1 How many SIM- cards in Xiaomi Mi 5: official data

According to Xiaomi specifications, all versions of the Mi 5 (2016) are equipped with one physical slot, but with different configurations:

• 📌 Mi 5 Standard/Pro: Hybrid slot — either 2 nano-SIM or 1 nano-SIM + MicroSD (up to 128 GB). Dual SIM (DSDS support is officially announced.
• 📌 Mi 5s: same hybrid slot, but with an improved antenna for better network reception.

Important: you can’t install two SIM- + MicroSD cards at the same time, you have to choose between a second SIM or a memory extension, a key difference from later Xiaomi models (for example, the Redmi Note 10, where there are separate slots).

⚠️ Warning: Chinese versions of the Mi 5 (with domestic firmware) often have a lock on using two SIM- cards. Even if the slot physically supports Dual SIM, only one card can work software, due to local registration laws SIM.

💡

Before buying, check the region of the device through IMEI on the IMEI.info website. Chinese models (with the suffix "C" in the room) may have restrictions.

How to check the number of SIM- cards in your Mi 5

If you already own the Xiaomi Mi 5 but aren’t sure about the slot configuration, there are a few ways to find out:

1. Visual inspection: 🔍 Remove the tray for SIM- cards (use a paper clip or special key). 📏 The tray should be engraved with the words "Nano-SIM + Nano-SIM/MicroSD" or similar.
2. Through settings: 📱 Go to Settings → About Phone → General Information. 🔎 Find the item "IMEI" - if there are two, your device supports Dual SIM.

Special annexes:

• 📲 Install CPU-Z or AIDA64 from Google Play.
• 🔧 The phone section will indicate the number of SIM-slots.

If the settings show only one IMEI, but the slot is physically hybrid, then your model is software limited. This is typical for Chinese firmware. The solution is firmware of the global version of MIUI (but it is risky without experience!).

3. Hybrid slot: how to use correctly

The main feature of the Mi 5 is a hybrid slot, but it is also the main headache of users.

• 🔄 Switching between SIM and MicroSD requires the phone to be completely turned off. Hot replacement is not supported!
• 📶 When using two SIM- cards, the second card only works in 2G mode (unless VoLTE is activated).
• 🚫 Some memory cards (especially cheap ones) may not be recognized due to controller incompatibility.

Replacement algorithm:

⚠️ Warning: If the phone doesn't see the network after installing the second SIM- card, check:

• 🔌 Installation correctness (card must "click" in tray).
• 📡 Operator compatibility with Mi 5 frequency bands (the device does not support some 4G bands relevant in 2026).
• 🔄 Reboot the phone (sometimes a 2-3 reboot is required to activate the second SIM).

4. Regional differences: why your Mi 5 might have 1 SIM

Xiaomi Mi 5 came in different versions for different markets, which affects the number of supported SIM- cards:

• 🇨🇳 China (CN): Officially, 1 nano-SIM + MicroSD. Dual SIM is locked by firmware.
• 🌍 Global version (Global): Full Dual SIM (2 nano-SIM) + optionally MicroSD.
• 🇮🇳 India: Similar to the global, but with improved local 4G- band support.

How it affects the user: If you bought the Chinese version but want to use two SIM- cards, there are two options:

1. Switch to the global MIUI (risk of "bricking" in case of error).
2. Use a Dual SIM adapter (physically inserted into the slot, but can degrade the signal).

🔹 How to identify your Mi 5 region:

1. If you have the words "For China" in the box, it's the CN- version.
2. In settings: Settings → About Phone → MIUI version (on presence "CN" or "Global").
3. Through IMEI: The first digits point to the country of origin.

💡

Chinese versions of the Mi 5 can be unlocked for Dual SIM only through the firmware of the global MIUI.

Compatibility with modern networks (2026)

Xiaomi Mi 5 supports the following communication standards:

• 📶 2G: GSM 850/900/1800/1900 MHz.
• 📶 3G: WCDMA 850/900/1900/2100 MHz.
• 📶 4G LTE: Band 1/3/5/7/8/38/39/40/41 (depending on region).

Challenges in 2026:

• ❌ No support for 5G (expected for 2016 model)
• ❌ There are no modern bands 4G (e.g., Band 20, popular in Europe).
• ❌ When using two SIM- cards, the second only works in 2G unless VoLTE is activated.

🔹 How to check compatibility with your carrier:

1. Find out the frequency ranges of your operator (for example, MTS is Band 3/7/20).
2. Compare with the supported Mi 5 ranges (see specifications at GSM Arena).
3. If key bands are missing, internet speed will be limited.

💡

To improve connectivity in 2026, install the latest MIUI firmware (even if the phone hasn't been updated for a long time).

6.Alternatives: What to do if you need 2 SIM + MicroSD

If you are critical to use two SIM- cards and a memory card at the same time, consider these options:

• 🔄 Cloud storage: Move files to Google Drive, Mi Cloud or Yandex Disk. The Mi 5 supports up to 64GB of internal storage – enough for basic needs.
• 📱 USB-OTG Adapter: Connect the USB drive via the USB Type-C (requires an adapter). Reading speed will be slower than the MicroSD, but you won't have to sacrifice the SIM- card.
• 🔧 Dual SIM + MicroSD adapter: A physical adapter that allows you to insert two nano-SIM and MicroSD into one slot. Cons: signal degradation and the slot can warm up.

📌 The best choice for most:

If you need two SIM- cards, use them without a MicroSD. For files, plug in a OTG- flash drive as needed. This is safer than adapters and requires no firmware.

7.Typical mistakes and how to avoid them

The experience of Xiaomi Mi 5 users shows that most problems arise due to:

⚠️ Warning: Do not use metal objects (needles, pins) to retrieve the SIM- card tray! This can damage the contacts. Use only a special key or an unbended clip.

• 🔌 Smoothly inserted SIM- card: The tray should click. If that doesn't happen, the card won't be recognized.
• 📡 Incompatible operator: For example, in Russia, Tele2 uses Band 20, which is not supported by Mi 5.
• 🔄 No reboot: After replacing the SIM- cards, the phone needs to restart, otherwise the network may not appear.
• 📱 Firmware Failure: If the second SIM stopped working after the MIUI update, try resetting the network settings (Settings → SIM-maps and mobile networks → Reset).

🔹 What to do if the phone doesn't see SIM- card:

1. Check the card on another phone (it may be damaged).
2. Clean the contacts of the tray with alcohol (carefully, without pressing!).
3. Update the firmware to the latest version of MIUI.
4. If nothing helps, contact the service (possibly damaged slot).
