Procedure for replacing a mobile operator or installing a new one SIM-The cards seem rudimentary until you encounter a custom tray design or a stuck stub. owners of Xiaomi, Redmi and Poco devices often wonder about the right algorithm of actions so as not to damage the delicate extraction mechanism. Modern smartphones are equipped with compact slots that require careful handling of a special tool.
Misuse of foreign objects can damage contacts or even break the body of the device. In this article, we will discuss how to safely remove the tray without damaging the moisture seal, and consider the nuances for various series of smartphones. It is important to understand the design of your gadget before starting any manipulation with the hardware.
We will not only look at standard scenarios, but also at situations where SIM-The card is stuck or the tray is not opening, and knowing these subtleties will help you avoid costly repairs at the service center, and let's figure out what tools you need and what you absolutely can't do in the process.
Preparation of the workplace and necessary tools
Before you start retrieving the map, you need to organize the right workspace. You need a well-lit table with a flat surface to make small parts like the one you're looking at. SIM-A map or a paper clip, not rolled into hard-to-reach places, and a lost tray in a carpet or under a sofa would be extremely problematic, so foresight is key here.
The main tool is a special metal clip that comes with a smartphone box. If the original paper clip is lost, you can use a thin needle or straightened stationery clip, but you need to act with utmost care. Office paper clips are often too thick and can get stuck in the hole, blocking the mechanism permanently.
⚠️ Warning: Never use knives, sewers or other sharp objects with a wide blade to remove the tray, which can damage the internal contacts or tear the sealing gum responsible for protecting against dust and moisture.
It is also recommended to prepare a soft cloth or napkin on which you will put the extracted tray.This will prevent scratches on the plastic frame and protect the contacts of the card from static electricity that can accumulate on synthetic surfaces.
Determination of the type of tray and slot location
Xiaomi smartphones are available with various modifications of slots for SIM-It's important to know exactly what type of card you have in your model, and most commonly, you'll find a combined tray that allows you to use two nano-SIM cards or one. SIM The location of the extraction hole varies: in most modern models, it is located on the lower end of the device, next to the charging port.
However, in some older or specific models, such as individual versions of the Redmi Note or Mi Pad tablets, the slot can be located on the side of the side. Carefully examine the perimeter of the body, a narrow elongated slot with a tiny hole in the middle.
There is also a hybrid tray where the second cell is designed for either a second SIM or a memory card, but not both at once.The design of such trays often has two independent parts or latches. Understanding the type of tray will help avoid situations where the user tries to insert a memory card into a SIM slot, which can lead to a jamming.
Step-by-step extraction instructions SIM-map
The extraction process requires precision and confident movement. First, take the tool (clip) and make sure that the end of the tool is straight and has no barbs. Insert the tip of the clip strictly perpendicular to the hole at the end of the case. Don't be afraid to press a little harder than you think you need, but do it smoothly, feeling the resistance of the spring mechanism.
Once you feel a slight click and see that the tray has moved a few millimeters, stop pressing. Carefully tuck the plastic frame with your nails and completely remove it from the body. Sharp movements can cause the tray to fly out along with the map and fall to the floor.
☑️ Extraction algorithm SIM
If the tray is not removed after the first press, do not use excessive force. Try to change the angle of inclination of the paper clip by a couple of degrees or slightly rotate it around the axis. The mechanism can simply be slightly jammed with dust or oxidation, and a slight change in the force vector will help move it from place.
⚠️ Warning: If the tray is stuck dead and resists effort, do not try to pull it out with pliers or tweezers.You risk crumble the plastic tray or damage the side frame of the smartphone, which will make further extraction impossible without disassembling.
After successful extraction, inspect the tray for contaminants. If you plan to replace the card, carefully remove the old nano-SIM from the plastic frame and install a new one, observing the orientation of the cut. The contacts of the map should be directed downwards, and the cut corner usually coincides with the shape of the tray.
Features of the design of different Xiaomi series
Different Xiaomi smartphone lines have their own design features that affect the extraction process. SIM-For example, the Mi and Xiaomi series (the flagship models) often use waterproof trays with a double rubber seal. These trays sit very tightly, and it may require a stronger but more careful pressing of the clip to extract them.
In the Redmi and Poco budget series, the design can be simpler, without complex seals, but the plastic tray is often more fragile. It is important not to overdo the pressure here so as not to break the thin partitions inside the tray itself. Also, in some Redmi models, there is a triple slot where the space for two SIMs and memory cards are physically separated.
| Series of devices | Type of tray | Location. | Features |
|---|---|---|---|
| Xiaomi Mi / Digital Series | Combined (Nano + Nano) | Lower end | Tight moisture sealer |
| Redmi Note | Hybrid (Nano + Nano/microSD) | Lower end | Plastics that require precision |
| Poco X / F series | Individual slots or combos | Lower end | Often lacks in water protection |
| Older models (Mi 4, 5) | Micro-SIM / Nano-SIM | Side-face | Mechanical latch |
The older models, where the slot could be located under a removable back cover, require that devices like the early Redmi first remove the lid and remove the battery to access the slot, which is less convenient but eliminates the risk of damage to the side faces of the case when removed.
What to do if the tray is curved?
Solving Problems: A Stuck Tray and Other Difficulties
One of the most common problems is that the tray gets stuck inside the case and is not removed in the standard way, and this can be due to dust, sand or deformation of the tray itself. In such cases, you can try the "scotch" method: stick a strip of wide tape sticky side to the tray opening, leaving the tail, and sharply pull. This method works if the tray is even slightly outwards.
If you can't see the tray at all, you can try to gently sway the device horizontally while pressing the paper clip, sometimes tapping the edge of the hand on the end of the smartphone in the slot area helps to shake off the dust blocking the mechanism, the main thing is to avoid hitting hard surfaces.
💡
Lubricate the mechanism with the alcohol droplets. If the tray is jammed due to oxidation, a drop of isopropyl alcohol applied to the paper clip and inserted into the hole can dissolve the contamination and facilitate extraction.
In extreme cases, when software and simple physical methods do not help, only an appeal to the service center remains. Self-disassembly of a smartphone to access the slot from the inside requires special tools and skills, and also carries the risk of loss of warranty and damage to the plumes.
Care for the slot and prevention of malfunctions
How to avoid problems with extraction SIM-In the future, it is recommended to follow simple rules of operation. Regularly wipe the end of the smartphone with a soft cloth, removing dust and pile that can get into the hole for the paper clip. Cleanliness in the pocket or bag also plays a role: avoid carrying the phone along with small debris.
Replacement SIM-Always turn off the device, although modern standards allow you to do it “hot.” However, for Android devices, especially with two active cards, the program reset network when the phone is turned off is more correct and prevents possible errors of reading the contact.
⚠️ Note: Do not leave the slot open for a long time without SIM-It can get moisture or dust inside the device, causing the motherboard contacts to oxidize and costly repairs.
If you change cards frequently, it makes sense to buy a special adapter or holder so you don't lose the original paper clip, and you can also take a picture of the correct orientation of the card in the tray, so that the next moment of the replacement, you don't know which side to insert it.
