Modern smartphones Xiaomi is famous for its design and functionality, but new users often have a question about the physical location of the slot for the game. SIM-Unlike older models with removable covers, current devices require careful handling of the case.
In this article, we will take a closer look at where exactly the place to install the communication module in different phone series, including Redmi, Poco and the flagship Mi line. You will learn about the types of trays, the differences in the design of different generations of devices and the features of combined slots. This knowledge will help you avoid typical errors and quickly activate your number.
Before you start installing, it's important to understand that the design of the socket depends on the year of release and the price segment of the gadget. Some models are equipped with a hybrid connector, which imposes restrictions on the simultaneous use of two SIM cards and a memory card. We will look at all the nuances so that you can confidently manage your device.
Types of trays for SIM-cards in Xiaomi smartphones
The first thing that the owner encounters when trying to find a slot is the lack of visible slits on the case. Xiaomi engineers use hidden trays that are only retrieved using a special tool. There are two main types of design that determine where the hole is physically located and what it looks like.
The classic version is a narrow slot on one of the ends of the device, usually equipped with a micro-hole for the needle. In more modern or budget models, a combined tray is found, in which case the hybrid slot allows you to choose between using two SIM cards or one SIM card plus a MicroSD memory card.
- 📱 Separate tray: Two independent nests for two SIM and one for a memory card (found less frequently in new models).
- 🔄 Hybrid slot: The second slot is divided between the second SIM and a memory card, cannot be used simultaneously.
- 🚫 Lack of slot: In some versions of the markets, the slot may be soldered or missing (extremely rare).
💡
Always check the box before buying – in some regions Xiaomi supplies devices without a paper clip in the kit, using a plug instead.
It is important to note that trying to open the tray without using a special key or a thin needle can damage the mechanism.The mechanical key (clip) usually comes in the kit, but it is easy to lose.If there is no original tool at hand, use a thin needle for sewing machines, but avoid using stationery clips, as they are often too soft and can bend inside the case.
Location of the slot on different models of Redmi and Mi
Finding a tray extraction hole depends on the specific series of devices. In most cases, manufacturers have standardized the arrangement of elements, but there are exceptions, especially in models with unusual form factor or moisture protection.
In classic Redmi Note smartphones and the baseline Redmi lineup, the slot is almost always located on the top end of the case. This ergonomic solution allows you to extract the card without removing the case if it does not completely cover the ends.
Flagship models of the Mi series (now Xiaomi number series) often have a tray located on the bottom end, next to the USB Type-C connector and speaker.This is done to improve the tightness and weight balance of the device. In foldable models such as the Mi Mix Fold, the slot can be on the side face opposite to the control buttons.
If you can't find the hole, look carefully at all the faces in good light. Look for a small round dot about 1 mm in diameter. Sometimes it can be disguised as the color of the case or have a barely noticeable edge. In IP68 moisture-proof devices, the tray sealant can sit very tightly, requiring more confident but neat pressure.
Step-by-step instructions for extraction and installation
The process of replacing the communication card requires care not to damage the contacts or the tray itself. Before the procedure, it is strongly recommended to turn off the device, although modern smartphones support hot replacement. Shutdown ensures that the system correctly reconnects to the network and reads the new operator settings.
Find a hole on the case and insert a needle perpendicular to the surface. Press until the characteristic click and easy extension of the tray. Don't put too much effort: if the tray doesn't come out, you may not have hit the latch mechanism or you may have used a blunt tool.
☑️ Proper installation SIM-map
After you remove the tray, notice the shape of the tray. You need to place the SIM card in the notch so that the bevelled angle matches the marking on the tray. The contacts of the metal plate should look down to the inside of the phone. Misplacing the card with the contacts up can lead to short circuits or no signal.
⚠️ Warning: Never put a tray in your phone if it's not in it SIM-Dust and moisture trapped inside an empty slot can oxidize the motherboard contacts, leading to costly repairs.
Put the tray back in smoothly, without skewing. It should enter the case before clicking or before full comparison with the phone frame. If the tray sticks out even a millimeter, it breaks the tightness and can damage the side button or plume when carried in your pocket.
Features of hybrid slots and memory cards
Many users wonder why the second slot doesn't read the second SIM card after the flash drive is installed. The answer lies in the design of the hybrid slot. In such models, the second seat is physically one, and it can receive either a communication module or a drive.
If you need to use two SIM cards and a memory card at the same time, you will have to give up one of the SIMs or use cloud services to store data instead of a physical card.Some users resort to cutting memory cards to the size of the SIM, but this is an extremely risky method that can lead to the card getting stuck inside the phone.
| Slot type | Slot 1 | Slot 2 | Slot 3 (separate) |
|---|---|---|---|
| Triple (rare) | Nano-SIM | Nano-SIM | MicroSD |
| Hybrid | Nano-SIM | Nano-SIM or MicroSD | No. |
| Double SIM. | Nano-SIM | Nano-SIM | No. |
| eSIM + SIM | Nano-SIM | eSIM (virtual) | No. |
What to do if you need a second sim and a memory card?
When using a hybrid slot, Android usually warns the user of a conflict when installing a new card. However, the physical installation requires understanding what type of card you are prioritizing. In eSIM-enabled models, the second slot can be reserved for a virtual profile, which also limits the expansion options.
Problems with recognition SIM-map
There are times when the card is installed correctly, but the phone says "No network" or"SIM-The problem is often oxidation of the contacts of the card itself or contamination of the reader in the phone. Carefully wipe the golden contacts of the SIM card with a soft eraser or cloth soaked in alcohol.
Another common reason is form factor incompatibility: Older hand-cut Mini-SIM or Micro-SIM cards may be incorrectly thick or misaligned contacts, and in such cases, it is better to contact the operator's salon for a free replacement with the current Nano-SIM format.
If the phone sees the map but doesn't catch the network, check the settings in the menu. → SIM-Make sure the card activation slider is on, sometimes manual operator selection or resetting the network to factory settings helps.
⚠️ Warning: If after installing the card, the phone starts to discharge rapidly or heat up in the upper/lower end area, immediately remove the SIM card.
Using eSIM in new Xiaomi models
Modern flagships Xiaomi increasingly equipped with eSIM technology. it is an embedded chip that does not require a physical slot. to activate such a tariff, you do not need to look for a hole in the case - all settings are made software through scanning. QR-operator-code.
Having an eSIM doesn't negate having a physical slot, but it complements it.You can have one physical number and one virtual one by switching between them in settings.This is especially convenient for travelers who can buy local fares without buying plastic cards.
💡
The eSIM technology eliminates the need to search for a paper clip and open the tray, allowing you to activate the number in a couple of minutes through the system settings.
What to check before switching to eSIM? Make sure your carrier supports this technology and that the phone model you bought has the appropriate hardware support (China versions may differ from global ones). The Settings → Connections and Sharing menu should have the option to add a virtual card.
