Have you just bought a Xiaomi Redmi 10 and want to expand memory with a microSD card but can't find a slot? Or have already inserted a drive but the phone doesn't see it? This problem is familiar to many owners of Xiaomi budget smartphones, where the design of the case often hides obvious solutions. Unlike flagship models, where the memory card slot is put on the side edge, in Redmi 10 it is hidden under the cover - and that's only half the story.
In this article, we will not only show the exact location of the microSD slot in your model, but also analyze the nuances of its opening (including tools that you will need), compatibility with cards of different standards (SDHC, SDXC), as well as typical errors that may not allow the phone to recognize the drive.
Where exactly is the memory card slot in Redmi 10

What does that mean? There are three positions in the tray.
- First first SIM-map (nano-SIM)
- Second second SIM-microSD card or memory card (choice)
- The third position is missing – it is empty space for easy extraction.
It's important. You can't use two at the same time. SIM-I'll have to choose between two cards and a memory card. SIM, one SIM + MicroSD. This is a limitation of Xiaomi's budget model architecture.
How to open a tray for a memory card: step-by-step instructions
To get to the microSD slot, you'll need a paper clip or a special key (complete with your phone) if you don't have a key, any thin metal wire or even an unbended stationery clip will do.
Turn off your phone (recommended, but not required)
Find a hole to extract the tray on the left side
Insert the paperclip into the hole before clicking.
Pull the tray over yourself with a smooth movement-->
Then proceed with the algorithm:
- Find the hole on the left side of the case (near the volume buttons) that's barely visible, but if you look closely, you can see a metal ring inside.
- Insert the paperclip into the hole at an angle of 45 ° and slightly press until the tray “pop out” by 1-2 mm.
- Remove the tray with your fingers. Don't pull too hard, it's fixed by a spring mechanism.
- Place the microSD in the appropriate slot (usually signed SD or microSDXC). Contact down!
- Put the tray back in before you click. Make sure it sits flat or the phone won't recognize the card.
In the 2022 Redmi 10, the tray has a small ledge-cut angle - this is a clue as to how to insert it correctly (the ledge should be on top). In earlier versions (2021), there is no such ledge, so focus on the inscriptions on the tray itself.
