Modern smartphones, including the popular model Xiaomi Redmi Note 7, are equipped with trays for the use of the smartphone. SIM-Although the procedure seems simple, many users have difficulty retrieving the tray, which may be due to the lack of a special key, stuck mechanism or trivial inattention to the details of the design.
In this article, we will take a look at all the possible scenarios you may encounter, where the extraction hole is, what you can do to replace a lost tool, and what to do if the tray is stuck inside the case, and the right approach will help you avoid damage to the internal components of your device.
Before you start to act, you need to make sure you understand the design of the slot. The Redmi Note 7 uses a combined tray, which adds its nuances to the operation. It's important to know that the tray in this model is two-way, and its improper installation often leads to a spell. Let's figure out how to act competently and safely.
Location of holes and preparation of tools
The first step to successful extraction SIM-The map is a search for a special hole. In the Xiaomi Redmi Note 7, it is located on the lower end of the case, to the left of the charging port. USB Type-C. The hole is very small and round, it is designed solely for mechanical ejection of the tray.
You'll need a special key to perform the operation, which comes with the device. If the original tool is lost, you can use a regular paper clip to straighten one of the ends of the paper clip, and the main requirement for the tool is that it must be thin enough to enter the hole, and strong enough to withstand pressure.
Do not try to use sharp objects such as needles for sewing or pins. The needle can break inside the mechanism, which will require a full repair of the smartphone in the service center. Also avoid using toothpicks, as the tree can crumble and block the mechanism permanently.
☑️ Preparation for extraction
Standard procedure for tray extraction
The process of extracting the tray in Redmi Note 7 is standardized, but requires adherence to a certain sequence of actions. Take a prepared tool (clip or key) and insert it perpendicularly into the hole. Press it confidently, but without fanaticism until you feel a slight click or spring resistance.
Once the mechanism is activated, the tray will extend a few millimeters, and then it can be gently tucked with a nail and removed completely from the body, and do not pull too hard immediately so as not to damage the contacts or the plastic frame itself.
Once extracted, inspect the tray. In Xiaomi, it often has two sides to set the cards. One side is designed for nano.-SIM, a) the second may be used for the second SIM-MicroSD cards or memory cards. make sure you correctly orient the cards when you reverse install to avoid re-jamming.
⚠️ Warning: Never try to insert the tray back unless it enters easily.Forced indentation can cause internal guides to break or damage to the motherboard.
The problem of the two-way tray in the Redmi Note 7
One of the most common reasons why users can’t reach or paste the SIM in the Xiaomi Redmi Note 7 is because of the tray design. Unlike many other models, it uses a two-way tray, which means it has two working faces, and users often confuse which side to insert it.
If you try to push the tray in the wrong direction, it just won't go in the end or it will lock halfway through. The latch mechanism won't work, and it's extremely difficult to pull it back out. The plastic can deform, giving the illusion that the tray is broken.
To avoid this error, carefully examine the extracted item. On one side there is usually a notch under the memory card, on the other - only under the SIM. When installing, make sure that you do not confuse the top and bottom. If the tray entered tightly, do not press further - you better remove it and try to flip it.
How to distinguish the right side of the tray?
What to do if the tray is stuck or broken
The situation where the tray gets stuck inside the case is critical, but it is solvable, most often because the user tried to insert it upside down, or the mechanism was contaminated with dust and pile, in such cases, a standard pressing with a paper clip may not help, as the lever rests on the obstacle.
If the tray sticks out but is not fully removed, try using a thin tweezer with soft sponges or a medical clamp. Carefully grab the visible part of the plastic and, while pressing the clip on the unlock mechanism, smoothly pull out. Sharp jerks are contraindicated here.
If the tray is completely inside and does not respond to the press, there is a risk that it has shifted to the side. Some experienced users use the "Velcro" method: a microscopic drop of superglue is dripped on the tip of a thin wire or needle, waits for a couple of seconds until the glue is grasped, and then try to carefully stretch the tray. However, this method requires jewelry accuracy to avoid sticking the tray to the case forever.
| Symptoms. | Possible cause | Recommended action |
|---|---|---|
| The tray is not moving out. | Contamination of machinery or distortion | Cleaning the hole with compressed air, neat swaying |
| The tray sticks out, but it doesn't come out. | Attempted upside-down insertion | Using tweezers for careful extraction |
| Broken plastic frame | Mechanical damage | Replacement of the tray with a compatible analogue |
| Memory card stuck | Bad card fixation or marriage | Extract together with the tray, check the size of the card |
⚠️ Warning: If you feel that the internal components of the smartphone have started to move or you hear the crackling of plastic, immediately stop attempts to repair yourself.
Alternative methods and tools
When there is no key or paper clip, users often look for tools at hand. A good alternative is a carnation earring with a thin point or a special pin for the purpose of using a carnation. SIM-The card, which you can buy at any electronics store for pennies, the main thing is that the diameter of the tool does not exceed 1.2 mm.
Some craftsmen use thin nichrome wire or string, a technique that allows not only to press the lever, but also, if you jam, to try to tamper with the edge of the tray, but using metal strings requires caution not to close contacts inside the phone if they are close to the hole.
In extreme cases, when the tray is broken inside, it may be necessary to disassemble the back cover of the Redmi Note 7. This is already a service level procedure, requiring heating the case, using suction cups and mediators to open.
Installation of a memory card and reassembly
After successful extraction of the tray and performing the necessary operations with SIM-It's important to get it back in place, make sure that the cards are in their grooves tightly and don't protrude over the edges of the frame. If the microSD card is installed incorrectly, the tray may not close until the end.
When you put the tray back in, look for the shape of the hole. The tray should come in smoothly, effortlessly. If you feel resistance, stop and check orientation. A properly installed tray becomes flush with the body, leaving no gaps.
After installation, turn on your smartphone and check the network definition. SIM-The card and the memory card, so the procedure was successful, otherwise it could be that the contacts are contaminated or the card is incorrectly installed.
💡
Before installation SIM-wipe its contacts with a soft eraser or dry cloth, which will improve the connection and prevent errors in reading the network.
💡
The key to success with the Redmi Note 7 tray is to check the orientation of the two-way frame before each insert. Don't rely on memory, always look at the shape of the cutouts.
