How to insert a SIM card into a Xiaomi phone: instructions for all models

Installing a SIM card in a Xiaomi smartphone seems like a simple procedure, but in practice, users face problems from the wrong size of the nano-SIM to a jammed tray. In this article, we will analyze all possible scenarios from preparing a map to solving emergency situations. Particular attention will be paid to models with hybrid slots (where you have to choose between the second SIM and memory card), as well as nuances for flagships Xiaomi 13/14 and budget Redmi Note.

You will learn how to avoid damaging SIM card contacts when installed incorrectly (this is a common reason for lack of network), what tools to use instead of a standard clip, and what to do if the tray does not extend after pressing, POCO Redmi released after 2018.

Types of SIM cards and slots in Xiaomi phones

Xiaomi’s current smartphones support three SIM formats: nano-SIM (the most common), eSIM (in flagships since Xiaomi 12), and micro-SIM (older models until 2016). Importantly, if your old-style SIM (mini-SIM or micro-SIM), it can’t just be trimmed to a nano-format, which will damage the chip.

By type of slots, Xiaomi devices are divided into:

• 📱 Single slots – only one nano-SIM (rarely, for example, in Xiaomi Mi). A3).
• 🔄 Double Slots – Two nano-SIMs at the same time (most Redmi Note models) 10/11/12).
• 💾 Hybrid slots – the second slot is combined with a microSD connector (for example, POCO X3 Pro or Redmi 9A). Here you will have to choose: the second SIM or memory card.

To specify the type of slot for your model can be on the official website of Xiaomi in the section “Facts” or in the documentation for the device. For example, the flagship Xiaomi 13 Ultra and Xiaomi 14 support two nano-SIM + eSIM, and the budget Redmi 10C – only hybrid slot.

Preparation: what you will need to install a SIM card

Before inserting the SIM, prepare:

• 📲 Xiaomi smartphone with power off (required!).
• 🪨 The tray extraction tool -- usually comes with a phone (thin metal clip) if you're missing, you'll find a straight paper clip or a needle from a sewing machine.
• 📱 Nano-SIM of the right operator (check if it is activated).
• 🔦 Lantern - will help to consider the slot in a dark room.

Attention! Never use sharp objects (knives, forks, scissors) to remove the tray, which can damage the fixing mechanism or the SIM card contacts. If the clip does not enter the hole, check if it is clogged with dust - carefully clean with a toothpick.

For eSIM-enabled models (e.g., Xiaomi 13 Pro or POCO F5), a physical SIM card may not be required, in which case activation occurs via the Settings menu → SIM cards and mobile networks → Add a mobile tariff. However, most users still need a physical nano-SIM.

Step-by-step: how to insert a SIM card in Xiaomi

Follow this algorithm to avoid errors:

1. Turn off your phone. This will prevent damage to the SIM card contacts during installation. Wait for the screen to shut down completely.
2. Find a SIM card slot. It's usually located on the top or side of the phone (e.g., Redmi Note 11 on the right, Xiaomi 12T on the top). On some models (e.g., POCO F3), the slot is hidden under the lid, you need to remove it.
3. Remove the tray: Insert the paperclip into a small hole next to the slot. Push until you click, the tray will extend 1-2 mm. Gently pull it with your fingers.

Set up a SIM card.

• Put the nano-SIM in the tray chip down, combining the bevelled corner of the card with the tray angle.
• For hybrid slots: if you use two SIMs, the second is installed on top of the first (see the diagram in the documentation).
• Put the tray back in before you click. Make sure it sits smoothly, without skewing.
• Turn on your phone and wait for the network to appear (it can take up to 2 minutes).

If the phone doesn't turn on, check:

• 🔄 SIM card installation (chip must touch contacts).
• 📶 Network settings in Settings → SIM-maps and mobile networks → [your sim] → Network type (recommended) 4G/5G).
• 🔋 Reset the device.

Features for different Xiaomi models

Some Xiaomi devices have unique nuances when installing SIM cards. Consider the most popular series:

For removable lid models (e.g. Redmi 9C or POCO C31), the process is different:

1. Turn off the phone and remove the back cover (start at the corners using a plastic shoulder blade or nail).
2. Remove the battery (if it is removable).
3. Install the SIM card in the slot on the motherboard (usually marked with the inscription SIM1/SIM2).
4. Put the phone back together.

💡

If you have a model with a removable lid, take a picture of the disassembly process - this will help to properly assemble the phone back and not lose small details (for example, sealing rubber bands).

Frequent Mistakes and How to Avoid Them

Even experienced users sometimes make mistakes when installing a SIM card, and here are the most common:

⚠️ Attention! If the SIM card is inserted upwards, the phone won't recognize it, and repeated attempts to install it can damage the contacts. Always check the position of the chip before inserting it.

Mistake 1: Phone can't see SIM card

• 🔍 Reason: SIM is not installed to the end or skewed.
• 🛠 Solution: Remove the tray and make sure the card fits tightly with the contacts. If necessary, bend the contacts in the slot carefully with a thin screwdriver (for experienced users only!).

Error 2: The tray is not fixed

• 🔍 Cause: dust ingress or deformation of the mechanism.
• 🛠 Solution: Clean the slot with compressed air (a canister) or a soft brush. If the mechanism is broken, you need to replace the slot in the service.

Error 3: The phone asks PUK-code

• 🔍 Reason: Three times injected infidel PIN-code.
• 🛠 Decision: PUK-the code is indicated on the plastic carrier of the SIM card or can be obtained from the operator (a call from another phone or through a personal account).

Error 4: No network after installation

• 🔍 Causes: inactive SIM card, operator problems, incorrect settings APN.
• 🛠 Solution: Check the status of the SIM card with the operator. Reset the phone. Update the settings. APN In Settings → SIM-map → [your sim] → Access points (APN) (It is usually enough to choose an automatic setting).

💡

If after all the manipulations, the network does not appear, try inserting the SIM card into another phone. If the problem persists, contact the operator for a replacement card.

How to Remove a SIM Card from Xiaomi if the Tray is jammed

When you push the tray, it's more common than you think, and it can be from moisture to mechanical damage.

Method 1: Alternative tools

• 🔧 Use a thin needle (from a syringe or sewing machine) - it is thinner than a paper clip and can pass into a clogged hole.
• 🧲 Apply a magnet to the slot area – sometimes it helps to shift the mechanism.
• Update your phone software. Sometimes problems with reading SIM cards are solved by updating your firmware (check Settings → About Phone → System Update).

If the SIM card is physically damaged (cracks, chip chip chips), it must be replaced. Operators usually do it for free for 5-10 minutes. For Xiaomi with eSIM support (for example, Xiaomi 13 Pro), you can consider switching to a virtual SIM card – this will eliminate problems with physical media.

💡

If you change your SIM cards frequently (like when traveling), use a retractable nano-SIM adapter that protects the chip from damage when you retract it frequently.
