Why the Right Installation SIM-The cards are important for the Redmi Note 10 Pro

This model supports two nano-SIMs (or one SIM + memory card), but the tray here is combined - you need to handle it carefully.

There are no buttons or connectors nearby, so it is difficult to confuse.

If you hold your phone with your screen, the slot will be on the left, just below the camera (when you look at the back), and some versions of the device have a sign that says "SIM" or a card icon next to the hole, which is an additional landmark.
