Installing the communication module is the first and most important step after unpacking the new Xiaomi Redmi 10 smartphone. Many users face difficulties, as the design of the tray may differ from the usual models of previous years. Mishandling the thin mechanisms of the body can lead to damage to the device, so it is important to clearly understand the sequence of actions.
In this article, we will discuss in detail how to insert a SIM into the Xiaomi Redmi 10 to avoid typical errors. We will look at the features of the hybrid slot, the nuances of extracting the tray without using the original clip and the correct orientation of the chip.
Before you start manipulating, you need to prepare the workplace, you need a flat surface with good lighting, so you don't drop small parts, and also make sure your hands are dry and clean, as fat or moisture can adversely affect the electrical contacts of the board.
Tool preparation and tray inspection
You don't need a sophisticated technical arsenal to get started, and the main tool is a special metal clip that comes with the box, and if the original key is lost or missing, you can use a regular paper clip, straighten it, or a thin needle, but you need to be very careful.
Carefully inspect the side face of the Redmi 10 smartphone. SIM-cards are usually located at the bottom of the device, next to the charging connector USB Type-C. You'll see a small circular hole, and that's where you put the tool to extract the mechanism, and don't confuse that hole with a noise reduction microphone, which is on the opposite end or side, but has a different shape.
It is important to note that the Xiaomi Redmi 10 model uses a combined tray, which means that the second slot can work either as a place for a second SIM card or as a slot for a microSD card. Simultaneous use of two SIMs and a memory card is impossible without the use of special adapters, which are not recommended by the manufacturer.
⚠️ Warning: Never attempt to remove the tray using sharp objects such as a knife or a wide-base pin.You risk damaging the internal machinery or scratching the body of the device.
💡
If the paperclip is not inserted into the hole, try to rotate it slightly around its axis. The hole may be hidden by a protective layer or have a specific angle of entry.
Module extraction and installation process
Once you've decided on the tool, insert it into the tray hole perpendicular to the body. Press it with moderate force until you click the characteristic spring mechanism pushes the tray outwards a few millimeters, after which it can be gently tucked with your nail and removed completely.
Put the extracted tray on the table and look at its structure. It has two notches of different sizes. The larger notch is for a memory card or a second nano-SIM SIM card, and the smaller one is strictly for the main SIM card. Notice the bevelled corner of the chip: it should match perfectly the bevelled angle in the plastic tray.
Put the nano-SIM in the appropriate socket, making sure that the golden contacts are pointing down. The microSD card, if used, is also set downwards. The tray should snap into the case without undue effort. If you feel resistance, check that the cards are aligned correctly.
☑️ Proper installation SIM-map
In some cases, users are faced with a situation where the tray does not push out after pressing.This may mean that you have not entered the tool deeply enough or hit the wall of the mechanism. Try to change the angle of the needle, but do not apply excessive force so as not to break the plastic holder inside the case.
Features of the hybrid slot in Redmi 10
The Xiaomi Redmi 10 design includes a hybrid slot, a common practice in the budget and mid-range smartphone segments, which allows you to keep the device thin while sacrificing the ability to simultaneously install two SIM cards and a memory expansion card.
If it is critical for you to use two SIM cards and a memory card at the same time, there are special adapters, but their use can lead to unstable network operation or even a tray stuck. Xiaomi manufacturer does not guarantee the correct operation of the device when using third-party adapters.
When you install a memory card in the second slot, the system will automatically reconfigure the file system. However, if you decide to replace the memory card with a second SIM card, you will have to reboot the device so that the network re-registers the subscriber. The process of switching between slot modes is software, but physical replacement of the cards requires the tray to be removed.
What happens if you put it in? SIM-wrong-side?
It’s also worth mentioning 4G and 4G+ support. Properly installing a SIM card in the first slot (usually marked with a 1 or closer to the edge of the tray) guarantees top internet speeds if your carrier maintains these standards in your area.
Network settings after installation
After physically installing the cards and turning on the smartphone, the operating system MIUI It's going to automatically identify new modules, and you're going to see the network indicators at the top of the screen, if that doesn't happen, or if you see a message saying, "No." SIM-maps, you will need manual adjustment.
Go to the Settings menu, then select a paragraph. SIM-Maps and mobile networks. Both slots are displayed here. Make sure the switches in front of the cards are activated. If the memory card is not identified, check the formatting: it must be in the format to work with a smartphone. FAT32 exFAT.
You can also set the priority menu. SIM-Call card and mobile Internet, which allows you to manage costs flexibly, assigning a specific number to each contact or application, and this is especially convenient for those who share personal and work communication.
| Parameter | Slot 1 | Slot 2/microSD |
|---|---|---|

| Support for 4G/5G | Yes. | Yes (SIM only) |
| Max, memory capacity. | - | up to 512GB |
| Orientation of contacts | Down. | Down. |
Typical problems and ways to solve them
Even when installed correctly, software failures sometimes occur. SIM-If you try to wipe the chip contacts with a soft wipe or an alcohol wipe, contact oxidation is a common cause of signal loss, especially if the device has been lying idle for a long time.
In the case when the smartphone does not see the memory card, but the SIM card recognizes, the problem may be in the file system of the drive. Android does not support the NTFS format by default. You will need to format the card through the computer or directly in the phone storage settings by selecting the option "Internal memory" or "Portable storage".
Sometimes, after updating the MIUI firmware, the settings of the APN access points are lost. If the Internet is not working, although the 4G indicator is on, go to the mobile network settings and select "APN" Press the reset button to the factory settings or create a new point, the data for which can be found on your carrier's website.
⚠️ Warning: If the phone is heated in the tray area SIM-This may indicate a short circuit or malfunction of the communication module itself.
You can use an engineering menu to diagnose network problems. Enter ##4636## in the Phone app. In the menu that opens, select Phone Information. Here you can see the signal level in dBm, network type, and force the network mode to switch, for example, to LTE Only, if you see constant switching between 3G and 4G.
💡
Most of the problems with definition SIM-cards are solved by simple cleaning of contacts or re-installing the tray.
Security and map extraction
Smartphones including Redmi 10 support hot replacement" SIM-The card, but the manufacturer still recommends turning off the device before removing the tray, this prevents potential data recording errors and voltage surges on the contacts.
To safely extract the card, use the paperclip again. Push the hole before you click and take out the tray. Don't touch the golden contacts with your fingers, because skin fat promotes oxidation. Take the card only by the plastic edges.
If you plan to sell your phone or give it away for repair, remember to delete all data. Resetting to factory settings doesn't always guarantee complete deletion of information from your memory card, so physically extracting the microSD is the most reliable way to keep privacy.
