Installation of the second SIM-Xiaomi Redmi 5 maps: detailed guide

Xiaomi Redmi 5 remains a popular device due to its balance between price and functionality, but for many users, the question of expanding communication capabilities remains urgent. Often there is a need to use two numbers at the same time: one for personal calls and the other for work contacts or more profitable mobile Internet. Proper installation of the second SIM requires not only physical accuracy, but also an understanding of the design of the tray.

Unlike today’s flagship hybrid slots or eSIM, Redmi 5 uses a classic but reliable card placement mechanism. Errors when extracting or installing can damage the contacts or the tray itself, so it is important to strictly follow the algorithm of actions. In this article, we will discuss in detail the process of installation, setting communication priorities and eliminating typical errors that owners of this device face.

Before you start manipulating your gadget, you need to make sure you use the original paper clip or a thin tool that won't damage the spring mechanism. Wrong pressure can shift the internal contacts, and then the phone won't see the card even after you install it properly. Let's look at how to prepare for the procedure of replacing or adding a carrier.

Preparation for installation and types SIM-map

The first step is to check the format of your SIM-The Redmi 5 is exclusively based on the Nano-SIM format, which is the smallest one in existence today. If your card is Mini or Micro, it should be replaced in the operator’s cabin or gently trimmed along a special stencil line, if plastic allows it.

It is also important to check the status of metal contacts on the map, scratches, oxidation or contamination can cause unstable network operation. Before installation, it is recommended to wipe the chip with dry soft cloth, avoiding the use of aggressive chemical solutions that can damage the protective layer.

⚠️ Warning: Never try to insert SIM-card to the tray without turning off the phone, if the hot replacement function is not activated in the settings, since a voltage surge can theoretically damage the power controller, although in modern models the protection is improved.

Make sure the card tray is clean and free of deformities, often getting dust or pile from your pockets, which creates additional resistance when inserted. If you change operator, make sure the new card is activated and there are funds on the balance to complete the initial registration on the network.

Anatomy of the Xiaomi Redmi 5 tray

The design of the tray in Xiaomi Redmi 5 has its own features that distinguish it from older or, conversely, new models of the manufacturer. The slot is located on the top end of the device and is protected by a rubber cap to prevent dust and moisture. Inside there are two independent places for placing Nano-SIM maps.

It's important to understand the orientation of the cards when you lay them down. The tray has a bevel on one side, which corresponds to the bevel on the very side. SIM-Unlike some other smartphones, there is no separation between a "main" and "additional" card at the physical level - both slots are equivalent and support networks. 4G/LTE, However, any of these programs can be assigned priority.

If you look closely at the tray, you can see small notches for the fingers that help you extract the cards. You should not use sharp objects such as needles or scissors to pick inside the slot, as this can lead to short circuit contacts.

💡

If the tray enters with great effort, do not press, take it out and check if the map is turned over or if the debris has not hit the guides.

Step-by-step instructions for removing the tray

The process of removing the tray requires minimal effort, but it must be done at the right angle. On the top end of Redmi 5 is a small hole next to the rubber cap, which is where you need to insert a needle from the delivery kit or a sharpened clip.

Press the needle perpendicular to the body of the device until the characteristic click and easy extension of the tray. Do not press too hard or at an angle - this can lead to a jamming mechanism. Once the edge of the tray appears, carefully pull it with your fingers until fully removed.

• 📱 Place your phone down on a soft surface to avoid scratching when working.
• 🔍 Find the extraction hole on the upper end of the case next to the cap.
• 💡 Insert the tool strictly perpendicular and press until click.
• ✋ Carefully remove the tray with your fingers, without pulling sharply.

Once extracted, inspect the tray.If you've previously used only one card, the second slot may be closed with a plastic stub or be empty.Make sure you don't lose the first card while you're engaged with the second.

Proper installation second SIM-map

Now that you have the tray in your hands, you need to properly place the second one. SIM-Take the card down with the chip (contacts to the ground) and navigate the angle bend. In Redmi 5, both cards are placed in the same level, but in different cells, so it's important not to confuse the sides.

Put the card in the appropriate recess. It should be tight and not wobbly. If the card protrudes above the edges of the tray, it means that it is inserted incorrectly or has the wrong format. After stacking both cards (or one, if the second cell is still empty), you can return the tray to the phone.

Put the tray back in just one position, the way it was removed. If you feel resistance, don't use force. Turn the tray over the other side and try again. The mechanism has fool protection, but the extra pressure won't do any good.

⚠️ Warning: Make sure the rubber plug fits tightly to the body after the tray is installed.A leakage disorder can cause moisture to enter the device when used in the rain.

Initial configuration and activation in the system

After physically installing the second SIM and turning on the smartphone, the operating system MIUI It will automatically detect a new device. It will show a notification of a found device. SIM-The system will suggest assigning a name (e.g., "Worker" or "MTS") for easy identification in the future.

Next, you need to configure the parameters for using the cards. → SIM-You can choose which card will be used for mobile Internet by default and which for voice calls. This is a critical step to save traffic and money.

For the second SIM, it often makes sense to turn off data transfers, leaving only voice and SMS to avoid accidental traffic consumption from the main balance, and you can set up a standby mode: if one card is busy talking, the second may be unavailable or forward calls.

Setting priorities and mobile internet

The flexibility of setting up two Sims in Xiaomi allows you to create use cases, for example, you can set a rule to “always ask” when making a call, to choose which number to call from each time, or assign specific contacts to call only through a specific SIM.

Particular attention should be paid to the setting 4G. At Redmi. 5 both slots support 4G, But they can't run at high speed at the same time. LTE, And the second one goes into 2G/3G You can switch the priority slot for the Internet in one click through the notification curtain.

• 🌐 Select the main map to transfer data in the settings menu.
• 📞 Assign a preferred SIM for default voice calls.
• 💬 Set up a card to send. SMS, If you don't want to choose every time.
• ⚙️ Activate the “Limit Traffic” function for secondary SIM.

Remember that when you actively use the Internet on one SIM, the second can temporarily lose the network or go into standby mode, which is normal behavior for most modems in this class.

💡

Proper setting of SIM card priorities allows you to save up to 30% of the budget for communication, using tariffs of different operators in the optimal way.

Solving Typical Problems and Errors

Users often face a situation where the phone says “No”. SIM-If that doesn't work, check if the card is inserted correctly in the tray and if it has moved during transportation, the first thing you need to do is reboot the device.

Another common problem — عدم coming SMS Or you can call a second SIM, and it could be related to your network settings. → SIM-map → Selecting the network by turning off the automatic mode. Sometimes the automation gets mistaken and clings to the weak signal.

If the problem persists, it may be a software firmware failure, which can help reset network settings (not data, but network settings), which will return all APN parameters and network preferences to factory values, which often resolves driver conflicts.
