Modern smartphones, including the popular model Xiaomi Redmi Note 7, are equipped with trays for the use of the device. SIM-Users often face the need to replace a carrier, install a new memory card or simply clean contacts, but do not always know where the tool hole is. Owners of this model appreciate it for reliability and performance, but the design features of the case can be perplexed by the beginner, who for the first time took up a device with a hybrid slot.
Mistakes when trying to get a tray can damage the mechanism or even scratch the aluminum frame of the case. It is important to understand that the Redmi Note 7 uses a combined slot, which imposes certain restrictions on the use of two SIM cards and a memory card at the same time.
In this article, we will take a closer look at the process, from finding the right tool to installing the map correctly, and learn about design nuances that are not always obvious at first glance, and get answers to frequent questions from users. The security of your data and the integrity of the phone hardware are our top priorities, so we will pay special attention to the rules for the operation of mechanical elements.
Tools and workplace preparation
Before you start manipulating the case of the smartphone, you need to prepare the workspace. The ideal option is a flat surface of the table with good lighting, which will allow you to not drop small details and clearly see the location of the holes. It is recommended to cover the table with a soft cloth or use a special antistatic mat to avoid accidental scratches on the screen or the back panel when the device accidentally slips.
The main tool for removing the tray is a special metal clip that comes with the phone in the original box. If the brand clip is lost, it can be replaced with a regular stationery clip, straightening one of the ends, or using a thin needle, but with the latter you need to be extremely careful not to damage the mechanism.
⚠️ Warning: Never use shilling trays, nails or objects that are too thick to retrieve, as they can get stuck in the hole or damage internal sensors, resulting in expensive repairs.
It is also worth preparing in advance. SIM-The map is the right format if you're planning to replace it. The Xiaomi Redmi Note 7 uses the Nano-SIM standard, which is the smallest one at the moment. Make sure the new card is free of chips and damage and its chips are clean, as contact oxidation can cause signal problems.
Location of the slot for SIM-maps on Redmi Note 7
One of the design features of the Redmi Note 7 is the location of the SIM card tray on the bottom of the device, next to the USB Type-C connector and speaker. This is the standard solution for most modern smartphones, allowing you to maintain the tightness and aesthetics of the side faces. The tray is elongated and fits tightly to the body to prevent dust and moisture from entering the device.
Near the tray hole, you can often see a small icon that resembles a telephone tube or a rectangle with a dot that indicates the functional purpose of this hole. On Xiaomi, this indicator is usually made as a thin line or point located directly on or near the tray frame. It is important not to confuse this hole with a noise reduction microphone, which is also on the lower edge, but is round and extends deep into the body at an angle.
The tray in this model is hybrid, which means that you can install either two. SIM-card SIM-The design of the mechanism implies that the cards are installed in the same plane, so it is physically impossible to place two SIMs and flash memory at the same time. Understanding this feature will help to avoid attempts to force the extra card, which will inevitably lead to breakdown.
💡
To make it easier to find a hole in low light, turn on the flashlight on another device and illuminate the lower face of the phone at a sharp angle - shadows will immediately highlight the desired holes.
Step-by-step instructions for removing the tray
The process of removing the tray is simple enough, but requires confident and precise movements. Take a prepared paper clip or a special key to the right hand (if you are right-handed) so that the sharp end is directed perpendicular to the plane of the palm. Hold the tool to the hole on the bottom of the phone, making sure that it enters freely and does not rest against the walls.
Smoothly but with sufficient force, press the paper clip strictly perpendicular to the device body. You should feel a slight click or spring resistance, after which the tray will move out of the body by about 2-3 millimeters. Don't be afraid to press a little harder, the mechanism is designed for a certain force, but sharp jerks or pressure at an angle is unacceptable.
☑️ Tray extraction algorithm
Once the tray has jumped, remove the tool and gently pull the protruding edge with your fingers. Hold the phone firmly with your second hand so that it does not slip out as you pull the tray. If the tray does not extend after pressing, check the angle of entry of the tool is correct - it must be strictly perpendicular to the surface.
In some cases, the tray may get stuck due to dust or deformation. If you feel that the mechanism is jammed, try swaying the paperclip slightly from side to side without removing it completely to release the clamp. However, excessive diligence is not appropriate here, since you can damage the contacts of the reader inside the slot.
Features of the hybrid slot and the installation of cards
The hybrid slot in the Redmi Note 7 has a specific shape, where one side is designed for Nano-SIM and the other can accept either a second Nano-SIM or a microSD memory card. The tray itself usually has a schematic image showing how to orient the cards correctly. It is important to note that microSD cards often have a label on the back indicating their speed class, and this side should be pointed up or down according to the circuit.
Installation SIM-Make sure that the cut corner of the card matches the shape of the tray. The cards are inserted into the tray tightly, but without undue effort; they must lie in the same plane with the edges of the tray and not protrude over them. If the card is above the level of the frame, it can damage when closed or damage the reader mechanism itself.
| Type of card | Format | Location in the slot | Compatibility |
|---|---|---|---|
| SIM 1 | Nano-SIM | Left side (usually) | Main/DOP. sim |
| SIM 2 | Nano-SIM | Right-hand side | Unless there's an SD. |
| MicroSD | microSD/SDHC/SDXC | Right-hand side | Unless there's a SIM 2. |
| MicroSD | up to 256GB | Any free slot | Expansion of memory |
Once you've set the cards, gently push the tray back into the case, it should come in smoothly, without creaking or jamming. If you feel resistance, don't push, take out the tray and check if the cards are correct and if the debris has got inside the hole. A properly installed tray sits level with the body, leaving no gaps.
💡
The hybrid slot allows for flexible memory and communication management, but requires a choice of either two SIM cards or one SIM card and a memory card.
Solution: the tray is stuck or not retrieved
Sometimes users are faced with a situation where the tray is not retrievable even with the right tool, which can be caused by several reasons: oxidation of contacts, dirt, deformation of the body after a fall or factory failure of the mechanism.
First, try using a thinner and tougher tool, such as a special needle for the use of a slender and hardened tool. SIM-And you can put it in the hole, and you can push it to the end, and you can try to turn it around a little bit clockwise or counter-clockwise, and you can push the tray out at the same time.
⚠️ Warning: If the tray is not removed after several careful attempts, stop the exposure to avoid breakage. Contact an authorized service center where specialists will open the device without damage.
Another reason could be freezing or sticking together because of temperature changes if the phone is cold. Let the device warm up to room temperature for 30-60 minutes before trying again. The thermal expansion of materials can facilitate the movement of the mechanism.
What if the tray popped out, but the card is not?
Verification of work SIM-postcard
After successfully installing the map and turning on the device, you need to make sure that the system correctly identified the new carrier. On the lock screen or at the top of the display (status bar) should appear signal level icons and the network name. If the operator name is displayed “No network” or “SIM not detected”, additional diagnostics will be required.
Go to the phone settings by going down the Settings path → SIM-Maps and mobile networks: This section shows information about each card installed, its status and Internet settings. Make sure the switches for the respective slots are activated and the memory card is enabled as an internal or external drive if required.
If the phone sees the card but doesn't catch the network, try restarting the device. SIM-Xiaomi cards require a reboot to register with the operator's network, and it is also worth checking whether the map is worth it. PIN-code; if installed, the system will request it to be entered immediately after activation.
If problems persist, wipe the contacts. SIM-cards with a soft dry cloth or a swallow to remove possible oxide film. 5-7 Older cards may not support modern communication standards 4G/LTE, operator-operated.
