How do you put it in? SIM-map in Xiaomi Redmi Note 10S: guide

Installing a carrier card is the first and most important step after unpacking a new smartphone.The Xiaomi Redmi Note 10S model features a hybrid slot, which allows you to use two SIM cards at the same time or one SIM card along with a microSD memory card. Properly installing the chip guarantees a stable signal and no networking problems in the future.

Owners of the device need to be careful when removing the tray, as the mechanism is small and requires careful handling. Incorrect location of contacts can lead to the fact that the phone will not see the network or will only work in 2G mode. In this article, we will discuss in detail the process of installation, setting priorities and solving common technical difficulties.

Before you start physically affecting the body of the gadget, make sure that you have all the necessary tools. Usually a special paper clip is included with the device, but if it is lost, a thin needle or pin will fit, the main thing is to act confidently, but without excessive effort, so as not to damage the extraction mechanism.

Preparation for installation and search for a slot

The first thing you need to do is locate the SIM card tray, which is on the lower end of the Redmi Note 10S, between the Type-C charging connector and the main microphone opening, and the tray is elongated and fits tightly into the device's frame to provide dust protection.

Removal requires a thin metal object. If the original paper clip from the box is lost, you can use a stationery needle, but you should not use thick-eyed sewing needles or knives, as they can easily damage the internal mechanics or scratch the body. Carefully insert the tool into a round hole on the tray frame.

Press the perpendicular surface of the phone on the paper clip, and you feel a slight click, and the tray will push slightly outward, and then you can effortlessly pull it out with your fingers.

💡

If the tray does not extend after pressing the paper clip, try to slightly change the angle of inclination of the tool. Do not make excessive efforts so as not to break the push mechanism inside the case.

Scheme of location and installation of chips

The tray in Xiaomi Redmi Note 10S It has a combined design. It has two seats for SIM-Nano-SIM cards and one place for a microSD card. However, the third slot is common: you can use either a second SIM card or a memory card, but not both elements at once.

Notice the shape of the notch in the tray. The cards should lie strictly in their recesses. Nano-SIM is the smallest format of cards, so the usual or micro-sims will need to be replaced by the carrier or carefully trimmed through a special frame. The contacts on the chip should be directed down to the inside of the tray.

The cut corner of the card must match the notch shape in the plastic holder, if the card lies wrong or protrudes beyond the edges, it is installed incorrectly, and after placing all the necessary elements (one or two SIM cards and possibly flash memory), the tray should be returned to the phone.

When you put the tray back in, you're going to be able to see its orientation. It's going to go in smoothly and point-blank. If you feel resistance, don't push -- it's probably upside down or shifted. It's like the tray is rightly mounted against the body of the phone, and it doesn't protrude outward.

Setup of two SIM cards in MIUI

Once the smartphone is turned on, MIUI will automatically detect the communication modules installed. If two cards are inserted, a notification will appear on the screen about the dual-SIM setting, the user is asked to assign one of the main cards for the mobile Internet, and leave the other for calls or use by default.

To change the settings at any time, open the settings menu and go to the section SIM-Maps and mobile networks. This shows both slots, even if one of the cards is not active, you can switch them, change the names (e.g., "Work" and "Home") and customize the preferred network type for each slot separately.

• 📱 Main card: selected for data transfer 4G/LTE, What is critical for internet speed.
• 📞 Voice calls: You can set a priority SIM card for outgoing calls or leave a choice each time you dial.
• 💬 SMS-Messages: By default, a card with a stronger signal is used, but you can fix a specific number.

It is important to consider that when two SIM cards are activated in 4G mode, the second card can switch to 2G mode during a conversation on the first one, if VoLTE technology is not supported.

Use a memory card instead of a second SIM

Many users are faced with a dilemma: whether you need a second SIM card or more importantly an expansion of internal memory. Redmi Note 10S supports microSD cards up to 1 TB. If you choose this option, the second slot for communication will become unavailable.

To install the memory card, follow the same tray extraction procedure. the microSD is installed in the same slot as the second SIM card, but on the reverse side or depending on the design of the specific revision tray (in this model they are often located on the same plane, but occupy one physical place).

⚠️ Note: Formatting a memory card will delete all the data that was on it. If there are important files on the flash drive, copy them to your computer first.

Once formatted, the map will be available as part of internal storage or as a portable storage, and in the Memory settings, you can transfer photos, music and some applications to an external medium, freeing up space for the system to work.
