Changing carriers or installing a new Micro-SIM is often a necessity, but Xiaomi smartphone owners sometimes face unexpected difficulties. The question of how to get a Xiaomi Redmi Note 9 SIM becomes especially relevant when the standard method using a paper clip fails or causes fears of damaging the device.
In this article, we will take a look at all the ways to extract the card, from regular to emergency, applicable in situations where the tray is jammed. You will learn why the ejection mechanism may not work and which tools are really safe for the case of the smartphone. The main rule is never use sharp metal objects like sewing needles, as they can break inside the hole.
Before you start to act, you need to completely turn off the device and prepare the workplace with good lighting. Understanding the design of the end socket will help avoid mechanical damage to the housing, which can lead to loss of warranty. Let's look at the standard algorithm of actions, which is suitable for 95% of cases.
Standard tray extraction algorithm
The process of replacing the card in Redmi Note 9 begins by looking for a special hole on the bottom end of the device, located between the USB Type-C connector and the speaker, as well as a headphone jack. To extract, a special metal clip that comes with the kit, or a similar tool with a diameter of about 1.3 mm, is used.
Insert the paper clip into the hole strictly perpendicular to the edge of the body and press with moderate force until the characteristic click. The spring ejection mechanism should work, and the tray will extend a few millimeters, after which it can be gently tucked with the nail. If you feel resistance, but the click is not, perhaps you are not pressing hard enough or, conversely, the angle of the tool is incorrect.
💡
Use a paper clip from Xiaomi's original box - it has the perfect length and thickness.Stock clips are often too thin and can bend, getting stuck inside the mechanism.
After extraction, note the labeling inside the tray that indicates the correct orientation of the chip. This model uses a hybrid slot where the second cell can be occupied by a microSD memory card. It is important not to confuse the position, as improper installation can lead to the fact that the device will not see any of the cards.
What to do if the tray is stuck or not taken out
When the tray is not amenable to standard extraction, it is less common, but requires special approach and coolness. Often the cause is the accumulation of dust, pile or oxidation of contacts, which blocks the movement of the mechanism. In such cases, a simple effort can lead to breakage of the plastic frame of the tray, so you need to act carefully.
The first step is to try tapping your smartphone gently with the edge of your hand in the lower end, turning it downwards with the connector, which can help displace stuck dust or micro-junks that block your path. Also effective is to use insulating tape or tape: stick a small piece to the end of the tray (if it is even slightly visible) and sharply pull on yourself.
⚠️ Warning: Never try to pick a tray with a knife or blade, inserting it into the gap between the frame and the body.This is guaranteed to cause chips on the frame and can damage the moisture-protective pasting.
If mechanical stresses don't work, you can try the software method, although it doesn't work on all versions of MIUI firmware. Some users have noted that turning on USB debugging mode or performing a setup reset (pre-backup) can initiate a port request, which sometimes unlocks the mechanism.

Tools and workplace preparation required
For the safe conduct of the extraction operation SIM-The presence of the right tools reduces the risk of damage to the Xiaomi smartphone to a minimum.It is important that all tools are clean and dry, so as not to put dirt inside the case.
Here is a list of what you may need in the process:
- 📌 The original paper clip for SIM or a quality analogue of hardened steel.
- 💡 Powerful lamp or table lamp for good lighting connector.
- 🔍 A magnifying glass or magnifying glass if you have vision problems to see the mechanism inside.
- 🧤 Antistatic gloves (optional) to avoid leaving greasy marks on contacts.
Prepare a flat surface covered with soft cloth in case the tray crashes and falls. It is also recommended to have isopropyl alcohol on hand to clean the contacts if you plan not only to replace the card, but also to service the connector. Working in good light will immediately notice small details, such as cracks on the plastic tray.
☑️ Testing of recovery readiness
Design features of the Redmi Note 9 hybrid slot
Redmi Note 9 is equipped with a hybrid slot, which means the possibility of installing either two. SIM-card SIM This solution allows you to save a thin case of the device, but imposes restrictions on the simultaneous use of three cards.
The tray has two sides: one is the main one. SIM-A Nano-SIM card, and the other one is either a second Nano-SIM or a memory card. The slots are shaped in a specific way that prevents the card from being placed on the wrong side, but requires precise positioning. An installation error can cause the tray to simply not fit into the case until the end.
Below is a map compatibility and location table for your model:
| Position in the tray | Type of card | Format | Note |
|---|---|---|---|
| Slot 1 (external) | SIM / MicroSD | Nano-SIM / MicroSD | The main slot for the network |
| Slot 2 (internal) | SIM | Nano-SIM | Second number or memory |
| Contacts | Gold. | - | Headed upwards |
When installing, make sure that the cut corner of the card matches the marking on the tray. SIM-Cards (such as the Mini-SIM in Nano-SIM), be especially careful: such designs are often thicker and can get stuck inside the phone, locking the mechanism permanently.
Common Mistakes and How to Avoid Them
Many users make the same mistakes when trying to replace a card quickly, which backfires. The most common is trying to push the tray by force if it doesn't come in the first time, which can lead to the bend of internal contacts or the breakage of the reader pins.
Another common mistake is using homemade tools of inadequate thickness. A needle too thick can scatter the ejection mechanism, and a needle too thin will just slip past the lever. Also, don't ignore the direction of installation: in Xiaomi, the tray often has only one right side of the entrance, and trying to flip it can damage the frame.
⚠️ Note: If you used glue to fix the tray (which is sometimes done in services), in any case do not heat the phone with a hairdryer to extract it, without understanding the type of glue.
Avoid rushing. If you don't get it the first time, you'd better put your phone down, take a few deep breaths, and try again in good light. Stress and shaking in your hands are the biggest enemies when you're working with small electronics. Accuracy and consistency are more important than speed.
💡
The correct orientation of the tray and the use of a tool of the right diameter is the key to successful recovery without damage.
