Developers of phones, or rather smartphones, never cease to amaze with senseless innovations.
However, you have the right to disagree with my opinion, but, for example, I absolutely did not like, for example, a hybrid slot.
This code can be inserted into it either a SIM card or a micro SD flash drive. Maybe earlier, when there were no two slots at all, such a decision would have been accepted by everyone with a bang.
Only today, no one likes to constantly change cards, but many have to, especially those who call foreign countries.
The second "misunderstanding" is a slot for a key. Not only is it difficult to find, it also requires a key or something like it.
I don’t know why they didn’t like the traditional slot on an ordinary latch - I pressed it once, the slot opened, pressed it a second time, the slot was tightly closed.
If in your smartphone, you can install only one SIM card, that is good way put two -
Simple and convenient, but if this happened, then I will show you how to open a Samsung slot, xiaomi redmi 3, iPhone, Meizu, Asus, Huawei, Lenovo and so on.
How to open the SIM card slot with a key
For those in the know, this might be obvious, but there are a lot of people out there who might miss these micro-holes as they are not well integrated into the design.
Step 1: Locate the small hole on the device body.
Step 2: find the SIM card insertion tool inside your phone box. If lost, you can use something like a paper clip.
Step 3: insert the tool into the hole, press firmly and the slot should pop out.
Step 4: remove the sim card from the tray or carefully place the sim card or USB flash drive into it.
Step 5: insert the tray back into your phone and press on it to close.
NOTE: you can use a paper clip, but beware and never use a sharp object like a pin. This will damage the tray. Also, do not use wooden sticks - they can get stuck in the hole.
How to open a SIM card slot in a samsung / lenovo / xiaomi redmi 3 / meizu 2m / asus / huavei and others
In order to open the "pocket" of the SIM card, you need to find it. It is not difficult - carefully examine the case and you will find a small hole (like a needle).
Of course, I only write about the trays that drive out, because they are still ordinary ones, most often under the battery.
When you find it, insert the key or straightened paperclip into the hole next to the pocket.
A key is a small metal tool that you sometimes get with a new phone, but you can open a SIM card slot without a key.
How to properly open the SIM card tray without a key
If you are a lady or have a girlfriend, almost any earring can open the tray.
Earrings are the simplest and most common tool for this kind of business, and even if they are not at hand right now, they can be quickly found (borrowed).
How to open the SIM card tray with a paper clip
A paper clip is the next most common thing if you happen to be working in an office.
Just beware of a plastic-coated paper clip, any small paper clip will open the tray - just straighten one end and press firmly.
When you're done, don't throw it away, but you can use it in your work to staple different pieces of paper together.
How to properly open a SIM card slot with a needle
If you have repaired socks or trousers, then you will definitely have a needle in the house.
Just use the non-pointed end that you will insert into the hole and press, for example, on the edge of the table.
I would not advise you to try this with your hand. If using sharp objects like needles, then use some hard surface to press.
Of course, there are many other alternatives, including toothpicks, safety pins, or just about any other pointy thing around you.
How to open a SIM card slot on an iPhone
The SIM card slot in iPhone 6 Plus, iPhone 6s, iPhone 5, iPhone 5s iPhone 4, iPhone 4s is located on the side of the device.
As in the picture below, you can open it in exactly the same way as in the phone - the difference is zero.
But in the iPhone 3GS or iPhone 3G in a slightly different place - on the upper edge of the device.
SIM card slot does not open - what to do then
But what if the tray is stubborn and won't open? First of all, try to press harder - often the issue is resolved.
If it does not help, then first you need to put a key or other object into the hole, which is not subject to discussion.
Some people try to glue something to the tray with superglue, but its strength is usually not enough - it comes off.
Just do everything carefully, otherwise you can pierce through some devices with a needle (you will even see a point of light). Therefore, if you use a pin, then it is better to break off the sharp tip (bite off sharper).
It is possible that the SIM card slot does not open due to the fact that it is broken, for example, the contact is bent and caught - if you pull it, you can break it off.
Also, the slot may not open due to the fact that the SIM card falls out of the groove and clings to the connector of the case.
Then you can try using a strip of foil or a razor blade and try to pull it out.
Of course, if the slot does not open due to the fact that the SIM card got up crookedly, then it is better to give it to a specialist right away than to break it and only then send it for repairs.
Even a professional will take time to disassemble some devices - so be careful, otherwise the consequences of inexperienced intervention can result in expensive repairs.
I also suggest watching a video instruction on how and how to open SIM card slots in phones. Good luck.
The following ads are often found on popular Internet sites:
IPhone is on sale. Excellent condition, body and screen ideally, everything works.
There is one drawback: the SIM card slot is broken.
The renovation is inexpensive, but I urgently need money for medical treatment / wedding / funeral, etc. I sell it as it is.
Replacing a SIM card slot is really inexpensive. Depending on the model and service center, this will cost about 2,000 rubles. The iPhone itself is sold for 8-10 thousand cheaper than working counterparts.
For many, such a purchase will seem like a great investment and an opportunity to save money. Give 10 thousand less, and then pay only two for repairs.
How is the on-site inspection carried out in such cases?
When a buyer decides to purchase such a smartphone and meets with the seller, he is given an iPhone in excellent condition. The device is reset to factory settings and the user is greeted with a familiar inscription.
In this form, it will be possible to select a region, language and even connect to Wi-Fi, then the device will ask you to insert a SIM card. This is where the climax begins.
The seller will apologize a thousand times for his mistake, an hour ago the device worked properly, he decided to disconnect it from the Apple ID and make a reset in order to give it to the buyer clean.
The poor man forgot that when activated, you will need to insert a SIM card, and the receiver is broken. He assures that if blocked, he could not reset the device, it would be blocked and would ask for a password from someone else's Apple ID account.
Everything looks logical and believable. The buyer trustingly gives the money and goes to the pre-selected service. Pays a couple thousand more to replace the SIM card tray.
After repair, it tries to activate the device again. The stage with card verification is successful, and then the same warning appears on the screen with the need to enter the Apple ID and password.
The iPhone was stolen or lost, after which the owner locked it via iCloud.
Where is the catch hiding
In fact, the iPhone being sold was initially locked. Such models are usually sold very cheaply for organs. But enterprising scammers try to sell locked devices under the guise of broken ones.
They deliberately damage the SIM card receiver. To do this, it is enough to dig deeper into it with a paper clip or a toothpick. Then the smartphone is dropped and put up for sale.
How not to fall for this scam
Apple ID health check and disconnection is the first thing to look out for when it comes to iPhones.
Nothing can be done with a locked device. We'll have to carry this brick to the nearest radio market.
Do not buy equipment that you cannot test
The most inquisitive ones can find the IMEI code of the device on the welcome screen, compare it with the code on the box and back cover (SIM card tray). Next, check the status of the device by code, for example,.
But even then, it's too early to relax. It is best to invite the seller to go to the service center, pay for the repair, and only then give the full amount for the device. To do this, it is better to find in advance a free master who is ready to immediately start working.
This is how we arm you with new knowledge and warn you about possible dangers when buying a gadget from your hands.
To this topic:
Components in a computer often break down, and this is not unusual. Despite the simplicity of slots random access memory, they also deteriorate.
No one ever repairs RAM, they just replace it. However, this is only possible if it is under warranty. The manufacturer himself, most likely, tritely disposes of the defective or damaged slot, and gives the buyer a new one. If the memory is out of warranty and you are sure that it does not work, then just throw it away. Repair ... well, it is possible in theory by soldering some microcircuits that could have been damaged, but using such memory is not worth it. No one will guarantee its efficient operation.
How to check if a memory slot is working?
If your system simply does not recognize the memory in the system, this does not mean that the slot is not working. For example, 32-bit operating systems do not see more than 4GB of memory. You can insert at least 16 GB into your computer, but the system simply will not see it. But 64-bit systems see everything! Therefore, if you have 2 slots of 4 GB and a 32-bit operating system, try to insert slots separately and look in the characteristics of the computer to see if the volume is displayed in the system. If each of the slots is displayed separately, then they are clearly working.
Further, there is a discrepancy between the architecture of the processor and the motherboard and the amount of memory used. The fact is that the same 16 GB of RAM, for example, cannot support motherboards. The characteristics usually indicate what the maximum volume the board can "see" in the system. motherboards most laptops are rated for 8GB of RAM. If you insert 2 slots of 8 GB into it, then 16 GB will still not be displayed, but this does not mean that the slot is faulty.
Well ... and if the RAM slot really doesn't work, then at least you can try to wipe the contacts with a rubber float (like in school). Sometimes (in about 10% of cases) it helps and the system starts to "recognize" the RAM again. Of course, the chances that this will help are small, but it is worth trying.
In other cases, take the slot to the manufacturer / seller, if there is a guarantee, either for repair, or throw it in the trash can.

On the weekend, a friend brought explay tablet surfer 8.31 3g. When the tablet fell off the table, the back cover of the tablet opened, pulling the SIM card inserted into the slot. Alas, such situations with your favorite gadgets have certainly happened to many of you. However, with a strong desire, this problem can be solved on your own.
As you can see in the photo, the slot was torn out, and on one side, along with the foil glued to the board (blue circle). It's good that this section of the foil is not a track and you can safely put it in place (glue it).
The broken-off slot legs and their remains on the tablet board are marked with a red circle.
Upon examination, it was discovered that the SIM card was not fixed, that is, the slot itself was damaged. Of course, I would replace it with another one, but the nearest specialized store where you can buy a slot is 150 km away. Having learned about this, a friend asked me to remove the fixation and put the slot as it is (remove the spring so that the SIM card does not come out). But I could not just pull out these parts, because if I later needed to change the SIM card or, for example, I had to open the case, it was impossible to do without breaking the slot again.
The photograph (after repair) shows that on this tablet model, the SIM-card is inserted deeply and it is almost impossible to pull it out without the ejection mechanism.
Thus, I had to repair the slot itself first.
When I removed the metal cover, I saw that the wire that looked like a staple clip (only much smaller) was missing. She fixed a plastic piece that pushes out the SIM card under the action of a spring.
The red circle marks the place where the locking bracket should have been.
The wire for the staple needs to be stiff in order to accelerate back, so I made the staple out of spring steel of a suitable diameter.
The diameter was determined by the hole where the native bracket was installed.
Slightly straightening the spring, bent the tip with pliers and bit off. After nibbling, the end of the wire resembled an ax blade. So that he does not damage the plastic parts of the mechanism, he rounded off its end with a diamond file.
Temporarily removing the push-out spring for convenience, put the SIM-card in place and, thus, found out the length of the retainer.
I made the length of the legs of the bracket so that it did not exceed the thickness of the base of the slot. Otherwise, the end of the bracket, which is inserted into the base itself, could damage the tablet board.
This is the most a big problem when the tablet was repaired (slot restoration), another one was completed - installing the slot in place.
Slot installation
If there was a new slot, installation would not have been a problem, but since the legs of the native slot also suffered, I had to tinker with them.
To begin with, I removed the remnants of the legs from the board, polished the soldering places with a soldering flux and began to solder. Soldered with an ordinary 40 W soldering iron, although it is better to solder such parts with a soldering station. I started by gluing and soldering the body of the slot, then the legs themselves. The short ends of the slot legs did not reach the place where they were soldered, and the legs had to be extended with a thin copper wire. I had to solder each leg, trying not to touch the already soldered one, and they are at a very close distance (this is not an exercise for the faint of heart). Finally, he wiped off all the places where there were flux residues with alcohol.
If anyone decides to try to fix the slot breakage himself SIM cards, I want to warn you: on explay surfer 8.31 3g, the battery is glued to the back cover, be careful when disassembling. With a sharp opening of the lid, serious breakdowns are almost guaranteed. At least pull out the battery plug from the board, damage the cables and, of course, the wires that go to the speakers (marked in red).
When soldering, do not overheat the board and slot.
Be careful not to create bridges (blots) between the tracks.
When repairing, it is advisable to have a magnifying glass at hand, preferably a microscope.
A soldering iron needs a small power, or better a soldering station, otherwise the slot may melt and the tablet board may overheat.
Do not use a sharp object (needle) to remove the remaining rosin, as you may damage the tracks on the board.
Memo: if there is no experience in repairing radio electronics, you should not even try, otherwise the consequences of such repair (already in service center) will cost much more, or may not accept the device at all.
