How do VoIP services like WhatsApp and FaceTime perform with eSIM Routes plans in Russia?

While messaging functionalities on platforms like WhatsApp and Telegram generally operate, voice and video calls through these and other VoIP applications often experience throttling or reduced reliability within Russia. Since 2025, regulatory bodies like Roskomnadzor have been known to actively manage internet traffic, which can impact the performance of VoIP calls. Consequently, while an eSIM Routes plan will provide data connectivity, the quality of real-time communication via VoIP apps might be inconsistent, requiring travelers to adjust their communication strategy accordingly.
