Modern smartphones such as iPhone, allow you to make calls even in places where regular cellular service is poor or absent altogether. The technology VoWiFi (Voice over Wi-Fi) is becoming the standard for communication quality, and the operator Megaphone is actively implementing this feature for its subscribers.

For product owners Apple This feature is integrated natively, making the calling process as transparent and convenient as possible. You don't need to download third-party apps like Viber or SkypeAll you need is a working SIM card and internet access.

In this article we will discuss in detail how to activate Wi-Fi calling on your device, what conditions must be met by the operator, and what to do if the feature isn't working. We'll also cover pricing and security issues so you can use your connection confidently and economically.
What is VoWiFi technology and how does it work?

For the subscriber Megaphone This means that the phone is using your home or office network to establish a connection with the other person.
The main advantage is that incoming and outgoing calls don't require cellular coverage. If you have a "dead zone" for a regular signal at home but have fast internet, the connection quality will be excellent. iPhone Automatically switches calls between Wi-Fi and cellular data without interrupting the connection if you move out of range of the router.
⚠️ Please note: Audio quality and connection stability directly depend on the speed and stability of your internet connection. At low internet speeds, voice may be interrupted.
It is important to understand that although the call is made over the Internet, it is charged according to the standard terms of your tariff plan. MegaphoneMinutes are used from the main package, not from internet traffic. This is a key difference from messengers, where traffic is used from gigabytes.
Requirements for connecting the service on iPhone
Before setting up your smartphone, you need to make sure that your hardware and SIM card meet the required standards. Not all models iPhone support work with VoWiFi in the networks of Russian operators, although modern models (starting with the iPhone 6 and newer) are technically ready for this.
The first step is to check your SIM card. If you're using an old SIM card from many years ago, you may need to replace it with a new one that supports 4G/LTE. This can be done free of charge at a dealership. Megaphone or through your personal account, ordering delivery.

Tariffing and traffic saving
One of the most frequently asked questions concerns the cost of such calls. Many users fear that minutes will be deducted from their internet package or billed separately. We hasten to reassure you: for subscribers Megaphone calls through VoWiFi are charged in the same way as regular voice calls.
If your plan includes a minute package, those will be used first. If the package is used up, the per-minute rate according to your plan is charged. There is no separate charge for the technology itself. It's not a separate service, but a method of signal delivery.
As for traffic, one minute of HD Voice calls consumes approximately 1 MB of data. This is negligible, but if you have limited data on your router, it's worth keeping in mind. However, providers typically don't limit this amount.
- 💰 Tariff plan minutes are being used up.
- 🌐 Internet traffic consumption is minimal.
- 🌍 When roaming, the rates are the same as at home (for calls to Russia).
It's important to note that if you're abroad and calling local numbers in your home country via Wi-Fi, it will be charged as an international call at your home region's rates, which can be expensive.
Possible problems and solutions
Despite the ease of setup, users may encounter situations where the feature doesn't activate or calls are dropped. The most common cause is blocked ports by the provider or router. Some corporate networks or public Wi-Fi (in cafes and airports) can block voice traffic.
The problem may also lie in the router's settings. If you have "Guest Network" mode enabled or a strict firewall, the connection may fail. Try switching to the main network or rebooting the router.
If you see a "No Service" message on your iPhone screen or the Wi-Fi calling icon doesn't appear, try the following:
- Toggle Airplane mode on and off.
- Restart your smartphone.
- Make sure your date and time settings are set to automatic.
Resetting network settings can sometimes help. This will delete saved Wi-Fi passwords, but it often resolves software conflicts. Here's how to reset: Settings → General → Transfer or reset iPhone → Reset → Reset Network Settings.
