The situation where the tray SIM-The card breaks or gets stuck inside the case, is one of the most stressful for the smartphone owner, and it can happen due to a manufacturing defect, moisture, deformation of the case after a fall or the use of poor-quality tools for extraction. Owners of Xiaomi, Redmi and POCO Often faced with the fact that the locking mechanism stops working, and the tray is not extended even with a strong press.
There are several proven ways to solve the problem without going to the service center, but it is important to act with the utmost care so as not to damage the motherboard or the plastic card itself. In this article, we will discuss in detail the algorithms that will help you regain access to the network.
The first thing to do is to assess the scale of the problem: the tray can get stuck due to swollen rubber gaskets or misaligned internal contacts, and brute force attempts are unacceptable here, as they will lead to mechanical damage to expensive components. Below we will look at safe and effective ways to solve this delicate task.
Diagnostics of the problem and preparation of tools
Before you start to act, you need to understand the cause of the jamming. Most often, the locking mechanism is jammed due to dust or oxidation of contacts. Visual examination under bright light will help determine whether you can see the edge of the tray and if there are foreign objects in the slot. If you can only see the inside, you need a thin tool and good lighting.
You'll need a set of simple objects that you'll find in every home, and the basic tool will be a standard paper clip, but in some cases you might need a thinner needle or even a stationery knife, and it's important that the tip of the tool is sharp, but not too thick, so that you don't damage the mechanism of the spring inside the connector.
⚠️ Warning: Never use a toothpick tray to extract! The tree can split inside the hole, and it will be almost impossible to remove the debris without completely disassembling the smartphone.
Also, you can have tweezers with thin tips and a magnifying glass. You'll need tweezers to grab the edges of the tray if it moves a little bit. You'll have the magnifying lens to control the process, allowing you to see the microscopic motions of the machine. Without these tools, the risk of damaging the internal contacts increases dramatically.

The method of paper clips and thin needle: the classical approach
The most common way to get a stuck tray is to use a standard paper clip, you need to unbend it so that you have a straight, thin rod, you need to put the tip of the paper clip right into the opening of the mechanism, feeling the resistance of the spring, and sharp but controlled pressure often helps to move the mechanism from the dead point.
If the paper clip doesn't work, you can try a thinner needle or pin, a thinner needle profile that allows you to penetrate deeper into the locking mechanism, and if you press, try to sway the tool slightly from side to side to release the jammed latch, and the main thing is not to make excessive efforts to break the mechanism inside the case.
In some Xiaomi models, the tray can be blocked due to displacement, in which case try to simultaneously press the mechanism and slightly pull the tray with your nail or tweezers. The combined effect is often more effective than simple pressure. If the tray has moved even by a millimeter, further extraction will be successful.
💡
If the paperclip slides and does not fall into the hole, try to paint its tip with a black marker - so it will be better to see the entry point in poor light.
After successful extraction, carefully inspect the tray, it may have burrs or contaminants that caused the breakage, clean the edges of the tray with fine sandpaper or nail file to prevent the situation from recurring, a clean and smooth tray will enter and exit the slot without difficulty.
Using Superglue: Risky but Effective Method
If the mechanical action is not working, you can use glue. This method requires the utmost care, because the error can lead to irreversible consequences. You need a drop of superglue (cyanacrylate) and a thin wire or match. The task is to glue the tool to the end of the tray without affecting the body of the smartphone.
Put a microscopic drop of glue on the tip of the wire. Carefully touch the center of the protruding tray. Wait for the glue to dry completely, it will take 30 seconds to a minute. Then pull the wire on yourself sharply, but without jerking. If done correctly, the tray will come out with the tool.
⚠️ Warning: It is strictly forbidden to pour glue directly into the slot! Getting glue on internal contacts or motherboard will lead to the need for complex and expensive repairs in the service center.
The alternative to liquid glue is thermal glue, but it's less effective on smooth tray surfaces. Super glue creates a stronger chemical bond with plastic. However, remember, this method is only suitable if part of the tray protrudes outwards. If the tray is completely inside, the use of glue is strictly prohibited.

Disassembly of the smartphone: for advanced users
When external methods fail, the only option is to partially disassemble the device, which is only suitable for those who have experience with electronics and understand the risks. First, you need to turn off the smartphone and remove the back cover. In modern Xiaomi models, the cover is often glued to the surface, so you need to heat the perimeter.
Use a dryer or heating platform to soften the adhesive layer. The temperature should not exceed 80-90 degrees Celsius, so as not to damage the display or battery. After heating, use a suction cup and a thin plastic blade (mediator) to neatly separate the cover. Move slowly, cutting the glue.
Once you remove the lid, you'll have access to the insides of the smartphone. SIM-Often the back of the tray can be accessed through holes in the metal screen or frame. Using a thin tweezer, gently tuck the tray from the inside and remove it.
| Method | Risk of damage | Essential tools | Difficulty |
|---|---|---|---|
| Paperclip/Needle | Low. | Paperclip, tweezers. | Low. |
| Superglue. | Medium. | Glue, wire. | Medium |
| Disassembly of the hull | High-pitched | Hair dryer, shoulder blades, screwdrivers. | Tall. |
| Service centre | Minimum | Professional equipment | Absent. |
Alternative methods and life hacks
There are some lesser-known, but working methods, like using sticky tape, where if the edge of the tray protrudes slightly, you can stick a strip of quality tape or tape and pull it sharply, and the adhesion may be strong enough to extract, but it works rarely and only with minimal stuckness.
Another option is to use a magnet. If your Xiaomi tray has metal elements, a powerful neodymium magnet can help pull it out. Hold the magnet to the slot and pull smoothly. This method is completely safe for electronics, since the static magnetic field does not harm modern components.
Some users advise using a vacuum. By putting a thin tube (like an IV) to the slot hole and creating a mouth or syringe, you can try to pull the tray out. The effectiveness of the method is low, but as a last resort you can try. The main thing is not to create excessive pressure that can damage the microphone or speaker.
💡
The safest and most reliable way is a careful mechanical action with a thin tool, other methods carry additional risks.
Prevention of tray breakdowns SIM-map
To avoid a recurrence of an unpleasant situation, you should follow the rules of operation. Always use the original paper clip or a special key that comes with the package. Third-party tools may have the wrong diameter or shape, which leads to deformation of the locking mechanism. Regularly clean the slot from dust with compressed air.
Don't force the tray. If it doesn't come in, check for orientation and no foreign objects. Dirt and pile stuffed in your pocket often cause a jam. Also avoid moisture entering the slot area, as oxidation of the metal increases friction and leads to corrosion.
If you change often SIM-If your Xiaomi model supports this technology, consider using eSIM, this will completely eliminate mechanical wear of the tray. Otherwise, try not to touch the card unless absolutely necessary to extend the life of the physical slot.
⚠️ Warning: If the tray is deformed (bent or scratched), do not insert it back in.This can lead to jamming of the mechanism at the most inopportune moment.
