Owners of smartphones Xiaomi, Redmi and POCO Often, they need to be replaced quickly. SIM-It may seem difficult, but it's not always a regular tool that's on hand, and when you need to get a SIM card right away and you don't have a paper clip, it's a tricky thing to do, but it's a question of understanding the design of the tray. The extraction mechanism is designed so that the pressure on the hidden button throws the tray out, but this requires a thin and durable object.
In this article, we will discuss in detail how to safely remove the tray using improvised tools, and why a regular sewing needle can be a risky choice.We will look at the anatomy of the slot, the possible risks of damage to the device and the algorithm for dealing with emergency cases when the tray is jammed. Understanding these nuances will help you avoid expensive repairs in the service center.
Many users underestimate the importance of the right tool, relying on the occasion. However, the ejection mechanism in modern smartphones is fragile enough that careless handling can lead to breakage of internal pins. Our goal is to provide comprehensive information that will preserve the integrity of your gadget and ensure a stable connection.
Slot anatomy SIM-maps in Xiaomi smartphones
Before we start extracting, we need to understand what we're interacting with. Xiaomi devices use a standard combined or separate slot, which is a miniature mechanical assembly. Inside the case, there's a spring mechanism that pushes the tray when you press a special lever through a hole on the end of the case.
The pinhole has a well-defined diameter, designed for a standard staple. Using too thin items, such as the finest sewing needles, is dangerous because they can slip past the lever and rest against the side wall or, worse, damage the internal electronic board. Xiaomi Mi, Redmi Note and POCO use a similar design, but the depth of immersion can vary.
It's important to note that in some models, especially those with moisture protection, a rubber sealing ring is installed around the hole. A rough intrusion can displace or tear this seal, resulting in a loss of protection from dust and moisture. So the accuracy of getting into the hole is critical to the success of the operation.
⚠️ Warning: Never use angled sewing needles without first tipping the tip.A sharp angle can scratch the inner walls of the channel or damage the micro-contacts of the board if the tool slips.
Why can the tray get stuck?
Tool preparation: how to replace the staff clip
The ideal tool is a regular metal clip that comes with the kit. If it's lost, you have to find one that meets the criteria for strength and thickness. A regular paper clip that is unbended by pliers is often the best solution, because its diameter is ideal for calibrating the hole.
If you don't have a paper clip on hand, you can use a thin pin, but with great care. A sewing needle is only permissible as a last resort, and it is better to seed it a little or blunt it against the stone to remove the cutting edge. The tool should not be more than 1.2-1.4 mm thick, otherwise you risk breaking and breaking the plastic case around the hole.
It is not recommended to use toothpicks, as wood or plastic can break inside the hole, creating an even more serious problem than a stuck one. SIM-Also avoid using knives or blades that can damage the outer frame of the smartphone.
- 📌 Stationery paperclip: the best option, optimal thickness and rigidity.
- 📌 Pin: fits, but requires caution due to sharp tip.
- 📌 Carnation earrings: often have suitable leg thickness but can be short.
- 📌 Special key: a universal tool for extraction SIM, sold in electronics stores.
💡
If you use a sewing needle, wrap the blunt end in a small piece of tape or tape, which will increase the diameter to the right size and protect the finger from the pressure of the sharp edge.
Step-by-step instructions: how to get a tray with a needle
The extraction process requires calmness and a firm hand.Switch off your smartphone first if possible to avoid software errors when identifying a new one. SIM-Find a hole on the end of the device: in most Xiaomi models, it is located on the lower end next to the connector. USB, In some models, it may be on the top of the.
Insert the prepared tool (needle or paper clip) perpendicular to the surface of the body strictly in the center of the hole. You do not need to push hard; the mechanism is triggered by a point pulse. Press confidently, but without jerking until you feel a slight click and you see that the tray is slightly outwards.
Once the tray has jumped, remove the tool and with your fingers, gently pull it out to the end. SIM-If you have a card, or you don't drop the card if it pops out, smooth movement ensures that both the tray and the inner spring are safe.

What to do if the tray is stuck and not removed
When the tray fails, it is not common, but it causes panic. If standard pressing does not help, do not use excessive force. First, check if you have confused the hole: in some models, there is a hole next to the hole for the SIM, which also responds to pressing, but does not push anything out.
If the hole is correct, it may have been stuck due to dust or deformation. Try wiggling the tool slightly inside the hole (literally by a millimeter) to find the right angle of impact on the lever. Sometimes, light pressing on the tray with your finger while pressing the needle simultaneously helps - this can relieve stress from the stuck spring.
In case the tray popped out partially but stuck, do not pull it aggressively with your nails or tweezers, which can cause the plastic tray to be removed from the metal base. Use a thin tweezer with flat sponges to grab the edges of the tray and, swaying from side to side, slowly pull it out.
⚠️ Warning: If the tray is not removed after a few careful attempts, stop the action. Further diligence may lead to a breakdown of the internal mechanism, and then you will need to disassemble the smartphone in the service center.
Comparison of extraction methods: risks and effectiveness
Different tools carry different risks, and so you can choose the safest option in your situation, we've prepared a comparison table that shows why a paper clip beats a sewing needle in most safety settings.
| Tool. | Risk of damage to the shell | Risk of failure of the mechanism | Efficiency |
|---|---|---|---|
| Staff clip | Minimum | Minimum | 100% |
| Office paperclip | Low. | Low. | 95% |
| Sewing needle | Medium (scratches) | Medium (thin rod) | 80% |
| Toothpick | Tall (breaks inside) | High (stuck) | 30% |
As you can see from the table, using inappropriate items greatly increases the risks. A sewing needle has a diameter of about 0.6-0.8 mm, whereas a standard hole caliber is about 1.2 mm, which creates a backlash and a risk of slipping, which is why, if you have to use a needle, act with utmost care.
Also consider the material of the case of your smartphone: in aluminum or steel frames, the risk of damage to the hole is lower than in plastic cases of budget Redmi models, where plastic can easily deform at the wrong pressure angle.
Tray care and prevention of problems
To avoid the question of how to get a SIM in the future and not damage the phone, it is recommended to carry out prevention. Periodically, every six months, remove the tray and wipe it with a soft dry cloth, which will remove oxides and dust that can accumulate on the contacts and in the grooves.
Pay attention to the situation SIM-If the card is inserted curved or has a non-standard shape (for example, cut manually from a larger format), this can lead to jamming of the mechanism when the mechanism is re-closed.
Use protective cases that have the right cutout under the SIM tray. Some cheap cases have too narrow holes, which when removed, the paperclip can slide along the edge of the case and scratch the phone body, instead of hitting exactly the target.
💡
Regular cleaning of the tray and the use of high-quality, evenly trimmed SIM-cards prolong the life of the extraction mechanism and prevent jamming.
