TeamViewer remains the world’s most widely used remote access and support platform, connecting over 2.5 billion devices and serving more than 600 million unique users. It enables full desktop control, file transfer, online meetings, and enterprise-grade IT support from anywhere on the planet.
Since 2022, TeamViewer GmbH (Germany) has enforced strict geographic restrictions under EU and U.S. regulatory pressure. In 2026 the policy is tougher than ever:
- New account creation is blocked for Russian and Belarusian phone numbers
- Existing accounts are suspended the moment a “sanctioned” IP is detected
- All Commercial, Business, and Enterprise licenses are automatically disabled for entities in Russia and Belarus
- Even the free personal version has severe functional limitations
KelVPN – a decentralized, quantum-resistant VPN – restores complete, stable, and secure access to TeamViewer with zero restrictions.
