SIM-map. WedΕug Service center statistics, up to 15% of Redmi 8 calls are related to card tray problems, from jamming to loss of a paper clip, and 80% of the time users damage the tray during the first self-extract, without knowing the design features of the device.
In this article, you will find not only the standard photo instructions, but also alternative methods for cases when a paper clip is lost or the tray is stuck.

Preparation: What to Know Before Extracting SIM-map
Before you start the paper clip, check three key points:
- π Battery level: If the battery is under 15%, the smartphone can turn off in the process β it's not critical for the battery. SIM, but may interrupt important background processes (e.g., app updates).
- π± Check the crevice for dirt or deformities. In Redmi 8, it is located on the right end (when you look at the screen).
- π The tool type. The clip in the Xiaomi kit has a thickened tip -- if you use a stationery, you have to bend it with a loop so you don't scratch the body.
Note: Redmi 8 uses a hybrid tray (for models with two). SIM). This means that in the second slot you can insert or the second SIM-card or microSD card (up to 512 GB) and use two SIM MicroSD is not allowed, you have to choose.
β οΈ Attention: If you have dropped your phone recently or it has been in water, do not try to remove the tray yourself. Condensation may accumulate inside, and mechanical stress will aggravate the corrosion of the contacts. 20 centimeter 10-15 minutes) or contact the service.
Method 1: Standard extraction with a paper clip (Step-by-step)
This is the official method recommended by Xiaomi, suitable for all versions of the Redmi 8 (including the Redmi 8A and Redmi 8 Pro).Importantly, the clip must be metal and thin enough (no more than 0.8 mm in diameter).
- Turn off your smartphone (optional, but recommended for safety).
- Take a paper clip and insert it into the hole on the tray at a 45-degree angle to the point, and you'll feel a slight resistance.
- Press 1.5-2 kg (the equivalent of pressing the keyboard) and the tray should jump 2-3 mm.
- Carefully pull the tray with your fingers - it will completely come out of the case.
If the tray does not come out the first time:
- π Check if the stain in the hole has broken.
- π Light the gap with a flashlight - it may have got dust inside.
- π οΈ Try the other end of the paperclip (sometimes it's sharper).

In Redmi 8, the tray is fixed by a spring mechanism that can weaken over time. If you notice that the tray falls out on its own (for example, when shaking), this is a sign of wear, in which case it is better to replace the tray entirely - its article for Redmi 8: MDY10EM (cost ~ 300 rubles).
Method 2: Alternative tools if there is no paper clip
According to statistics, 40% of users lose a paper clip in the first months of using a smartphone, and fortunately, there are several safe alternatives:
| Tool. | Pluses | Cons | Level of risk |
|---|---|---|---|
| Syringe needle (0.6-0.8 mm) | Thin, strong, not bendable | Can puncture the skin with careless handling | β οΈ Medium. |
| Toothpick (pointed) | Soft, not scratching the body. | Could break inside the hole. | β High-pitched |
| Stapler braces | Strong, fitting in size. | It's hard to bend at the right angle. | β Low. |
| Scissors (tip) | Always on hand. | High risk of scratching the body | ββ Very tall. |
The most reliable option is a stapler brace, which you need to straighten and bend the tip at an angle of 30-40 degrees, and the main rule is: do not use objects wider than 1 mm, otherwise you risk damaging the tray lock.
π‘
If only a toothpick is at hand, wrap its tip with tape - this will increase the stiffness and reduce the risk of breakage inside the hole.
For Redmi 8 models with one slot for SIM (For example, some batches for the European market) the tray is shorter by 3 mm. In this case, do not apply excessive force - the mechanism is less durable.
Method 3: Removing a stuck tray (if the paperclip doesn't help)
If the tray doesn't come out after 5-6 attempts, don't keep pushing the paper clip -- you can break the lock.
- Place the smartphone down on a soft surface (such as a towel).
- Stick bilateral tape (or wide stationery) on the tray.
- Press the tape with your finger and pull it up sharply. Repeat it 2-3 times.
- If the tray has moved but does not come out completely, use a flat screwdriver (metal trays only!) Tap it on the side, but do not force it on the plastic latches.
For the Redmi 8 with a plastic tray (found in early batches), this method is not suitable - the plastic can crack.
- π§ Use the vacuum cleaner at maximum power: put the tube to the slot and turn it on. The flow of air can push the tray out.
- π§² Attach the neodymium magnet to the tray location (not the screen!) The metal parts of the mechanism will pull in and the tray will move.
β οΈ Warning: Do not use superglue or other adhesive compounds to extract the tray! the adhesive can get inside the slot and block the contacts SIM-In service centers, these cases are classified as "intentional damage", and repairs will cost a lot of money. 1500-2000 roubles (tray replacements) + purification).

- π¨ Using a knife or scissors, which causes scratches on the metal body and deformation of the retainer. In Redmi 8, the body is anodized, and deep scratches can not be eliminated.
- π¦ Wet hands - contacts SIM-The cards are oxidized by moisture, which leads to the "antenna effect" (network loss at humidity above 60%).
- π Removal when the phone is turned on - in 1 in 200 cases this causes a modem malfunction (reflashing is required).
- π± Excessive force application - the tray is fixed with a plastic tongue, which breaks when loaded more than 3 kg.
- π Frequent shifts SIM-cards β the contacts in Redmi 8 are covered with gold thickness of 0.3 microns, which is erased after ~50 extractions.
