Xiaomi smartwatches have long ceased to be just fitness trackers β modern models allow not only to track the pulse or steps, but also to call directly from the wrist, like on a classic phone. Some are limited to incoming notifications, others require a smartphone connection, and still others operate fully autonomously. SIM-In this article, we will understand what kind of Xiaomi watches can ring in 2026, how to set up voice communication and what to look for when choosing a model.
It is important to understand that the possibility of calls depends on three key factors: the hardware platform (whether the watch has a microphone, speaker and modem), the firmware version (some features are added later through updates), and the region of sale (in China and global versions, the feature set may differ). For example, the Mi Band 7 Pro in China supports calls via Bluetooth, and in the European version this option is blocked. We collected current data on all lines from the budget Mi Band to the flagship Xiaomi Watch.
1.What Xiaomi smartwatch models support calls?
The list of devices capable of receiving and making calls is divided into two categories: autonomous (with its own) SIM-and smartphone dependent (calls via Bluetooth). Below is a complete list of current models with an indication of the type of communication.
- π Autonomous (SIM-map: Xiaomi Watch S3, Xiaomi Watch S2, Xiaomi Watch 2 Pro, Redmi Watch 3 Active (LTE-version).
- π΅ Through Bluetooth (smartphone required): Xiaomi Watch 2, Mi Band 8 Pro, Mi Band 7 Pro (Chinese version only), Xiaomi Smart Band 7 Pro (global version - no calls).
- β No Call Support: All Mi Band models up to version 7, Xiaomi Mi Watch Lite, Redmi Watch 2.
The Xiaomi Watch S3 and Watch 2 Pro stand out β they are equipped with a built-in eSIM modem, which allows you to use the main phone number without a physical SIM. However, to activate eSIM, you will need operator support (in Russia for 2026 this is MTS, Beeline and Tele2).
How to call on the Xiaomi watch: technical nuances
Calling patterns vary depending on the model, and let's look at the key scenarios:
- Offline calls (SIM/eSIM): The watch connects to the cellular network on its own. For example, the Xiaomi Watch S3 can accept calls even if the smartphone is turned off.
- Bluetooth calls: The watch uses a smartphone connection as a headset. For example, the Mi Band 8 Pro allows you to respond to incoming calls, but can not make outgoing ones without a phone.
- Limited functionality: Some models (such as the Xiaomi Watch 2) can only receive incoming Bluetooth, but do not support dialing from the screen.
The important thing is that the quality of the Bluetooth watch depends on the distance to the smartphone. If you're more than 10 meters away, there's a cliff, and in standalone models, the quality is determined by the coverage of the operator's network, just like in a regular phone.

If your watch supports eSIM, check compatibility with the operator ZARANEO. For example, MTS has a list of supported devices - if your model is not there, eSIM will not activate.
3. Step-by-step call setup on Xiaomi watches
The instructions are different for standalone and Bluetooth models, and below are the universal steps for the most popular devices.
For standalone watches (SIM/eSIM):
βοΈ Setting up SIM Xiaomi Watch S3
If you use eSIM:
- Download the Mi Fitness app (for global versions) or Xiaomi Wear app (for China).

It's simpler to pair your watch with your smartphone via Mi Fitness and allow access to contacts/microphones, such as the Mi Band 8 Pro:
- Open Mi Fitness β Profile β My Device β Notifications.
- Activate the Incoming Calls option.
- In Android settings, give the application the rights to Phone and Microphone.
- On the clock, it will be possible to receive calls swipe to the right on the incoming notification.
What to do if the calls donβt work?
4. Model comparison: Which Xiaomi watch is best for calls?
To choose the best model, compare the key parameters in the table:
| Model | Type of communication | Autonomous calls | eSIM | Opening hours (calls) | Price (2026) |
|---|---|---|---|---|---|
| Xiaomi Watch S3 | LTE + Bluetooth | β (SIM/eSIM) | β | 12 hours | ~25 000 β½ |
| Xiaomi Watch 2 Pro | LTE + Bluetooth | β (eSIM) | β | 8 hours | ~20 000 β½ |
| Mi Band 8 Pro | Bluetooth | β (just-in) | β | 6 hours | ~7 000 β½ |
| Redmi Watch 3 Active (LTE) | LTE + Bluetooth | β (SIM) | β | 5:00 | ~9 000 β½ |
Conclusion: For a full replacement phone suitable Xiaomi Watch S3 or Watch 2 Pro with eSIM. If you need a budget model for receiving incoming β Mi Band 8 Pro. Note that the time in call mode is much lower than in the fitness tracker (for example, Watch S3 will live up to 12 days without calls, but only 12 hours with active use of communication).

The standalone SIM-card watch (Xiaomi Watch S3, Redmi Watch 3 Active) is suitable for athletes or those who want to leave the phone at home. Bluetooth models (Mi Band 8 Pro) - only for the convenience of receiving incoming.
5. Limitations and pitfalls
Even in top Xiaomi models there are nuances that are rarely talked about in reviews:
β οΈ Note: In Russia, many operators (for example, MegaFon) do not support eSIM for smart watches. S3 Check this with your provider, otherwise the call function will have to be activated through physical contact. SIM.
- π Fast discharge: Autonomous calls eat up the battery 3-5 times faster. For example, Redmi Watch 3 Active will run out in half a day if you actively call.
- πΆ Poor coverage: The watch uses miniature antennas, so communication can be worse than on a smartphone (especially in basements or outside the city).
- π Sound quality: Watch speakers and microphones are inferior to phones, and noisy places will make it difficult to hear the other person.
- π Regional restrictions: Chinese versions of Mi Band 7 Pro support calls, but global versions do not (even after firmware).
Another important point: Call apps. Xiaomi's default watch uses a standard Android phone module, but some models (like the Watch S3) can install WhatsApp or Telegram for voice messages, but video calls are not supported on any model, only audio.
6. Alternative ways to communicate on Xiaomi watches
If your model doesnβt support classic calls, there are workarounds:
- π¬ Voice Messages: In Mi Band 8 Pro, you can record a voice message and send it via Mi Fitness as a file.
- π± Remote access: On some firmware (e.g. Xiaomi Watch) S1) There is a function "Remote view" - you can see the incoming call on the clock and receive it on the phone lying in another room.
- π Redirect: Set up a smartphone to redirect calls to another number (for example, to a work phone), and notifications will be duplicated by the clock.
For Mi Band 6/7 owners (without a microphone), there is a trick: you can connect a Bluetooth headset to a watch (for example, Xiaomi AirDots) and take calls through it, using the phone as a bridge.
- Couple the headset with the phone.
- In Mi Fitness, activate Call Notification.
- When the call is in, the sound will automatically switch to the headset.
7. Frequent errors and their solution
Problems with calls on Xiaomi watches are usually due to incorrect settings or firmware.
β οΈ Warning: If after the firmware update, calls to Mi Band 8 Pro are missing, try resetting the clock to factory settings via Settings β System system β Reset: In 30% of cases, this restores function (Mi Fitness application data will not be affected).
| Problem. | Possible cause | Decision |
|---|---|---|
| Incoming calls are not working | No microphone rights in Mi Fitness | Go to Android settings β Applications β Mi Fitness β Permissions and turn on the Microphone and Phone. |
| You can't make an outgoing challenge. | The model does not support dialing (for example, Mi Band 8 Pro) | Use a voice assistant on your phone (e.g., OK, Google, call your mom). |
| SIM card not defined | Incorrect SIM format (Nano-SIM required) | Cut the SIM to nano format or use an adapter. |
| I can't hear the interviewer. | Contaminated microphone or speaker | Wash the holes with a soft brush (do not use alcohol!). |
If none of these methods worked, check the firmware region, for example, Chinese versions of the Xiaomi Watch S3 can block calls when connecting to Russian carriers, in which case flashing to the global version will help (but this will void the warranty!).
