Do VoIP calls via WhatsApp, FaceTime, and similar apps function reliably in Russia with a Truly Roaming eSIM?

While text messaging on apps like WhatsApp and Telegram typically works, voice and video calls on these and other VoIP platforms can be inconsistent or throttled in Russia. This is often due to local network restrictions or government policies. A Truly Roaming eSIM provides a robust data connection, but even with strong data, VoIP call quality can be impacted by these external factors. For critical communications, consider backup methods or manage expectations regarding consistent high-quality video calls.
