The tray is a combined mechanism that allows the use of either two. SIM-card SIM-card and one memory card, depending on the modification, but in the global version, the most common option is two Nano-SIM without support for microSD memory cards.
If you look closely at the tray, you'll notice that it has two notches on different sides, one side is for the main card, the other side is for the extra card. It's important not to confuse them, although they may look physically similar, the phone's software may react differently to placing cards in different slots when you first start.
It is worth noting that in some revisions, the tray can be colored in the body color or have a rubber seal to protect against moisture and dust according to the IP53 standard.
Step-by-step instructions for removing the tray

Proper orientation and installation SIM-map
The most critical point is the correct orientation of the chip. On the tray Xiaomi Mi 10 usually has a schematic image showing how the card should lie. Golden contacts should always be directed downwards, to the inside of the tray, and the cut corner of the card should match the shape of the notch in the plastic.
If you are setting two cards, make sure they are not superimposed on each other and sit tightly in their niches.The cards must lie level with the edges of the tray without standing up, otherwise when closing the tray, you can damage the contacts or the card itself.
⚠️ Attention: Don't insert SIM-This can lead to short circuit or mechanical damage to the reader inside the smartphone.
To install one card in the second slot (if the first one is occupied or vice versa), just leave the free space empty. The MIUI system automatically detects the presence of only one module. If you use cards from different operators, it is more convenient to put the main one (for calls) in slot 1.

Comparison of slot characteristics and support of networks
Users are often wondering if there is a difference between the first and second slots. In the Xiaomi Mi 10, both slots support modern communication standards, but there are nuances in working with fifth-generation networks. Below is a table showing the main differences and capabilities.
| Parameter | Slot 1 | Slot 2 | General opportunities |
|---|---|---|---|
| Map format | Nano-SIM | Nano-SIM | Only Nano. |
| Support for 5G support | Yes (main) | Yeah (on switching) | SA/NSA regimes |
| 4G LTE | Support | Support | Frequency aggregation |
| Mode of work | Active. | Active (Dual 4G) | One active 5G |
Dual 4G technology allows both SIM cards to be on the 4G network simultaneously, waiting for an incoming call. However, if one card goes into 2G or 3G talk mode (depending on the operator), the second card may temporarily lose high-speed access.
It is important to know that 5G on both SIM cards requires support from the operator and the corresponding setting in the menu, since the radio module can physically process only one 5G data stream at a particular time.
