Change of operator or installation of a new SIM-Cards are a standard procedure that every smartphone owner faces, but in the case of budget and mid-budget models like the Xiaomi Redmi 9, users often have difficulty finding the tray itself. The designers of the company decided to make the case more monolithic and hide the slots, which sometimes causes confusion among those who are used to old models with removable batteries.
Incorrect actions when removing the tray can damage the body or the mechanism itself. In this article, we will discuss in detail where the desired connector is on your device, what tools will be required and how to avoid typical errors that can cost you the warranty or integrity of the smartphone.
Before you start to physically impact the body, make sure you understand the design of your gadget.Redmi 9 has a hybrid slot, which means the ability to install two. SIM-card SIM And microSD cards, and understanding this is critical to the proper operation of the device.
⚠️ Warning: Never attempt to remove the tray with sharp objects such as needles, pins or knives.Using non-specialised tools can cause a breakdown of the mechanism or injury.
Location of the slot on the device body
The first thing you need to do is visually look at the ends of your smartphone. Unlike many modern flagships, where slots can be located at the bottom, in the Redmi 9, engineers chose a classic layout. SIM-The card is on the top end of the device, and it's standard in the Redmi line, and it allows you to easily retrieve the cards even if you have a protective case that doesn't completely cover the top face.
If you flip your phone over and you don't see an obvious hole, look carefully at the frame. The slot is a thin strip of metal or plastic that's stuck flushly in the case, and next to it should be a small circular hole designed for an ejector key. Sometimes this hole can be slightly offset relative to the tray itself, which confuses inexperienced users.
It is important not to confuse the slot for SIM-The upper end may also have an infrared port or microphone for noise reduction, and the tray extraction hole is usually smaller and located directly on the tray frame or in close proximity to the edge of the tray.
Required tools for extraction
You don’t need a sophisticated technical arsenal to perform the tray extraction operation. The Xiaomi Redmi 9 standard includes a special key-clip that is perfect in diameter and length for this hole. However, if the original paperclip is lost (which happens very often), you can use alternative tools that are found in every home.
The most affordable option is a regular stationery clip, which you need to unbend to get a straight and hard rod, and you can also use hairpins with a thin base or even thin cloves earrings, and the main requirement for the tool is that it must be strong enough to withstand the pressure, and thin enough to enter the hole without getting stuck.
- 📌 Original key-clip from the smartphone delivery kit.
- 📎 Fast forward paperclip (the most popular alternative).
- 💎 Thin hairpin or a carnation earring.
- 🔧 Specialized set of tools for electronic repair.
Using too thick objects such as toothpicks is not recommended, as they can break inside the hole, and then it will be extremely difficult to remove the debris.
⚠️ Note: If you use a homemade paper clip tool, make sure its edges aren’t too sharp to scratch the plastic around the hole when you enter.
Step-by-step instructions for removing the tray
The process of extracting the tray in Redmi 9 is as simple as possible, but requires a certain sequence of actions. First, take the selected tool (clip or key) in your hand so that you can easily control the force of pressing. Hold the tool's point strictly perpendicular to the hole on the end of the smartphone.
Carefully insert the tool into the hole to the point, you should feel a slight click or resistance of the spring mechanism, at which point you need to apply a slightly stronger but controlled force inside, while holding the phone with the second hand, the tray should pop out a few millimeters, after which it can be grabbed with your fingers.
Once the tray is removed, carefully inspect it. On the Redmi 9 hybrid slot, one side is designed for nano-SIM, and the other can be used either for a second nano-SIM or for a microSD memory card. It is important to correctly orient the cards when installed so as not to damage the contacts.
☑️ Pre-extraction check
Hybrid slot configuration and card installation
One of the key features of the Xiaomi Redmi 9 is the use of a hybrid slot, which means that you can physically fit only two modules into the case at a time. SIM-maps" or "one SIM-map + memory card: simultaneous use of two SIM The memory card in this model is impossible without the use of external adapters.
When you install a memory card or a SIM card, you need to be guided, and you usually have a diagram on the tray showing you how the card should be lying, and the contacts always point down to the board, and the cut corner of the card must match the shape of the notch in the tray, and an error in orientation can cause the card to simply not stand up or, worse, damage the contacts.
What is nano-SIM and why is it important?
To set up a microSD card in memory expansion mode, place it in the second compartment of the tray. If you need two SIM cards, the second one is installed in the same compartment, but on the back side or in a specially designated cell, depending on the tray revision. After installation, gently press the tray back into the case until the characteristic click.
Typical problems and ways to solve them
Sometimes users are faced with a situation where the tray is not removed even with a strong press, this can be caused by several reasons: contamination of the mechanism, skewed tray during the previous installation or factory defect. If a standard pressing a paper clip does not help, try swaying the tool slightly from side to side, while pressing inwards.
Another common problem is that the tray popped out, but it got stuck halfway and it's not pulled out by your fingers, in which case you can use a thin tweezer with blunt ends or a sticky tape to pull it out neatly, and the main thing is not to use excessive force that can bend the metal frame.
If the tray is removed too easily and not fixed inside the case, the internal spring mechanism may have broken or plastic guides have deformed, in which case repair is required at the service center, since self-repairing the fixing mechanism requires disassembling the device.
| Problem. | Probable cause | Decision |
|---|---|---|
| The tray is not moving out. | Clogging of a hole or blunt instrument | Use a thinner paper clip, clean the hole |
| The tray is stuck halfway. | Disproportionately with previous installation | Carefully pull out with tweezers, check the guides |
| Phone can't see SIM | Incorrect installation or oxidation of contacts | Translate the map, wipe the contacts with a lastic |
| The tray falls out on its own. | Damage to the striker | Replacement of the tray or repair of the mechanism in the service |
💡
If the tray is difficult to remove, try tapping the end of the phone slightly on your palm when you press the paperclip, and the vibration can help to release the jammed mechanism.
Care for the slot and prevention of breakdowns
To make the extraction mechanism last long and not cause problems, it is necessary to follow simple rules of operation. Dust and small debris, getting into the hole for the paper clip, can be compressed and block the movement of the tray. Regularly, at least once every few months, it is recommended to blow the ends of the smartphone with compressed air or clean them gently with a soft brush.
It is also important to monitor the condition of themselves. SIM-If a memory card or SIM card has chipped, burrs, or deformities, it can scratch the tray's internal contacts or get stuck when extracted. Using non-standard thickness cards (such as those with plug-ins) is one of the main reasons for tray failures in Redmi 9.
When installing a protective case, make sure it does not block access to the top end of the device.Some tight silicone bumpers can displace the tray or interfere with the entry of the paper clip into the hole, which creates unnecessary stress on the plastic of the case.
💡
Regular cleanliness of the ends of the smartphone and the use of cards of the correct shape is the best prevention of problems with the slot SIM-map.
⚠️ Warning: Avoid getting moisture into the paper clip hole. Water can cause contacts inside the case to oxidize, resulting in signal loss or short circuit.
