INTERNET CONTROLS AFFECTING CALLING
What's Restricted in China

VoIP & Messaging App Blocks
Consumer VoIP apps and many messaging services are blocked or heavily throttled by the Great Firewall.
- WhatsApp, Telegram, Signal unavailable or unreliable
- Skype, Google Meet, Zoom calling restricted
- WeChat calling available but monitored
Commonly blocked or restricted

State-Controlled Telecom Market
Three state-owned carriers dominate; international routing is centralized and monitored.
- Limited carrier choice for consumers
- All international calls route through state infrastructure
- Call quality and availability depend on carrier load
Major carriers
China Mobile, China Unicom, China Telecom control ~99% of market.
International routing
All outbound calls pass through state-monitored gateways.
