Modern Honor smartphones offer a wide range of features that allow you to stay connected even in poor cellular signal conditions. VoWiFi (Voice over Wi-Fi) technology has become the standard, allowing voice calls over a wireless internet connection. This solution is ideal for rooms with thick walls, basements, or country houses where mobile coverage is poor.
Activating this feature on Honor devices doesn't require installing third-party apps, as it's built into the MagicOS system software. However, users often encounter a missing button in the menu or the inability to activate the feature due to carrier restrictions. In this article, we'll cover all the setup details, check plan compatibility, and troubleshoot potential connection issues.
It is worth noting that the sound quality when using Wi-Fi Calling Often outperforms standard voice calls thanks to the use of the wideband HD Voice codec. For this technology to work successfully, a stable internet connection with minimal latency is required. If your router is configured correctly and your data plan supports the service, you'll enjoy crystal-clear sound anywhere within the wireless network's coverage area.
Technological features of VoWiFi on Honor smartphones
Voice calling over Wi-Fi is based on IMS (IP Multimedia Subsystem) protocols, allowing voice traffic to be transmitted as regular internet data. On Honor smartphones running Android and the proprietary OS, this process is fully integrated into the standard dialing interface. The user will notice no difference in the call process, except for an icon in the status bar indicating the connection type.
A key advantage is seamless handover, or switching between networks seamlessly. If you leave Wi-Fi coverage during a call but reenter a strong cellular network, the call is not interrupted. The Honor system automatically redirects the data stream to the operator's base station, ensuring uninterrupted communication without loss of quality.
⚠️ Note: This feature depends not only on your phone's settings but also on your carrier's support for IMS technology. Make sure your plan includes VoWiFi, as it may be disabled by default on some legacy plans.
It's important to understand that this technology requires a specific network configuration. The router must correctly handle SIP protocols and not block ports required for voice transmission. Most home networks have default settings that allow VoWiFi to work, but in corporate or public networks with web-based authentication (Captive Portal), the feature may not work until the device is fully authorized.
How does switching between networks work?
Honor's system constantly monitors signal strength. If the Wi-Fi signal drops below a certain threshold and the cellular network signal is sufficient, the phone automatically switches to Wi-Fi. The reverse process is also possible: if you enter a room with poor cellular signal but have Wi-Fi, the phone will prompt or automatically switch to data calls.
Checking operator and tariff plan compatibility
The first step before attempting to activate the feature is to check if your mobile operator supports the service. Major carriers have already implemented VoWiFi support, but service terms may vary. On Honor smartphones, the list of supported carriers is frequently updated through system updates, so it's important to have the latest firmware version.
You must ensure the service is activated on your SIM card. In some cases, you may need to send a special USSD code or activate the option in your subscriber account. Without confirmation from your operator, the phone settings may be unavailable, or the feature may not work even if the switch is turned on.
- 📱 Megaphone: The Wi-Fi calling service is usually active by default on modern plans, but may require confirmation in the app.
- 📶 MTS: You must activate the "Wi-Fi Calling" service through your personal account or the USSD request specified on the official website.
- 🌐 Beeline: The feature is available to subscribers with postpaid and most prepaid plans, and activation often occurs automatically when you first connect to Wi-Fi.
- 🔴 Tele2: Support is available for most regions; please check the service status in your personal account.
It's also worth considering that making calls over Wi-Fi consumes data. While voice calls consume little data (approximately 1-2 MB per minute in high quality), this is important for users with limited data plans. However, if you're roaming, using Wi-Fi for calls can be significantly more cost-effective than standard voice plans, but roaming rules may vary between carriers.
Step-by-step instructions for enabling the feature in settings
If your carrier supports the technology and your data plan is active, you can proceed to the smartphone settings. The Honor interface may differ slightly depending on the MagicOS version, but the menu logic remains the same. First, make sure Wi-Fi is enabled and the device is connected to the internet.
Open the device's main settings menu. You'll need to find the section responsible for mobile network. For most current Honor models, the path looks like this: go to Settings, then select the item Mobile networkThis section displays SIM card settings and data transfer options.
⚠️ Note: If you use two SIM cards, you must check and activate the settings for each card separately. VoWiFi may be enabled on only one card or both simultaneously, depending on the processor model and software version.
Select the SIM card for which you want to enable calls. In the menu that opens, find the toggle Wi-Fi Calling (or "Wi-Fi Calling"). Move the slider to the active position. If the system asks for confirmation or prompts you to select a network priority (always use Wi-Fi or only when the signal is poor), select the appropriate option. "Prefer Wi-Fi" is generally recommended to save battery life when the cell signal is strong.
☑️ Activation algorithm
Once turned on, a special icon (often a telephone handset with a Wi-Fi symbol or the words "VoWiFi") should appear in the status bar next to the Wi-Fi indicator. This indicates the device has successfully registered with the carrier's IMS network. You can now make test calls.
Setting network priorities and parameters
The flexibility of the Honor system allows users to fine-tune the smartphone's network selection for voice calls. This is especially important in situations where the Wi-Fi signal is unstable but the cellular network is reliable. Incorrectly setting priorities can lead to connection drops or reduced audio quality.
The call settings menu often offers a choice of operating modes. You can prioritize Wi-Fi, which will force the phone to always attempt to make a call over the internet if available. Alternatively, you can use Wi-Fi only in areas with poor cellular coverage. The latter option is more efficient for maintaining a balance between call quality and battery life.
| Setting parameter | Description of action | Recommended value |
|---|---|---|
| Network priority | Selecting a primary channel for voice calls | Prefer mobile network (to save battery) |
| data roaming | Data roaming permission for VoWiFi | Included (if you are often abroad) |
| HD voice | Using high-quality codecs | Included |
| Video calls | Using Wi-Fi for video calling | At the user's discretion |
Video calling settings deserve special attention. Some carriers allow high-bitrate video streaming over Wi-Fi. Activating this feature may require a separate permission in the menu. Additional call settingsMake sure your front-facing camera and microphone have the necessary permissions to work in the background if you plan to multitask during a call.
Solving common connection problems and errors
Despite the technology's robustness, users may encounter a situation where the feature doesn't activate or the VoWiFi icon doesn't appear. The most common cause is a missing carrier profile in the phone's database. Honor, like other manufacturers, updates its list of supported carriers through security and system updates.
If the toggle is missing in Settings (grayed out or hidden), try resetting your network settings. This will delete saved Wi-Fi passwords and Bluetooth settings, but often restores hidden system flags. To do this, go to Settings → System & updates → Reset → Reset network settingsAfter rebooting, check the mobile network menu again.
Another possible cause is using a static IP address or specific DNS servers. VoWiFi requires DHCP to function correctly and establish a secure connection to the operator's servers. If you use a third-party DNS service (such as Google or Yandex), try switching to automatic address acquisition.
- 🔄 RebootSimply turning your smartphone off and on often solves the problem of frozen network services.
- 📶 Checking the router: Make sure that AP Isolation is not enabled on your router, which blocks devices from communicating within the network.
- 🛡️ Antiviruses: Third-party security applications may block SIP ports; try disabling your firewall during the test.
⚠️ Note: The settings interface and item layout may change after updating your operating system. If you don't find the described items, search for "Wi-Fi calling" or "VoWiFi" in the settings.
If all else fails, contact your carrier's support team. The network may require re-binding the service or replacing the SIM card with a newer one that supports LTE Advanced and VoWiFi standards. Older Mini-SIM cards may not work correctly with modern authentication protocols.
The Impact of Wi-Fi Calling on Battery Life and Connection Quality
Using Wi-Fi for voice communication impacts the smartphone's power consumption. Unlike a cellular modem, which is optimized for intermittent voice packet transmission, a Wi-Fi module can consume more power during an active connection, especially if the wireless signal is weak and the phone must constantly boost its transmit power.
However, in conditions with poor cellular reception (1-2 bars on the scale), using VoWiFi is often more energy-efficient. The smartphone doesn't waste resources constantly searching for a base station and strengthening the signal, instead operating reliably through an access point. Therefore, in areas with poor cellular coverage, enabling Wi-Fi Calling extends battery life.
Connection quality is directly dependent on the ping (latency) and jitter (variation in latency) of your internet connection. For a comfortable conversation, the ping should not exceed 100-150 ms. If you're using public Wi-Fi with a large number of connected users, audio quality may degrade, resulting in robotic distortion or audio stream dropouts.
Frequently Asked Questions (FAQ)
Do you charge per minute for Wi-Fi calls?
Yes, you're charged according to your base plan. Minutes are deducted from your voice package or charged at the same price per minute for on-net calls or calls to other numbers, just like a regular call. Internet traffic is also used, but usually in small amounts.
Is it possible to make calls via Wi-Fi while roaming?
Technically, this is possible, and it often allows you to avoid roaming charges, as the call is considered to originate from your home network (as if you were in your home city). However, you should check the terms with your carrier, as some may block VoWiFi abroad or require special activation.
Why did the VoWiFi icon disappear after the update?
After updating the firmware, your network settings may have been reset or your carrier profile may have changed. Try re-enabling the feature in your mobile network settings. If the icon doesn't appear, reset your network settings or contact your carrier support to check the service status.
Does the SIM-free feature work on the phone?
No, VoWiFi requires an active SIM card supported by your carrier. The phone uses the SIM card's data to authenticate with the carrier's IMS network over the internet.
