Pourquoi mon VPN ne fonctionne pas en Chine ?
Last updated:
⚠️ SYMPTOM
Vous êtes arrivé en Chine, vous avez ouvert votre VPN et il ne se connecte pas du tout, ou il se connecte mais aucun trafic ne se charge.
🔍 MOST LIKELY CAUSE
Le Great Firewall de Chine sonde et bloque activement la plupart des protocoles VPN commerciaux ; les VPN gratuits et les configurations OpenVPN non maintenues sont bloqués en quelques jours après l'arrivée.
✓ HOW TO FIX
Installez deux VPN payants avec obfuscation (Astrill StealthVPN, LetsVPN ou NordVPN obfuscated) AVANT d'entrer en Chine, et changez de serveur lorsqu'un serveur devient indisponible.

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.
SIM & eSIM
Tourist eSIMs from Airalo, Holafly, and Nomad give 7–30 days of China data for $5–$30 without passport registration at a Chinese store.
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.
