SIM-The Redmi Note 13 Pro+ Xiaomi 14 Ultra, where the order of installation affects the priority of networks. SIM Xiaomi or are afraid to break something – this guide is for you.
What are they? SIM-Cards are suitable for Xiaomi phones
Since 2018, all Xiaomi smartphones support exclusively nano-SIM (4FF) format, which means that if you have an old card the size of a bank (mini-SIM) or slightly smaller (micro-SIM), it will have to be trimmed or replaced in the cabin of the operator, using adapters or homemade croppings can damage the slot contacts or break the locking mechanism of the card.
It is also important to consider the type of slot in your model:
- 📱 Single slot – only one nano-SIM (found in budget models, for example, Redmi) A2).
- 🔄 Hybrid slots - nano-SIM + MicroSD (you can choose either the second one) SIM, It's either a memory card, but not at the same time. POCO X5 or Redmi Note 12.
- 📶 Double slot – two nano-SIMs without microSD installation (e.g. Xiaomi) 13T Pro).
To determine the type of slot, check the model specifications on the official Xiaomi website or look at the tray: if it has an SD tag, it is a hybrid variant. Also pay attention to the support of standards: modern smartphones work with 4G/5G, but the second SIM can be limited to only 4G (this is indicated in the specifications).
Preparation for installation: security tools and measures
Before you start the installation, prepare everything you need.
- 🔧 Paperclip or key to remove the tray (company with the phone; if lost, an unbended paperclip will fit).
- 📱 Nano-SIM (stripped to a template or new from the operator).
- 🔍 Flashlight (will help to see the slot in poorly lit places).
- 🧴 Alcohol wipes (to clean the contacts of the card and slot in case of suspected oxidation).
It is critical to work on a flat surface (like a desk) so that the phone does not fall when you remove the tray. If you use a case, it is better to remove it - it may interfere with access to the slot. Also make sure that the phone is turned off: although most Xiaomi models support hot SIM replacement, the risk of damage to contacts with power on remains.
⚠️ Warning: Never use sharp objects (knives, needles, toothpicks) to extract the tray. This can damage the locking mechanism or scratch the phone's body. If the key does not enter the hole, check if dirt has hit the tray - carefully clean it with compressed air.
If you are installing SIM for the first time, look at the card side: the chip must be downwards and the bevelled angle must match the tray shape. Incorrect installation can cause the phone to fail to see the network, and re-extracting the card increases the risk of damage.
Step-by-step instruction: how to insert SIM-map
The installation process is the same for most models, but there are nuances depending on the location of the slot: in new flagships (for example, Xiaomi 14), it can be on the upper edge, and in budget series (Redmi, POCO) – on the side.
Turn off your phone (optional, but recommended)
Remove the case (if any)
Prepare a paper clip/key and SIM-map
Check the side of the card installation (chip down)-->
- Find a SIM slot. It's usually marked by a small hole next to the tray. On some models (such as the Xiaomi 13 Lite), the slot is hidden under the lid, you need to carefully tweak it with a mediator.
- Remove the tray. Put the paper clip in the hole before you click. The tray will extend 1-2 mm — pull it with your fingers. Don't put too much effort: if the tray doesn't come out, check if the paper clip is skewed.
- Install. SIM-Place it in the appropriate slot on the tray (for hybrid slots, select the side). SIM1 or SIM2). Make sure the card fits tightly to the stops.
- Put the tray back in place. Put it in before you click, make sure it's up straight. If the tray is skewed, the phone may not recognize the SIM.
Turn on your phone and wait for the network indicator to appear (usually 10–30 seconds). If the network does not appear, restart the device or check if the card is inserted correctly. In dual SIM models (Xiaomi 13 Pro, Redmi K60), you may need to select a priority card for calls in the settings.

Features of installation in popular Xiaomi models
Despite the similarities, some Xiaomi models have unique nuances, and we have collected them in a table:
| Model | Slot type | Location. | Features |
|---|---|---|---|
| Xiaomi 14 / 14 Pro | Double nano-SIM | Upper edge | Support 5G both SIM, But the priority network is selected manually in Settings → SIM-maps and mobile networks. |
| Redmi Note 13 Pro+ | Hybrid (SIM + microSD) | Left face | When using two SIMs, the memory card is not supported. The slot is sensitive to dust - periodic cleaning is recommended. |
| POCO X5 Pro | Hybrid | Lower facet | The tray is fixed less rigidly than in other models - there are often cases of spontaneous extension during impacts. |
| Xiaomi 13 Lite | Double nano-SIM | Under the removable lid | It requires a gentle lid tweaking with a mediator. Don't use metal objects, there's a high risk of damaging antenna lines. |

If you change often SIM-cards (for example, on trips), buy a magnetic key for a tray - it is more convenient than a paper clip and does not scratch the body.
Common Mistakes and How to Avoid Them
Even experienced users sometimes make mistakes when installing SIM, and here are the most common:
- Map format mismatch: Trying to insert a micro-SIM without an adapter or a hand-cut nano-SIM often causes the phone to fail to see the network, so you can either order a new card from the operator or use a professional cutter.
- In hybrid slots, it's easy to flip the tray and insert the SIM into the microSD connector, and the consequences are that the phone doesn't recognize the card, and if you force the insert, you can bend the contacts.
- Use force to remove the tray. If the tray doesn't come out, don't push harder, check if there's any debris in the mechanism.
- Ignoring the sloping angle. SIM-The card must enter the groove in only one position. If the angle does not match, the contacts will not touch the chip.
Another common problem is contact oxidation, especially if the phone was used in wet conditions, signs: the network disappears periodically, or the phone only sees the SIM after rebooting. Solution: gently wipe the contacts of the card and slot with an alcohol wipe. Do not use abrasive materials (for example, eraser) - they will damage the gilded coating.
⚠️ Attention: If after installation SIM phone makes a mistake "SIM-The card is not supported, this may mean that the card is blocked by the operator (for example, when lost) or is incompatible with the networks of your country.

- Check the installation correctly. Remove the tray and make sure the card is down the chip and does not protrude beyond the edges.
- Clean the contacts. Wipe the SIM chip and the contacts in the slot with a lilac-free cloth soaked in alcohol.
- Check your network settings. Go to Settings. → SIM-Maps and mobile networks and select the operator manually.
- Update your firmware. In rare cases, the problem is caused by a software failure. Check for updates in Settings → About Phone → System Update.
- Test the card on another phone, and if it doesn't work there, the operator has a problem, call the phone.
If none of these things worked, the slot itself might have failed, in which case you can contact Xiaomi’s service center, and self-repairing the slot can damage the motherboard, especially in models with an integrated antenna next to the connector (such as the Xiaomi 12S Ultra).

How to care SIM-map and slot in Xiaomi
To avoid problems in the future, follow simple rules:
- 🧼 Clean the slot from dust regularly (every 3-6 months) with compressed air or a soft brush.
- 🚫 Avoid moisture. Do not remove the tray in wet conditions (for example, in a bath or in the rain).
- 🔄 Don't change. SIM Every retrieval of the tray increases the risk of debris getting into the machinery.
- 📦 Keep the spares. SIM in a dry place, away from magnets and heat sources.
If you travel frequently and use local SIM-Many new Xiaomi models (such as Xiaomi 13 and newer) support virtual cards. This will save you from having to physically change the card. SIM To activate eSIM, contact your operator, most of whom provide this service for free.

If after a hit the phone stopped seeing the network, do not try to disassemble the device yourself - this can aggravate the problem. In Xiaomi service centers, replacing the slot is done in 1-2 days, and it is cheaper than repairing the motherboard.
