Why installing a SIM card in Xiaomi is important
A SIM card is not just a plastic chip, but a key to mobile connectivity, the internet, and even some of your Xiaomiโs security features. Installation can lead to network failure, damage to contacts, or even slot breakdown, especially for modern Redmi, POCO, and Xiaomiโs flagship 13/14 series, where slots are becoming more compact and fragile.
In this article, we will discuss not only the basic installation procedure, but also nuances that are not written in the official instructions, such as why some SIM cards are not defined in dual-sim phones, how to avoid tray jamming, and what to do if the slot is jammed, and you will learn how the procedures differ for models with a hybrid slot (where the second slot is combined with a memory card) and for devices with eSIM.
If you're first encountering the Xiaomi brand or switching from the iPhone/Samsung, note that there are some features here. For example, in most Xiaomi smartphones, the SIM card tray is pushed only with a clip - you can't pull it out with a finger, unlike some competitors. And in the POCO F5 or Redmi Note 12 models, the slot is not on the side, but on the top, which can be confusing.
What SIM cards are suitable for Xiaomi: nano-SIM, eSIM and adapters
Most of the modern Xiaomi smartphones (released after the 2018 Only nano-SIM is supported, the smallest SIM format 12.3 ร 8.8 If you have an old micro-SIM or mini-SIM, you'll have to trim it or replace it in the cabin of the operator. โ Nano-SIMs are not recommended โ they can get stuck in the slot or damage contacts.
Some flagship models (Xiaomi 13 Ultra, Xiaomi 14 Pro) also support eSIM, a virtual SIM card that can be activated without a physical chip. However, in Russia, this feature is not yet available for all operators.

Where is the SIM card slot in Xiaomi: location by model
Depending on the Xiaomi model, the SIM card slot can be in three places:
- On the right is the most common location (e.g. Redmi Note 10, POCO X3).
- The top is typical of some POCO models (e.g. POCO F5) and older flagships (Xiaomi Mi 9).
- On the left, it is rare, but it is found in separate series (for example, Xiaomi Mi Mix).
To determine exactly where the slot is in your model, look around the phone body. Look for a small hole (about 1 mm in diameter) is a jack for the clip-extractor. If you are not sure, use the official guide or watch a video review of your model on YouTube.
How to find a slot if you can not see it?
If you canโt find the slot, check out:
- ๐ Phone box โ there may be a scheme with the location of the slot.
- ๐ Xiaomi official website โ in the โSpecificationsโ section of your model.
- ๐ฅ Video disassembly - on YouTube there are videos for disassembling almost all models.
โ ๏ธ Note: In some Xiaomi models (such as the Black Shark), the SIM card slot can be hidden under a removable back cover. Do not try to open it without special tools - this can damage the case or detach the glue.
Step-by-step: how to insert a SIM card in Xiaomi
Now, to the most important thing, install the SIM card directly, follow this instruction to avoid errors.
- Turn off the phone.This is not necessary, but it is recommended to avoid accidental damage to the contacts during installation.Push and hold the power button, then select Turn off.
- Find a clip that's extractive. It comes with a paper clip that comes with the phone, which is also called the SIM card key, and if it's not there, you can use an unbended paper clip or needle, and don't use pins or toothpicks, because they can break inside the slot.
- Put the paper clip into the slot hole. Press until you click a little. The tray should extend 2-3 mm, now it can be pulled out with your fingers. Don't use excessive force: if the tray is not extended, check if you pressed the right hole (sometimes there is a microphone hole nearby).
- Put the SIM card in the tray. Notice the position of the chip -- there's usually a diagram on the tray where to insert which end of the SIM card. For dual-SIM phones, the top slot usually corresponds to SIM 1 (main SIM card).
- Put the tray back in. Slowly push it up to click. Make sure it sits straight -- if the tray is skewed, the SIM card may not be in contact.
- Turn on your phone and check the network. Wait for the network indicator to appear after you turn on (usually in the upper right corner). If there is no network, restart the phone or check if the SIM card is installed correctly.
โ๏ธ Check before installing the SIM card
If after installation the SIM card is not determined:
- ๐ Reboot the phone.
- ๐ถ Check the coverage area โ it may not be the phone that is the problem, but the operator.
- ๐ ๏ธ Clean the SIM card contacts with a soft cloth (do not use alcohol or liquids!).
- ๐ง Try another slot (if the phone is two-sim phone).
๐ก
If the tray is stuck and doesn't extend, don't try to pull it out by force. Put the phone on a flat surface, press the tray slightly on the side, and try to press the paperclip again. If it doesn't work, contact the service center.
Frequent errors when installing a SIM card and how to avoid them
Even in a simple procedure like installing a SIM card, users often make mistakes, and here are the most common ones and ways to solve them:
| Mistake. | Reason. | Decision |
|---|---|---|
| SIM card not defined | Misplaced Chip Position, Dirty Contacts | Reinstall the SIM card, clear the contacts |
| The tray is not moving out. | The hole clogged, the paperclip too thin. | Use the original paper clip or contact the service |
| Phone does not see second SIM card | Hybrid slot is occupied by memory card | Select priority: either two SIM cards or one + microSD |
| SIM card stuck in slot | Used an adapter or SIM card of the wrong size | Donโt try to pull it out yourself โ contact the service |
One of the most frustrating things is when a SIM card tray gets stuck inside a phone, which can happen if:
- ๐ง You used a non-original paper clip (such as a needle or toothpick) that broke inside.
- ๐ The SIM card was the wrong size (e.g., a micro-SIM without an adapter).
- ๐ฅ The tray was skewed during installation due to excessive effort.
If the tray is stuck:
- Donโt try to pull it out with tweezers or pliers โ this can damage your contacts.
- Try to gently press the tray from the side, simultaneously pressing the paperclip.
- If it doesn't work, don't take risks, go to Xiaomi's service center, and if you try it yourself, you can damage the motherboard.
โ ๏ธ Note: If after retrieving the SIM card you notice that the contacts on the tray or SIM card are scratched or bent, do not use this SIM card further.
Features of installing a SIM card in popular Xiaomi models
