Where in Xiaomi Redmi 9 slot for memory card: detailed instructions with photo

Why you need a memory card in Redmi 9

Xiaomi Redmi 9 is a popular model with a balance of price and capabilities, but its internal memory (32/64 GB) often ends when used actively. The microSD card solves this problem by allowing you to store photos, videos and applications without cleaning the internal drive. However, many users are faced with the question: where to insert a memory card in Redmi 9 if the slot is not visible from the outside?

Unlike the flagship models, where the tray for SIM-cards is pushed by a needle, in Redmi 9 uses a hybrid slot — it combines space for nano-SIM and microSD. This means that you have to choose: either two SIM-cards or one SIM + memory card. Next, we will analyze where the slot is located, how to open it and what nuances it is important to consider so as not to damage the phone.

Where is the memory card slot in Redmi 9: photo and location

In the Xiaomi Redmi 9 (M2004J19C, M2004J19G) the memory card slot is located on the left end of the case, next to the volume buttons, hidden under a small plastic cover that opens with a special key (included) or a paper clip. It is important not to confuse it with a charging connector on the bottom edge!

The outside of the tray looks like a narrow slot with a small hole to extract, and the photo below shows its exact location:

• 📍 Left side end - between the volume buttons and the upper edge.
• 🔍 Removal hole - diameter ~1mm, closer to the top edge of the phone.
• 📏 Slot size – suitable for nano-SIM (2 units) or 1 nano-SIM + 1 microSD (up to 512 GB).

If you can’t find the slot, check to see if it’s covered with a protective film (on new phones), and make sure to keep the phone facing to yourself – sometimes users confuse the sides and look for a slot on the right end where there isn’t one.

Step-by-step: how to insert a memory card in Redmi 9

The process of installing a microSD in Redmi 9 requires care. Follow the instructions to avoid damage to contacts or getting stuck in the tray:

1. Turn off your phone (optional, but recommended for safety).
2. Take the key to remove the tray (comes with it) or untighten the clip. Put it in the hole on the slot before you click.
3. The tray will extend a few millimeters, pull it out with your fingers carefully, and don't pull the key or the paper clip so as not to break the mechanism!
4. Place the tray on a flat surface. Pay attention to the slots for the SIM-microSD cards: 📱 Upper groove - for nano-SIM 1 (main) SIM). 📱 Medium slot – for nano-SIM 2 or microSD (choose one!). 📱 Lower groove - microSD only (if one is used) SIM).

Put the memory card down with the gold contacts, aligning the bevelled corner with the groove. Press until you click.

Put the tray back into the slot to the point. Make sure it sits flat, and the skews can cause it to break.

When you turn on your phone, you will notice a new memory card. Go to Settings → Memory to format it (if required) or configure it as internal storage.

Turn off the phone (recommended)

Prepare the key or the paper clip

Check the damage map.

Configuration: 1 SIM + microSD or 2 SIM

Which memory card to choose for Redmi 9: compatibility and recommendations

Not all microSD cards work equally well with Redmi 9. The phone supports cards up to 512GB, but there are nuances with speed and reliability.

Note: If you plan to use the card as internal memory (for installing applications), choose models with high read/write speeds (for example, SanDisk Extreme or Samsung EVO Plus).

⚠️ Note: When buying a memory card, check it for authenticity with utilities like H2testw (Windows or F3 (Linux/Mac). Fake cards often have an understated real capacity and fail after a few months.

Frequent errors when installing a memory card and how to avoid them

Even experienced users sometimes make mistakes when working with the microSD slot in Redmi 9.

• 🔌 Phone can't see memory card: Reasons: improper formatting, damaged contacts, incompatible file system. Solution: format the card in exFAT via phone or PC.
• 📵 The tray is not inserted until the end: Causes: skewed SIM-card or microSD, dirt in the slot. Solution: blow the slot with compressed air and check if the cards are installed correctly.
• 🔄 The card is detected but it's permanently disabled: Causes: poor contact, wear and tear of the connector, card defect. Solution: try another card or contact the service center.

If the card is installed, check if it is used as internal memory for applications, in which case the speed depends on the class of the card - U1 may not cope with the load.

How to Use a Memory Card as an Internal Memory

One of the key benefits of Redmi 9 is the ability to use microSD as internal storage, which allows you to install applications directly on the map, saving space in the built-in drive.

1. Insert the card into your phone and wait for notification of the new device.
2. Go to Settings → Memory → [Map Name] → Three Dots (menu) → Storage Settings.
3. Select Internal Memory and follow the instructions. Attention: the card will be formatted and cannot be used in other devices without losing data!
4. After formatting, move the applications to the map in Settings → Annexes → [Select an application] → Memory. → Change.

Note that not all apps can be ported to a card – some (like WhatsApp or banking programs) require internal memory, and the speed of applications from the card will be lower than from the built-in drive.

💡

Before formatting the card as internal memory, back up your important data, which you can't read on a PC or other phone without full formatting.

Alternatives to memory cards: cloud storage and OTG-accumulator

If the microSD slot is second to second SIM-card or you don’t want to sacrifice speed, consider alternative ways to expand memory:

• ☁️ Cloud storage: Google Drive, Yandex Drive or Mi Cloud (from Xiaomi) allow you to automatically back up photos and files.
• 🔌 OTG-flash-drive: USB-Type-C connector drives (or adapters) connect directly to the phone, and you can use flash drives up to 1TB, but they're bulky.
• 📱 Wireless drives: Devices like SanDisk Connect create their own Wi-Fi network to access files. Travel-friendly.

💡

MicroSD is the easiest and cheapest solution for expanding the Redmi 9 memory, but if you need two, it’s a good idea. SIM-maps, consider alternatives like OTG-storage or cloud services.
