Modern Xiaomi smartphones are famous for their thoughtful design and functionality, but new owners often have difficulties with initial setup, in particular, with the installation of a communication module. 11T It's no exception: its ergonomic body and the lack of physical buttons on some faces can be confusing for the first time the person who took the device in his hands. SIM-The card is a critically important stage, since it depends on the stability of the mobile network, Internet speed and the ability to use two numbers at the same time.
In this guide, we will go through all the details of working with the card tray to eliminate the risk of damage to the device. Incorrect actions can lead to failure of the extraction mechanism or damage to the contacts of the card itself, which will entail additional costs.
Before you start the process, make sure you have the original tray extraction key or its quality counterpart on hand.The use of sharp objects such as needles or pins is not recommended, as they can slip and scratch the case or, worse, damage the micro-mechanism inside the hole.The safety of your actions is the number one priority when working with sleep electronics.
Preparation of the workplace and necessary tools
The first step is to create a comfortable space for work, and you need a flat, well-lit surface, preferably a soft surface, such as a table with a cloth or a mouse mat, in case you accidentally drop it. SIM-map or tray: soft surface will prevent them from slipping and losing in hard-to-reach places.
The main tool is a special key-clip, which comes with the Xiaomi 11T. It has a specific shape, ideal for a calibrated hole in the case of the smartphone. If the original key is lost, you can use a standard paper clip, first straightening one of its ends, but you need to act with extreme care not to expand the hole.

- 🔑 Original key for tray extraction or quality replacement.
- 💳 Active. SIM-Nano-SIM card from your carrier.
- 💡 Good lighting for accurate hitting the hole.
It is also recommended to prepare the operator card in advance.Make sure it matches the Nano-SIM format, as older formats (Mini or Micro) will not physically fit into the tray or may get stuck.If your larger card is available, contact the communications salon to replace it or carefully trim it around the circuit using a special stencil, although the latter option is less reliable.
⚠️ Warning: Never try to insert a tray into a phone until it is fully removed.Pushing the tray back to the end without first removing it can cause permanent damage to the motherboard's internal contacts.
Location of the tray and the extraction mechanism
In the Xiaomi model 11T Engineers have placed a tray for SIM-cards on the lower edge of the device, near the charging port USB Type-C and speaker: This is the standard location for most modern smartphones, providing easy access. The tray is a thin metal frame with a plastic insert that fits tightly to the body, protecting the internal components from dust.
To remove the tray, find a small circular hole at the end of the frame. Put the key perpendicular to the surface of the case. It is important to keep the key strictly at a right angle (90 degrees) so as not to bend it and damage the mechanism inside. Sloping the key to the side can cause it to slip and scratch the aluminum frame of the phone.
You have to make a steady but steady effort, and you have to feel a little click, and you see the tray extend a few millimeters, and then you can gently tuck it with your nail or the edge of the key and remove it completely. Don't use excessive force: if the tray doesn't come out, check the angle of the key is correct.
Particular attention should be paid to the design of the tray in Xiaomi 11T. Unlike some other models, it uses a combined or double tray that can support two physical trays. SIM-On the inside of the tray, you'll see special notches that repeat the contours of the maps, and the orientation of the maps should strictly correspond to the image on the tray itself or on the body of the smartphone.
Algorithm of SIM-card installation in Xiaomi 11T
The installation process requires care and precision. Put the extracted tray on the prepared surface with the notches up. Take your Nano-SIM card and carefully examine it: one of the corners of the map is cut. This cut angle should coincide with the same protrusion in the tray lobe.
☑️ Installation checklist
Carefully place the card in the appropriate cell. It should lie flat, not protruding from the edges of the tray and not staggering. If the card is not tight or rises above the surface of the tray, then it is installed incorrectly or is incorrectly sized. In this case, do not try to insert the design into the phone, as this can lead to a spell.
Once you've successfully placed the card, take the tray by the edges and enter it into the hole on the phone body. The tray should enter smoothly, without resistance. Bring it to the end with a light finger press to the characteristic click. The outer surface of the tray should be level with the smartphone body, forming a single plane.

If you use two of them SIM-Repeat the procedure for the second tray cell, make sure both cards are securely fixed. 11T There is no support for microSD cards, so the entire tray is occupied with SIM card slots, making their proper installation even more important for the functionality of the device.
Network setup and connection check
After you physically install the cards, turn on your smartphone. MIUI automatically detect new SIM-The map will show a notification of the networks found, and the phone may suggest that you adjust the Internet settings, which is usually automatic, but in some cases, manual intervention is required.
To check the status of the connection, go to the settings menu. Open the Settings section. → SIM-You'll see a list of maps installed here, if the map is correctly identified, the operator and signal strength will be next to it, if it shows "No service" or "Not known", check if the map is installed correctly.
