Owners of Redmi smartphones 9A Often, they need to be replaced. SIM-It's a memory card or a memory card, whether it's switching to a new operator or installing a storage device. Despite the simplicity of modern gadgets, it's not always immediately clear where the tray extraction hole is and how to proceed so that the case is not damaged. Proper extraction is the first step to safely working with the internal components of a device.
Xiaomi Redmi 9A has a classic layout, where the slot is combined with a place for microSD. In this article, we will discuss in detail the extraction process, consider the necessary tools and answer frequent questions that arise from users. It is important to be careful, since inept actions can lead to failure of the mechanism.
Before you start taking action, you should understand that you are working with an electronic device, although the risk is minimal, it is better to be safe and follow proven algorithms. Below are detailed steps to help you easily get a SIM card.
Location of the tray for SIM-map
The first thing you need to do is find the tray itself. In the Redmi 9A, like most modern Xiaomi models, the SIM card slot is located on the top end of the case. It's a standard place that allows manufacturers to maintain the tightness and aesthetic appearance of the rear panel. If you swipe your finger on the top edge, you will notice a small oblong hole next to the circular micro-hole.
It's important not to confuse the tray extraction hole with the noise reduction microphone hole. SIM-The map is elongated and on one side, whereas the microphone is a tiny dot, often centered or nearer to the edge, but without the plastic or metal frame of the tray around it.
Some users mistakenly look for a slot on the side of the box where the volume buttons are located. In the 9A model on the right, there are only the control keys. The tray is always strictly on top. If you can't find it visually, use a flashlight to better illuminate the end of the device.
💡
Use the bright light or flashlight of another phone to better view the upper end of the smartphone – this will help to accurately determine the location of the tray and not confuse it with the microphone.
Once you're sure of the location, you can move on to tool preparation. Don't try to open the tray with your nails or sharp objects like a knife, as this can damage the body or the latch mechanism itself.
Required tools for extraction
To do this, you'll need a special key that comes with your phone, usually a small metal clip or a plastic tool, and if the original key is lost, you can replace it with a regular paper clip, straightening one of the ends of it, and the main requirement is that the tool should be thin and durable enough.
Do not use needles, pins or sharpened objects to remove the tray. Sharp ends can slip and scratch the body, and damage the latch mechanism inside the hole. In addition, a too thin needle can simply bend, getting stuck inside.
- 🔑 Original key-clip from the delivery kit.
- 📎 Regular paper clip (straightened).
- 💡 Lighting for better lighting of the workplace.
- 🧻 Dry soft fabric for wiping contacts (if necessary).
If you don't have a key or a paper clip on hand, you can use a thin sting from a flat-slide screwdriver, but only if it is perfectly thick to match the hole.
☑️ Preparation for extraction SIM-map
Step-by-step instructions: how to get a tray
The process of removing the tray takes only a few seconds, but requires precision. First, make sure that the phone is lying on a stable surface with the screen down or is held firmly in one hand. The screen down is safer to place so that when the tool slides, the display does not scratch.
Insert the prepared tool (clip or key) into a circular hole next to the tray. The movement should be strictly perpendicular to the edge of the body. You do not need to push with all your strength; a fairly confident but moderate press. You should feel a slight click or spring resistance.
⚠️ Warning: Do not tilt the tool at an angle when pressed.This can lead to deformation of the hole or breakage of the internal mechanism of the pusher.
Once the tray is slightly out (literally 1-2 millimeters), put the tool away and gently pull the tray with your fingers. Don't pull sharply. If the tray is not taken out easily, then you haven't pressed the key deeply enough or hit the wrong mechanism. In the Redmi 9A, the tray is combined, so it can sit tight.
What to do if the tray is stuck?
After removing the tray, place it on the table face up. Notice the marking that will tell you which slot to install. SIM-The card and which memory card are usually the main SIM, and the slot 2 is the second SIM or microSD.
Features of the combined slot
Unlike older models where slots were split, Xiaomi Redmi 9A It uses a hybrid tray, which means that physically spaces for two. SIM-The cards and memory cards are limited in design. SIM-card SIM and one microSD card.
The design of the tray has special cutouts and limiters. SIM-The card should be in its recess in a strictly shaped way. SIM Or vice versa, they just won't get in place. Orientation of contacts is also key.
| Configuration | Slot 1 | Slot 2 | The result |
|---|---|---|---|
| Two. SIM | Nano-SIM | Nano-SIM | Both networks work. |
| SIM + Memory Card | Nano-SIM | microSD | One network + expansion of memory |
| Only a memory card. | Empty. | microSD | Just the drive. |
| Wrong installation | MicroSD in SIM | - | Won't stand/Mistake |
This is the smallest standard at the moment. If your SIM card is larger, it needs to be replaced from the operator or carefully cut out according to the template, although the latter option is risky due to possible damage to the chip.
💡
The hybrid slot allows you to choose between a second SIM card and additional storage, but using all three elements at the same time is impossible without cloud services.
Safe extraction and installation of the card
When you have the tray in your hands, take it out. SIM-Try not to touch the golden contacts with your fingers, as fat pollution can oxidize over time and worsen the connection. If the microSD card is installed in the next slot, it is also easily removed.
When you reverse-mount, make sure that the bevelled corner of the card matches the circuitry on the tray. The card should lie flat, without protruding beyond the edges. If you insert a microSD, it should click or lock in the plane of the tray. In some designs of Xiaomi trays, the memory card is inserted on the back of the tray or into a special slot on the top.
- 📱 Make sure your phone is turned off before installing a new card.
- 🧹 Wash contacts with dry cloth if they are contaminated.
- 🔍 Make sure the card doesn’t stagger in the tray after installation.
- 🔄 Insert the tray into the phone only in the correct position (usually the bevelled corner is oriented in a certain way).
Putting the tray back in the case, watch the direction. It should go in smoothly. If you feel resistance, don't push. Take out the tray, turn it over and try again. Forced indentation can break the contacts inside the phone.
⚠️ Warning: Never insert a tray unless it is installed or SIM-card, or memory card, if your specific region's design involves a plastic plug, and working without a plug can cause dust to enter the case.
Frequent problems and their solution
Sometimes, after installing the card, the phone may not see the network or issue a message "SIM-This may be due to improper installation, contamination of contacts or software failure. First try to reboot the device.
If the problem persists, remove the tray again and check the position of the card. Make sure it is not skewed. Also, wipe the contacts with a wipe or an alcohol wipe. In rare cases, the tray itself can be deformed, which prevents the card from attaching tightly to the contacts.
If you are using a large memory card (such as a 128GB or 256GB), make sure the file system is formatted correctly (usually exFAT or FAT32).The Redmi 9A may not read cards with an NTFS file system without third-party software.
In case the tray fell out on its own or dangled, the fixing "tissues" on the tray itself may have worn out, and they can be gently bent outwards slightly with a thin tool to increase the pressure on the map and ensure reliable contact.
