Skype is a VoIP and video-calling platform offering chat, voice, video calls, SMS, and screen sharing across desktop and mobile. It integrates with Microsoft Teams and Outlook and supports global calling plans.

Skype is not blocked in China and is accessible via its Chinese-localized version operated through 21Vianet :contentReference[oaicite:5]. However, call quality can suffer due to cross-border routing, and users are advised to download the official version before entering China, as Apple/Google app stores in China redirect to a local variant with monitoring by local operators.

The information regarding service availability in China is provided for general reference purposes only. Due to the dynamic nature of network conditions and regulatory environments, the actual accessibility of these services may vary over time and by location. Users are advised to verify the current status independently.
