How much data do you need in China?

China blocks Google, WhatsApp, Instagram, Facebook, and most Western apps. A VPN is essential — and it needs mobile data to work.

Our recommendation: 10+ GB. VPN usage increases data consumption significantly. Budget generously.

Network coverage in China

China Mobile and China Unicom provide excellent 4G/5G coverage across the country. Even rural areas and the Great Wall have good signal. China has some of the world's best mobile infrastructure.

Important: Some eSIM providers route through Hong Kong SIMs, which may bypass the Great Firewall — meaning Google/WhatsApp work without VPN. Check with your provider.

Tips for using an eSIM in China

VPN is essential. China blocks Google Maps, WhatsApp, Instagram, and Facebook. Install a VPN app before arriving. Saily's built-in web protection may help but isn't a full VPN replacement.

Download Baidu Maps. Google Maps doesn't work in China. Baidu Maps or Amap (Gaode) are the local alternatives — they work without VPN.

WeChat is everything. Install and set up WeChat before arriving. China runs on WeChat — payments, messaging, booking, navigation.

Critical: Test your VPN connection before leaving for China. Some VPNs are blocked — have 2-3 options ready.
