Changing a carrier or installing a new SIM card is one of the most basic tasks faced by a smartphone owner. In Xiaomi devices, this process is usually easy, since the card tray is standard design. However, inexperienced users may find it difficult to find a hole or fear of damaging the device with improper actions.
In this article, we will take a look at how to properly remove the tray, what tools will be required and what to do if the SIM card is stuck inside. We will look at the features of various models, from budget Redmi to flagship series, and pay attention to safety to avoid mechanical damage to the body of your gadget.
Preparation for the removal of the SIM tray
Before you start physically affecting the body of your smartphone, you need to make sure that the device is ready for the procedure. Although modern Xiaomi phones support hot SIM card replacement, the safest way to pre-switch off the device, this will prevent possible software failures or network identification errors after turning on.
You'll need a special tool to work with, you know, a key-clip, which comes with a phone in a box, and it looks like a thin metal needle with a plastic thickening, and if the original paperclip is lost, you can use a regular stationery, you can straighten one of its ends, or you can use a thin needle, but you need to be very careful.
It's important to find the right place to puncture. On most Redmi and POCO models, the tray is located on the bottom of the device, next to the charging connector. On Xiaomi flagship models, the slot often moves to the side edge, usually the left one, when you look at the screen. There is always a micro hole next to the hole, which is the target.
- π Find a micro hole next to the tray on the end of the case.
- π§ Prepare a metal clip, needle or special key.
- π± Turn off your smartphone or make sure itβs not in active boot mode.
β οΈ Warning: Never try to puncture a hole unless you are sure it is a SIM card slot, and there may be a noise-cancellation microphone nearby, damage to which will cause sound problems when speaking.
Step-by-step extraction instruction
The tray extraction process is universal for 99% of smartphones today, so you can hold a tool in your hand that is securely locked between your thumb and your index finger, and it will control the force of the press and prevent slipping.
Put the tip of the paper clip strictly perpendicular to the surface of the case and insert it into a micro-hole. The movement should be confident, but smooth. You will feel a slight click or resistance of the spring mechanism, after which the tray will extend a few millimeters.
Once the tray has jumped, remove the tool and pull the plastic frame with your fingers carefully. Don't pull too sharply to avoid damaging the contacts or the frame itself if it's made of thin plastic. Remove the tray completely and place it on a flat surface.
βοΈ Pre-installing check
If the tray is combined and combined with a microSD card slot, pay attention to its shape. Some Xiaomi models use a hybrid slot, where you can install either a second SIM card or a memory card in the second socket, but not at the same time.
Features of the design of different models
Xiaomi's lineup of devices is extremely diverse, and the slot's location can vary depending on the year of release and series. In budget models like the Redmi Note or Redmi A series, the tray is almost always on the bottom. It's a classic easy-to-access layout.
Flagship devices, such as the Xiaomi 13 series or Xiaomi 14, often have IP68 waterproofing. In such phones, the tray is equipped with an additional rubber seal.
There are also models with a unique design, where the tray is hidden or has a non-standard opening mechanism. In rare cases, for example, in some older models or specific regional versions, the SIM card can be non-removable or located under the back cover if it is removable.
| Series of devices | Slot location | Type of tray | Presence of water protection |
|---|---|---|---|
| Redmi Note (10-13) | Lower facet | Hybrid (2 SIM / 1 SIM+SD) | Spray protection |
| Xiaomi Mi / Digital Series | Left face | Double SIM (Nano) | IP68 (flagships) |
| POCO (M/X/F series) | Left face / Lows | Triple (2 SIM + SD) | No/Basic. |
| Redmi A/C Series | Left face | Hybrid | No. |
What to do if the tray is stuck
When the tray is not pushed after pressing the paper clip, it is rare, but can cause panic, most often the cause lies in the accumulated dust, the lint from the pocket or the deformation of the frame of the SIM card, which prevents the mechanism from working.
The first thing to do is to inspect the hole in good light, perhaps using another phone's flashlight. If you see a pile inside, try to gently remove it with a thin needle or toothpick, trying not to push the debris deeper.
If there are no visual obstacles, try changing the angle of the paper clip. Instead of strictly perpendicular input, try tilting the tool slightly up or down (literally 1-2 degrees) at the time of pressing, which can help to hook the inner lever of the mechanism.
β οΈ Warning: It is strictly forbidden to use glue to glue a SIM card to a scratcher or tray. Once inside, the glue will permanently disable the slot, and repair will be very expensive.
In extreme cases, when the tray has moved out a millimeter but stuck, you can use thin tweezers with flat edges to gently tweak and stretch the frame. Act without jerking so as not to break the plastic guides.
How to properly install the SIM card back
Installing the card requires attention to the orientation of the chip. There's always a notch on the tray in one of the corners that replicates the shape of the SIM card. Combine this notch with the rounded corner of the plastic card.
Metal contacts should look down (towards the smartphone board) if you hold the tray outside to yourself.In some Xiaomi models, contacts can look up, so always check with the icon drawn on the tray itself or on the case next to the slot.
Once the card is framed, put the tray in the phone. It's important not to turn it upside down. The tray should come in smoothly, without strong resistance. If you feel a push, don't push, take it out and flip it over.
π‘
If the tray enters tightly, check if the edge of the rubber pad is not wrapped (if any) and if the map itself is correctly oriented.
Move the tray to the characteristic click, it should match the body of the phone or slightly drown without creating stairs, after turning on the phone in the status bar, the network signal should appear.
Frequent errors and precautions
One of the most common mistakes is using tools that are too thick.The paper clip is often thicker than the original key, and using it can lead to the opening widening or the internal lever breaking.
Users often forget to check if they are activated. PIN-If you change the card on a working phone without turning off, the system may not see the new SIM immediately, and you will need to reboot to enter the pin code.
Don't ignore the state of the SIM card itself. If it's hand-cut from a larger-format card (Mini or Micro in Nano), its edges can be bumpy, and these burrs can scratch the contacts inside the phone or get stuck when extracted.
- π« Do not use blunted or rusted tools.
- π« Do not push the tray by force if it does not go.
- π« Do not leave the slot open for a long time to avoid dust.
β οΈ Warning: If you notice that the contacts inside the slot are oxidized or have a green coating after removing the tray, do not try to clean them with alcohol or liquid.
