CoreESIM's technical analysis indicates that while text-based messaging on platforms like WhatsApp and Telegram generally functions in Russia, the performance of voice and video calls via these and other VoIP applications is frequently compromised. Network throttling, historically implemented by regulatory bodies such as Roskomnadzor, can severely degrade call quality and reliability. Users should anticipate potential disruptions, making consistent, high-fidelity VoIP communication challenging during their stay in Russia.
