Do WhatsApp, FaceTime, and other VoIP calls work effectively in Russia with an eSIM?

While messaging on apps like WhatsApp and Telegram generally functions in Russia, voice and video calls on these and other VoIP platforms can be inconsistent or even throttled. This isn't necessarily an eSIM issue, but rather related to local network policies. Some reports suggest that authorities may restrict VoIP services, making calls unreliable or difficult to connect. If VoIP calls are critical for your trip, consider alternative communication methods or be prepared for potential disruptions, regardless of your eSIM provider.
