Do VoIP apps like WhatsApp and FaceTime function reliably in Russia?

While text messaging through apps like WhatsApp and Telegram generally works in Russia, voice and video calls on these and similar VoIP platforms can often be unreliable or experience throttling. Travelers may encounter difficulties with consistent call quality or even connection issues, particularly since regulatory bodies have been known to impact their performance. For crucial communication, it's wise to have alternative methods or manage expectations regarding the seamlessness of VoIP calls during your trip to Russia.
