How to safely pull out SIM-Map from Xiaomi Redmi Note 9: instructions with photos and videos

In this article, we will discuss not only the standard method, but also alternative methods in case a regular tool is missing, and also tell you how to avoid the typical errors that can lead to the breakage of the SIM-tray or even the motherboard.

Important: The design of the tray in the Redmi Note 9 (models M2003J15SC, M2003J15SS, etc.) differs from newer versions - for example, the Redmi Note 10 or Note 11. It uses a hybrid slot that supports either two nano-SIMs or one nano-SIM + microSD. This imposes restrictions on card combinations.

Where is the slot for SIM-Maps in Redmi Note 9

Unlike some Samsung or iPhone models, where the slot can be placed on top or even on the back, in the Xiaomi Redmi Note 9 it is located on the left end of the case, more precisely, between the volume buttons and the card tray.

Visually, it's easy to recognize by the pinhole and the contour of the plastic tray, and the "SIM" or the icon of the card is usually missing -- it's done for a minimalist design. If you hold the phone with the screen to you, the slot will be on the left, about half the height of the case.

If you are not sure you have found the slot for SIM-map, pay attention to its dimensions: the hole for extraction has a diameter of about 0.8 mm, and the tray itself protrudes over the body by 0.3-0.5 mm.

Step-by-step: how to pull out the tray for SIM-map

Now, to the process itself, follow the instructions carefully so that you don't damage the locking mechanism.

1. Turn off the phone (optional, but recommended) to prevent accidental taps on the screen and reduce the risk of short circuit if moisture or metal particles get inside.
2. Take the key to extract (or a paper clip) and gently insert it into the hole next to the slot. Press with a force of 1-1.5 kg, it should sound a slight click.
3. Once you click, the tray will move 2 to 3 mm. Carefully pull it with your fingers until it is fully removed. Do not use force - if the tray is not coming, check if it is jammed due to dust.
4. Extract. SIM-card(s) or microSD. Pay attention to the position of the contacts – they should be directed downwards (to the back cover of the phone).

If the tray does not extend after pressing the key, try to sway the tool slightly left-right or push at a different angle. Sometimes the mechanism will sour due to oxidation, in which case WD-40 will help (apply minimally so as not to damage the contacts).

💡

If the key is lost, use an unbended clip or needle from the syringe, the main thing is that the diameter does not exceed 0.8 mm, otherwise you can damage the fixation mechanism.

Frequent Mistakes and How to Avoid Them

Even with this simple procedure, users manage to make mistakes that lead to breakdowns, and here are the most common ones:

• 🔨 Pressing the key too hard can break the spring mechanism inside the slot.
• 🔄 Turning over SIM-cards -- contacts must be facing the back cover, and if you put the card upside down, the phone won't recognize it.
• 💦 Getting moisture into the slot - if the phone is wet, dry it with a hair dryer (cold air!) or silica gel before extracting the card.
• 🔌 Using inappropriate tools – toothpicks, knives or forks can scratch the body or jam the tray.

⚠️ Note: If after removal SIM-If you're not using a card, you can check the integrity of the contacts on the tray, sometimes they bend when you're not handling them properly, and you can use a plastic card (like a bank card) to align, but not metal objects!

Another common problem is a jammed tray after the phone falls, in which case, don't try to pull it out by force, because it can tear the plume off the motherboard, but you should go to a service center where specialists will disassemble the case and remove the tray without risk.

Alternative methods of extraction SIM-map

What if you don't have a key or a paper clip on hand? There are several alternative methods, but they all require caution.

Method 1: Use of headphones with a 3.5 mm connector

If you have a 3.5mm jack headphone, you can try the following:

1. Cut the plug off the wires, leave only the metal tip.
2. Then put it in the hole and put it in the hole.
3. As soon as the tray is pushed out, tuck it with a nail or a plastic card.

Method 2: Application of the vacuum method (for experienced users)

This is a good way to do it if the tray is halfway out but stuck.

1. Turn the vacuum cleaner on at minimum power.
2. Bring the nozzle to the gap between the tray and the body.
3. The vacuum should "stretch" the tray by several millimeters - after that it can be tampered with.

⚠️ Warning: Do not use this method if the phone was in water or humid environment! airflow can drive moisture deeper into the case, which will lead to corrosion of contacts.

Method 3: Disassembly of the body (extreme case)

If the tray is jammed so much that no methods are working, then you only have to deconstruct it in a partial way.

1. Remove the back cover (need a mediator or plastic shoulder blade).
2. Unscrew the screws fixing the metal plate over the tray.
3. Carefully tuck the tray on the inside.

This method requires skills and is only suitable for the Redmi Note 9 with a collapsible body. In models with adhesive attachment (for example, the Redmi Note 9T), it is better not to take risks.

💡

If the tray is not removed by any means, do not make excessive efforts - contact the service. The cost of repairing the slot (300-800 rubles) is much lower than replacing the motherboard due to a plume break.
