Modern telecom operators are actively implementing technologies that allow voice calls to be made over the internet, and SberMobile is no exception. Wi-Fi Calling It's designed to improve connection quality in areas with poor cellular coverage, but in practice, users often find themselves forced to disable it. This may be due to a desire to save data, problems switching between networks, or simply a preference for a stable 4G/LTE signal.
The process for disabling this option isn't always obvious, as the settings may be located in different menu sections depending on your smartphone model and operating system version. In this article, we'll explain in detail how. Disable WiFi calls on SberMobile on various devices, we'll explain why this feature can interfere, and consider alternative ways to solve connection problems.
Before we dive into the technical details, it's important to understand that this service is often managed on the device itself, not in your operator account. The most correct and quickest way to disable the connection is through the smartphone's settings in the cellular communications section. Let's break down all the details of this process so you can easily manage your connection.
What is Wi-Fi Calling and why should you disable it?
Technology VoWiFi (Voice over Wi-Fi) enables voice traffic to be transmitted over a wireless internet network, using the same infrastructure as regular calls, but without accessing cellular base stations. For SberMobile subscribers, this means the ability to receive and make calls even in basements, remote villages, or offices with thick walls, where a standard LTE signal may be unavailable.
However, this has a downside, forcing users to search for an answer to the question of how to disable WiFi calling on SberMobile. Situations often arise where the phone "clings" to a weak router signal instead of switching to a stable 4G connection, resulting in interruptions or a complete lack of sound. Furthermore, with some plans or when roaming, using the internet for calls may be undesirable.
Another reason for abandoning the feature is incorrect caller ID functionality or the inability to use voice and data simultaneously on older phone models. If your smartphone doesn't support the technology VoLTE In parallel with Wi-Fi Calling, when there is an incoming call, the Internet may be temporarily disconnected, which causes inconvenience.
⚠️ Attention: Disabling Wi-Fi Calling may result in connection loss in areas where SberMobile's cellular network is completely unavailable but your home or office Wi-Fi is available. Ensure you have a strong 3G/4G signal in your area before disabling this feature.
Disabling the feature on Android smartphones
Owners of devices based on Android have the most flexible settings, but the location of the required switch can vary significantly depending on the manufacturer's shell (MIUI, OneUI, ColorOS, and others). In most cases, the configuration is accessed through the main system settings menu.
First, you need to go to the section Settings, then select the item Connections or Network and Internet. You should find the menu here. Mobile network or SIM cardsIt is in this section, usually next to the roaming or network type settings, that the switch is located. Wi-Fi callingOn some Samsung models, it can be found directly in the notification shade by long-pressing the Wi-Fi icon.
If you can't find the item you need, use the search in your phone's settings. Enter "Wi-Fi" or "Calls" in the search bar, and the system will automatically highlight the required section. On Xiaomi and Redmi devices, the path may look like this: Settings → SIM cards and mobile networks → Select a SberMobile SIM card → Use Wi-Fi for calls.
☑️ Check before disconnecting
After you've flipped the switch to the "Off" position, check the status bar on the screen. The handset icon with the Wi-Fi symbol should disappear, indicating a successful transition to the standard cellular network. If the icon remains, try turning it on and off. airplane mode to reboot the communication modules.
iPhone Settings: iOS 14 and later
For smartphone users Apple We're lucky with a more unified interface, where the settings are virtually identical across all models, starting with the iPhone 6 and newer. To disable WiFi calling on SberMobile on iOS, open the app. Settings and go to the section Cellular communications.
In the menu that opens, find the item Wi-Fi callingIf you have two SIM cards installed in your phone (or one physical and one eSIM), the system will ask you to select a specific SberMobile number for setup. After selecting the number, simply toggle the switch to the off position (gray).
It's important to note that the iPhone also has a "On Other Devices" feature that allows you to receive calls from your primary SIM card on your iPad or Mac. Disabling the primary setting Wi-Fi Calling automatically deactivates this option as well, but to be completely sure, it is better to check the related settings in the same menu.
Sometimes users encounter a situation where the setting isn't saved or the toggle switch resets. This may be due to configuration profiles or corporate restrictions if the device was issued by an employer. In such cases, it's necessary to check for management profiles in the section General → About device → Manage device.
Control via the SberMobile app
Although the main settings are located on the phone, the operator provides its own tool for controlling services - a mobile application SberMobileIt allows you to manage your plan, enable options, and, in some cases, influence call settings, although there may not be a direct "Disable Wi-Fi Calling" button depending on the phone model.
However, you can use the app to check whether you have any additional services activated that block or, conversely, force certain types of traffic. Go to the section Services and carefully review the list of enabled options. Sometimes you'll find settings related to roaming or international calling, which indirectly affect Wi-Fi Calling.
The app also offers a live chat with support. If you've tried all the settings on your phone but the feature still works or won't turn off, an operator can diagnose the line remotely. This is especially helpful if the problem is widespread in your region.
| Parameter | Setting up on your phone | Setting up in the app | Impact on tariff |
|---|---|---|---|
| Service status | On/Off | View only | No changes |
| Sound quality | HD Voice | Not regulated | Standard |
| Traffic consumption | No charges* | Not applicable | Unlimited** |
| Availability | Depends on the phone | Depends on the region | Enabled by default |
⚠️ Attention: While voice calls over Wi-Fi typically don't consume your basic data plan, FaceTime video calls or messaging apps running simultaneously will consume your data plan. Keep an eye on background apps.
Problems with sound and switching networks
One of the most common reasons users try to disable Wi-Fi calling on SberMobile is the smartphone's inconsistency when moving out of range of the router. The ideal scenario involves a seamless handover from Wi-Fi to the cellular network without interrupting the connection, but in reality, this process is often accompanied by delays or dropped calls.
The problem may be that the phone "sees" a weak Wi-Fi signal and tries to connect through it, ignoring the excellent 4G signal. This results in robotic voice quality, gaps, or echoes. In such cases, disable this feature in the settings. Mobile network is the only effective solution.
It's also worth mentioning the technology conflict. If your router operates in the congested 2.4 GHz band and neighboring networks create interference, the quality of your voice traffic will suffer. Unlike watching video, where buffering smooths out jerkiness, real-time voice communication requires a stable ping, which Wi-Fi calling can't always provide.
Technical details of the switch
The process of switching between Wi-Fi and LTE is called handover. Under the VoWiFi standard, it should be seamless. However, if the phone doesn't support the ANDSP protocol or the carrier's settings are incorrect, handover occurs with a drop call.
To diagnose the problem, you can perform a simple test: while at home with Wi-Fi Calling enabled, start walking toward the exit. If the call drops while you're still able to see the Wi-Fi network but are already receiving 4G, the switching algorithm is malfunctioning, and it's best to keep the feature disabled.
Impact on tariffs and roaming
The cost of Wi-Fi calling is often controversial. Officially, SberMobile, like many other Big Four operators, doesn't charge a separate fee per minute for Wi-Fi calls—it's deducted from your basic minute package or charged at the base rate, like a regular call. However, there are some important nuances.
The situation changes dramatically when you're roaming internationally. In many countries, Wi-Fi Calling calls are treated as if they were coming from your home region, saving you significant money. However, if you disable this feature, any calls you make or receive will be charged at expensive roaming rates.
On the other hand, if you are in Crimea or Sevastopol (where special roaming conditions apply for Russian operators), using Wi-Fi Calling may be the only way to avoid increased rates, since the call goes through the internet channel to the operator's gateway.
It's important to distinguish between Wi-Fi Calling and messaging calls (WhatsApp, Telegram, Viber). The former is used through the standard "Phone" interface and uses the SIM card number, while the latter is used through an in-app account. Their pricing is fundamentally different, and disabling one feature does not affect the other.
⚠️ Attention: Roaming pricing conditions are subject to change. Before traveling abroad, be sure to check your personal account or contact your operator for the current Wi-Fi Calling terms for your specific country to avoid unexpected charges.
Alternative solutions and optimization
If you've disabled WiFi calling on SberMobile but the connection quality remains poor, consider alternative options. Sometimes the problem lies not with the connection type, but with the smartphone's settings or firmware version. Updating the software to the latest version often fixes communication module bugs.
You can also try manually selecting a network. Go to your mobile network settings, disable automatic carrier selection, and wait for the list of available networks to appear. Select SberMobile or MCC 250 (Russia's country code), even if the phone offers other options. This can help secure a more stable frequency.
As a last resort, if voice communication issues persist, it might be worth replacing your SIM card with a new one (USIM). Older cards, issued several years ago, may not work properly with modern encryption and switching standards, leading to connection instability regardless of the network type.
Frequently Asked Questions (FAQ)
Will my minutes be lost if I turn off Wi-Fi Calling?
No, disabling this feature will not affect your plan or the number of minutes included in your package. Calls will simply be made over your regular cellular network, using up the same amount of minutes as before.
Is it possible to disable Wi-Fi Calling for only one SIM card?
Yes, if you have two SIM cards in your phone, the Wi-Fi Calling settings are in the menu Cellular communications (on iPhone) or SIM cards (On Android) are configured separately for each number. You can leave the feature enabled for one SIM card and disable it for the other.
Why does the call still go through Wi-Fi after disabling the feature?
It's possible your phone didn't have time to reconnect. Try turning on Airplane Mode for 10 seconds and then turning it off. Also, make sure your access point (APN) settings don't have any specific settings that prioritize Wi-Fi, although this is rare for SberMobile.
Does the shutdown affect mobile internet speed?
Disabling voice functionality shouldn't directly impact 4G/LTE speeds. However, if the phone was previously attempting to maintain a voice channel over Wi-Fi and placing a strain on the processor or radio module, disabling it may improve device performance.
Do I need to restart my phone after changing settings?
In most cases, changes take effect immediately. However, if you notice that the Wi-Fi handset icon persists or the connection is lost, restarting your device will clear the network settings cache and re-register.
