Have you bought a new Xiaomi smartphone, but can't find where the memory card is inserted? Or have already installed a microSD, but the phone does not see it?

In this article, we will analyze all possible locations of the slot in different models (from Redmi Note to POCO F), show how to insert the card correctly, and explain where to look for it in the MIUI settings.

It’s important to understand that Xiaomi has two types of smartphones – a hybrid slot (memory card or second SIM) and a separate slot for microSD. For example, in the Redmi Note 12 Pro+ you can use both SIM and memory card at the same time, and in the POCO X5 you have to choose, we will help determine the type of your device and avoid errors during installation.

3. Insert the paperclip into the hole and press slightly until the tray is pushed out.

If you can’t find the slot, use our tip:

• 📏 Left end: Redmi Note 10/11/12, POCO X3/X4/X5, Xiaomi 12 Lite.
