Connectivity, eSIMs & Essential Apps

Google services, WhatsApp, Instagram, and Reddit are inaccessible via mainland public networks. Here is how foreign travelers bypass this smoothly.

The Secret: Overseas Roaming eSIMs Bypass the GFW Automatically

When using an international roaming eSIM (such as Airalo, Nomad, Holafly, or 3HK), your mobile data is routed back through servers in Hong Kong, Singapore, or your home carrier. The Great Firewall does not filter international roaming cellular traffic.

Why NOT to buy a local Chinese SIM at the airport:

A local SIM card from China Mobile/Unicom connects directly to the mainland network. You will be subject to all blocking, requiring a VPN. Commercial consumer VPNs (ExpressVPN, NordVPN) suffer frequent disconnections during major events and sensitive dates.
