How do you put it in? SIM-Map Xiaomi Redmi: the full guide

Installing a mobile operator card is the first and most important step after buying a new smartphone. Owners of Xiaomi and Redmi devices often face a variety of tray designs that vary from model to model. Installing the wrong one can lead to the device not seeing the network, or, in the worst case, mechanical damage to the contacts inside the socket. In this article, we will discuss all the nuances of the procedure for different generations of phones.

Modern Chinese smartphones use standard nano-SIMs, but the physical location of the slots can be very different: somewhere it is a retractable tray on the side, and in rare cases, a removable lid on the back. Careful study of the design of your particular device before you start manipulating will help to avoid errors. We will look at the universal methods and specific features characteristic of current models.

Before you pick up a paperclip, make sure you understand what format your device supports. Most modern devices work exclusively with nano-SIM, whereas older models could support micro-SIM or even standard SIM. Installing an inappropriate size card without a special adapter or trimming can lead to a tray getting stuck and breaking the extraction mechanism. Let's move on to the preparation of the necessary tools.

Tool preparation and tray type determination

You'll need a minimal set of tools to install the card successfully. You'll usually have a metal needle attached to your phone, but if it's lost, you'll need a paper clip or a thin pin. The key is that the tool is thin enough to go in the hole, and strong enough not to bend when pressed. The sharp tip is crucial.

The first thing you need to do is to identify the type of tray in your Redmi model. Visually look at the ends of the device. If you see a narrow slit with a hole in the middle or on one side is a retractable tray. If the back cover of the smartphone is removed completely, the slot is underneath, often hidden behind or next to the battery. In modern Xiaomi models, the former is the predominant option.

It is also important to understand the configuration of the slot. The tray can be combined (hybrid), where the second socket can be placed or a second socket. SIM, In other models, the slots are separated, and the installation of the memory card does not affect the number of available slots. SIM-A hybrid slot requires the user to choose between two SIMs or one SIM plus a flash drive.

• 🔍 Carefully inspect the ends of the smartphone in good lighting to find a hole to extract.
• 📏 Make sure yours is yours. SIM-The card is in nano-SIM format (the smallest standard).
• 🛠️ Prepare a paper clip or needle, making sure its tip isn't too thick.
• 🧹 Wipe the card contacts with a soft dry cloth if they show contamination.

⚠️ Warning: Never use a tray of scissors or other sharp objects with a wide sting to extract it, which can damage the latch mechanism inside the case and the tray will stop fixing or get stuck forever.

Step-by-step instruction: installation in the drawer tray

The retractable tray installation process is standard for 95% of modern Redmi Note and Mi smartphones. First, take a pull tool (a clip or needle) and find a round hole on the device's frame. It's usually located on the bottom or top end. Push the tool perpendicular to the body and press with moderate force until clicked.

Once you press the tray, it should extend a few millimeters. Carefully pull it with your fingers to extract it completely. Place the tray on a flat surface with a drawing upwards. You will see notches that are shaped to match the size of the nano-SIM. Modern models often use an anti-sim tray mechanism to prevent the card from being installed incorrectly.

Take yours. SIM-And you can match it with the notch in the tray, and you can notice the angle that's beveled, it's got to match the shape of the cutout, and if the card is flat and it doesn't protrude beyond the edge of the tray, you're doing the right thing. Don't make an effort if the card doesn't come in freely. Then carefully insert the tray back into the phone to the end.

It's important to keep track of the orientation of the tray when you return to the case. If you try to insert it on the other side or upside down, it just won't go in. The mechanical pressure here is unacceptable. Make sure that the tray frame is in the same plane as the smartphone case after installation.

Features of installation in models with removable cover

Some low-end Redmi models (such as the older versions of the 8A, 9A or Go series) still have a removable back cover. In such devices, the process looks different. First, you need to find a special cutout (usually in the bottom corner on the end) and a nail or flat tool to tamper with the lid, removing it completely.

Once the lid is removed, you will see an interior space that opens up in front of you. If the battery is removable, it will usually need to be removed to access SIM slots, which are often under the battery. In some designs, slots are located next to the camera or speaker and do not require the battery to be removed. Be careful not to touch the golden contacts inside the phone with your fingers.

Put it in. SIM-The card is placed in the appropriate slot, observing the orientation indicated by the icon next to the connector. Usually, the bevelled corner of the card should look outward or upward, depending on the model. After installing the card (and memory card if necessary) return the battery to its place (if it was removed) and snap the back cover to a characteristic sound around the perimeter.

💡

Before installing the cover, check if the protective film has hit the new one. SIM-cards inside the slot - it can interfere with contact.

Make sure the lid is sealed, without gaps. A loose fit can cause dust to enter the connectors or even cause the phone to fail to turn on if the battery contacts do not close properly.

Dual SIM configuration and memory card

Most users use two numbers, and Xiaomi smartphones are great at managing two active numbers. SIM-However, as mentioned earlier, in hybrid slots, the second connector is divided between the second SIM and the memory card, and you have to choose which is more important: extended memory or the second number.

If you use two of them SIM-maps, system MIUI You can assign one card to the default call and another to the mobile Internet, and you can also use the smart switch feature, where, when there's no network on the main card, the phone automatically uses the second card to make calls.

When using a microSD card in a hybrid slot, the second SIM-The system will only detect one SIM and drive, and this limitation is related to the design of the motherboard and the contact group.

If you are actively taking high-resolution photos or downloading a lot of media, having a separate slot for the memory card will be a priority, otherwise, for business users, having two active communication lines is more important.

Network settings after installing the map

After physically installing the map and turning on the phone, the Android system must automatically identify the new operator. The network icon (4G, LTE, 5G) and signal level will appear on the screen at the top. If this does not happen, or the icon of the crossed-out SIM appears, you need to check the software settings.

Go to the Settings menu, select a paragraph SIM-Maps and mobile networks. Here you'll see a list of maps installed. Make sure the switch opposite the card you want is activated (blue or green). If the card shows as "Unknown" or "No network", try rebooting the device.

Mobile Internet may require manually configuring the APN hotspot to work properly. Usually, this data is automatically pulled up, but sometimes it needs to be entered manually, after receiving instructions from the operator or finding it on its website. From the mobile network menu, select your SIM, go to APNs, and create a new point with your operator's parameters.

Don’t forget that for networking 4G/5G yours SIM-The card must support these standards. If you use a very old card issued by the 10 Years ago, it could only work in a 2G or 3G. In this case, it is advisable to contact the communication salon for a free replacement with a modern one. USIM.

Addressing common problems

Sometimes users are faced with a situation where the phone writes "No Service" or constantly searches for the network, this can be due not only to a wrong installation, but also to a software failure. Try to turn on and off the flight mode (Air mode).

Another common problem is contamination of contacts. SIM-You can make an oxide film or you can build up fat from your fingers, and you can take a soft cloth that's slightly soaked in alcohol, and you can wipe the contacts gently. You can let them dry for a few seconds before you put them in.

If the tray SIM-cards fall out on their own or dangle, perhaps broken locking latch inside the mechanism. In this case, you can try to gently bend the tongue on the tray itself (if it is metal and allows), but it is better to contact the service center for replacing the tray to avoid moisture getting inside.

• 📶 Check if Do Not Disturb mode or restrictions for specific numbers are activated.
• 🔄 Reset network settings if the problem is programmatic.
• 🔌 Make sure that the phone is not in the area of poor signal reception (basement, elevator).
• 📱 Check for system updates MIUI, which may contain modem corrections.

⚠️ Attention: If your phone suddenly stops seeing the SIM card after falling or getting moisture, do not try to dry it with a hair dryer or put it on the battery. High temperature can damage the adhesive seals and the screen.
