Xiaomi smartphones (including Redmi sub-brands and POCO) They support memory expansion with microSD cards, but the slot's location can vary depending on the model. SIM-In some cases, the card requires the tray to be removed with a paper clip, and in some flagships (for example, Xiaomi 13 Pro) the slot is not at all.
If you are first faced with the need to install or remove a memory card, it is important not only to know where exactly the slot is looking, but also how to handle the tray correctly so as not to damage contacts. In this article, detailed diagrams for popular models, tips for choosing a card and warnings about typical errors that lead to breakdowns.
Before you start searching, check if your Xiaomi model supports memory cards. For example, the Redmi Note 12 Pro+ has a hybrid slot (SIM + microSD), and the Xiaomi 12T only has a two-sim tray without the possibility of expansion. This information is usually listed in the device specifications on the official website or in the instructions.
1.How to determine if your Xiaomi has a memory card slot
Not all Xiaomi smartphones have a microSD slot. To avoid wasting your search, check this out first.
- π Official website: Find your model in the "Specifications" section (e.g. mi.com).Look for Memory extension or Storage expansion.
- π Documentation: In the box with the phone should be a brief instruction with a scheme of slots.
- π οΈ Visual inspection: If you see a tray on the side of the phone with a small hole for a paper clip - most likely, it is a hybrid (SIM + microSD or 2 SIM + microSD).
Pay special attention to the flagship models of Xiaomi in recent years, for example, the Xiaomi 13 series and Xiaomi 14 completely abandoned memory card slots in favor of integrated memory UFS 3.1/4.0. The same applies to some devices POCO F5 and Redmi K60.
Example: In the Redmi Note 11 Pro+ 5G slot hybrid β you can install either two nano-SIM, or one SIM + microSD. and Xiaomi 11T Pro slot is missing.
2. Where exactly is the slot for the memory card: schemes for popular models
The location of the slot depends on the design of the phone, and it is 90% on the left or right side, less often on the top end (as in the POCO X3 Pro), and below are the diagrams for the most common lines.
General rule: If there is a slot, then it is always next to the tray for SIM-The following are typical options:
| Xiaomi model | Slot location | Slot type | Max, the volume of microSD |
|---|---|---|---|
| Redmi Note 10/11/12 | Left face (under the lid) | Hybrid (SIM2 + microSD) | 1 TB |
| POCO X3/X4/X5 | Right face (separate tray) | Dedicated (2 SIM + microSD) | 512GB |
| Xiaomi 11 Lite 5G NE | Left face | Hybrid | 1 TB |
| Redmi 9/9A/9C | Right edge (under the removable cover) | Highlighted | 512GB |
| Xiaomi Mi 10T/11T | β | No slot. | β |
In models with a removable back cover (for example, Redmi 9A or POCO M3), the memory card slot can be hidden under the battery, in which case access will require gently tucking the cover with a mediator or plastic card to avoid damaging the latches.

3. Step-by-step instruction: how to remove the tray and install a memory card
If you are convinced that the phone has a slot, follow this instruction. You will need: a paper clip (or a special key from the kit), a microSD card (recommended UHS-I U1/U3 class for recording video in 4K).
Step 1. Turn off the phone (required!) This will prevent the contacts from being damaged when the tray is removed.
Step 2. Find the opening to remove the tray, which is located next to the slot, and insert the unbended clip into it before you click.
Step 3. Pull the tray out carefully. Don't make any effort -- if it doesn't come out, check if the paperclip is fully in.
Step 4: Set the memory card in the appropriate slot (usually signed with a microSD or TF). Pay attention to the direction of the contacts - they should "look" down.
Step 5. Put the tray back before you click. Make sure it sits smoothly, without skewing.
βοΈ Check before installing a memory card
After turning on the phone, the memory card should be determined automatically. If this does not happen, go to Settings β Memory and click Update.

- πΎ Volume: Maximum supported volume depends on the model (see table above). For example, Redmi Note 12 works with cards up to 1 TB, and POCO M4 Pro - up to 512 GB.
- π Brand: Preference is given to trusted manufacturers: SanDisk, Samsung, Kingston, cheap no-name cards are often forged, resulting in data loss.
A critical mistake: using exFAT or NTFS cards in older Xiaomi models (released before 2019), which only support FAT32, and a card larger than 32 GB will not be recognized, so format it into FAT32 on a PC.
To check the speed of the card after installation, use applications such as A1 SD Bench (available on Google Play) Normal metrics for UHS-I U3:
- Reading: β₯ 80 MB/s
- Record: β₯ 30 MB/s
