Xiaomi Redmi Note 7 is still a popular device even years after its release, but many users are faced with a basic problem: how to properly extract the device. SIM-Unlike the flagship models with an electronic slot, it uses a classic physical tray that requires accuracy. This article will help you understand all the nuances - from the preparation of tools to the solution of emergency situations, when the SIM "jammed" or the tray is not pushed out.
We will look at not only the standard procedure, but also alternative methods (for example, without a paper clip), and also understand why you can not use needles or toothpicks - this is a common error that leads to failure of the mechanism. Special attention will be paid to the features of the hybrid slot in Redmi Note 7, where two nano-SIMs or one SIM + microSD are simultaneously placed. If you plan to replace the SIM or install a memory card, this instruction will be your reliable guide.
Preparation: What will be needed to extract SIM-map
Before you start extracting, make sure you have everything you need. The main tool is the key to remove the tray (companying with the phone). If it is not, a paper clip will do, but not any one: it must be straightened so that the tip is straight and not too thick (a diameter of 0.8 mm).
Also prepare:
- 📱 Xiaomi Redmi Note 7 (Switched off – it is necessary!)
- 🔧 Key-clip or original tool from the set
- 📦 Clean wipe or microfibre (for cleaning the tray and contacts)
- 🔦 Lantern (if the lighting is weak - a hole for extracting a small one)
Important: If you are planning to replace SIM-The Redmi Note 7 supports only nano-SIM (3FF). If you have a different size card, you have to cut it or replace it in the operator's cabin, and you're not allowed to use adapters inside the tray, which can damage your contacts.
⚠️ Warning: Never try to remove the tray by force if it doesn't respond. Applying excessive force can break the spring mechanism inside the phone, and then you need to disassemble the device in the service center.
Where is the slot for SIM-Maps in Redmi Note 7
Xiaomi Redmi Note 7 tray for the SIM-The card is located on the left side of the phone (when you look at the phone screen facing you), it is easy to recognize by a small hole next to the volume buttons. SIM or pictogram of the card, but in the Redmi Note 7 there are no such designations - focus only on the shape of the hole.
Structurally, the slot is designed as a hybrid: it supports:
- 📶 Two nano-SIM (Dual Mode)
- 📱 One nano-SIM. + one microSD up to 256 GB)
This means that if you use two SIMs, you can't install a memory card, and vice versa. When you remove the tray, you should pay attention to the design: it has two slots with metal contacts and one slot without them (for microSD). You can't confuse the sides - there is a notch on the tray that matches the shape of the socket in the phone.
| Tray configuration | Supported combinations | Limitations |
|---|---|---|
| Slot 1 + Slot 2 | Two nano-SIMs (4G+4G or 4G+3G) | It is impossible to use a microSD. |
| Slot 1 + microSD | One nano-SIM + memory card | Second SIM is off. |
| Only a microSD. | Memory card without SIM | The phone won't catch the network. |
💡
If you change configurations frequently (two SIMs, then SIMs + flash drives), keep the tray clean. Dust and small debris on the contacts can cause network failures or memory card reading problems.
Step-by-step instructions: how to remove SIM-Map from Xiaomi Redmi Note 7
Now, let's get to the process itself. Follow the instructions carefully to avoid the typical mistakes.
- Turn off your phone. It's a must! Removing the SIM on your device may damage your contacts or cause your modem to malfunction. Wait until the screen is completely turned off.
- Find the hole to extract. As mentioned earlier, it's on the left side. Hold the phone up to the light to see the hole precisely, which should be strictly perpendicular to the body.
- Put a key or a paper clip in. Carefully, without pressing, put the tip of the tool into the hole all the way up, and you'll feel a little resistance -- that's okay.
- Press until you click. With the right force, the tray will extend 1-2 mm. You don't have to push hard! You have to press it lightly, but with confidence.
- Remove the tray completely. When it comes out of the nest, pull it with your fingers. Don't pull it, pull it out smoothly so you don't bend the contacts.
If the tray is not pushed out the first time, check:
- 🔍 Did you find the hole correctly (sometimes confused with a microphone connector).
- 🛠️ Is the stainless stain on the sleeve (the sleeve) straight).
- 🔋 Is the phone turned off (on the device the mechanism may be blocked).

What to do if the tray is jammed or does not come out
It's not uncommon for the tray to fail at all, and it can be caused by things ranging from debris to mechanical damage.
1.The tray does not respond to the pressing of the key
If nothing happens when you press the hole:
- 🔄 Try turning the paperclip over and pressing from a different angle (sometimes the hole gets clogged with dust).
- 💡 Light the flashlight - perhaps the tool does not fall into the slot of the mechanism.
- 🛑 Don't use needles or pins! they're too thin and can fall inside, damaging the board.
2.The tray moved out halfway and got stuck
It's one of the most unpleasant situations. Don't pull it with pliers.
- 🔧 Carefully swing the tray left-right, at the same time pulling it on yourself.
- 🧴 Put the drop on. WD-40 or alcohol on the visible part of the mechanism (if the tray sticks out of the nest).
- 📞 If nothing works, contact the service. Self-attempts can aggravate the problem.
⚠️ Warning: If you notice that the spring mechanism inside the phone is bent or broken after removing the tray, do not try to repair it yourself. Improper repairs can result in the loss of warranty (if it is still valid) or damage to the motherboard.

How to insert it correctly SIM-map
Putting the SIM back in requires as much precision as retrieving. Here are the key points:
- Check the tray for damage, make sure it's free of dents, scratches or dirt, and the contacts must be clean and shiny.
- Place it. SIM-Nano-SIM is placed in the groove with the contacts down, beveled angle to the notch on the tray. If you use microSD, it is placed in the third groove (no contacts).
- Make sure you're orientationd correctly. The map should be free, without tension. If you have to push, it's inserted incorrectly.
- Put the tray all the way up. Press it with your finger until it snaps. You'll hear a characteristic click.
After installation, turn on the phone and check:
- 📶 Whether the network appeared (operator icon in the status bar).
- 📞 Can I make an outgoing call.
- 📥 Will he? SIM-map in settings (Settings) → SIM-maps and mobile networks).
If the network does not appear:
- 🔄 Reboot the phone.
- 🔧 Check if the SIM is properly installed (sometimes it shifts when the tray is inserted).
- 📡 Manually select the operator in the network settings.

Frequent Mistakes and How to Avoid Them
Even in this simple procedure, users often make mistakes that lead to breakdowns.
| Mistake. | Effects of consequences | How to avoid |
|---|---|---|
| Use a needle instead of a paper clip | Contorted extraction mechanism, hitting the needle inside the body | Use only the original key or an unbended clip with a diameter of 0.7-0.9 mm |
| Removing the tray on the phone turned on | Modem malfunction, contact damage | Always turn off the device before manipulation |
| Installation SIM-pin-up | Map is not recognized, possible scratches on contacts | Check orientation: contacts should be from below |
| Use of force in a jammed tray | Breakdown of the spring mechanism, cracks on the body | Contact the service at the first sign of snag |
Another common problem is getting moisture into the slot. If the phone has been in water or in the rain, be sure to dry it off for at least 24 hours before removing the SIM, and moisture on the contacts can cause corrosion or short circuit.
Also avoid:
- 🧲 Storing a tray next to magnets (this can magnetize metal parts).
- 🔥 Exposure to high temperatures (for example, leaving the phone in the sun with the tray removed).
- 🧴 Use of alcohol-containing liquids for cleaning contacts (dry microfiber is sufficient).
