Modern flagship smartphones like the Xiaomi Mi 11 require careful handling when initially configured, especially when it comes to hardware. Many users switching from devices with separate memory card slots may have difficulty trying to install a communication module. It is important to understand that the design of the tray in this model has its own features, ignoring which can damage the contacts or the case itself.
In this article, we will discuss the process of installing nano-SIM and eSIM, as well as the issues of network configuration after turning on. The accuracy of actions during the tray extraction stage is critical, since the locking mechanism in premium devices is often performed with minimal gaps. Following the instructions will help to avoid the typical mistakes that beginners make when unpacking the gadget for the first time.
Before you start a physical installation, make sure the device is turned off or at least the screen is locked to avoid accidental pressing or short circuit contacts, although modern power controllers protect against this.
Preparation of the workplace and tools
To successfully install the communication module, you will need a minimal set of tools, which usually comes with the device. The main tool is a special metal clip (removal key) that is shaped like a drop or needle. If the original key is lost, you can use a regular stationery clip, straightening one of the ends of it, but you need to do this carefully so as not to scratch the case.
The work surface should be flat, clean and well-lit, so that an accidentally dropped nano-SIM card does not roll into a hard-to-reach place, since its size is extremely small, and it is also recommended to wipe your hands or use antistatic gloves to avoid leaving greasy marks on the golden contacts of the tray, which can worsen the quality of the connection to the network.
Make sure you have yourself on hand. SIM-The Xiaomi Mi 11 requires a Nano-SIM card. If your card is larger (Micro or Mini), either carefully cut the chip along the contour (which is risky), or contact the operator's salon for a free replacement with the correct format.
⚠️ Warning: Never use sharp objects such as needles or pins larger than the diameter of the hole to remove the tray. Too thick a tool can damage the internal mechanism of the hold, and the tray will no longer be removed.
Definition of the tray type and its location
In the Xiaomi Mi model 11 Engineers have a combined approach to slots. SIM-card is located on the lower end of the device, to the left of the charging port USB Type-C. Structurally, it is a single platform that accommodates two physical nanos.-SIM cards, but does not support microSD cards.
One of the important features is that there is no separate memory card slot, which means that all data, including photos and apps, will be stored in the device’s internal memory. So when choosing a tray configuration, you don’t have to choose between a second SIM card and a flash drive – only two SIM slots are used.
You can see small notches and bevels on the tray that match the shape of the card, usually one of the slots is marked with a small marking or is simply the main one for installing the first card. It is important not to confuse the sides, because inserting the card incorrectly physically is impossible due to the protective bevels, but the application of excessive force can break the plastic of the holder.

If you use two of them SIM-cards from different operators, it is recommended to insert a card with a faster communication standard in the main cell (Slot 1) (for example, in the main cell, 5G), To ensure maximum speed of mobile Internet.
Step-by-step instructions for removing the tray
The extraction process requires precision and proper positioning of the tool, so find a small circular hole on the bottom of your smartphone next to an oblong tray, and that's where you put the key.
Place your smartphone so that the screen looks up or down, but be sure to hold the device firmly with your second hand so that it does not slip out when you apply the force. Insert the clip point into the hole perpendicular to the body. The movement should be directed strictly inward, without distortion.
Press it moderately until you click it, and the spring mechanism pushes the tray outwards a few millimeters, and then you can gently tuck it in with your nail and remove it completely. Don't pull the tray right away without waiting for it to come out of the groove so you don't damage the side frame.
☑️ Proper removal of the tray
Physical installation SIM-map
After removing the tray, carefully examine its shape. The Xiaomi Mi 11 uses a two-sided or single-layer design, where the cards can be placed next to or above each other depending on the tray revision, but most often it is two cells in the same plane. Make sure that the bevelled corner of the card matches the bevelled angle of the notch in the tray.
Put it down. SIM-The gold contacts should look down to the phone contacts, not up. If the card is not tight or protrudes over the edges of the tray, it is installed incorrectly. The orientation of the chip plays a crucial role: the wrong position will prevent the phone from reading data.
After you've laid the cards, gently insert the tray back into the case. Make sure you don't confuse the top and bottom of the tray -- it only comes in one side. Push the tray until it's equal to the frame of the case and locks in with a slight click.
⚠️ Note: It is strictly forbidden to insert a tray if it is not inserted into it. SIM-map, or if the card protrudes outside the socket, this can cause the contacts inside the smartphone to break.

Primary network setting and Internet
After physically installing the cards and turning on the smartphone, the system will automatically try to determine the network parameters, usually this process takes from 30 seconds to 2 minutes, and the signal level indicators and the operator designation (for example, 4G, LTE or 5G) should appear on the screen in the upper status bar.
If the Internet does not work automatically, you may need to manually enter the settings of the access point (APN). This data can be found on the website of your operator or obtained through automatic SMS-message when you first register on the network. In the settings menu, select the desired SIM-Map and go to the "Access Points" item (APN)».
To check the quality of the connection, it is recommended to make a test call and open any web page in the browser. If the Calls are coming and the Internet is not working, check whether the traffic limit is exhausted and whether the data transfer is turned on in the “curtain” of the notifications.

⚠️ Warning: Do not use alcohol or aggressive chemicals to clean your contacts SIM-This can erase the special coating and cause the card to fail. Use only dry soft cloth.
Optimizing the two SIM-map
When using two active numbers, it is important to set priorities correctly. In the Xiaomi Mi 11, you can choose which card will be used for mobile Internet by default and which is only for calls. This helps save battery power, since the 5G module consumes more power.
There's also a smart switch feature available, and if the main card runs out of money or the signal goes missing, the phone can automatically switch to the second card to transfer data. SIM-cards and requires careful control of tariffs, so as not to go into the red on the second number.
