What are they? SIM-The cards support Xiaomi phones

Before inserting a card, it is important to make sure that the format is compatible with your smartphone. Modern Xiaomi devices support three types of SIM:

  • 📱 Nano-SIM (4FF) — standard for all models with 2016 Size of the year: 12.3 × 8.8 × 0.67 mm.
  • 🔄 Micro-SIM (3FF) — Older format, found in old Redmi 1S/2S (2014–2015 Size: 15 × 12 × 0.76 mm.
  • 📲 eSIM – virtual card, available in flagships (Xiaomi) 13/14 series, Mix Fold 2/3). Requires operator support.

If you have a Mini-SIM (2FF) card (large, like the old push-button phones), you'll have to trim it to a nano or replace it with an operator. Using adapters (e.g., micro→nano) can lead to poor contact and network loss.

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.

  1. Turn off the phone. This will prevent damage to the contacts during installation, except for the hot-switched SIM (Redmi 9A, POCO C40) models, where the slot can be opened on the device on.
  2. Find a slot for SIM-In most Xiaomi, it's on the left end (if you look at the screen), and in the Mix Fold and Black Shark models, it's on the top end.
  3. Remove the tray: Insert the paperclip into the hole next to the slot before clicking. Pull the tray over yourself in a smooth motion (don't pull out sharply!).

If the paperclip doesn't work, try the following methods: 1. Use thicker wire (such as an unbended stationery brace). 2. Heat the phone's case with a hairdryer (no more than 60°C) - sometimes the tray jams due to temperature changes. 3. Contact the service center if the tray is bent or broken. Self-attempts to pull it out with tweezers often damage the socket.

Common Mistakes and How to Avoid Them

Even experienced users sometimes make mistakes when installing SIM-Here are the most common ones and the ways to solve them:

  • 🔄 The card is upside down. Symptoms: the phone can't see. SIM, or it is defined as "null and void." Solution: flip the card with the contacts down (they must face the back of the phone).

💡

Before traveling abroad, check to see if your Xiaomi supports local carrier frequencies. In the U.S., for example, many Redmis do not work with Verizon networks due to a lack of CDMA support.

Some Xiaomi smartphones have unique nuances when working with SIM-Let's look at the most popular models:

Redmi Note 12/13 series and POCO X5

These phones feature a hybrid slot where the second slot can be used either under a second SIM or under a microSD.

  • If you need two SIMs, insert both into slot 1 and slot 2 (the microSD won’t work).
  • If you need one SIM + memory card, use SIM slot 1 and microSD slot 2.

Note: In the Redmi Note 12 Pro+, the microSD slot supports cards up to 1TB, but read/write speeds are limited by UHS-I.

Xiaomi 13/14 Pro and Mix Fold 3

The flagship models support eSIM, but with the following reservations:

  • In China, eSIM only works with local operators (China Mobile, Unicom).
  • In global versions (13 Pro Global), eSIM supports most European operators (e.g. Vodafone, T-Mobile).
  • The activation of eSIM requires the Internet (Wi-Fi or mobile data of another SIM).

Redmi A2 and POCO M6

Budget models have a single slot for nano-SIM + a separate slot for microSD.

  • Don’t confuse slots – microSD won’t be inserted into a SIM slot (and vice versa).
  • When buying, check if the model supports VoLTE (some regions sell versions without this feature).
  • Test the SIM on another phone, and if it doesn't work, there's a problem in the card (see the operator).
  • Update the software. Go to Settings → About Phone → System Update and install the latest firmware.
  • Reset your network settings. Go to Settings. → SIM-maps and mobile networks → Resetting network settings.

If none of these methods worked, the problem could be hardware:

  • 🔌 Oxidation of contacts (often after moisture is ingested) Solution: Clean the contacts of the tray with alcohol.
  • 🛠️ Slot damage (e.g. after phone fall) Solution: Replace the slot in the service center (~500-1500 rubles.).
  • 📡 Communication module malfunction (phone does not catch the network even from another one) SIM). Solution: Diagnostics and repairs (~2000-5000 rubles.).

⚠️ Note: If you drop your phone in water, don’t try to put it in right away. SIM-Allow the device to dry completely (at least 24 hours in rice or silica gel), otherwise a short circuit may damage the communication module.

How to activate eSIM on Xiaomi

Virtual SIM (eSIM) is becoming more popular, but its setting is different from a regular card. To activate on Xiaomi, follow the following steps:

  1. Most Russian operators (MTS, Beeline, Tele2) support eSIM, but it must be ordered separately (via the application or office).
  2. Connect to the internet. eSIM is activated online, so you need Wi-Fi or mobile internet (with another SIM).
  3. Open Settings: Go to Settings → SIM-maps and mobile networks → Add eSIM. Select "Add with QR-code" or "Input data manually".

Scan it. QR-code

  • SM-DP+ Address (Activation Server Address)
  • Activation code.
  • Confirm installation. The phone will download the eSIM profile (reboot may be required).
  • Set your priorities SIM. B Settings → SIM-Choose which cards you want. SIM Use for calls/internet by default.

Important nuances:

  • 📱 You can install multiple eSIMs on a phone (for example, for work and personal calls), but only one phone will be active at the same time.
  • 🔄 When resetting the phone to factory settings, the eSIM is saved, but it may require re-activation.
  • 🚫 Some carriers (e.g. MegaFon) do not support eSIM on Xiaomi due to firmware limitations.

💡

If your carrier doesn’t support eSIM but you need a second line, consider virtual number services (like Dingtone or Google Voice) that run over the internet and don’t require a physical SIM.
