VPN for China
Astrill, LetsVPN, and NordVPN are the most reliable VPNs in China in 2026; install before arrival because the App Store blocks downloads inside China.
Portable WiFi
Rent a portable 4G/5G WiFi hotspot at the airport for ¥30–80/day, returnable at any major airport, useful for groups of 2–4 travelers.
Translation Apps
Pleco (offline dictionary) plus Apple Translate or Google Translate covers 95% of in-person translation needs; download Chinese offline pack before flying.
