Modern smartphones of the Xiaomi brand are distinguished by a thoughtful design and reliable assembly, but sometimes users face the need to remove the tray to install a new one. SIM-The standard procedure seems elementary, but in practice, owners often find that the slot does not open in the usual way or requires a special approach. POCO They may encounter different tray designs, causing confusion among those who change the device for the first time.
In this article, we will discuss in detail all possible scenarios: from classic extraction with a paper clip to difficult cases when the tray is stuck or the mechanism breaks. You will learn how to act on the mechanism in order not to damage the body, and what actions are strictly prohibited when working with the machine. SIM-Understanding the design of your gadget will help avoid expensive repairs in the service center.
Before you start physical exposure, it is important to make sure you identify the type of tray installed in your model. Some devices support the installation of two SIM cards and a memory card at the same time, others have a combined slot. Incorrect assessment of the situation can lead to a failure of the nominating mechanism, so carefully study the features of your device before starting manipulations.
Standard procedure for tray extraction
Most Xiaomi smartphones are equipped with trays that are retrieved using a special key that comes with a kit, a thin metal needle or a plastic pin, and if the original key is lost, it can be replaced with a regular stationery clip, straightening one of the ends, or a thin needle, taking the utmost care not to scratch the case.
Find a small circular hole on the end of the device next to an oblong tray, usually located on the bottom or top of the smartphone, carefully insert the tool into the hole perpendicular to the body and press with moderate force, you should feel a slight click and spring resistance, after which the tray will extend several millimeters, allowing you to grab it with your fingers.
And when you take the tray out, you can see the shape of the tray. SIM-The cards and memory cards can be cut out to fix the cards. It is important to correctly orient the chip when installed: the bevelled corner of the card must coincide with the bevelled angle in the tray. Forced thrusting of the card is unacceptable and can damage the contacts inside the phone.
- π Find the hole for the key on the end of the smartphone case.
- π Use the original paperclip or unburdened stationery.
- π₯ Press sharply, but not too hard, until a characteristic click.
- π± Take care to pull the tray and set it up. SIM-cut-out.

If the tray is not retracted at the first press, try to slightly change the angle of the tool to get exactly into the center of the latch mechanism.
Sometimes users confuse the microphone hole with the hole to extract the tray. The microphone is usually located next to the other, but it is deeper and has no mechanical support to push. If you insert the tool and hit the "wall" without springing effect, immediately stop the pressure so as not to damage the microphone membrane.
What to do if the tray is stuck or does not open
The situation where the tray SIM-The cards are not retrieved even when pressed hard, and they are not that rare, and they can be caused by dust, by the deformation of the tray itself, or by the displacement of the internal mechanisms after the device falls. In such cases, panic and excessive force are the worst allies, as they are guaranteed to cause failure.
First, try to increase the pressure, but do it right. The tool should be inserted as deeply as possible. Try swaying the paperclip slightly left-right while pressing. Sometimes the mechanism just sours and requires a little effort to break off. However, if you feel the metal inside bends or crunch, stop.
The method with glue (only for experienced)
If the tray protrudes by a millimeter, but does not go further, you can try to use a thin tweezer or a safety razor blade to gently tamper with the edge. You need to act extremely carefully so as not to damage the frame of the smartphone. In extreme cases, if the tray is deformed, you can try to align it with a thin blade inserted into the slot, and at the same time pull out.
β οΈ Warning: Never use glue to fix a paper clip inside the hole unless you're confident in your skills. The glue that gets inside can lock the mechanism permanently, and then you'll need to disassemble the phone.
Features of combined slots
Many of Xiaomi and Redmiβs budget and mid-budget models come with a combined slot, which means you can use either two. SIM-card SIM-A microSD card and a single microSD card. The design of such trays often has two sides or special slots for cards of different sizes.
In two-way trays, one side is for SIM cards and the other is for memory cards. It is important not to confuse the sides when installing. The memory card is usually set by contacts down (or up, depending on the model), and SIM-The map is downward contacts with the key matching, and the orientation error will cause the tray to stay out of the case until the end.
βοΈ Verification of map installation
There are also models where the memory card is installed on top of the SIM-In such cases, the card or the special compartment inside the tray is first installed. SIM-A card, and then you put a memory card on it, and when you take that tray out, you can drop the cards, so hold the phone horizontally.
| Slot type | Support for SIM | Support for microSD support | Features of installation |
|---|---|---|---|
| Separate | 2 pcs. | Yes (separately) | Three independent seats |
| Combined | 2 pcs or 1 pcs. | Yes (instead of the 2nd SIM) | Choosing one of the options |
| Hybrid (old) | 1 pc. | Yes. | Rarely in new models |
| eSIM | Virtually. | Depends on the model. | Requires settings in the software |
Problems with determining the card after installation
There are times when you physically open and insert SIM-The map did, but the phone can't see it, and often the problem is that the contacts are oxidized or the card is not trimmed correctly, and if you used an old-format card and cut it with scissors, the edges could get bumpy, which prevents it from fitting tightly.
Try to clean your contacts carefully. SIM-The paper is soft, dry, and the fat and dust can create an insulating layer, and it's also recommended to check if the card is hanging in the tray, and if it has a backlash, you can cut a tiny pad out of the paper and put it on the back of the card (not on the contacts!) to ensure tight pressing.
In the software part, you should check the settings. Go to Settings. β SIM-maps and mobile networks and make sure the slot is activated. Sometimes after extraction and re-installation, you need to restart the device to initialize new hardware.
If the phone says no SIM-If you want to see a card or an emergency call, try putting it in another slot, and you can see if the problem is in the card itself, in a particular slot, or in the software of the phone, and in some cases, resetting the network settings helps.
Using eSIM on Xiaomi
Xiaomiβs current flagship models are increasingly supporting eSIM technology. Itβs an embedded digital chip that doesnβt require physical extraction or installation of a plastic card. You donβt have to open the tray to activate such a SIM. QR-code provided by the operator.
The activation process is completely in the software menu, so you have to go to the settings, select the rate and follow the instructions on the screen, which is convenient for travelers, because it allows you to quickly switch between operators in different countries without finding a clip and changing physical media.
However, having eSIM support does not negate the physical tray, and in most cases smartphones support one physical SIM and one eSIM at the same time, which gives you the flexibility to use numbers, while retaining the ability to use old carrier cards that have not yet switched to digital standards.
β οΈ Note: When you reset your phone to factory settings, the eSIM profile may be deleted. make sure you have a backup QR-code or ability to restore a profile through an operator application before formatting.
Mechanical damage and repair
If the tray is removed too easily, without the characteristic click and spring resistance, the mechanism is likely to be broken, it may be a burst spring or a broken plastic tongue on the tray itself, in which case the card will only be held by friction and may fall out when vibrating.
For a temporary solution, you can use a piece of tape or paper to fix the card in the tray, but this is not reliable. Full repair involves replacing the entire charging module (connector), since most modern Xiaomi smartphones have a connector. SIM-The card is soldered into the lower fee or is part of it.
Replacing the connector requires soldering skills and thermophene. If you don't have experience in electronics repair, you should go to a service center. Trying to solder the connector yourself can lead to detachment of the tracks on the board and failure of the smartphone.

A broken tray extraction mechanism is not a cosmetic defect, but a risk of communication loss, as the card may stop contacting the board at the slightest impact.
