Owners of Xiaomi Redmi 9 often face this problem, as complete with budget devices, the clip is sometimes not available, or it is easily lost.

Fortunately, the design of the tray in this model does not require specific engineering knowledge or sophisticated access equipment. The mechanism here is standard in the industry, and it can be activated with almost any thin and hard object, the main thing is to act carefully so as not to damage the inside of the device or the memory card itself, which is often in the neighborhood.

Anatomy of the SIM tray in Redmi 9

The extraction mechanism is based on a spring-loaded latch. Inside the narrow hole on the bottom end of the body is a lever. When you insert a foreign object into it and press it, the lever pushes the tray outward. The hole in Redmi 9 has a standard diameter, which makes it easier to find alternative tools.

⚠️ Warning: Never try to insert tools into other holes on the case! near the tray SIM There may be a microphone or speaker, damage to which will result in expensive repairs.

The slot's location in Redmi 9 is classic, it's on the bottom of the device, next to the USB Type-C connector. To avoid confusion, just look at the end: the tray has a clear oblong shape with a small circular hole in the middle of one of the narrow sides.

Selection of safe tools from available means

The most obvious and frequently used option is a regular stationery clip. However, not every paper clip will be perfect. For the Xiaomi Redmi 9, the best option is to use medium-sized clips made of fairly rigid, but not brittle wire. Too thin wire can bend inside the mechanism, and too thick wire can get stuck.

Another great option is the sewing needle, which is probably the most reliable tool after the original key, the needle is perfect thickness and strength, but there's a caveat: the needle is sharp, and there's a risk of hurting or scratching the body, and if you use a very thin needle, it can pass through the hole without hitting the lever if you don't press it at a right angle.

  • πŸ“Œ Paperclip: Unwind one end at a 90 degree angle to get a straight rod.
  • πŸ“Œ Needle: Use a medium-sized needle, holding it perpendicular to the body.
  • πŸ“Œ Carnation earring: The pin from a cloves earring often has the perfect thickness for such tasks.
  • πŸ“Œ Toothpick: Wood or plastic (metallic can break), but only as a last resort.

You can also consider using a thin wire from headphones if it has a hard metal core, or even pins. The main requirement for the tool is that it must be hard, not bend with moderate pressure and have a diameter comparable to the hole. Plastic objects such as the rod of the handle are usually too soft and can break inside, blocking the mechanism.

Step-by-step: how to remove the tray

The process of removing the tray requires calmness and precision. Don't rush or put too much effort into it. First, prepare the workplace: select a surface with good lighting so you can clearly see the small hole. Put the tool in front of you.

β˜‘οΈ Pre-extraction check

Done: 0 / 4

Take a tool (like an unbended paperclip) and hold it to the hole strictly perpendyar to the face of the smartphone. Don't tilt the tool left or right. Smoothly but confidently push inside. You should feel a slight click or resistance, which will be replaced by the movement of the tray outwards.

Once the tray is pushed a few millimeters, pull the tool away and pull it gently with your fingers. Don't pull it out. If the tray doesn't come out after you first press it, try changing the angle of the tool by literally a degree or using a thinner object. Sometimes dust gets into the hole that interferes with the mechanism.

⚠️ Warning: If the tray is stuck and does not respond, do not use force. Try tapping the phone with your rib on your palm to slightly shift the internal components, or use a drop of isopropyl alcohol to clean the mechanism (only if you are confident in your actions).

Once you've successfully extracted it, you'll see two sites: one is for nano-SIM, the other is universal. Pay attention to the bevelled corner of the card, it tells you if you're putting the SIM card on the right side. In Redmi 9, it's important not to confuse the slots, although it's physically difficult to insert the card incorrectly due to the shape of the cutout.

What to do if there are no tools at hand

There are situations where there's no paper clips, no needle, no pins around, like you're outdoors or away, and you can be smart, and one way to do that is to use a thin strip of electronics, or even a tight cardboard rolled up into a tube, but this doesn't always work, because cardboard can be too soft for the spring of the tray.

If you're at home and you can't find any metal objects, try finding thin wire from an old charger (if it sticks out of the insulation) or even using a bracelet clasp. In extreme cases, you can gently break off the tip of a plastic toothpick, sharpen it and try to use it. But remember, the plastic can crumble.

If you lose paper clips frequently, stick one magnet to a prominent place in the hallway or keep the original phone key in a case if the design permits.
