Installation of two SIM and memory card in Xiaomi Redmi Note 7

Xiaomi smartphones have long proven themselves as reliable devices with excellent value for money. The Redmi Note 7 model has become a real bestseller, offering users a glass case, a powerful camera and a modern design for affordable money. One of the key issues in the initial configuration of the gadget remains the correct organization of communication and expansion of built-in storage.

Owners often need to use multiple carrier numbers to separate work and personal calls, and install a memory card to store photos and videos. Xiaomi Redmi Note 7 has a combined slot that requires care when installing modules. Incorrect installation can lead to the fact that the device will not see one of the SIM cards or drive.

In this article, we will discuss in detail the process of extracting the tray, determine the purpose of each contact and analyze the possible nuances of working with a hybrid slot. Following simple rules will help you avoid mechanical damage and immediately start using all the functions of your smartphone to the fullest.

Preparation of the workplace and tools

Before you start to physically affect the body of the smartphone, you need to ensure comfortable working conditions. Good lighting is not just a recommendation, but a necessity, since the tray for SIM cards is miniature, and to consider the location of contacts in dim light will be extremely difficult.

You only need one tool to do the operation, a special metal clip that comes with the device. If the original paper clip is lost, you can use a thin needle or an unbended stationery clip, but you need to be extremely careful not to scratch the case or break the extraction mechanism.

It is recommended to cover the table with a soft cloth or prepare a special mat. This is done in case you accidentally drop the tray or the SIM card itself: a soft surface will prevent scratches on the glass back cover or screen, and also prevent miniature parts from bouncing far to the side.

⚠️ NOTE: Do not use knives, a sewer or other sharp objects with a wide blade to remove the tray. You may damage the latch mechanism inside the case or accidentally slip and scratch the frame of the smartphone.

Features of the design of the Redmi Note 7 tray

The Redmi Note 7 tray is located on the bottom end of the device, to the right of the USB Type-C charging connector. Structurally, it is a combined module that allows you to flexibly configure the connection configuration. It is important to understand that these are not three independent slots, but a system with certain limitations.

On one side of the tray is a place to install one nano-SIM card. On the back there are two compartments: one for the second nano-SIM SIM card and the other for the microSD memory card. This is where the main feature is that you can't use two SIM cards and a memory card at the same time.

The contacts on the tray are shaped and positioned, the corners of the card cutouts are beveled, which is a physical limit to the wrong setup, and if the card doesn't fit into the bay smoothly and freely, you don't have to push -- you've probably got the sides mixed up or the orientation map.

Step-by-step instructions for installing two SIM-map

If you don’t need to expand your memory via microSD, you’ll want to use two SIM cards, which allows you to fully leverage your smartphone modem’s capabilities to work on 4G networks on both numbers.

First, take a paper clip and find a small hole on the end of the smartphone. Carefully, but with a confident press, insert the tool into the hole perpendicular to the body. The tray should go out. Take it with your fingers and completely remove it from the device.

Place the tray on a flat surface with the front facing up (where a logo or model is usually written). In the recess on one side, install the first SIM card. Then turn the tray over with the back side. In the compartment intended for the second SIM card (usually shaped like a nano-SIM circuit), install a second communication module.

Make sure the cards are in their recesses and don't protrude beyond the edges of the tray. If done correctly, you can gently insert the tray back into the smartphone before the characteristic click. Once the device is turned on, two network icons should appear at the top of the screen.

Using a microSD card instead of a second SIM

Many users prefer to have one primary number but lack built-in storage for high-resolution photos or heavy gaming, in which case the second slot on the back of the tray is used for a memory card.

The installation process is similar to the previous one, but instead of the second SIM card, a microSD card is installed in the corresponding compartment on the back of the tray.

Once the memory card is installed and the smartphone is turned on, the MIUI system usually automatically recognizes the new drive. If this does not happen, check that the contacts are correctly installed. The memory card also has a bevelled angle that should match the shape of the compartment.

💡

Use a UHS-I or higher-speed memory card from trusted brands (Samsung, SanDisk, Kingston). Cheap cards from unknown manufacturers can run slowly, causing delays when saving photos or running applications installed on an external medium.

Setup of two SIM cards in MIUI

Once the modules are physically installed, the software part needs to be configured correctly. Android’s MIUI shell provides flexible tools to manage two numbers. Basic setup is automatic, but manual adjustments are often useful.

To manage settings, go to the Settings menu and select the item SIM-You'll see a list of maps installed here, each of which you can name (e.g., "Work" or "Personal") and choose a color to distinguish visually in the interface.

You can assign one card to the primary mobile Internet and leave the other card for calls only, and there is a feature that allows you to always specify which card to make a call from when dialing.

Common problems and methods of their solution

Sometimes, users are faced with a situation where the smartphone does not see one of the cards or memory cards, most often the reason lies in the oxidation of contacts or improper installation. Try to remove the tray and wipe the contacts of the SIM cards and the tray with a soft dry cloth.

Another common problem is format incompatibility: Redmi Note 7 uses only nano-SIM cards. If you try to insert a larger card carved from an old SIM, it may not be in contact with the tray tracks.

If the phone says "Card not installed" or "Formatting required" for a microSD, check the file system. Android-based smartphones work best with an exFAT or FAT32 file system. Formatting can be done through the storage settings menu, but this will delete all data from the card.

⚠️ Warning: Never remove a SIM card tray or memory card while recording data or an active phone call.This may cause file system damage or loss of unsaved data.
