Replacing a mobile operator, moving to another country or having to install a new SIM card are situations that every smartphone owner faces. However, in the case of Xiaomi brand devices, the procedure for removing the tray may not seem obvious to beginners, especially given the variety of models and the location of slots. Wrong actions can lead to damage to the mechanism or scratches on the body, so it is important to understand the basic principles of working with the SIM card tray.
The Chinese giant’s modern smartphones, whether budget Redmis or flagship Mis, use a standard extraction mechanism that relies on a mechanical spring pusher. Despite their apparent simplicity, users often make mistakes trying to tamper with nails or sharp objects like knives, which is strictly forbidden. In this article, we will discuss in detail how to safely and quickly extract the SIM card, what to do if the tray is stuck, and how not to confuse slots in hybrid designs.
Before any manipulation of the technical holes of the device is strongly recommended to turn off the smartphone. Although modern Hot-Swap standards allow you to change cards on the go, the software may not correctly recognize the reconnection if the extraction occurred during data recording or system processes.
Tool preparation and hole search
The first step is to find a special technological hole designed to extract the tray. In most Xiaomi models, including the Redmi Note and Mi series, it is located on one of the lateral faces of the body, most often on the lower or upper end. Visually, this tiny circular hole located next to a long narrow frame of the tray. Sometimes it can be combined with a microphone, but in this case it has a characteristic grid or is offset relative to the edge.
To act on the mechanism, you need a special tool, a key-clip, which comes with the phone. It is a metal rod attached to a plastic frame. If the original accessory is lost, it can be replaced by a regular stationery clip, straightening one of the ends, or a thin needle. The main requirement for the tool is sufficient rigidity and a sharp, but not too thin tip so as not to break inside the mechanism.
⚠️ Warning: Never use a wide-eyed sewing needle or a blunt object like a toothpick, and the needle may get stuck in the pusher mechanism, and the toothpick will simply break, permanently blocking the ability to open the tray without disassembling the body.
Make sure your hands are dry and your fingers don't slide around the body of the device. Hold the smartphone with one hand securely, fixing its position. The second hand must hold the tool confidently. It's important to direct the force strictly perpendicular to the plane of the face so as not to scratch the metal around the hole and damage the inner spring.
💡
If you have lost a paperclip from the kit, use a pin or a thin sewing needle, but act extremely carefully so as not to push the tool deeper than necessary.
Tray extraction technology
The extraction process requires precision and the right application of force. Put the tool into the hole to the point. You need to feel a slight resistance, which then will be replaced by a characteristic click or elastic push, at which point the tray should move out of the body a few millimeters, which will allow you to grab it with your fingers.
If the tray is not pushed, don't use excessive force. Try to slightly change the angle of the tool or press a little harder, but without jerking. The mechanism of the SIM ejector in Xiaomi phones is quite reliable, but requires direct action. Once the frame appears outward, carefully pull it over the edge, completely removing it from the socket.
☑️ Pre-extraction check
It is important to note that some models with waterproofing or reinforced body may require more force than in the standard versions. However, the feeling of "stuck" or creaking indicates the wrong angle of impact, in such a situation, it is better to stop trying and carefully examine the hole in good light, perhaps dust or pile.
Features of hybrid slots and Dual SIM
Many modern Xiaomi models are equipped with combined slots, known as a hybrid tray. The design of such a module allows you to install either two Nano-SIM SIM cards, or one SIM card and a microSD memory card. This solution saves the interior space of the smartphone, allowing you to make the case thinner, but requires the user to be careful when installing.
When you remove this tray, you will see two notches of different sizes or one notch with a lock for a memory card. If you plan to use only one SIM card, make sure that it is installed in the correct slot marked with the appropriate icon or number "1". Install the card in the memory slot or vice versa will cause the phone to not see the network.
What is a Dual Standby?
There is a common mistake when users try to insert a memory card into a SIM card slot, focusing only on size. The contacts and shape of the cutouts on the Nano-SIM and microSD differ, and forced installation can damage the contact areas. Always check the schematic image on the tray itself or in the instructions.
What to do if the tray is stuck or not taken out
When a SIM card tray is not removed despite the right actions, it is rare, but it can be confusing. Most often the reason lies in the deformation of the tray itself, getting dirt into the mechanism or oxidizing the contacts. If a standard pressing a paper clip does not work, do not try to pick the tray from the outside, putting it on the edge with a blade or a knife - this is guaranteed to spoil the appearance of the smartphone.
One effective method is to use glue, where a drop of superglue (literally microscopic) is applied to the end of paper clips or matches, applied to the center of the tray (without touching the body!), and wait for the tool to dry out completely, then pulled on itself in a sharp but controlled motion, a risky method that requires jewelry precision to keep the tray from sticking to the ground.
| Problem. | Possible cause | Decision |
|---|---|---|
| The tray doesn't click. | Insufficient effort or a blunt instrument | Use a sharper needle, press more confidently |
| The tray moved out, but stuck. | Frame deformation or dirt | Carefully pull with tweezers without rocking |
| The tool goes too deep. | Dust or mechanism broken | Try to push air (dangerous) or carry it to the service |
| The tray is skewed | Previous incorrect extraction | Align with a thin blade (only for experienced) |
⚠️ Attention: If the tray is jammed due to a phone drop or impact, self-extracting can damage the antenna plumes, which often pass near the slot.
Contact care and prevention
Regular removal and installation of the SIM card can lead to contamination of the gold contacts on the card itself and inside the smartphone. Oxidation or dust ingress causes signal loss, periodic network loss or complete failure of the device to see the operator. To clean contacts, it is best to use a wiltless napkin, slightly moistened in isopropyl alcohol.
It is not recommended to use water or household cleaning products, as they can leave a conductive layer or cause corrosion.After cleaning, allow the contacts to dry completely within a few minutes. It is also useful to blow the slot in the phone with compressed air to remove fine dust that may have accumulated inside the case.
Pay attention to the condition of the SIM card itself. If it has chipped, scratched contacts or a non-standard size (hand-cut), the risk of damage to the SIM card reader inside the phone increases significantly. In such cases, it is better to contact the carrier for a replacement card, since the cost of a new SIM is not comparable to the repair of a smartphone.
💡
Regular cleaning of the SIM card and slot contacts with an alcohol napkin prolongs the life of the communication module and provides a stable network signal.
