How to open the tray for SIM-maps in Xiaomi Redmi 9C: 3 proven methods + quirky

Slot for SIM-maps in Xiaomi Redmi 9C — It seems to be the simplest element of a smartphone, but its incorrect opening can lead to jamming of the mechanism, damage to the contacts or even cracks in the body, especially for beginners who try to tray with a knife, needle or other improvised means. In this article, we will discuss three official extraction methods (including the paper clipless method), explain why the tray may not be retracted even with the right actions, and show how to avoid breakdowns when installing a nano-SIM or memory card.

The Redmi 9C (codenamed angelica) features a hybrid slot that supports either two nano-SIMs or one nano-SIM + microSD up to 512GB. The tray design here is typical for budget Xiaomi: it is fixed by a spring mechanism, and the extraction hole is located on the top edge (if you look at the screen). However, even knowing this, many users are faced with the fact that the slot “sucks” or does not respond to the press of the paper clip.

1. Standard method: paper clip or tool from the kit

The most reliable and recommended method by the manufacturer is the use of a special key to extract the key. SIM-The tray that comes with Redmi 9C. If it is not at hand, an unbended stationery clip with a diameter of no more than 0.7 mm will fit. Importantly, do not use pins, needles or toothpicks - they are too thin and can break inside the hole.

Algorithm of action:

🔍 Find the hole to extract, located on the top of the smartphone (near the power button), marked by a small dot or inscription. SIM.
📍 Insert the paper clip at 90 angle° Press hard, but not bigotry, and it's got to be a little click.
🖐️ Take out the tray. Once you click it will move 1-2 mm -- pull it with your fingers to the end.

Turn off your smartphone (optional, but recommended for safety)|Make sure the paperclip is not bent and has no burrs.|Make sure the hole is not covered with dust.|Keep your phone upwards so that the tray does not fall out.-->

If the tray is not pushed, do not put too much effort!

🔧 The mechanism jammed due to moisture or dust.
🔄 The paperclip is too thin and does not press the locker.
📱 The phone fell and the tray deformed.

💡

If the paperclip does not enter the hole, try to slightly twist it clockwise - sometimes this helps to "find" the fixture.

2. Alternative methods: without paper clip and by available means

There are different situations: the key is lost, the paper clip is not available, and the slot needs to be opened urgently, in such cases, alternative methods can be used, but they require caution.

Method 1: Tape or thread

A thin capron thread or scotch 5-10 mm wide will do.

Cut a piece of thread 15-20 cm long.
Fold it in half and put a loop in the clip hole.
Pull both ends at the same time - the loop will hook the lock and stretch the tray.

⚠️ Warning: Do not use coarse rope or laces - they can scratch the body or break the mechanism.

Method 2: Disassembly of the body (extreme case)

If the tray is jammed and no method works, you only have to disassemble it in a partial way, which is risky and voids the warranty, but sometimes it's the only way out.

🔧 Plastic blade or mediator.
🔥 Fryer (for softening glue).
🧲 Screen removal suction cup (optional).

Instructions:

Find the locking mechanism. SIM-tray (usually a metal plate with a spring).
Carefully press the spring with a screwdriver, while pulling the tray.

What to do if the tray fell out of the grooves?

If the tray is completely out of the guides, do not try to insert it back by force! First check: 1. Condition of the spring of the lock (it should be whole and elastic). 2. No debris in the slots. 3. Correct position of the tray (contacts should be on top). If the spring is broken, it can be replaced at the service center (repair cost ~ 300-500 rubles).

3. Common mistakes and how to avoid them

Even experienced users sometimes make mistakes when working with the Internet. SIM-Here are the most common of these and how to prevent them:

Mistake.	Effects of consequences	How to avoid
Use of sharp objects (knife, needle)	Scratches on the body, breakage of the fixator	Use only a paper clip or a special key
Pressing the paperclip too hard	Deformation of the spring or failure of the thread in the hole	Press smoothly, no jerks
Installation SIM-wrong-side	Contact damage, "No network" error	The cut corner of the card should coincide with the angle of the tray
Getting moisture into the slot	Corrosion of contacts, jamming of the mechanism	Dry your phone before removing the tray

Pay special attention to mounting the tray back. It should enter the slots without effort - if you feel resistance, check:

📱 Correct location SIM-maps (contacts down!).
🔄 No garbage in the slot.
🔧 Integrity of sealing gum (if the phone is waterproof).

4. What to do if the tray is jammed?

If the slot is SIM-The card doesn't respond to the press of the paper clip or it doesn't fully push, don't panic. 80 percent of the time, you can solve the problem without disassembling:

Blow the hole. Sometimes debris or dust blocks the mechanism, use a spray of compressed air or just blow a lot.
If it's halfway out, gently pull it up and down while pressing the paper clip.
Heat the case. If the phone was in the cold, the condensate could cause corrosion. Put it in a warm place for 10 to 15 minutes, then try again.
Use a vacuum. Apply a vacuum cleaner at minimum power to the hole, which sometimes helps to pull the tray out.

⚠️ Note: If the tray is not removed after all the manipulations, do not apply force - this can break the lock. Contact the Xiaomi service center or workshop, where there is a tool for safe extraction. The average cost of the service is 200-400 rubles.

💡

If the tray is jammed after the phone falls, there is a high probability of deformation of the metal frame, in which case disassembly is inevitable - you can not solve the problem yourself.
