Calls via Wi-Fi on Apple Watch - This is not just a convenient feature, but a real necessity for those who often leave iPhone at home or facing poor mobile network coverage. Since the introduction of this option in watchOS 5 Since 2018, it has undergone numerous changes, from support for new models to eSIM integration. However, many users are still either unaware of its existence or encounter problems setting it up.
In this article we will figure out, Which Apple Watch models support Wi-Fi calling?, how to activate them correctly (including without being tied to iPhone), what tariffs are required from operators, and what to do if the connection is constantly dropped. We will pay special attention Hidden settings in watchOS 10+ that allow you to prioritize Wi-Fi calls over cellular data This feature is rarely mentioned, although it solves the problem of breaks in the subway or offices with thick walls.
If you've already tried making calls over Wi-Fi and nothing worked, don't blame your watch. In 80% of cases, the problem lies in the settings. iPhone, router, or data plan. We've compiled all the common errors and fixes, including rare bugs. watchOS, which even Apple support doesn't always know about.
Which Apple Watch models support Wi-Fi calling?
Not all Apple Watch can make calls via Wi-Fi - this function depends on the generation of the watch and the availability cellular moduleHere is a complete list of compatible models:
- 📱 Apple Watch Series 3 (Cellular) is the first model to support Wi-Fi Calling, but with limitations (requires iPhone 6 or newer).
- 📱 Apple Watch Series 4–6 (Cellular) - full support, including call transfer between devices.
- 📱 Apple Watch SE (1st generation) (Cellular) - a budget option with the same capabilities as Series 5.
- 📱 Apple Watch Series 7–9 And SE (2nd generation) - improved connection stability and support
Wi-Fi 6. - 📱 Apple Watch Ultra / Ultra 2 - Better battery life during Wi-Fi calls thanks to an optimized chip.
Important: Even if your watch is on this list, check it out. serial number On the Apple website. Some models for certain regions (e.g., China) may not support Wi-Fi Calling due to local carrier restrictions.
Models without Cellular (GPS-only) can technically connect to Wi-Fi, but won't be able to call - they just duplicate notifications from iPhoneException: if you have iPhone nearby, the watch will use its connection for calls, but this is no longer an autonomous mode.
Tariffs and operators: what do you need for Wi-Fi calling?
Even if your watch supports the feature, it won't work without the right data plan. In Russia and the CIS, the situation with Wi-Fi Calling is Apple Watch This is complicated by the fact that not all operators officially support this technology. Here are the current figures for 2026:
| Operator | Wi-Fi Calling Support | Additional terms and conditions | Price |
|---|---|---|---|
| MTS | ✅ Yes | Smart tariff or higher, eSIM for watches | From 0 ₽ (included in the tariff) |
| Beeline | ✅ Yes | "Everything is simple" or "Unlimited" tariff | +100 ₽/month for eSIM |
| Megaphone | ✅ Yes | Any tariff with the "Wi-Fi Calling" option | From 50 ₽/month |
| Tele2 | ❌ No (iPhone only) | — | — |
| Yota | ✅ Yes | Unlimited tariff | Included |
Key points:
- 📶 eSIM is mandatory for autonomous calls (without iPhone). Without it, the watch will only be able to ring when connected to iPhone via Bluetooth.
- 💳 Wi-Fi Calling ≠ VoLTESome carriers enable VoLTE by default, but it's a different technology (calls over 4G). Wi-Fi requires separate activation.
- 🌍 Roaming: On most plans, Wi-Fi Calling only works within your home network. Outgoing calls may be blocked abroad.
⚠️ Attention: Operator terms and conditions may change. For example, in 2026, Beeline temporarily suspended Wi-Fi Calling support for new customers due to a billing update. Before setting up, check the current rates in your personal account or with your operator.

Problems and errors: why aren't Wi-Fi calls working?
Even with proper setup, users often encounter common errors. We've compiled the most common ones and how to fix them:
| Problem | Possible cause | Solution |
|---|---|---|
| The call does not connect | Wi-Fi Calling is disabled on iPhone | Check it out Settings → Phone → Wi-Fi Calling |
| There is no sound when calling | The Bluetooth headset is connected to the iPhone | Turn it off or select the clock as the sound source |
| "No service" on the watch | Problems with eSIM or tariff | Restart your watch and check your balance. |
| Calls are disconnected | Weak Wi-Fi signal or router settings | Change the Wi-Fi channel to 5 GHz or enable QoS |
Complex cases:
- 🔄 eSIM activation error: If the watch cannot activate mobile communication, try removing and adding the eSIM again through

IPv6. - 🔒 Operator blocking: if calls work through iPhone, but not through the watch - call support and ask them to check the IMEI link of the watch to your number.
What should I do if my carrier doesn't support Wi-Fi Calling?
If your operator does not support this function (for example, Tele2), you can use workarounds:
1. FaceTime Audio Calls (works over Wi-Fi, but requires FaceTime from the subscriber).
2. VoIP applications (WhatsApp, Skype, Zoom) - they have versions for watchOS.
3. Call forwarding to another number that supports Wi-Fi Calling (configured in the operator's personal account).
The downside of these methods is that the called party will see a different number (not your main one).
How to improve Wi-Fi calling quality on Apple Watch?
If calls go through but the sound is interrupted or there is an echo, the problem lies in network settingsHere's what you can do:
1. Optimize your router:
- 📶 Switch to range
5 GHz- it is less loaded and more stable for voice communication. - 🔄 Turn on
QoS (Quality of Service)in the router settings and set priority for Apple devices. - 🔌 Disable energy saving on your router (this feature may interrupt the connection).
2. Set up your Apple Watch:
- 🔊 In
Settings → Sounds and Hapticsturn it offSpeaker cover- This improves the volume. - 📱 In
Settings → Phone → Wi-Fi Callingturn on the optionPrefer Wi-Fi Calling(available from watchOS 10).
3. Check for interference:
- 🚪 Make sure there are no thick walls or metal objects between you and the router.
- 📵 Turn off other devices using Wi-Fi (especially torrents or online games).
Is it possible to make Wi-Fi calls without an iPhone?
Yes, but with reservations. Autonomous Wi-Fi calling (without reference to iPhone) are possible only if three conditions are met:
- Watch model — Apple Watch Cellular (any generation).
- Active eSIM — the watch must be linked to the operator’s tariff (even if iPhone turned off).
- Connecting to Wi-Fi — the watch must be within the coverage area of a saved network (for example, home or work).
How does this work:
- 📱 If iPhone nearby - the watch uses its connection (Bluetooth/Wi-Fi) for calls.
- 📡 If iPhone turned off or far away - the watch connects to Wi-Fi directly via eSIM.
- 🚫 Without eSIM and without iPhone Wi-Fi calling impossible (even if the watch is connected to the network).
An important nuance: in the mode without iPhone Some features may be limited. For example, Series 3 Call transfer between devices does not work, and on Ultra 2 You may not have access to voicemail.
⚠️ Attention: If you plan to use your watch completely autonomously (for example, for running without your phone), make sure your carrier supports it. simultaneous operation of an eSIM on a watch and a physical SIM card in an iPhoneSome tariffs (for example, corporate ones) block such duplication.
Wi-Fi Calling vs. VoLTE: Which is Better for Apple Watch?
Many people are confused Wi-Fi Calling And VoLTE, although these are different technologies. Here are the key differences:
| Parameter | Wi-Fi Calling | VoLTE |
|---|---|---|
| Connection type | Wi-Fi (Internet) | 4G/5G (mobile network) |
| Connection quality | Depends on the router | More stable in motion |
| Battery consumption | Above (constant Wi-Fi) | Below (optimized) |
| Operator support | Limited (not all) | Wider (most) |
| Working without an iPhone | Yes (with eSIM) | Yes (with eSIM) |
When to choose Wi-Fi Calling:
- 🏠 You often make calls at home/in the office where there is stable Wi-Fi.
- 🚇 In the metro or underground parking lots where there is no 4G coverage.
- 🌍 While roaming (if the operator doesn't block the function).
When to choose VoLTE:
- 🚗 On the move (in a car, on the street).
- 🔋 If battery saving is important.
- 📶 In places with poor Wi-Fi but good 4G.
On Apple Watch Both technologies can work in parallel: the watch will automatically choose the best option. However, in watchOS 10+ an opportunity arose force Wi-Fi priority - This is useful if you know that your router is more stable than the local cellular network.
