A situation where urgent changes are needed SIM-A card or a memory card, and you don't have a key, which is familiar to many smartphone owners, is a classic problem that comes at the most inopportune time, like when you're on a trip or you've lost the original hardware. Xiaomi, like most modern manufacturers, uses compact trays that require a point mechanical impact to extract.
Fortunately, the design of smartphones allows you to solve this problem with the help of improvised tools, if you act carefully and understand the mechanism. In this article, we will discuss in detail how to open a SIM on Xiaomi without risking damage to the body or insides of the gadget. We will look at the proven tools that are found in every house, and discuss methods that are better to refrain from.
The main rule before any manipulation is to stay calm and not use excessive force. The mechanism of the ejector is designed for a certain pressure, and exceeding it can lead to failure. Below we will provide a step-by-step algorithm of actions and a list of items that will be an effective replacement for the standard paper clip.
Alternative tools for extracting the tray
The first thing that comes to mind when looking for a replacement is a regular paper clip, which is really the most popular and often the only true option in everyday life, but it is important to use a clip of the right diameter: too thin wire can bend inside the hole, and too thick will not enter the socket.
If there's no paper clip, a regular sewing needle is a great option, and it has the necessary stiffness and a thin point that easily enters the opening of the mechanism. It's important to remember that the needle can be sharp at both ends, so you need to hold it carefully so you don't get hurt. It's also a common use of carnation earrings if they have a thin and strong pin.
- 📎 Stationery paperclip is a classic option that is available in any office or house.
- 🪡 Sewing needle – requires caution, but is perfect in diameter.
- 💎 A carnation earring is convenient if the decoration has a thin and hard rod.
- 📏 Thin part of mechanical handle – suitable only for some models with a large hole.
⚠️ Warning: Never use knives, a sewer or other sharp metal objects with a wide blade.You can slip and damage the screen or scratch the frame of your smartphone, and injure your fingers.
Some users try to use toothpicks, especially wooden or plastic ones. This is a valid method, but it has its limitations. The tree can split inside the hole, and you have to remove two items instead of one. Plastic toothpicks are more reliable, but their strength depends on the quality of the material. If you hear a crunch or feel that the object is deforming, immediately stop the pressure.
Preparation of the smartphone for the procedure
Before you start physically affecting the body, you need to properly prepare the device, which minimizes the risk of accidental data damage or software failures. Although tray extraction is a mechanical action, modern smartphones can respond to a change in configuration. SIM-map.
It's recommended that you turn off the device completely before you start surgery, and it's not just about keeping your contacts safe. SIM-cards from potential power surges (although the risk is minimal), but will also prevent accidental touchscreen taps while you focus on the end of the phone.A switched-off phone is also easier to hold in your hands, as vibration from notifications won't interfere with the process.
☑️ Preparation for tray removal
Look at the end of the smartphone in good light. Find a small circular hole next to the tray. In modern Xiaomi Redmi and Poco models, it is often combined with a noise reduction microphone, but differs in location. The SIM hole is always directly on or close to the tray frame. Make sure that there is no dust or pile in the hole that can interfere with the input of the tool.
Step-by-step: how to open the tray
The tray extraction process is universal for most models, whether it is a budget Redmi Note or the flagship Xiaomi Mi. Take the chosen tool (clip, needle) and position it perpendicular to the plane of the end of the smartphone. This is a critical point: the angle of entry should be 90 degrees. If you press at an angle, you risk bend the tool or damage the inside of the mechanism.
Find a small indentation on the frame of the tray. Carefully insert the tip of the tool into the hole to the point. You should feel a solid resistance, this is the spring of the mechanism. At this point, you need to make a confident, but not sharp, movement, pressing directly into the body, you do not need to twist the tool or try to tuck the tray from the side.
Algorithm of action:
1. Place the phone on a hard surface.
2. Direct the instrument strictly perpendicular (90°).
3. Push until you click.
4. Remove the tray with your fingers.Once you hear a slight click, or feel the tray moved 1-2 millimeters, stop the pressure. Then the mechanism will work automatically with the spring. Snatch the edge of the tray with your nail or tweezers and smoothly pull it out. If the tray does not come out after pressing, you may not hit the right point or the tool is too thick.
💡
If the tray is tight, try swaying the tool slightly from side to side (literally by a millimeter) to find the center of the hole, but don't take it out completely in the search process.
Tool and Risk Compatibility Table
Not all items are equally safe to use, and here is a table that will help you assess the risks of choosing a tool at hand, and we've analyzed the most popular options that users try to use in emergency situations.
| Tool. | Efficiency | Risk of damage | Recommendation |
|---|---|---|---|
| Paperclip (standard) | Tall. | Low. | Recommended |
| Sewing needle | Very high. | Medium (injection) | Use it carefully. |
| Toothpick (tree) | Medium | Tall (crumbs) | Not recommended |
| Stationary knife | Low. | critical | Forbidden. |
| Carnation earring | Tall. | Low. | Good option. |
As can be seen from the table, metal objects with a rounded tip (clips) are preferable to sharp or fragile materials. A stationery knife is categorically not suitable, since its width often exceeds the diameter of the hole, and the risk of slipping and cutting the body or hands is extremely high.
Wooden toothpicks often break down inside the machine, and if a piece of wood stays inside, it's extremely difficult to remove it without disassembling the phone, which can cause the tray to stop opening even with the original key, so if you choose between a needle and a toothpicker, you'd better choose a needle, and you'd better be safe.
What to do categorically can not be done
In the pursuit of results, users sometimes resort to radical measures that can permanently disable the device. The most dangerous misconception is to think that if an object is not included, you need to push harder. SIM-the tray is miniature, and excessive force can lead to deformation of the internal plates or breakage of the tray itself.
⚠️ Warning: Never use glue (superglue, moment) to stick the tool to the tray! you risk pouring glue into the inside of the smartphone, after which repair will become economically inexpedient.
It is also forbidden to use electrical appliances or heating to widen the hole.Some try to heat the metal thinking it will expand, but this will damage the battery, screen or plastic elements of the case. Xiaomi uses mechanisms that do not tolerate rude interference.
- 🚫 Do not use any type of glue to fix the tools.
- 🚫 Do not use force unless the instrument is freely entered.
- 🚫 Do not try to open the tray from the screen or back cover.
- 🚫 Do not use drills or power tools.
Another common mistake is to try to tuck the tray on the back, using the gap between the tray and the frame. In modern smartphones, the gaps are minimal (less than 0.1 mm), and you are guaranteed to damage the moisture pad or scratch the frame.
What if the tip of the instrument breaks off inside?
Solving the problems: the tray jammed
There are cases where even with the right approach, the tray does not extend, which can be due to dust contamination of the mechanism or oxidation of the contacts, in which case you can try to blow the hole with compressed air (using a can of optics to clean the optics) to remove possible dust.
If the tray is pushed out but stuck halfway, don't pull it sharply. Try gently swaying it from side to side, while slightly pressing inwards, then activating the mechanism again. Sometimes it helps to tap the phone lightly against the palm in a horizontal position so that the vibration releases the jagged mechanism.
In rare cases, the problem may not be the tool, but the deformation of the tray itself, for example, if the phone has previously fallen. If you see that the tray is skewed, do not try to level it with force. Attempting to insert or pull out the skewed tray by force can lead to breakage of the motherboard, since the contacts SIM-cards can close the chain.
Prevention and advice for the future
To avoid the key-finding situation, it is recommended that you keep the original paperclip immediately after you buy your phone, and many users throw it away with the box, considering it useless, but it has the perfect diameter and shape for your model. Put it on the inside of the cover or put it in the compartment for SIM-maps, if the design allows.
If you change your SIM frequently, consider switching to eSIM if your Xiaomi model supports this technology.This will completely eliminate the need for physical interaction with the tray. QR-operator code, which is much more convenient and safer for the device body.
💡
Keeping the original key-clip in your phone case is the best prevention of tray extraction problems in the future.
And there's the hole condition, and if you notice that you're stuffing dust or lint out of your pocket, clean it with a dry soft brush, and the cleaner mechanism is more robust and requires less activation, which reduces the risk of accidental damage during operation.
