We will pay special attention to hidden operator settings that MegaFon does not advertise in open sources — they'll help you avoid common connection errors. If you frequently visit areas with poor coverage or travel abroad, this guide will save you time and frustration.

What are Wi-Fi calls and how do they work with MegaFon?

Wi-Fi Calling (or VoWiFi) is a technology that allows you to make calls and send messages over a wireless network instead of a cellular network. Your smartphone connects to the internet via Wi-Fi, and the operator (in this case, MegaFon) routes the voice traffic over an IP network. This means:

• 📞 Calls are charged as usual, according to your minute package rate
• 🌍 Works in roaming (but requires separate activation)
• 🔄 Automatically switches between Wi-Fi and cellular networks (if the 4G/5G signal is stable)
• 📱 All standard features are supported: caller ID, call waiting, conference calling

MegaFon began rolling out the technology en masse in 2019, but many subscribers still aren't aware of its existence. The main difference from messaging apps (like WhatsApp or Telegram) is that calls are made from your main number, not through an in-app account. This means you'll be seen as usual, without any prefixes like "+79xx via WhatsApp."

Technically, the service operates on the basis of the standard IMS (IP Multimedia Subsystem), which is integrated into modern 4G/5G networks. MegaFon uses it to provide VoLTE (voice over LTE) and VoWiFi (voice over Wi-Fi). If your phone supports both technologies, they will work synchronously.

Troubleshooting: Why Wi-Fi Calling Isn't Working

Even if you've configured everything correctly, problems may still occur. Here are some common errors and how to fix them:

If none of the above methods help, reset your network settings:

• On iPhone: Settings → General → Transfer or reset → Reset → Reset network settings.
• On Android: Settings → System → Reset → Reset Mobile Network/Wi-Fi/Bluetooth.

Wi-Fi Calling While Roaming: How to Save

One of the key features of Wi-Fi Calling is the ability to make calls at your home rate even when abroad. However, there are some caveats:

• ✈️ In most EU and Asian countries, the service works automatically.
• 🌎 In the US, UAE, and Turkey, manual activation via USSD request may be required *135#.
• 💰 Calls are charged as within the network (if you are calling a Russian number).
• 📵 Must be enabled for incoming calls data roaming (even if you don’t use mobile internet).

To avoid unexpected expenses:

1. Before your trip, check the list of countries that support Wi-Fi roaming on the MegaFon website.
2. Turn it off automatic roaming in your phone settings if you don't plan to use local networks.
3. Use instant messengers (WhatsApp, Telegram) for international calls – they are cheaper than VoWiFi when roaming.

Important: In some countries (for example, China), Wi-Fi calls may be blocked by the provider. In this case, a VPN can help, but its use must comply with local laws. MegaFon does not guarantee service availability in regions with strict internet censorship.

Wi-Fi Calling Alternatives: When You Need Them

If your phone doesn't support VoWiFi or you're experiencing unsolvable issues, consider alternative internet calling methods:

• 📱 MegaFon-TV Calls (Android/iOS app) – allows you to make calls over Wi-Fi without being tied to a SIM card, but requires registration.
• 💬 WhatsApp/Telegram — free calls, but the subscriber will see your messenger account, not your phone number.
• 📞 Google Voice (for Android) - issues an American number, but allows calls over Wi-Fi at local rates.
• 🔄 SIP clients (for example, Zoiper) - for advanced users, requires manual configuration.

The main drawback of these alternatives is the lack of integration with native calling. You'll have to ask subscribers to save a new number or use a separate app. MegaFon's Wi-Fi Calling has the advantage of being transparent: your contacts won't even notice the difference.

If you frequently call landlines (for example, banks or government agencies), VoWiFi remains the only reliable option. Most organizations block calls from virtual numbers (WhatsApp, SIP), but allow calls from mobile phones.
