, drowning of the phone, which were recently, a probable cause of incorrect operation. Take the measures right away or contact the service.

When it is the SIM card that does not work, its replacement will help. If the card is yours, there are no problems. come to the salon of the mobile operator with your passport. In cases where the SIM card is registered to a third party with whom there is no connection, a small scandal will help. Say that the operator was called, and he promised, demand a replacement from the manager. It helps 90% of the time.

Possible causes of the problem

mechanical breakdown of the device into which the SIM card is inserted;
glitch in software.

First steps

If you suddenly find that the Samsung phone does not read the SIM card, do not rush to carry the phone to the service. To get started, take the following steps:

Remove the SIM card from the device, turn it off, insert the SIM card again and turn on the device. In most situations, such actions help to cope with the problem (if the reason was a software failure).
Make sure the Samsung SIM card is tight in the slot. If this is required, press lightly on the holder at the edges for better fixation and better grip on the contact connections.
If there are two slots, install the SIM in another slot and check if the phone sees a SIM card or not.
Ensure the integrity of the SIM by installing it in another phone or tablet.
Put a different SIM card in your Samsung Galaxy to check the functionality of the connector.

The above steps allow you to first verify the reasons for the current situation.

Problems of “Chinese” devices

If you know that your device is not original and it does not see the SIM card, then you can turn it on yourself.

To do this, go to the tablet settings,
then find the menu labeled “Network”, “Antenna”, “Connection”,
“Operators” and so on. In this section, there must be a manual network search.
Click on it, all available networks should appear, then select your operator from them and connect, the SIM card should work.

If the problem is with the SIM card

If you have established by any of the methods that the reason for the occurrence of this error is in the SIM card itself, then here too there may be various options for its failure, and now we will consider them in more detail.

The card has expired. If you have not used the card for a long time (usually 180 days), then it is automatically blocked or disabled. You need to contact your operator and clarify the conditions for blocking. The operator will answer for sure whether or not your card was blocked.
The SIM card needs to be activated. Some telecom operators distribute their cards free of charge, but it will not be possible to use it until it is activated. How to activate the card of a specific operator, check with the operators. Or you can see instructions for each operator in the corresponding sections of our website.
Damage to the card in the process of mechanical impact. Quite often, cards are damaged in the process of an unsuccessful attempt to cut it and make it from a regular SIM mini or nano-SIM. In this case, you will have to receive a duplicate, since it can no longer be restored because you damaged the microcircuit chip when you tried to cut it.
Damage to the card. In the course of long-term use, the card may simply be damaged due to frequent mechanical stress on it. For example, you quite often take it out of the tray or carelessly carry it in your. as a result of which the microcircuit chip was damaged.

Remove SIM card and battery.

Another basic solution you can try is to remove the battery (if removable) and SIM from the SIM tray. Make sure you turn off your Android device before doing this. After you have deleted everything, wait for about one minute and re-insert everything again.

It is common practice to drop the phone, but even if it was not hurt, the SIM card could budge. A cheap and unique method that many have tried is to add some paper or even tape for a snug fit. This usually allows you to insert the SIM card tightly and tightly and solve the problem.

Mechanical damage to a mobile device and how to eliminate them

If there were no prerequisites for a Samsung breakdown, try the following:

Reboot your smartphone. The problem may lie in a single software glitch.
Take out the SIM card and put it in another phone. This will eliminate the malfunction of the SIM card itself.
Make sure the card is installed correctly.
Wipe the SIM and the connector on your mobile phone with a soft cloth moistened with alcohol. The cause of the malfunction may be trivial contamination or oxidation of contacts.
Press the SIM card to the card holder and place a piece of paper. There is a possibility that the SIM-card holder is simply loosened.

Troubleshooting when Samsung does not see the SIM card

First of all, a telephone is a means of communication, and only then is a multimedia player, a tool for surfing the Internet, a camera, etc. And if the smartphone does not accept a SIM card, its main function will be unavailable. SIM card problems on Samsung Galaxy can arise for various reasons. Some of them can be eliminated on their own, while others require more professional intervention. Let’s take a look at why Samsung can’t see a SIM card and what to do in a specific case.

Software malfunctions

If you are the owner of a dual-SIM Samsung and the SIM card is not visible only on one of the connectors, see if the second slot is enabled in the device settings. The required function is in the section “SIM-cards management”.

Troubleshoot SIM problems

If you have determined that the SIM card itself is the source of all troubles, it is recommended to proceed in the following order:

Call the Support of your operator and see if the card has been blocked. This can happen if the SIM-card is not used for a long time.
If you have installed a new SIM card in your phone, it may not be activated. To activate, you will need to deposit money to its balance.
Visually inspect the SIM card for scuffs, scratches and other defects. If you find them, change the card at the nearest service center of your operator.
If the SIM was lying near the magnet for a long time, it could be demagnetized. In this case, you will also need to contact the mobile office.

To fix the problem, you need to repair IMEI. This can be done through the engineering menu:

Turn off the device and remove the SIM card from it.
Turn it on, and then use the numeric keypad to enter the combination # or ###. After that you will be taken to the engineering menu.
Open the CDC Information. Radio Information section.
Go to the Phone 1 tab and in the top line after “AT” type EGMR = 1.7, ”IMEI”. The quotes indicate the identifier of your mobile phone. It can be found under the back cover of the Samsung Galaxy.
Confirm your changes by pressing SEND AT COMMAND.
In the Phone 2 tab, enter the IMEI for the second SIM. Only in this case, after “AT” it is necessary to indicate “EGMR = 1.10,”.
