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

While text messaging on apps like WhatsApp and Telegram generally works with eSIM Trails in Russia, voice and video calls on these and other VoIP platforms can be unreliable. Russian authorities, specifically Roskomnadzor, have been known to throttle or restrict VoIP services, making real-time communication challenging. We recommend using messaging for critical updates and being prepared for potential disruptions to voice/video calls when relying on these apps in Russia, even with a strong data connection.
